co benefit of carbon mitigation on resource use in china abstract on one hand natural resources and energy provide the basis for life on earth but waste and emissions are produced during their throughput on the other hand china as the most populous country and an emerging economic powerhouse has taken on the challenge of hitting peak carbon dioxide co2 emissions by 2030 pursuing resource co benefits from carbon mitigation is an effective approach for china on the road to achieving the 2030 goal in this study we combine the computable general equilibrium cge model and the economy wide material flow accounts or analysis ew mfa method to estimate china s future co2 emissions and resource consumption and their co benefit effect three scenarios are analyzed business as usual bau nationally determined contributions ndc and the scenario of achieving the 2 degree target 2deg we find that both the ndc and 2deg targets can be achieved by 2030 without a significant compromise in economic growth with the effect of carbon mitigation china s resource consumption would rise by a factor of 1 7 bau 1 6 ndc and 1 5 2deg during 2012 2030 and the reduction in co benefits of metal ores nonmetallic minerals and fossil fuels would be 0 6 billion tons and 1 4 billion tons 0 8 billion tons and 2 0 billion tons and 2 6 billion tons and 4 6 billion tons for ndc and 2deg respectively sectoral disparity indicates that sectors with high emissions and resource consumption include traditional heavy industrial sectors and energy related sectors for which additional mitigation policies should be employed not only because they offer the most co benefit effects but they also have the least cost

a first empirical comparison of energy footprints embodied in trade mrio versus plum abstract the ecological footprint as an indicator that accounts for human demand on global bioproductivity sets out to quantify the impacts associated with consumption in a given country including the impacts associated with trade the national footprint accounts nfa by global footprint network gfn calculate trade embodied footprints by multiplying yield and embodied energy factors with mass volumes of traded goods in a product land use matrix plum this article compares energy footprints embodied in trade from and to the united kingdom in 2002 as calculated by the nfa plum with the results from a recently developed multi region input output model mrio for the uk although totals for imports and exports are comparable breaking down the results by economic sectors reveals large differences and hardly any correlation between the two methods the omission of trade in services especially transport services and upstream impacts of energy goods fossil fuels and the use of inappropriate embodied energy factors in the nfa plum method are identified as the main reasons for these differences in the light of the results it seems that a comprehensive footprint account of trade can better be achieved with an input output based approach i conclude that mrio models once fully developed will be particularly suitable in the future to estimate the ecological footprints of imports and exports of nations with the possibility to track their origin via inter industry linkages international supply chains and multi national trade flows

balance issues in input output analysis a comment on physical inhomogeneity aggregation bias and coproduction recently merciai and heijungs 2014 demonstrated that monetary input output io analysis can lead to system descriptions that do not conserve mass when the assumption of homogeneous prices is violated they warn that this violation of basic balance laws can lead to biased estimates of environmental impacts and they therefore recommend performing io analysis in a physically accounted framework we take a broader scope on this issue and present price inhomogeneity as a special case of product mix inhomogeneity we demonstrate that even a fully physically accounted io analysis or lifecycle assessment will violate balance laws if it suffers from inhomogeneous aggregation the core issue is not whether a system is described using monetary or physical units but rather whether product groups are too aggregated to allow for the concurrent respect of energy mass financial and elemental balances we further analyze the link between the violation of physical balances and the introduction of biases we find that imbalances are neither a necessary nor a sufficient condition for the presence of systematic errors in environmental pressure estimates we suggest two ways to leverage the additional explanatory power of multi unit inventory tables to reduce instances of imbalances and aggregation biases

firm ownership china s export related emissions and the responsibility issue abstract china s co 2 emissions and those embodied in its exports have been extensively studied one often neglected aspect is the prevalence of foreign invested enterprises fies in china s exports for which a substantial portion of benefits return to the investing countries in this paper we revisit china s export related co 2 emission responsibilities by viewing them from a new gross national income perspective using a recently developed environmental input output framework one which distinguishes firms by ownership and trade mode we find that china s co 2 emissions responsibility for each yuan of national income from fie exports is actually higher than that attributable to chinese owned enterprise coe exports the result has a somewhat surprising implication it suggests another source of conflict between china s and global interest in reducing co 2 emissions from a purely chinese as opposed to global standpoint a higher share of exports by coes rather than fies is favorable even though coes emit more co 2 when producing each unit of exports this finding should sound an additional warning to those who still think that global climate change mitigation can be effectively pursued by allocating country by country emissions responsibility

does ecologically unequal exchange occur the hypothesis of ecologically unequal exchange posits that low and middle income developing nations maintain an ecological deficit with wealthy developed nations exporting natural resources and high impact commodities thereby allowing wealthy economies to avoid operating ecologically impactful industries at home in this survey we assess the footprint of consumption of 187 countries using eight indicators of environmental pressure in order to determine whether or not this phenomenon occurs we use input output analysis with a new high resolution global multi region input output table to calculate each trading pair s balance of trade in biophysical terms of ghg emissions embodied water and scarcity weighted water content air pollution threatened species human appropriated net primary productivity total material flow and ecological footprint we test three hypotheses that should be true if ecologically unequal exchange occurs one the inter regional balance of trade in biophysical terms is disproportional to the balance of trade in financial terms we find this is true though not strongly so two exports from developing nations are more ecologically intensive than those from developed nations we find this is true three high income nations disproportionately exert ecological impacts in lower income nations we find this is false high income nations are mostly exporters not importers of biophysical resources

measuring financial integration via idiosyncratic risk what effects are we really picking up we study the method proposed by flood and rose fr 2004 2005 for checking for financial integration by estimating the risk free rate using the idiosyncratic component of individual stock returns performing simulations with data with a known return generation process we find that the fr methodology produces poor estimates of the risk free rate and hence the fr method fails to accept integration when true we then show analytically that the fr method actually provides an estimate of the market return and conclude the fr methodology would also falsely accept integration as long as the market returns in the two markets do not differ widely

global patterns of materials use a socioeconomic and geophysical analysis abstract human use of materials is a major driver of global environmental change the links between materials use and economic development are central to the challenge of decoupling of materials use and economic growth dematerialization this article presents a new global material flow dataset compiled for the year 2000 covering 175 countries including both extraction and trade flows and comprising four major material categories biomass construction minerals fossil energy carriers and ores industrial minerals first we quantify the variability and distributional inequality gini coefficients in international material consumption we then measure the influence of the drivers population gdp land area and climate this analysis yields international income elasticities of material use finally we examine the coupling between material flows and between income and material productivity measured in economic production per tonne material consumed material productivity is strongly coupled to income and may thus not be suitable as an international indicator of environmental progress a finding which we relate to the economic inelasticity of material consumption the results demonstrate striking differences between the material groups biomass is the most equitably distributed resource economically the most inelastic and is not correlated to any of the mineral materials the three mineral material groups are closely coupled to each other and economic activity indicating that the challenge of dematerializing industrial economies may require fundamental structural transformation our analysis provides a first systematic investigation of international differences in material use and their drivers and thus serves as the basis for more detailed future work

optimization analysis of carbon emission rights allocation based on energy justice the case of china abstract carbon emission rights allocation affects the effective operation of carbon trading system and then the achievement of energy saving and emissions reduction objectives reasonable allocation scheme should meet the principle of justice carbon emission rights allocation based on energy justice is a novel and worth discussing subject this paper explores the optimization of carbon emission rights allocation based on energy justice the justice based model is built with the aid of gini coefficient the way to optimize allocation scheme with constraints of population ecological productive land fossil energy resources and gdp is discussed results show that fossil energy resources and ecological productive land play more important role in the allocation the prime example is inner mongolia its quota percentage change reaches up to 150 01 as the gdp and population growth rate are fixed in a given interval the quota allocation in eastern china shows some interesting results when the gdp growth rate is 6 25 the quotas of eastern china will not change with varying population growth rate the allocation will enter a relative stable stage as the population growth rate is greater than or equal to 6 4 these results can provide china with experience to deal with the new problem appeared in carbon trading system like two children policy and the new normal of economic growth

a pathway to circular economy developing a conceptual framework for complex value assessment of resources recovered from waste the transition to a circular economy where the value of resources is preserved in the technosphere must be supported by policies and operational decision making based on evidence existing methods used to provide this evidence e g lca lcsa cba are not robust enough to adequately address the creation and dissipation of systemic and multidimensional value that spans the social environmental economic and technical domains this study proposes a novel conceptual approach that seeks to assess how complex value is created destroyed and distributed in resource recovery from waste systems this approach expands beyond conventional methods of estimating value it combines scientific and engineering methods with a socio political narrative grounded in the systems of provision sop approach and provides a comprehensive analytical framework for making the transition to a resource efficient future this framework has the potential to connect bottom up and top down approaches in assessing resource recovery from waste systems and address systemic challenges through transparency and flexibility while accounting for the dynamic and non linear nature of commodities flow and infrastructure provision in the overall system this creates the pathway towards circular economy and lays the foundations for future advances in computational and assessment methodologies in the field of rrfw

pathways to a low carbon economy estimations on macroeconomic costs and potential of carbon emission abatement in beijing abstract developing reliable frameworks to estimate the potential of co2 emission abatement and its associated costs merits urgent attention this study aims to estimate the potential as well as macroeconomic costs of co2 emission abatement in beijing using the industrial economy as the basis multiobjective programming and genetic algorithm are integrated into the input output analysis several important findings have been gathered in the study 1 the abatement cost varies between 259 97 and 535 46 per ton at different rates of economic growth 2 a reinforced emission abatement target can induce higher macroeconomic costs 3 an inverse u shaped relationship between co2 reduction cost and gdp growth rate was found when gdp growth rate is above the threshold value of 7 marginal abatement costs decrease rapidly in parallel with gdp growth when the gdp growth rate is below 7 the marginal abatement cost increases significantly with economic growth 4 industries that have the highest and least potential of abatement have been identified for effectively reducing co2 emissions beijing needs to promote economic restructuring to maximize the potential of emission abatement and also fulfil the emission abatement target in a cost effective way this paper provides a quantitative approach to rationalize the policy design process of enacting emission targets and recommends cost effective abatement strategies

fiscal spending and green economic growth evidence from china abstract the green economy is considered as an efficient way for sustainability but the connection between fiscal spending and green economic growth has not been systematically explained this paper attempts to fill this research gap based on the panel data of 282 prefecture level cities from 2005 to 2016 we first construct the green economic growth index by using the non radial direction distance function then by employing the system gmm estimation we further evaluate the effect of fiscal education spending and r d spending on green economic growth finally we explore the potential mechanism and discuss our findings we obtain the following conclusions 1 the green economic growth index fluctuated in the study period we attribute it to the political tournament of local governments 2 the system gmm estimation results confirm the existence of composition effect and technique effect in the full sample but the sub sample analysis suggests that there is a heterogeneous effect in different areas with different resources abundant degree 3 mechanism analysis illustrates that fiscal r d spending and education spending foster the green economic growth through technological activities and human capital intensive activities respectively but they exhibit distinct roles in different areas based on these findings we propose some targeted policy suggestions for promoting green economic growth

energy embodied in the international trade of china an energy input output analysis abstract growing international trade has not only positively affected the people s republic of china s china s economic development but also expanded the exportation of energy embodied in goods during their production this energy flow out will pose risks to china s rational utilization of natural resources as well as environmental protection in this paper we evaluate the energy embodied in goods produced in china during 1992 2005 and use input output structural decomposition analysis to identify five key factors causing the changes of energy embodied in exports direct primary energy efficiency primary energy consumption structure structure of intermediate inputs structure of exports and scale of exports for the three sub periods of 1992 1997 1997 2002 and 2002 2005 results show that china is a net exporter of energy and the energy embodied in exports tends to increase over time the expanding total volume of exports and increasing exports of energy intensive goods tend to enlarge the energy embodied in exports within all three sub periods but these driving forces were offset by a considerable improvement of energy efficiency and changes in primary energy consumption structure from 1992 to 2002 and the effects of structure of intermediate input only in the sub period from 1992 to 1997 from 2002 to 2005 the sharp augmentation of energy embodied in exports was driven by all the five factors our research has practical implications for the chinese economy results of this study suggest that the energy embodied in trade should receive special attentions in energy policies design to limit the energy resource out flow and pollution generation

impacts of climate change on self sufficiency of rice in china a cge model based evidence with alternative regional feedback mechanisms abstract climate change would pose a direct and severe challenge to china s rice production and self sufficiency here we use global trade analysis project gtap model to evaluate the impacts of climate change on the self sufficiency of rice in china due to 2 c rise in temperature and further analyze the impact and transmission mechanisms of climate change through market and trade our simulation method switches different regional mechanisms in the gtap model by employing alternative closures and scenarios our results suggest that the fluctuation in rice price is much larger than that of rice production the active regional feedback mechanism has much larger effects than the passive one in assessing climate change impacts with the passive regional feedback mechanism single regional general equilibrium srge and multi regional general equilibrium with china s shock mrge c china s rice export would decrease by more than 8 and import would increase by over 5 which leads to a decrease in rice self sufficiency by more than 0 06 percentage points with the active regional feedback mechanism multi regional general equilibrium with global shock mrge w climate change will increase china s rice export by 2 7 as rising rice exports to south korea overweight the export decrease to other countries concurrently china s rice import would decrease by 0 04 which leads to a slight increase in rice self sufficiency as a whole climate change will not severely threaten china s rice self sufficiency by the decomposition analysis climate change impacts on china s rice self sufficiency mainly depend on the changes in china s domestic rice production interestingly the source of china s rice import will switch from vietnam to pakistan under mrge w which derives from the input structure of paddy rice and rice sectors in different countries

a neglected aspect of the housing market the caretakers of peri urban accra ghana in housing markets in sub saharan africa construction is predominantly undertaken by individuals rather than by the state or private companies due to lack of housing finance the construction process takes many years hence owners often engage live in caretakers to protect their property based on fieldwork conducted in peri urban accra this paper explores why the demand for caretakers arises why there is a supply of caretakers who the caretakers are and their living conditions although life as a caretaker is far from ideal the demand for and supply of caretakers are likely to continue for the foreseeable future caretaking is a form of housing tenancy which is overlooked in housing and labour laws and practices and hence demands more attention from both researchers and policy makers

energy and resource allocation a dynamic model of the dutch disease it is well known that a domestic resource discovery gives rise to wealth effects that cause a squeeze of the tradeable good sector of an open economy the decline of the manufacturing sector following an energy discovery has been termed the dutch disease and has been investigated in many recent studies our model extends the principally static analyses to date by allowing for 1 short run capital specificity and long run capital mobility 2 international capital flows and 3 far sighted intertemporal optimizing behaviour by households and firms the model is solved by numerical simulation

carbon footprint of a university in a multiregional model the case of the university of castilla la mancha abstract the increasing concern about the environmental performance and sustainability of firms and organizations also involves educational institutions if universities aim to become leaders in sustainability aspects they must adopt strategies that involve the entire university system as a useful tool for this purpose the objective of this study was to calculate the carbon footprint for the university of castilla la mancha for the period 2005 2013 the calculation of the university carbon footprint was accomplished through a hybrid environmentally extended input output model in a multiregional framework which constitutes a novelty of the analysis the proposed tool also allows the calculation of the potential for emissions reduction of abatement measures the carbon footprint induced by the consumption of university employees wages is also undertaken as a way to increase awareness and university outreach to society the results show the relevance of both imports and indirect emissions and highlight the significance of energy related emissions enabled by sectors such as renting electrical and optical equipment manufacturing or even services

the contribution of foreign direct investment to clean energy use carbon emissions and economic growth the paper investigates the contributions of foreign direct investment fdi net inflows to clean energy use carbon emissions and economic growth the paper employs cointegration tests to examine a long run equilibrium relationship among the variables and fixed effects models to examine the magnitude of fdi contributions to the other variables the paper analyzes panel data of 19 nations of the g20 from 1971 to 2009 the test results indicate that fdi has played an important role in economic growth for the g20 whereas it limits its impact on an increase in co2 emissions in the economies the research finds no compelling evidence of fdi link with clean energy use given the results the paper discusses fdi s potential role in achieving green growth goals

an empirical investigation of international asset pricing we investigate several asset pricing models in an international setting we use data on a large number of assets traded in the united states japan the united kingdom and france the models together with the hypothesis of capital market integration imply testable restrictions on multivariate regressions relating asset returns to various benchmark portfolios we find that multifactor models tend to outperform single index models in both domestic and international forms especially in their ability to explain seasonality in asset returns we also find that the behavior of the models is affected by changes in the regulatory environment in international markets

measurement of market integration and arbitrage we develop a measurement theory of market integration based on two notions of integrated markets first two markets cannot be perfectly integrated in any sense if one can construct two portfolios one from each market that have identical payoffs but different prices in that case the law of one price is violated across the markets second they cannot be integrated in a stronger sense if there are cross market arbitrage opportunities two measures of market integration are developed respectively reflecting these notions the smaller the measures the more closely integrated in the respective senses the markets among other things they are interpreted as measuring pricing discrepancy between markets article published by oxford university press on behalf of the society for financial studies in its journal the review of financial studies

you either pay more advance rent or you move out landlords ladies and tenants dilemmas in the low income housing market in accra ghana policy makers world wide are concerned about severe housing problems experienced in cities of the developing world this paper examines the rental housing situation in accra ghana it presents findings of a qualitative investigation of the experiences of property owners n 21 and tenants n 23 in an informal private housing market that caters to the housing needs of an expanding section of accra residents but lacks an institutional framework for regulating landlord lady tenant relations the specific focus of the investigation is on perceptions of an intensifying tenancy management practice called the advance rent system overall the findings reveal severe rental housing pressures and conflicting relations between renters and property owners rooted in asymmetrical perceptions regarding this system the paper describes the conditions that shape landlords ladies behaviours towards renters and their reactions to what are generally perceived as fraudulent tenure terms that property owners arbitrarily

the high price of dematerialization a dynamic panel data analysis of material use and economic recession abstract dematerialization at the national level occurs almost exclusively during periods of economic recession or low growth while recession is not a sustainable strategy to curb environmental impact such periods may offer important insights on the possibilities of reducing material use economic recession research has focused on the interactions between macroeconomic and financial variables with little systematic research dedicated to uncovering how resource use develops during periods of recession using a dynamic panel model we investigate whether and to what extent material use in a sample of 150 economies between 1970 and 2010 was affected by recession and low growth recession occurred most frequently and in more than two thirds of all countries during the 1980s and the 1990s in the 2000s more than half of the recessions occurred during the financial crisis of 2008 periods of recession were significantly and negatively correlated with material use they tended to coincide with dematerialization material use decreased in recession years but the significant correlations with growth in material use became weaker as growth rates increased construction minerals and metals used to build stocks of manufactured capital reacted more strongly to economic fluctuations than the throughput dominated flows of biomass and fossil fuels we conclude that the systematic link between recession and dematerialization can become policy relevant if the mechanisms causing reductions in material use during these periods are identified

technological progress and sustainable development what about the rebound effect abstract sustainability concepts that rest on the idea of resource or energy efficiency improvements due to technological progress tend to overestimate the potential saving effects because they frequently ignore the behavioral responses evoked by technological improvements efficiency improvements also affect the demand for resources and energy and often an increase in efficiency by 1 will cause a reduction in resource use that is far below 1 or sometimes it can even cause an increase in resource use this phenomenon is commonly labeled the rebound effect which is well known among energy economists but never attracted much attention in ecological economics the paper starts with the traditional neoclassical analysis of the rebound effect in a partial equilibrium framework that concentrates on the demand of one particular energy service such as mobility or room temperature it also provides an overview of some of the main empirical studies based on this model that mostly confirm the existence of the rebound effect but are controversial about its actual importance however we have to go beyond the neoclassical single service model in order to take care of the variety of possible feedback affecting energy use the paper presents two important expansions of the single service model in order to show the potential relevance of the rebound effect to ecological economics first it is shown that in a multi services model it proves to be difficult to make general statements about the relevance of the rebound effect in this case the overall effect of an increase in energy efficiency on total energy use depends on the on the assumptions about the substitutability between the services considered and the direction of the income effect second the paper also tries to take care of the fact that changes in resource use or energy use are frequently just side effects of other forms of technological progress especially technological change of a time saving nature can have a large influence on energy use as many time saving devices for example faster modes of transport require an increase in energy consumption that is frequently reinforced by a rebound effect with respect to time this effect will be especially strong when wages are high and at the same time energy prices are low as is currently the case in most industrialized countries consequently the paper also provides a strong argument for the introduction of energy taxes

an econometric and cultural analysis of rent control in kumasi ghana an empirical analysis of rent control in kumasi ghana is presented based upon a consumer demand model for housing controlled rent to income ratios are exceptionally low for a developing country moreover the asante housing market exhibits unusual cultural attributes and problems in estimating the without rent control situation benefits and costs of rent control are presented by housing types and income levels and distributional impacts assessed

does increasing investment in research and development promote economic growth decoupling from carbon emission growth an empirical analysis of brics countries abstract it is generally recognized that increasing research and development investment is an effective measure to promote economic and social progress an open question is if increasing research and development investment help economic growth decoupling from carbon emission this study investigates research and development investment and carbon emission in brics countries by using the fully modified ordinary least squares for empirical estimation from 1996 to 2014 the results show that every 1 increase in research and development investment carbon emissions will be decreased by 0 8122 for the brics as a whole which indicates increasing research and development investment has a positive impact on decoupling economic growth from environmental pressure for individual this impact is most significant in china weak in russia and india however it also should be noted that only increasing research and development investment cannot achieve the decoupling between economic growth and carbon emission because other factors such as economic activity industrialization and urbanization renewable energy also influences the decoupling economic growth from carbon emission the results also show that economic activity industrialization and urbanization pose negative impact on the decoupling whereas renewable energy consumption promote the decoupling

technological innovation and green growth in the organization for economic cooperation and development economies abstract green growth means improving production and demand based emissions through innovation of green technologies for cleaner production and supply chain this study examines the effect of technological innovation on green growth on twenty eight 28 organization for economic cooperation and development oecd economies for the period 2000 to 2014 with data sourced from oecd library statistics and world bank world development indicators the economies were sub grouped into oceania america asia and europe preliminary tests conducted were cross section dependence test im pesaran and shin unit root tests westerlund cointegration confirmed that the variables are cointegrated using stirpat and ipat models the study found transport related technologies has been beneficial to green growth in the oceania sub region oecd asia s technologies for production and processing of goods have been beneficial to green growth climate change technologies in relation to generation and transmission of energy are detrimental to green growth in the oecd economies but its impact is visible in asia and europe sub panels environmental related budget and taxes have been found worthwhile in the pursuit of green growth from the dominant negative coefficient values findings led to the presentation of some important implications which could be useful for policy makers and industries in the pursuit of green growth globally

international arbitrage pricing theory an empirical investigation in this paper we test the arbitrage pricing theory apt in an international setting inter battery factor analysis is used to estimate the international common factors and the chow test is used in testing the validity of the apt our inter battery factor analysis results show that the number of common factors between a pair of countries ranges from one to five and our cross sectional test results lead us to reject the joint hypothesis that the international capital market is integrated and that the apt is internationally valid our results however do not rule out the possibility that the apt holds locally or regionally in segmented capital markets finally the basic results of both the inter battery factor analysis and the cross sectional tests are largely invariant to the nume raire currency chosen numerous authors notably solnik 21 grauer litzenberger and stehle 11 and stulz 24 have derived various versions of the international asset pricing model iapm under alternative views of the structure of international capital markets however only a few serious attempts have been made to test various versions of the iapm these tests are largely inconclusive see solnik 20 and stehle 23 apart from the problem stressed by roll 16 of identifying the world market portfolio previous tests of the iapms suffer from the technical problem of aggregating assets of national investors using different numeraire currencies differences in the numeraire arise from differences in consumption baskets in an environment characterized by exchange rate uncertainty in a fruitful attempt to extend the arbitrage pricing theory apt of ross 18 to an international setting solnik 22 derives an international arbitrage pricing theory which is largely devoid of the aforementioned difficulties and thus more amenable to empirical testing 1 as shown by solnik testability of the apt in an

decoupling analysis of world economic growth and co2 emissions a study comparing developed and developing countries abstract this study discusses decoupling trends in world economic growth and co2 emissions based on decoupling theories the decoupling trends of economic growth and co2 emissions in typical developed and developing countries in 1965 2015 are compared by using an oecd decoupling factor model and tapio elastic analysis tea method and the igtx decoupling model on this basis this study evaluates correlations of these three decoupling models by employing the spearman s rank correlation coefficient the research indicates that owing to the igtx decoupling model being easily affected by other non environmental factors the shorter the research period of interest the more easily the decoupling indices distort while the accuracy of the tea method is not limited by the length of the research period of interest with respect to the overall decoupling trend the research shows that 1 strong decoupling is found in developed countries and slightly increases in the stabilisation thereof the decoupling state in the united kingdom and germany is more stable than that of the united states and france 2 developing countries demonstrate weak decoupling that fluctuates significantly and lacks regularity the stabilisation and optimisation of china in decoupling process are better than those of brazil and india finally according to research conclusions relevant policies and suggestions are proposed in view of energy savings and emissions reduction in developing countries

the role of co2 embodiment in us china trade abstract this study examines the influence of us china trade on national and global emissions of carbon dioxide co2 the three basic questions are as follows 1 what amount of co2 emissions is avoided in the us by importing chinese goods 2 how much are co2 emissions in china increased as a result of the production of goods for export to the us and 3 what are the impacts of us china trade on global co2 emissions our initial findings reveal that during 1997 2003 1 us co2 emissions would have increased from 3 to 6 if the goods imported from china had been produced in the us 2 about 7 14 of china s current co2 emissions were a result of producing exports for us consumers and 3 us china trade has increased global co2 emissions by an estimated 720 million metric tons we suggest that the export of us technologies and expertise related to clean production and energy efficiency to china could be a win win strategy for both countries for reducing their trade imbalance and mitigating global co2 emissions improved international accounting methodologies for assigning responsibility for co2 emissions must be designed to account for the dynamic nature of international trade

decoupling global environmental pressure and economic growth scenarios for energy use materials use and carbon emissions in recent decades economic growth and increased human wellbeing around the globe have come at the cost of fast growing natural resource use including materials and energy and carbon emissions leading to converging pressures of declining resource security rising and increasingly volatile natural resource prices and climate change we ask whether well designed policies can reduce global material and energy use and carbon emissions with only minimal impacts on improvements in living standards we use a novel approach of combined economic and environmental modelling to assess the potential for decoupling for 13 world regions and globally we apply a production territorial and consumption approach to discuss regional differences in natural resource use and carbon emissions across three stylized policy outlooks a reference case with no significant changes to environment and climate policies a high efficiency outlook involving a global carbon price rising from 50 to 236 constant price per tonne of co2 between 2010 and 2050 and improvements in resource efficiency rising from 1 5 historically to between 3 5 and 4 5 in the scenarios and a medium efficiency outlook midway between the no change and high outlooks we find that global energy use will continue to grow rapidly under all three scenarios from 17 billion tonnes of oil equivalent toe in 2010 to between 30 and 36 billion toe carbon emissions would be considerably lower with a global carbon price less than half the level of the reference case 29 37 billion tonnes of co2 instead of 74 billion tonnes and also material use would grow much more slowly under a carbon price and significant investment to increase resource efficiency 95 instead of 180 billion tonnes of materials we find that oecd economies have significant potential to reduce their material throughput and carbon emissions with little impact on economic growth and that developing economies such as china could expand their economies at much lower environmental cost globally the effects of very strong abatement and resource efficiency policies on economic growth and employment until 2050 are negligible our study suggests that decarbonization and dematerialization are possible with well designed policy settings and would not contradict efforts to raise human wellbeing and standards of living the research demonstrates the usefulness of scenarios for unpacking environmental and economic outcomes of policy alternatives the findings have important implications for future economic opportunities in a highly resource efficient and low carbon global economy to set human development and achieving the sustainable development goals on a more resilient path

consumer side actions in a low carbon economy a dynamic cge analysis for spain abstract in recent decades the need to strengthen efforts to reduce ghg emissions to combat climate change has become a major global concern as reflected in the 2015 paris agreement and the eu climate strategy 2016 in this context eu countries are required to organize their contributions to environmental improvement through national strategies given the potential importance of demand side actions both directly and through their relationship with the productive system as well as the need for a dynamic evolution we assess the dynamic path and medium term environmental impact of certain consumer oriented measures using a dynamic computable general equilibrium cge model specifically we generate scenarios that follow spain s strategies and evaluate the dynamic impact of more efficient technologies on electricity consumption and the use of transport services both in terms of environmental ghg and sox and economic effects our results confirm the role of technology improvements in delivering positive results for the environment and the importance of economy wide rebound effects through a detailed study of energy uses as a result of efficiency improvements in household energy consumption our findings show that reductions in emissions per person are consistent with economic growth

value based trading of real assets in shipping under stochastic freight rates the article uses a real options valuation model with stochastic freight rates to investigate market efficiency and the economics of switching between the dry bulk and the tanker markets in international shipping a dry bulk carrier is replaced with a tanker when the expected net present value of such a switch is optimal from a real options based decision rule depending on the development of the markets a reversal may take place later the cost and demand parameters upon which the decisions to switch are made including the stochastic characteristics of freight rates are estimated from an empirical analysis that is updated every week throughout a 12 year time period from 1993 to 2005 the second hand market for bulk ships seems to have been efficient most of these years in the sense that market switching usually did not pay off with one major exception it seemed profitable in expectation to leave the dry bulk market and enter the tanker market over a significant period of time shortly after the millenn

the causal relationship between renewable electricity generation and gdp growth a study of energy sources abstract this paper examines the causal relationship between economic growth and electricity generation from renewable sources biomass geothermal hydroelectric solar waste and wind across 20 oecd countries over 1990 to 2008 the results from a commonly used panel error correction model find a a bidirectional relationship between aggregate renewable generation and real gdp b biomass hydroelectricity waste and wind energy exhibit a positive long run relationship with gdp c hydroelectricity and waste generation exhibit a short run positive bidirectional relationship with gdp growth and d biomass hydroelectric and waste electricity generation have the largest impact on real gdp in the long run we extend the analysis to consider the possibility of structural breaks and cross sectional dependence accounting for cross sectional dependence we find that in the short run increases in biomass and waste generation negatively affect gdp while aggregate renewable and hydroelectricity increase gdp energy conservation policies will positively impact gdp if the policies cause decreases in biomass or waste energy but increase hydroelectricity and wind energy

does economic recession reduce material use empirical evidence based on 157 economies worldwide abstract the research on economic recession has been more focused on the interactions between macroeconomic and financial variables however whether material use has been affected during the recession period has remained under explored in order to fill up this gap this study investigates the relationship between material use and economic recession as well as other socio economic drivers by using the material flow analysis and the system generalized method of moments for 157 economies worldwide during 1980 2011 results show that economic recession poses significant and negative impact on domestic material consumption at 1 level illustrating its role as a determinant factor on material mitigation by dividing the research sample into extractive and non extractive economies as well as high mid and low income groups we again confirmed the significant negative correlations as expected no significant sign is found between recession and physical trade balance besides other drivers such as population gross domestic production gdp per capita and technological variables also exert marked effects at different situations this research work provides an empirical study on how recession and other factors affect material use at various scenarios which have essential implications for understanding material flow dynamics in different economic cycles

equity returns and integration is europe changing this paper analyses the consequences of the process of financial and economic integration on european equity markets it documents significant changes in fundamentals notably an increased synchronization of macroeconomic activities and a non negligible evolution in pricing with a decrease in the cost of capital and converging equity premiums as to equity returns themselves in the face of what could turn out to be long run upward trends in the correlations among both country and sector returns and a narrowing of the superiority of country factors the benefits to be gained from finding diversification opportunities at a more disaggregated level appear to be higher than ever copyright 2004 oxford university press

the physical dimension of international trade part 1 direct global flows between 1962 and 2005 abstract the physical dimension of international trade is attaining increased importance this article describes a method to calculate complete physical trade flows for all countries which report their trade to the un the method is based on the un comtrade database and it was used to calculate world wide physical trade flows for all reporting countries in nine selected years between 1962 and 2005 the results show increasing global trade with global direct material trade flows reaching about 10 billion tonnes in 2005 corresponding to a physical trade volume of about 20 billion tonnes adding both total imports and total exports the share from european countries is declining mainly in favour of asian countries the dominant traded commodity in physical units was fossil fuels mainly oil physical trade balances were used to identify the dominant resource suppliers and demanders australia was the principal resource supplier over the period with a diverse material export structure it was followed by mainly oil exporting countries with varying volumes as regards to regions latin america south east asian islands and central asia were big resource exporters mostly with increasing absolute amounts of net exports the largest net importers were japan the united states and single european countries emerging countries like the asian tigers with major industrial productive sectors are growing net importers some of them to an even higher degree than european countries altogether with the major exception of australia and canada industrialized countries are net importers and developing countries and transition countries are net exporters but there are important differences within these groups

multi region input output analysis of co2 emissions embodied in trade the feedback effects energy related co2 emissions embodied in international trade have been widely studied by researchers using the environmental input output framework despite the increasing interest in using the multi regional input output mrio model by researchers few studies have looked into the mechanism of feedback effects we introduce a method called the stepwise distribution of emissions embodied in trade swd eet to reveal how the emissions embodied in trade are absorbed by a country s final demands through a series of allocation steps a country s indirect absorption patterns and its indirect trade balance of emissions from bilateral trade with other countries are also studied based on the proposed method an empirical study using the data of asian economies shows significant differences in the consumption based emission estimates for some economies due to feedback effects through international trade the differences can be largely captured by the first step or the first two steps of the adjustment procedure in the swd eet analysis other findings and some recommendations are also presented

the multi factor energy input output model abstract energy input output analysis eio analysis is a noteworthy tool for the analysis of the role of energy in the economy however it has relied on models that provide a limited description of energy flows in the economic system and do not allow an adequate analysis of energy efficiency this paper introduces a novel energy input output model the multi factor energy input output model mf eio model which is obtained from a partitioning of a hybrid unit input output system of the economy this model improves on current models by describing the energy flows according to the processes of energy conversion and the levels of energy use in the economy it characterizes the vector of total energy output as a function of seven factors two energy efficiency indicators two characteristics of end use energy consumption and three economic features of the rest of the economy moreover it is consistent with the standard model for eio analysis i e the hybrid unit model this paper also introduces an approximate version of the mf eio model which is equivalent to the former under equal energy prices for industries and final consumers but requires less data processing the latter is composed by two linked models a model of the energy sector in physical units and a model of the rest of the economy in monetary units in conclusion the proposed modelling framework improves eio analysis and extends eio applications to the accounting for energy efficiency of the economy

emissions embodied in chinese exports taking into account the special export structure of china abstract quantification of co 2 emissions embodied in china s trade is important for an informed debate on whom to blame for the recent rise in chinese emissions or the calculation of border carbon adjustments applying input output io techniques we calculate these emissions in 1 a standard model 2 a regionally disaggregated model taking into account that export production is concentrated in more advanced and more emission efficient provinces and 3 in a model with export processing taking into account that almost half of the chinese exports rely on a large share of imported intermediates and little domestic value and emissions added we compare year 2007 emissions embodied in chinese exports in a unified framework we also report emissions embodied in chinese imports used for intermediate production of exports by combining calculations for china with data from global io models we find that both a model with 30 provinces 1730 mt co 2 and a model accounting for export processing 1630 mt yield lower chinese emissions embodied in exports compared to the standard model 1782 mt in the regional model emissions are even lower 1522 mt if interprovincial trade is not taken into account

embodied carbon in china s foreign trade an online sci e and ssci based literature review abstract this paper systematically presents a survey of the empirical literature studying the embodied co2 emissions in china s foreign trade ecct based on the bibliometric method and the online version of science citation index expanded sci e and social sciences citation index ssci this study summarizes the latest publications regarding ecct in peer reviewed journals in terms of quantities most productive countries institutions authors citations and disciplines by using synthetic analysis of keyword frequency this study reveals the most popular methodologies applied in measuring ecct discusses the variation of numerical results in the literature and reasons and countermeasures for the results uncertainties continuous investigation of the literature releases the methodology employed for measuring ecct becoming more reasonable and the results more critical however the numerical results of ecct are of great discrepancies within given year by different considerations on methodology specification accounting principles and data sources and processing for instance the estimates of co2 embodied in china s exports changed from 478 mt to over 3000 mt and those of in china s imports ranged from 140 mt to over 1700 mt in 2007 therefore overcoming data inherent limitations and reducing discrepancies among available databases should be urgently considered the results imply that the prospective research tendencies on ecct are to 1 improve china s regional input output data and energy intensity data to more precise estimates under global perspective 2 estimate china s carbon emission at firm level by different firm ownerships in production and consumption worldwide 3 assess china s carbon emission from processing or non processing trade by compiling more detailed multi regional input output table 4 evaluate city level carbon mitigation capacity in china under global mrio model 5 explore new carbon management experience in china s carbon trading market and new trade expansion policy of one belt and one road in her new growth era

pathways to a resource efficient and low carbon europe abstract various environmental footprint concepts have already been developed and applied in sustainability research however these analyses tend to remain restricted to historical observation samples at least in comparison with related research activities in other environmental policy domains like e g climate policy it seems that applications of integrated assessment tools represent rather seldom exceptions within the resource policy domain our paper is therefore intended to strengthen the related evidence base we present recent projections from the dynamic multi region input output mrio simulation model ginfors global inter industry forecasting system which provide an outlook on global development trends until the year 2050 our detailed material footprint and climate policy assessment indicates that a global agreement on a policy mix will allow a clear turnaround towards climate protection and a sustainable use of natural resources without deteriorating economic performance if the eu decides unilaterally to lead the way then this turnaround could also be achieved for the eu while the eu would also benefit economically from this pioneering role a third pathway towards a resource efficient and low carbon europe quantifies the environmental and economic impacts of a strong transitional change induced by european citizens commitments to far reaching sufficiency objectives

is decoupling economic growth from fuel consumption possible in developing countries a comparison of china and india abstract a better understanding the coupling decoupling of economic growth from energy demand in china and india can serve both countries and other developing countries to achieve the goal of gaining higher economic growth with less energy demand to demonstrate the relationship between coupling decoupling economy and energy in china and india better this work has made following contributions i analyzes the decoupling elasticity between economic growth and energy consumption by using the tapio model ii explores the five key effects labor input investment energy structure energy intensity technology level of decoupling elasticity by combining the cobb douglas c d function and log mean divisia index lmdi method and iii evaluates the decoupling efforts by applying decoupling efforts model in china and india between 1990 and 2015 the decoupling elasticity results show china s decoupling elasticity curve is in an inverted u shaped trend and the decoupling elastic value is concentrated between 0 and 0 8 in most years showing a weak decoupling state furthermore the decoupling state is strong decoupling during 2014 2015 indicating china has initially achieved the decoupling of economy and energy consumption while india s decoupling elasticity presents irregular fluctuations indicating that india s decoupling status is not very satisfactory the decomposition results uncover that major effects of decoupling in china and india are similar i e the investment effect is the biggest driver which contributed to a cumulative increasing impact in energy consumption in china and india by 3017 10 million tonnes oil equivalent and 675 18 million tonnes oil equivalent respectively whereas the energy intensity effect is the greatest inhibiting factor which contributed to a cumulative reduction in energy consumption in china and india by 1437 81 million tonnes oil equivalent and 139 21 million tonnes oil equivalent the decoupling efforts results show decoupling effort in china is better than that in india improving energy efficiency is the leading contributor to china s decoupling efforts while advancing technology is the major contributor to india s decoupling effort

eco efficiency assessment of eu manufacturing sectors combining input output tables and data envelopment analysis following production and consumption based accounting approaches abstract assessing the footprint of anthropogenic activities has become particularly challenging in today s globalized markets where a large number of economic transactions taking place across the globe need to be disentangled before the most critical sectors are identified in this work we present an approach to quantify the eco efficiency of economic activities that combines multi regional environmentally extended input output tables and data envelopment analysis we employ this method to assess the european union manufacturing sectors in terms of three inputs global warming potential potential acidifying equivalent and tropospheric ozone forming potential and one output economic wealth following both production and consumption based accounting approaches our approach classifies economic sectors as efficient and inefficient and for the latter it provides improvement targets that if attained would make them efficient we find that there is a significant mismatch at the sectorial level between both accounting schemes each providing complementary information for policy making in the production based case targets allow identifying sectors and pollutants requiring more stringent regulations and or higher investments in cleaner technologies conversely the consumption based accounting allows identifying the ultimate sources of impact an insight that can assist in the selection of alternative cleaner suppliers via eco labelling of products services and proper taxation schemes

carbon footprint scenarios for renewable electricity in australia abstract despite considerable mitigation efforts global emissions from the electricity sector continued to grow in recent years in australia the electricity sector is the largest co 2 emitting industry contributing 35 of the country s total greenhouse gas emissions the australian government targets an 80 reduction of greenhouse gas emissions by 2050 relative to 2010 with a large variety and quantity of renewable energy resources it is technically feasible and seems indispensable that australia s electricity sector be largely decarbonised by 2050 in order to achieve this target in this paper scenario based hybrid life cycle assessment is applied to calculate the economy wide carbon footprints of seven electricity generation technologies in scenarios with differing renewable electricity penetration this work is the first to apply a full life cycle approach to scenario analysis of electricity generation in australia the findings are at the higher end of previously reported carbon footprint intensity ranges and above median values however even when taking into account indirect emissions along the technologies life cycles the results indicate that the employment of different renewable energy technologies can potentially save a considerable fraction of australia s greenhouse gas emissions this makes renewables an essential option for climate change mitigation

input output analysis of co2 emissions embodied in trade and the driving forces processing and normal exports in recent years energy related co2 emissions embodied in international trade and the driving forces have been widely studied by researchers using the environmental input output framework most previous studies however do not differentiate different input structures in manufacturing processing exports and normal exports using china as an example this paper exemplifies how implications of results obtained using different export assumptions differ the study posits that the utilization of traditional i o model results in an overestimation of emissions embodied in processing exports and an underestimation in normal exports the estimate of co2 emissions embodied in china s exports drops by 32 when the extended i o model is used the choice of export assumption has more impact on the decomposition results for processing exports the study further highlights that for a country with an export structure similar to china it is meaningful to look into the impact of export assumption in embodied emission studies

integration vs segmentation in the canadian stock market this paper examines the issue of integration versus segmentation of the canadian equity market relative to a global north american market we compare the international and domestic versions of the capm and find that integration or the mean variance efficiency of the global market index is rejected by the data segmentation is the preferred model based on a maximum likelihood procedure correcting for thin trading we further divide the sample into securities that are interlisted in canada and the u s and those that are not integration is rejected for both groups which indicates that the source of segmentation can be traced to legal barriers based on the nationality of issuing firms empirical studies of international capital markets have left the issue of segmentation versus integration largely unresolved yet the question of national or international pricing of assets has crucial implications for financial decisions if national stock markets are segmented then international portfolios should display superior risk adjusted performance because some of the priced domestic systematic risk is diversifiable also with segmentation many irrelevance propositions for corporate financial strategy break down home firms face optimal hedging decisions as well as optimal foreign versus home borrowing decisions finally criteria for capital budgeting decisions will be quite different under national and international pricing the purpose of this paper is to shed some light on this integration versus segmentation question for the canadian equity market vis a vis a global north american market in this paper integration is defined2 as a situation where investors earn the same risk adjusted expected return on similar financial instruments in different national markets the key problem of course is the pricing

decoupling analysis and environmental kuznets curve modelling of provincial level co2 emissions and economic growth in china a case study abstract guangdong is one of the most representative provinces of china in terms of reflecting how the provincial level co2 emissions dynamically evolve with economic development during the process of industrialisation and urbanisation the present study combines decoupling analysis with environmental kuznets curve ekc modelling to systematically explore the interactions between co2 emissions and economic growth in guangdong from the short to long terms aiming to provide the referential significance of low carbon development to other chinese provinces empirical results indicate that co2 economy interactions in guangdong dynamically changed with time performing an effect of expansive weak decoupling during 1995 2014 and having a potential to achieve a strong decoupling in the long run the decoupling states of various sectors and their contributions to the provincial overall decoupling differed greatly and varied by time and household and service sectors played increasingly important roles overall the decoupling effect of provincial co2 emissions is distinctly affected by the stage of industrialisation and urbanisation renewable energy utilisation as well as low carbon technical progress therefore promoting co2 economy decoupling at the provincial level should be specific to the feature and development reality of various provinces

long term global market correlations the correlation structure of the world equity markets varied considerably over the past 150 years and was high during periods of economic integration we decompose diversification benefits into two parts one component due to variation in the average correlation across markets and a another component due to the variation in the investment opportunity set from this we infer that periods of globalization have both benefits and drawbacks for international investors globalization expands the opportunity set but as a result the benefits from diversification rely increasingly on investment in emerging markets

economic energy and greenhouse emissions impacts of some consumer choice technology and government outlay options abstract the impacts of selected spending options in the australian economy are determined in terms of energy consumption greenhouse gas emissions and a range of economic parameters six case studies of one current practice and one alternative environmentally motivated spending option are carried out describing consumer choices technologies and government outlays the assessment method is based on input output theory and as such enables both the direct and indirect effects of spending to be quantified in general the results indicate that pro environmental objectives such as reductions in energy consumption and greenhouse gas emissions are compatible with broad socio economic benefits such as increases in employment and income and reductions in imports

assessing global resource use and greenhouse emissions to 2050 with ambitious resource efficiency and climate mitigation policies achieving sustainable development requires the decoupling of natural resource use and environmental pressures from economic growth and improvements in living standards g7 leaders and others have called for improved resource efficiency along with inclusive economic growth and deep cuts in global greenhouse emissions however the outlooks for and interactions between global natural resource use resource efficiency economic growth and greenhouse emissions are not well understood we use a novel multi regional modeling framework to develop projections to 2050 under existing trends and three policy scenarios we find that resource efficiency could provide pro growth pro environment policies with global benefits of usd 2 4 trillion in 2050 and ease the politics of shifting towards sustainability under existing trends resource extraction is projected to increase 119 from 2015 to 2050 from 84 to 184 billion tonnes per annum while greenhouse gas emissions increase 41 both driven by the value of global economic activity more than doubling resource efficiency and greenhouse abatement slow the growth of global resource extraction so that in 2050 it is up to 28 lower than in existing trends resource efficiency reduces greenhouse gas emissions by 15 20 in 2050 with global emissions falling to 63 below 2015 levels when combined with a 2 c emissions pathway in contrast to greenhouse abatement resource efficiency boosts near term economic growth these economic gains more than offset the near term costs of shifting to a 2 c emissions pathway resulting in emissions in 2050 well below current levels slower growth in resource extractions and faster economic growth

simulating the impact of new industries on the economy the case of biorefining in australia abstract we investigate the economic and employment consequences of introducing a new sugarcane based biofuel industry into australia we model the new biofuel industry on the production recipe of the existing large scale gasoalcohol and alcohol sectors in the brazilian economy to this end we utilise a hybrid io lca input output life cycle assessment approach which involves inserting data on new processes and or sectors into an existing io table in particular we develop and test an analytical and a numerical approach for re balancing an io table augmented with rows and columns representing large new biofuel industries we quantify changes in economic output and employment in the australian economy we conclude that a future biofuel industry will be employment positive for australia

input output analysis of co2 emissions embodied in trade the effects of sector aggregation abstract energy related co2 emissions embodied in international trade have been widely studied by researchers using the environmental input output analysis framework it is well known that both sector aggregation and spatial aggregation affect the results obtained in such studies with regard to the latter past studies are often conducted at the national level irrespective of country or economy size for a large economy with the needed data studies may be conducted at different levels of spatial aggregation we examine this problem analytically by extending the work of su et al su b huang h c ang b w zhou p 2010 input output analysis of co2 emissions embodied in trade the effects of sector aggregation energy economics 32 1 166 175 on sector aggregation we present a numerical example using the data of china and by dividing the country into eight regions it is found that the results are highly dependent on spatial aggregation our study shows that for a large country like china it is meaningful to look into the effect of spatial aggregation

hidden linkages between resources and economy a beyond gdp approach using alternative welfare indicators taking gdp as the standard economic indicator for economic welfare recent resources economy studies indicate the dematerialization of the economy the so called decoupling effect this conclusion seems to alleviate concerns over resource scarcity and limits to growth and feeds optimism for green growth and sustainability prospects however the validity of gdp as the sole and unambiguous measure of the ultimate outcome of the economy has been severely disputed there is nowadays increasing interest in broader welfare measurements that capture more aspects of economic output and hence constitute better approximations of well being the present paper provides an overview of the above discussion and sets out to explore the relevance of three alternative welfare indicators the human development index hdi the index of sustainable economic welfare isew and the genuine progress indicator gpi as a basis for evaluating the dependency of welfare and its major engine the economy on natural resources increasing welfare appears to require a disproportionate use of resources strong and increasing dependency on resources at the global level and in giant countries such as china and india may have serious implications for current sustainability policies and the united nations sustainable development goals

multiplicative structural decomposition analysis of aggregate embodied energy and emission intensities abstract aggregate intensity indicators such as the ratio of a country s energy and emissions to its gdp are often used by researchers and policymakers to study energy and environmental performance this paper analyzes the relationship between energy or emissions and value added or gdp from a different viewpoint namely from the demand rather than the production perspective using the input output i o framework the aggregate embodied intensity aei defined as the ratio of embodied energy or emissions to embodied value added can be defined at the aggregate final demand category and sectoral levels the total aggregate intensity can be presented as a weighted sum of the aeis at the final demand category or sectoral level changes of the aei at different levels can be decomposed to identify the driving forces using multiplicative sda a study using the latest 2007 and 2012 datasets of china indicates that a its aggregate intensity of co 2 emissions was mainly determined by the aei in investment and b the emission intensity effect generally contributed the most to the aei ratio changes at different levels the proposed framework can be applied to other aggregate intensity indicators and extended to multi country region analysis

consumption based versus production based models of international equity markets abstract this paper compares the ability of two discount rate models to explain the cross sectional and time series variation of stock returns in the us japan the uk germany and canada the data consist of quarterly returns on morgan stanley s capital international indices for the period from january 1972 to march 1993 the two models considered are a consumption capm linking the discount rate to the intertemporal marginal rate of substitution in consumption and a production capm linking the discount rate to the intertemporal marginal rate of transformation in production the main result is that a production based capm performs better than the consumption based capm in explaining national stock market returns the results also indicate that time variation in risk premia rather than time variation in betas provides most of the explanatory power in both models jel f30 g12 1997 elsevier science ltd

what causes inequality in material productivity between countries abstract material productivity mp is a sustainability indicator that measures usage efficiency for raw materials the use of natural resources has grown steeply since the industrial revolution and this growth has even accelerated in recent decades it has thus become critical to monitor the intensity of natural resource usage when producing intermediate or final goods discovering which socio economic variables influence the mp indicator and explain differences between economic units is nowadays a key issue on average mp has increased over the past two decades but at the same time so has disparity between countries this paper s contribution consists in discovering the explanatory variables for both these phenomena in order to achieve that aim a regression based inequality decomposition rbid methodology is used the original fields rbid model has been transformed into a logarithmic model which allows us to directly obtain the elasticity of mp to changes in its drivers the sample we use is broadly representative of the worldwide situation in the years 1990 2010 our main results are that in terms of explaining inequalities and changes in mp the agricultural share of gdp is the most relevant explanatory variable and that this is followed by affluence the explanatory powers of population density and trade openness are perhaps surprisingly of much lower importance the results are useful not only in academic terms but also for policy guidance

capital controls and international capital market segmentation the evidence from the japanese and american stock markets the paper focuses on two countries japan and the u s to test the integration of capital markets in japan the enactment of the foreign exchange and foreign trade control law in december of 1980 amounted to a true regime switch that virtually eliminated capital controls using multifactor asset pricing models we show that the price of risk in the u s and japanese stock markets was different before but not after the liberalization this evidence supports the view that governments are the source of international capital market segmentation the notion that world capital markets are perfectly integrated is central to most theoretical developments in both international finance and macroeconomics indeed it also lies behind much of the recent international policy discussion capital markets are integrated if assets with perfectly correlated rates of return have the same price regardless of the location in which they are traded 1 segmentation may arise either because of government impediments to capital movements or because of individuals attitudes or irrationality if the hypothesis that the international capital markets are integrated is rejected there is still an important empirical question left unanswered which is related to the source of segmentation while there is a rich body of theoretical research on international market integration only a few studies have tried to investigate this important question empirically a first group of empirical studies on market integration has generally adopted

financial integration a new methodology and an illustration this paper develops a simple methodology to test for asset integration and applies it within and between american stock markets our technique relies on estimating and comparing expected risk free rates across assets expected risk free rates are allowed to vary freely over time constrained only by the fact that they must be equal across risk adjusted assets in well integrated markets assets are allowed to have standard risk characteristics and are constrained by the fama and french factor model of covariances over short time periods we find that internal integration in the s p 500 market is never rejected and is not generally rejected in the nasdaq integration between the nasdaq and the s p however is always rejected dramatically jel g14

sustainable de growth mapping the context criticisms and future prospects of an emergent paradigm article i nfo sustainable de growth is both a concept and a social grassroots northern movement with its origins in the fieldsofecologicaleconomics socialecology economicanthropologyand environmentalandsocialactivistgroups this paper introduces the concept of sustainable de growth by mapping some of the main intellectual influences fromthese fields with special focus on the francophone and anglophone thinking about this emergent notion we propose hypotheses pertaining to the appeal of sustainable de growth and compare it to the messages enclosed within the dominant sustainable development idea we scrutinize the theses contradictions and consequences of sustainable de growth thinking as it is currently being shaped by a heterogeneous body of literature and as it interacts with an ample and growing corpus of social movements we also discuss possible future paths for the de growth movement compared to the apparent weakening of the sustainable development paradigm

is carbon emission growth decoupled from economic growth in emerging countries new insights from labor and investment effects abstract as emerging countries are both major contributors to global carbon emissions growth and global economic growth the sharp contradiction between economy and carbon emissions has seriously hindered the sustainable development of emerging countries and is not conducive to the realization of global emission reduction targets this work takes brics brazil russia india china and south africa the representatives of emerging countries as an example to investigate the decoupling state between economic growth and carbon emissions and to uncover the driving factors behind these decoupling the results show i russia and south africa have experienced the longest time of strong decoupling indicating that the decoupling in these two countries is better than that in other countries china india and south africa was characterized by expansive coupling weak decoupling and expansive negative decoupling respectively ii the labor effect and investment effect have contributed to the carbon emissions growth in the brics and the reasons for the carbon emissions changes in russia india china and south africa are strongly consistent while brazil has a different performance iii the investment decoupling effect has hindered the decoupling process in russia south africa china and india but has promoted the decoupling process in brazil while the energy intensity effect is the driving force in the decoupling process in most countries finally the policy recommendations for the different decoupling status of each country were put forward

china s carbon emissions embodied in normal and processing exports and their driving forces 2006 2012 abstract this paper constructed a time series extended input output dataset 2006 2012 to analyze china s carbon emissions embodied in both normal and processing exports at a detailed 135 sector level the structural decomposition analysis sda was further applied to shed light on the driving forces behind the changes in their embodied emissions over the entire time period this empirical study confirms the importance of using the extended model for analyzing the trade related embodiment especially for processing exports the embodied emissions in both normal and processing exports first increased from 2006 to 2008 then dropped during the global financial crisis 2008 2009 and then rose again after 2009 the embodied emissions as a percentage of total co2 emissions were quite stable before and after the global financial crisis at around 24 over the 2006 2008 period and 18 over the 2010 2012 period from 2006 to 2012 emission intensity played the key role in reducing the embodied emissions around 595 mt co2 while the total export effect contributed the most to the increase in embodied emissions around 552 mt co2 similar analysis can be applied to other indicators such as energy water ghg emissions pollutants and materials

the sustainable development index measuring the ecological efficiency of human development in the anthropocene abstract when the human development index hdi was introduced in the 1990s it was an important step toward a more sensible measure of progress one defined less by gdp growth and more by social goals but the limitations of hdi have become clear in the 21st century given a growing crisis of climate change and ecological breakdown hdi pays no attention to ecology and retains an emphasis on high levels of income that given strong correlations between income and ecological impact violates sustainability principles the countries that score highest on the hdi also contribute most in per capita terms to climate change and other forms of ecological breakdown in this sense hdi promotes a model of development that is empirically incompatible with ecological stability and impossible to universalize in this paper i propose an alternative index that corrects for these problems the sustainable development index sdi the sdi retains the base formula of the hdi but places a sufficiency threshold on per capita income and divides by two key indicators of ecological impact co2 emissions and material footprint both calculated in per capita consumption based terms and rendered vis a vis planetary boundaries the sdi is an indicator of strong sustainability that measures nations ecological efficiency in delivering human development

intraday market price integration for shares cross listed internationally this study investigates market price integration by testing per share trade execution price or cost tep c differentials for matched intraday trades for a sample of canadian shares cross listed in the u s the tse trade price advantage over the entire time period changed significantly after both the tse s own minimum quotation increment reduction and that of its u s competitors we show that the differential tep c is equivalent to the international effective spread differential and that market quality comparisons which benchmark using the national instead of the international bbo need to compare both national effective half spread and midspread differences our cross sectional regression results support our predictions that tep c differentials can be explained by differences in national midspreads and by ex ante proxies of national effective half spreads the tep c differentials vary inversely with increasing levels of our measure of signed market nonfragmentation

the physical dimension of international trade part 2 indirect global resource flows between 1962 and 2005 global trade is increasingly being challenged by observations of growing burden shifting in particular of environmental problems this paper presents the first worldwide calculations of shifted burden based on material flow indicators in particular direct and indirect physical trade balances this study covers the period between 1962 and 2005 and includes between 82 and 173 countries per year the results show that indirect trade flow volumes have increased to around 41 billion tonnes in 2005 the traded resources with the highest share of associated indirect flows are iron hard coal copper tin and increasingly palm oil regarding the burden balance between regions europe is the biggest shifter whereas australia and latin america are the largest takers of environmental burden due to resource extraction to evaluate the findings from a global perspective the results are analysed in terms of resource flow induced environmental pressure related to a country s land area in terms of total and per capita area resource endowment and population density seem to be more relevant in determining the physical trade balance including indirect flows than income level

foreign direct investment and decoupling between energy and gross domestic product in developing countries on a sample of 20 developing countries we noticed a clear decline in the energy intensity as foreign direct investment increases the reason for that probably is the use of modern technologies that came with foreign direct investment i e a leapfrogging over the old fashioned traditional technologies in use in these countries

input output analysis of co2 emissions embodied in trade competitive versus non competitive imports energy related co2 emissions embodied in international trade have been widely studied by researchers using the environmental input output framework in the literature two different approaches to deal with emissions embodied in a country s imports can be found one of the approaches is based on the assumption of competitive imports while the other is based on the assumption of non competitive imports we show that the implications of the results obtained using different imports assumptions are not the same the approach using the competitive imports assumption gives estimates larger than those obtained using the non competitive import assumption the differences between the two embodiment estimates come from the transition of embodied emissions in china s imports for intermediate consumption to those in china s exports this explains why relatively high estimates of co2 emissions embodied in china s exports are reported in several recent studies appearing in energy policy

china s foreign trade and climate change a case study of co2 emissions abstract the globalization of trade has numerous environmental implications trade creates a mechanism for consumers to shift environmental pollution associated with their consumption to other countries carbon leakage exerts great influences on international trade and economy applying an input output approach the paper estimates the amount of carbon dioxide co2 embodied in china s foreign trade during 1997 2007 it is found that 10 03 26 54 of china s annual co2 emissions are produced during the manufacture of export goods destined for foreign consumers while the co2 emissions embodied in china s imports accounted for only 4 40 1997 and 9 05 2007 of that we also estimate that the rest of world avoided emitting 150 18 mt co2 in 1997 increasing to 593 mt in 2007 as a result of importing goods from china rather than manufacturing the same type and quantity of goods domestically during 1997 2007 the net additional global co2 emissions resulting from china s exports were 4894 mt then the paper divides the trade embodied emissions into scale composition and technical effect it was found that scale and composition effect increased the co2 emissions embodied in trade while the technical effect offset a small part of them finally its mechanism and policy implications are presented

disaggregating energy use cap among china s provinces the 2015 paris climate change negotiations represents the most ambitious worldwide effort to date to combat climate change as the largest energy consumer and carbon emitter china pledges 60 65 cut in carbon intensity below 2005 levels by 2030 to accelerate china s climate efforts china has also committed to cap its primary energy use at 4 8 billion tons of coal equivalent in 2020 this paper proposes an equitable and efficient scheme to disaggregate this national goal among provinces a three step disaggregation procedure is proposed which takes into account the initial allocation national redistribution and inter provincial adjustment first this study allocates the incremental energy quota taking 2010 as the base year second part of the energy quota is set aside by the central government for redistribution purposes while an incremental energy quota index comprising equity and efficiency criteria is used for initial allocation among provinces finally historical efforts and inter provincial energy flows are considered for inter provincial adjustment this disaggregation scheme is flexible and can be easily extended to allocation and management of other resource and environmental targets the empirical findings can assist decision makers in identifying which provinces are likely to over consume the energy quota relative to the proposed allocation and which provinces are likely to perform better in energy conservation moreover the results show that the energy cap set for 2020 is unachievable without further action market based instruments such as an energy allowance trading market are strongly recommended to achieve the energy use target in an equitable and cost effective manner

modelling socio economic and energy data to generate business as usual scenarios for carbon emissions abstract the uk government is legally committed to achieving an 80 reduction in carbon dioxide emissions compared with 1990 by 2050 the use of scenarios is wide ranging to inform policy development and forming a business as usual scenario helps to understand possible effects of different policy interventions however the term business as usual is frequently misused we show how econo physical business as usual scenarios can be developed by examining the historical behaviour of coefficients which manifest the relationship between components of an economy we endogenise economic growth by mimicking national level policies that focus on a target level of unemployment our case study demonstrates the trendability of coefficients which for one example coefficient is replicated for australia colombia taiwan and the usa we manifest a gross domestic product growth of 2 falling to 1 which contrasts with an exogenous growth of 2 3 of a comparator business as usual scenario we suggest that it may be possible to achieve a greater reduction in the business as usual carbon dioxide emissions in the uk fifth carbon budget than currently projected

ossified materialism introduction to the special volume on absolute reductions in materials throughput and emissions drawing from papers in this special volume sv this introductory paper on absolute reductions argues that the magnitude scope and urgency of the sustainability challenge require a drastic change in global civilisation including a radical transformation of the institutional arrangements and socio technical systems that facilitate the pursuit of wellbeing the authors of this paper identify four main challenges to absolute reductions including the resource intensive conventional template for development macroeconomic structures and trade policies creating burden shifting and inequality a resourceefficiency improvements fallacy and the dominant consumerist culture and lifestyles the paper demonstrates

assessing the decoupling of economic growth from environmental impacts in the european union a consumption based approach abstract pursuing a responsible and sustainable development the united nations urged to decouple economic growth from environmental impacts several european union eu policies have been implemented towards such goal although multiple authors have evaluated the decoupling of the economic growth from the resource use or environmental concerns the environmental assessment mostly focused on pressures rather than impacts and used single indicators assumed to be a proxy of the overall effects on the environment furthermore no studies were found using a process based life cycle approach to quantify the environmental impacts of consumption to solve such research gap this paper assesses the decoupling in the eu focusing on potential environmental impacts complementing a production based approach with two options for accounting for the impacts of consumption the aim of this paper is to evaluate the decoupling of the economic growth in terms of gross domestic product from the environmental impacts due to eu 28 consumption assessed by means of life cycle assessment lca the decoupling is then assessed in impact terms rather than limited to pressures by using the environmental footprint ef2017 indicators which allows assessing 16 different impacts the consumption footprint indicator quantified the environmental impacts of eu apparent consumption including the territorial impacts domestic footprint and the embodied impacts in both imports and exports trade footprint the inventory of pressures for the trade component is compiled either with a bottom up approach process based lca of representative traded goods or a top down approach input output based lca methodological aspects influencing the decoupling assessment and the resulting outputs are presented and discussed according to the results the environmental impacts of eu 28 consumption showed decoupling during the last decades 2005 2014 between relative to absolute decoupling depending on the inventory modeling approach taken some countries showed higher decoupling levels than others displaying a heterogeneous map of eu 28 decoupling which was led by acidification particulate matter land use and eutrophication impacts notwithstanding current limitations the assessment of decoupling using consumption based environmental indicators is very promising for supporting policy making towards addressing the actual impacts driven by the eu production and consumption system

green growth planning a multi factor energy input output analysis of the canadian economy abstract incorporating socioeconomic and environmental considerations into energy decisions is necessary when tackling climate change and accelerating green growth in this work we propose a novel extension of the multi factor energy input output model to support evidence informed energy policy making and green growth planning through the introduction of eight different multipliers and two green growth indexes we demonstrate the approach through application at the national scale in canada in particular we quantitatively assess the extent to which changes in final demand impact the domestic and imported primary and renewable energy flows co2 emissions economic expansion and energy job earnings the results point to a potential path of green growth in canada prioritizing activities that generate economic and job growth at minimal environmental pressure i e fewer co2 emissions economic activities that are critical for stimulating green growth in the short to medium run are identified and recommendations are made regarding a longer structural change path for improving the supply chains of other economic activities this work provides insights to decision makers seeking strategies e g policy reforms or targeted public expenditure strategies to accelerate green growth planning on a national scale
