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

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

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

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

sustainable consumption within a sustainable economy beyond green growth and green economies abstract in 1992 one unambiguous result of the unced conference was the need for changing consumption and production patterns with affluent countries taking the lead 20 years later at the 2012 uncsd little is left over and instead the green economy has been the theme pursued by the oecd the eu and other countries so the question needs to be answered if this is finally an attempt to put into practice what was promised 20 years ago or another diversion from what needs to be accomplished sustainable development is still a convincing concept if the original definition is taken avoiding the confusion caused by partisan interests reinterpreting the concept focussing on human needs fulfilment and respecting environmental limits it can still guide strong sustainable consumption green economy green growth on the other hand is a new terminology for what is known since 40 years as ecological modernisation it is indeed overdue but with its focus on efficiency and innovation it cannot guarantee to fulfil the brundtland sustainability criteria a factor analysis based on the i p a t formula demonstrates how optimistic the assumptions regarding future technologies must be to support the green growth concept consequently the authors pledge for a pragmatic risk avoiding approach by slimming the physical size of the economy this requires strong sustainable consumption including production as resource consumption which in turn requires a change of the societies institutional settings formal and informal mechanisms and orientations finally some elements of a strategy towards this end are pointed out with special emphasis on the role of non governmental organisations ngos through networking and advocacy they can both stimulate bottom up action and mobilise the pressure necessary for the institutional changes which are needed to mainstream strong sustainable consumption

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

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

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

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

planning and approximation models for delivery route based services with price sensitive demands abstract classical vehicle routing problems typically do not consider the impact of delivery price on the demand for delivery services existing models seek the minimum sum of tour lengths in order to serve the demands of a given set of customers this paper proposes approximation models to estimate the impacts of price on delivery services when demand for delivery service is price dependent such models can serve as useful tools in the planning phase for delivery service providers and can assist in understanding the economics of delivery services these models seek to maximize profit from delivery service where price determines demand for deliveries as well as the total revenue generated by satisfying demand we consider a variant of the model in which each customer s delivery volume is price sensitive as well as the case in which customer delivery volumes are fixed but the total number of customers who select the delivery service provider is price sensitive a third model variant allows the delivery service provider to select a subset of delivery requests at the offered price in order to maximize profit

recycling recovering and preventing food waste competing solutions for food systems sustainability in the united states and france abstract in recent years a wide range of organizations in developed countries have embarked on efforts to address the economic environmental and social impacts of food waste based on more than 120 interviews and complementary observations in the united states and france this paper examines how recent mobilizations impact the way surplus food is actually managed with respect to sustainable production and consumption this analysis of multiple stakeholders interests and motives complements a growing literature on food waste prevention and management focused on technical evaluations of solutions recent frameworks on food surplus and waste establish one hierarchy of preferable categories of solutions first prevention reducing surplus at the source then recovery reusing for human consumption and finally recycling feeding animals creating energy or compost fieldwork results show that actors with different interests in food commodity chains actually develop competing solutions both within and between three hierarchies based on environmental social and economic goals in the long term the solutions they promote may therefore not achieve win win win benefits for all actors and at all scales drawing on a distinction between weak and strong sustainability this paper argues that strong prevention based on holistic changes in the food system is the most sustainable solution to food surplus and waste it suggests that academics focus on strong food surplus prevention but also that advocates encourage government and corporate actors to differentiate between weak and strong actions to diffuse strong sustainability across organizations and countries

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

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

what happens during recessions crunches and busts we provide a comprehensive empirical characterization of the linkages between key macroeconomic and financial variables around business and financial cycles for 21 oecd countries over the period 1960 2007 in particular we analyse the implications of 122 recessions 113 28 credit contraction crunch episodes 114 28 episodes of house price declines busts 245 61 episodes of equity price declines busts and their various overlaps in these countries over the sample period our results indicate that the interactions between macroeconomic and financial variables can play a major role in determining the severity and duration of a recession specifically we find evidence that recessions associated with credit crunches and house price busts tend to be deeper and longer than other recessions stijn claessens m ayhan kose and marco e terrones

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

global appropriation of resources causes high international material inequality growth is not the solution abstract high levels of resource consumption cause detrimental environmental change very low consumption may fail to meet basic needs a major challenge for a sustainability transformation is to reduce inequalities and achieve a globally sustainable level of resource flows by providing access to resources beyond national boundaries trade could either lead to more equal international distribution or aggravate unequal distribution of material resources for a sample of 173 countries between 1993 and 2010 we studied the role of trade and the upstream global appropriation of resources in international material inequality until the turn of the century per capita material extraction was as unequally distributed as material consumption extraction plus imports minus exports import and export flows as such do not greatly affect inequality the global appropriation of materials associated with trade however decisively increased inequality until 2000 in the 21st century decreasing inequality coincided with a sharp rise in global material extraction appropriated by high and upper middle income countries such growth led reduction of inequality is not environmentally sustainable it has until now been enabled by global trade patterns distributing resources in a way that can never be globally inclusive putting especially the world s poorest countries at risk

material flows and resource productivity in china south korea and japan from 1970 to 2008 a transitional perspective abstract china japan and south korea are the important east asian countries and being paid intensive attentions to their economic miracle while their environmental performance is less discussed together these three countries are in different level of developmental stages from emerging economy to matured developed economy we hereby provide a laboratory idea to investigate the socio economic metabolism under typical development stages so that enlightenment on global resource management policy making can be made this study is based on a long time series data on the material flow analysis on china south korea and japan applied with up to date standardized methodologies of material flow accounting material flows resource productivity data indicators as well as environmental kuznets curve are presented and compared from 1970 to 2008 driving forces for the material flow change were further investigated with ipat approach obvious differences of resource efficiency productivity and consumption patterns were verified japan presented the trend of dematerialization and technology effects made significant contribution china was highlighted with surging resource consumption stage mainly driven by the economic and population factors even though the resource efficiency was significantly enhanced in the past three decades south korea presented the combined features of china and japan in different stages based on the analytical results information and insights behind results like the industrial structure value chain position in the global supply demand chain and how they had impacts on the resource efficiency and productivity were discussed in depth the research results provide critical insights to future effective and efficient global resource management policy making

international comparison of resource use and its relation to economic growth the development of total material requirement direct material inputs and hidden flows and the structure of tmr abstract resource flows constitute the materials basis of the economy at the same time they carry and induce an environmental burden associated with resource extraction and the subsequent material flows and stocks which finally end up as waste and emissions a reduction of this material throughput and the related impacts would require a reduction of resource inputs and breaking the link between resource consumption and economic growth would require an increase in resource productivity material flow analysis mfa can be used to quantify resource flows and indicate resource productivity in this article we study the available empirical evidence on the actual de linkage of material resource use and economic growth we compare resource use with respect to total material requirement tmr and direct material input dmi for 11 and 26 countries respectively and the european union eu 15 the dynamics of tmr as well as of the main components are analysed in relation to economic growth in order to show whether there is a decoupling relative or absolute from gdp and a change of the metabolic structure in the course of economic development dmi cap so far only decoupled from gdp cap in relative terms that is in most countries it reached a rather constant level but with the exception of czech republic showed no absolute decline yet tmr cap was reduced in two high income countries and one low income country due to political influence changes in tmr were more influenced by hidden flows hf than by dmi we analyse the dynamics of the structure and composition of tmr in the course of economic development in general the economic development of industrial countries was accompanied by a shift from domestic to foreign resource extraction different relations can be discovered for the share of biomass fossil fuel resources construction resources and metals and industrial minerals

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

economic lot size model for price dependent demand under quantity and freight discounts abstract previous studies have developed procedures which determine optimal lot size and selling price when demand depends on price and all unit quantity discounts are offered further recent studies have addressed the concepts of quantity and freight discounts for constant demand in this paper we incorporate quantity and freight discounts in inventory decision making when demand rather than being constant is considered to be dependent upon price an algorithm is developed to determine the optimal lot size and selling price for a class of demand functions including constant price elasticity and linear demand a numerical example is provided to illustrate the model and a computer program is developed to implement the model derived in the paper

strong sustainable consumption governance precondition for a degrowth path this paper aims to link two debates and literatures at the cutting edge of sustainable development research and governance sustainable consumption and degrowth interestingly these literatures have only recently started to exchange and integrate insights despite their similar interest in the fundamental systemic challenges to sustainable development the paper argues that this lack of connection is due to a predominance of perspectives in sustainable consumption governance that focus almost exclusively on questions of efficiency gains this weak sustainable consumption governance however is not able to address the challenges to sustainable development arising from overconsumption in general or the rebound effect and distributive issues in particular in contrast a strong sustainable consumption perspective provides a basis for a promising inquiry into the linkages between consumption and sustainable development as well as a fruitful exchange with degrowth specifically it allows the delineation of relevant insights on the role of values in governance obstacles to political reform and promising political strategies for the degrowth debate and literature

linking analyses and environmental kuznets curves for aggregated material flows in the eu abstract the relationship between economy and environmental impacts has been an essential topic in the discussion on environmental problems for a long time from the 1990s this relationship has gained a position in environmental policy as well de coupling the use of natural resources from economic growth has been set as one of the policy goals in the sixth environmental action programme by the european commission in the scientific discussion the concept of environmental kuznets curve deals closely with the de coupling or de linking phenomenon aggregated material flows on the other hand have often been considered as a macro level proxy of environmental degradation different methods or approaches have been designed for sustainability or carrying capacity evaluation as well the objective of this article is i to discuss the possibilities and limitations of using environmental and economic indicators in the sustainability analysis at the macro level ii to present a theoretical framework for the linking analysis including a classification of the degrees of de linking re linking environmental impacts from to economic growth and iii to give an empirical example by using indicators of direct material flows as a proxy of environmental degradation and by applying the framework into the european union and its 15 member countries the results show that the trend in the european union is a weak de linking of material flows from economic growth during the years 1980 2000 in other words material intensity of the economy has generally decreased due to increased efficiency but the absolute amount of material use has increased although at a lower rate of increase than economic growth on the other hand there is a quite large variation between different eu member countries however absolute decrease in the use of materials cannot be found as a continuous trend between the years 1980 and 2000 in any of the studied eu member countries

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

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

uncapacitated plant location under alternative spatial price policies given a spatial system of clients demand functions this paper proposes solution methods to determine the prices the number the locations the sizes and the market areas of the plants supplying the clients in order to maximize the profit of the firm three alternative spatial price policies are considered i uniform mill pricing in which the same price is charged to the clients at the plant door ii uniform delivered pricing in which clients pay the same delivered price irrespective of their locations and iii spatial discriminatory pricing which is such that the firm sets client specific prices based on their locations computational results are reported

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

growth in global materials use gdp and population during the 20th century the growing industrial metabolism is a major driver of global environmental change we present an assessment of the global use of materials since the beginning of the 20th century based on the conceptual and methodological principles of material flow accounting mfa on the grounds of published statistical data data compilations and estimation procedures for material flows not covered by international statistical sources we compiled a quantitative estimate of annual global extraction of biomass fossil energy carriers metal ores industrial minerals and construction minerals for the period 1900 to 2005 this period covers important phases of global industrialisation and economic growth the paper analyses the observed changes in the overall size and composition of global material flows in relation to the global economy population growth and primary energy consumption we show that during the last century global materials use increased 8 fold humanity currently uses almost 60 billion tons gt of materials per year in particular the period after wwii was characterized by rapid physical growth driven by both population and economic growth within this period there was a shift from the dominance of renewable biomass towards mineral materials materials use increased at a slower pace than the global economy but faster than world population as a consequence material intensity i e the amount of materials required per unit of gdp declined while materials use per capita doubled from 4 6 to 10 3 t cap yr the main material groups show different trajectories while biomass use hardly keeps up with population growth the mineral fractions grow at a rapid pace we show that increases in material productivity are mostly due to the slow growth of biomass use while they are much less pronounced for the mineral fractions so far there is no evidence that growth of global materials use is slowing down or might eventually decline and our results indicate that an increase in material productivity is a general feature of economic development

modeling quantity discounts under general price sensitive demand functions optimal policies and relationships this paper presents models for determining optimal all unit and incremental quantity discount policies and investigates the effect of quantity discounts on increasing demand and ensuring pareto efficient transactions under general price sensitive demand functions the paper develops optimal quantity discount policies investigates their interrelationships and their benefits to both the supplier and the buyer and gains managerial insights for the scenarios of maximizing the supplier s profit and the joint profit we develop simple and efficient solution approaches for determining the all unit and the incremental optimal decision policies for general price sensitive demand functions we have three main findings first with price sensitive demand there are two incentives in offering quantity discounts increasing demand and ensuring pareto efficient transactions in most cases increasing demand dominates in justifying the offering of quantity discounts second using a single lot size associated with all efficient transactions as with the constant demand case does not hold with the price sensitive demand case third the optimal all unit quantity discount policy is equivalent to the optimal incremental quantity discount policy in benefiting both the supplier and the buyer

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

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

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

the material basis of the global economy worldwide patterns of natural resource extraction and their implications for sustainable resource use policies abstract material flow accounting and analysis mfa has been established as an influential framework for quantifying the use of natural resources by modern societies so far however no reference data for overall scale and trends of global extraction of natural resources and their distribution between different world regions has been available this paper presents the first comprehensive quantification of the material basis of the global economy i e used domestic extraction in a time series from 1980 to 2002 we analyse time trends for major material groups fossil fuels metals industrial and construction minerals and biomass disaggregated into seven world regions this allows for a an illustration of the global economy s physical growth driven by worldwide processes of economic integration over the past decades and b an indication of the worldwide distribution of environmental pressures associated with material extraction the results show that annual resource consumption of the world economy increased by about one third between 1980 and 2002 this indicates that scale effects due to economic growth more than compensated for other effects such as the relative increase of the service sectors contribution to gdp structural effect and the use of new production technologies with higher material and energy efficiency technology effect the observed growth of natural resource extraction is unevenly distributed over the main material categories with metals showing the highest growth rate the regional analysis shows the increasing importance of asia and latin america in global resource extraction on the global level material intensity i e resource extraction per unit of gdp decreased by about 25 indicating relative decoupling of resource extraction from economic growth the paper concludes with policy recommendations for a more sustainable use of natural resources

kyoto and carbon leakage an empirical analysis of the carbon content of bilateral trade abstract has the kyoto protocol induced carbon leakage we conduct the first empirical ex post evaluation of the protocol we derive a theoretical gravity equation for the carbon dioxide content of trade which accounts for intermediate inputs both domestic and imported the structure of our new panel database of the carbon content of sectoral bilateral trade flows allows controlling for the endogenous selection of countries into the kyoto protocol binding commitments under kyoto have increased committed countries embodied carbon imports from noncommitted countries by around 8 and the emission intensity of their imports by about 3 hence kyoto has indeed led to leakage

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

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

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

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

nexus between green finance non fossil energy use and carbon intensity empirical evidence from china based on a vector error correction model abstract previous studies have considered the effect of financial development on carbon emissions however few studies have explored the role of green finance in carbon mitigation to bridge this gap the current study constructs a green finance development index based on four indicators green credit green securities green insurance and green investment a vector error correction model is used to analyze relationships between the development level of green finance non fossil energy consumption and carbon intensity using data from 2000 to 2018 we find that china s green finance industry developed rapidly and improvements in the green finance development index as well as the increasing use of non fossil energy contributed to a reduction in carbon intensity simultaneously an increase in carbon intensity inhibited the expansion of non fossil energy use impeded the investment flow to green projects and ultimately led to a deterioration of green finance development in addition non fossil energy consumption in china was primarily influenced by green finance and carbon intensity with clear policy driven effects however the impacts of green finance policies continually fell short and lacked continuity this study proposes ways in which to improve the effect of green finance policy implementation expand the consumption of non fossil energy and develop a carbon trading market

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

measuring wellbeing performance of carbon emissions using hybrid measure and meta frontier techniques empirical tests for g20 countries and implications for china abstract a quantitative measure of performance that integrates national level carbon emission profiles with key parameters of social and economic wellbeing can provide an effective management tool for policy interventions this paper constructs non parametric evaluation and decomposition models using hybrid measure and meta frontier techniques the proposed models are employed to estimate the wellbeing performance of carbon emissions wpce and identify the sources of wpce inefficiency empirical analyses based on the group 20 g20 countries for the 2000 2015 period shows the worst performance is in the brics country group i e brazil russia india china and south africa known for rapid growth whereas the developed and the developing economies of the g20 group show positive trajectories of performance as for china its performance measure of wpce was the lowest among the g20 indicating significant potential for further improvement the analysis also highlights the role of managerial failure as the primary driver of inefficiency more important than technological inefficiency in explaining efficiency loss within the g20 countries this critical finding the relevance and importance of managerial capability suggests the need for a high level of attention to governance and managerial capacity to ensure continued improvements in performance on carbon emissions and human wellbeing a lesson to be drawn from this study is that china s policies to promote a low carbon economy can benefit from increased priority given to low carbon technological innovation for the energy system transition and enhancement of environmental governance and managerial capacity to achieve a long term sustainability

effects of a demand curve s shape on the optimal solutions of a multi echelon inventory pricing model abstract when a price demand relationship is needed in inventory pricing models very often a convenient typically linear function is arbitrarily chosen the common wisdom implication is that any downward sloping demand curve would lead to similar conclusions this paper applies different demand curve functions to a simple inventory pricing model and shows that while the common wisdom implication is valid for a single echelon system assuming different demand curve functions can lead to very different results in a multi echelon system in some situations a very small change in the demand curve appearance leads to very large changes in the model s optimal solutions other significant but counter intuitive effects of the demand curve form are also revealed this paper does not completely resolve the difficulties revealed by the counter intuitive effects reported here but establishing the existence of these effects represents a first step towards developing procedures to handle such effects these procedures will be necessary to ensure the reliability of many multi echelon models for products having price sensitive demands

optimal ordering discounting and pricing in the single period problem abstract the single period problem spp also known as the newsboy or newsvendor problem is to find the order quantity which maximizes the expected profit in a single period probabilistic demand framework previous extensions to the spp include in separate models the simultaneous determination of the optimal price and quantity when demand is price dependent and the determination of the optimal order quantity when progressive discounts with preset prices are used to sell excess inventory in this paper we extend the spp to the case in which demand is price dependent and multiple discounts with prices under the control of the newsvendor are used to sell excess inventory first we develop two algorithms for determining the optimal number of discounts under fixed discounting cost for a given order quantity and realization of demand then we identify the optimal order quantity before any demand is realized we also analyze the joint determination of the order quantity and initial price we illustrate the models and provide some insights using numerical examples

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

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

an empirical study of the determinants of green party voting i empirically study the determinants of individuals green voting behavior for this i make use of three datasets from germany a panel dataset and two cross sectional datasets the empirically strongest determinants are the voters attitude or distance to nuclear sites the level of schooling and net income i show that those voters with deviant attitudes or alternative world views are more likely to vote green a result of the fact that the green party has always had the position of a protest party i find little role for demographic variables like gender marital status or the number of children this is in contrast to the stated preference literature age plays a role for explaining voting behavior only insofar as it proxies for health

the food waste hierarchy as a framework for the management of food surplus and food waste the unprecedented scale of food waste in global food supply chains is attracting increasing attention due to its environmental social and economic impacts drawing on interviews with food waste specialists this study construes the boundaries between food surplus and food waste avoidable and unavoidable food waste and between waste prevention and waste management this study suggests that the first step towards a more sustainable resolution of the food waste issue is to adopt a sustainable production and consumption approach and tackle food surplus and waste throughout the global food supply chain the authors examine the factors that give rise to food waste throughout the food supply chain and propose a framework to identify and prioritize the most appropriate options for prevention and management of food waste the proposed framework interprets and applies the waste hierarchy in the context of food waste it considers the three dimensions of sustainability environmental economic and social offering a more holistic approach in addressing food waste additionally it considers the materiality and temporality of food the food waste hierarchy posits that prevention through minimization of food surplus and avoidable food waste is the most attractive option the second most attractive option involves the distribution of food surplus to groups affected by food poverty followed by the option of converting food waste to animal feed although the proposed food waste hierarchy requires a fundamental re think of the current practices and systems in place it has the potential to deliver substantial environmental social and economic benefits

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

philippine resource efficiency in asian context status trends and driving forces of philippine material flows from 1980 to 2008 abstract resource efficiency and sustainable resource management is critical to transitional economies to forward their pathway to sustainable development to date material flows analysis mfa and its database has become mature tools to diagnose the national resource utilization and efficiency but still few attentions and systematical analysis have been done for developing countries with this circumstance this paper conducted an innovative try on the in depth mfa research on philippines and its comparison in the asian context as an added value to current global mfa studies firstly philippine material flows from 1980 to 2008 and designed indicators reflecting resource utilization intensity and efficiency were analyzed and compared with other typical asian economies dematerialization analysis based on modified environmental kuznets curve ekc was further applied so as to investigate the coupling statements and trends of resource consumption and economic growth in philippines and compared with other asian countries finally driving forces for the changes of material flows were investigated with decomposition approach based on ipat impacts population amenity technology in periods divided according to key domestic development stages results highlighted a fluctuation of material flows which in line with the unstable development 1980s to early 2000s periods in philippines while in its stable development after early 2000s the ekc like curve was revealed indicating increasing resource consumption stage and requirement on strengthening resource efficiency countermeasures ipat analysis highlighted the critical role of economic instability on the fluctuation of dmc in the periods of 1980 1986 1986 1996 and 1996 2002 while in the period of 2002 2008 with economy recovery and stable development dmc increased and significantly offset by resource efficiency enhancement dmc gdp in asian context compared with mature developed countries like japan philippines didn t reach the real dematerialization stage yet while with comparison to fast developing countries like china and malaysia philippines was by far achieving the material prosperity together with economic prosperity therefore with setting stable economic as priority to enhance resource efficiency measures like cleaner production and regional eco industrial development market measures on resource price and tax as well as decision support tool development are critical to philippines future sustainable resource management with above highlights this paper expects to provide critical insights to the ever improvement of philippines and other southeast asian countries resource efficiency and resource management

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

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

real income stagnation of countries 1960 2001 abstract this paper examines the phenomenon of real income stagnation in which real income growth is uninterruptedly negligible or negative for a sizable sequence of years we analyse data for four decades from a large cross section of countries real income stagnation is a conceptually distinct phenomenon from low average growth and other features of the growth sequence that have been previously considered we find that real income stagnation has affected a significant number of countries 103 out of 168 and resulted in substantial income loss countries that suffered spells of real income stagnation were more likely to be poor in latin america or sub saharan africa conflict ridden and dependent on primary commodity exports stagnation is also very likely to persist over time countries that were afflicted with stagnation in the 1960s had a likelihood of 75 per cent of also being afflicted with stagnation in the 1990s
