structural changes in brazil s industrial economy 1960 1980 abstract this paper examines the structural changes in brazil s economy which can be observed through various censuses and input output tables in the period 1960 to 1980 the paper shows how the country s economy became more vertically integrated in those years even though it has become more outward oriented since the early days of import substitution it also considers the relations between the distribution of income and economic structure both at present and in a possible future situation of redistribution

indicators for sustainable energy development a multivariate cointegration and causality analysis from tunisian road transport sector this paper studies causal mechanism between indicators for sustainable energy development related to energy consumption from tunisian road transport sector the investigation is made using the johansen cointegration technique and the environmental kuznets curve ekc approach it examines the nexus between transport value added road transport related energy consumption road infrastructure fuel price and co2 emissions from tunisian transport sector during the period of 1980 2010 empirical results show that road transport related energy consumption transport value added transport co2 emissions and road infrastructure are mutually causal in the long run these results do not support the hypothesis of neutrality between energy and income for the tunisian road transport sector also there is a unidirectional causality running from fuel price to road transport related energy consumption with no feedback in both the short and long runs the fuel price and the road infrastructure are significant in the causal chain though the estimated long run cointegrated equation we conclude that there is an inverse n shaped relation between transport value added and transport co2 emissions with income turning point respectively equal to 75 and 579 constant 2000 tnd prices therefore our empirical findings refute the hypothesis of an inverted u shaped ekc for transport co2 emissions in tunisia the findings of this study have a number of policy implications economic growth environmental degradation energy and transportation policies should be recognized in order to improve the energy efficiency in transport sector all measures that should reduce petroleum consumption and greenhouse gas emissions without affecting economic growth may be undertaken the policymakers in tunisia should plan urban transport relocate production units improve fuel efficient vehicles and reinforce legislation on controlling emissions in order to copying with policies based on low carbon development and climate resilient strategies

exploring the influencing factors and decoupling state of residential energy consumption in shandong abstract this paper aims at analyzing the current situation of residential energy consumption in shandong identifying the influence factors governing energy consumption based on the lmdi log mean divisia index method and describing the decoupling relationship between residential energy consumption and residential income based on the tapio decoupling method the main results are as follows 1 the residential energy consumption structures of urban and rural have become multilevel furthermore the gap in per capital residential energy consumption between urban and rural regions narrowed 2 the energy intensity had an obvious inhibitory effect on decreasing urban residential energy consumption per capital income and population structure increased the urban residential energy consumption over the study period however per capital income and energy intensity played a more significant role in promoting rural residential energy consumption and the population structure decreased rural residential energy consumption during the study period the contributions from both energy consumption structure and total population effect were negligible 3 since 2000 the decoupling index for both urban and rural resident gradually declined which also shows that residential energy consumption in urban and rural regions was gradually less depend on residential income

index decomposition analysis applied to co2 emission studies index decomposition analysis ida was first extended from energy consumption to energy related co2 emission studies in 1991 since then many studies have been reported covering various countries and emission sectors however unlike the case of energy consumption studies a comprehensive literature survey that focuses specifically on emission studies has so far not been reported in this paper we attempt to fill this gap by reviewing 80 papers appearing in peer reviewed journals from 1991 to 2012 in this application area the first part of this paper deals with the developments with regard to the ida approaches used by researchers and the scope and focus of their studies in the second part the empirical results reported in the surveyed studies are analyzed consolidated and presented by emission sector the objective is to reveal the relative contributions of key effects on changes in the aggregate carbon intensity and this is done by emission sector and by country the findings of both parts are useful in understanding the development of ida in the application area of emission study as well as the key drivers of aggregate carbon intensities in the past and their possible future developments

decomposition analysis of the variations in residential electricity consumption in brazil for the 1980 2007 period measuring the activity intensity and structure effects abstract introduced at the end of the 1970s to study the impacts of structural changes on electricity consumption by industry index decomposition analysis techniques have been extended to various other areas to help in the formulation of energy policies notably in developed countries however few authors have applied these techniques to study the evolution of energy consumption in developing countries in brazil the few available studies have focused only on the industrial sector in this article we apply the decomposition technique called the logarithmic mean divisia index lmdi to electricity consumption of the brazilian residential sector to explain its evolution in terms of the activity structure and intensity affects over the period from 1980 to 2007 the technique is sufficiently robust and flexible to perform this analysis by disaggregating residential consumers by consumption classes and regions of the country among the main results is measurement of the impact of government programs for income transfer and universal service on variations in residential consumption typical of developing countries

decomposition analysis of gas consumption in the residential sector in ireland abstract to date decomposition analysis has been widely used at the macro economic level and for in depth analyses of the industry and transport sectors however its application in the residential sector has been rare this paper uses the log mean divisia index i lmdi i methodology to decompose gas consumption trends in the gas connected residential sector in ireland from 1990 to 2008 which despite an increasing number of energy efficiency policies experienced total final consumption growth of 470 the analysis decomposes this change in gas consumption into a number of effects examining the impact over time of market factors such as a growing customer base varying mix of dwelling types changing share of vacant dwellings changing size of new dwellings the impact of building regulations policy and other factors such as the weather the analysis finds the most significant effects are changing customer numbers and changing intensity the analysis also quantifies the impact of building regulations and compares it with other effects such as changing size of new dwellings by comparing the historical impact on gas consumption of policy factors and non policy factors this paper highlights the challenge for policy makers in achieving overall energy consumption reduction

long term changes in co2 emissions in austria and czechoslovakia identifying the drivers of environmental pressures this study presents fossil fuel related co2 emissions in austria and czechoslovakia current czech republic and slovakia for 1830 2000 the drivers of co2 emissions are discussed by investigating the variables of the standard kaya identity for 1920 2000 and conducting a comparative index decomposition analysis proxy data on industrial production and household consumption are analysed to understand the role of the economic structure co2 emissions increased in both countries in the long run czechoslovakia was a stronger emitter of co2 throughout the time period but per capita emissions significantly differed only after world war i when czechoslovakia and austria became independent the difference in co2 emissions increased until the mid 1980s the period of communism in czechoslovakia explained by the energy intensity and the composition effects and higher industrial production in czechoslovakia counterbalancing factors were the income effect and household consumption after the velvet revolution in 1990 czechoslovak co2 emissions decreased and the energy composition effect and industrial production lost importance despite their different political and economic development austria and czechoslovakia reached similar levels of per capita co2 emissions in the late 20th century neither austrian eco efficiency nor czechoslovak restructuring have been effective in reducing co2 emissions to a sustainable level

effects of urbanisation on energy consumption in china as a key issue in china s economic development urbanisation creates increasing pressure on energy supply and the natural environment thus a better understanding of the relationship between urbanisation and energy consumption is necessary for chinese decision makers at various levels to address energy security and sustainable economic and social development this paper empirically investigates the effects of china s urbanisation on residential energy consumption rec and production energy consumption pec through a time series analysis the results show that compared with rural areas urbanisation slows per capita rec growth because of the economy of scale and technological advantages associated with urbanisation but has greater promotional effects on the growth of rec and the improvement of rec structure the economic growth caused by urbanisation most significantly contributes to an increase in pec whereas technological advancement was found to reduce the scale of pec except from 2001 to 2005 finally the structural effect of the energy supply increased rather than decreased china s pec and the effect of industrial structure adjustment on pec was found to be insignificant

energy intensity developments in 40 major economies structural change or technology improvement this study analyzes energy intensity trends and drivers in 40 major economies using the wiod database a novel harmonized and consistent dataset of input output table time series accompanied by environmental satellite data we use logarithmic mean divisia index decomposition to 1 study trends in global energy intensity between 1995 and 2007 2 attribute efficiency changes to either changes in technology or changes in the structure of the economy and 3 highlight sectoral and regional differences we first show that heterogeneity within each sector across countries is high these general trends within the sectors are dominated by large economies first and foremost the united states in most cases heterogeneity is lower within each country across the different sectors regarding changes of energy intensity at the country level improvements between 1995 and 2007 are largely attributable to technological change while structural change is less important in most countries notable exceptions are japan the united states australia taiwan mexico and brazil where a change in the industry mix was the main driver behind the observed energy intensity reduction

decomposition of ireland s carbon emissions from 1990 to 2010 an extended kaya identity in recent decades ireland has been an important example of a development pathway where rapid economic growth was accompanied by rising energy demand and increasing carbon emissions understanding the driving forces of carbon emissions is necessary for policy formulation and decomposition analysis is widely used for this purpose this study uses an extended kaya identity as the scheme and applies the log mean divisia index lmdi i as the decomposition technique change in carbon emissions is decomposed from 1990 to 2010 and includes a measure of the effect of renewable energy penetration results illustrate that scale effects of affluence and population growth act to increase emissions and are countered primarily by energy intensity and fossil fuel substitution renewable energy penetration has a minor effect but has been increasing in recent years policy will need to significantly reduce intensity and increase renewables if applicable targets are to be reached this requires not only a comprehensive suite of policies and measures but emphasis on the development path and non technical change for optimal outcomes

decoupling factors on the energy output linkage the spanish case the recent increase of energy intensity in spain and the ratification of the kyoto protocol call for the implementation of energy policies in spain in this paper we investigate the relationship between gross domestic product gdp and energy consumption ec by taking into account several decoupling factors that can affect this linkage specifically we have considered the temporal aggregation of data and its seasonal adjustments the multivariate methodology the substitution between ec and other inputs and the technological changes empirical tests reveal a long run relationship between ec and gdp that can only be established in a complete way with a multivariate cointegration analysis furthermore a short run unidirectional causality from ec to economic growth is found therefore primary ec plays an important role as a limiting factor for economic growth in spain in the short run

long term diversification paths and energy transitions in europe the concentration of the energy mixes of eight european countries is measured latecomers historically enjoyed lower levels of concentration in their energy mixes early comers followed an inverted u path of concentration latecomers a u path a time effect and size effect explains the different patterns small energy consuming countries will be able to do faster transitions

decomposition analysis for assessing the progress in decoupling industrial growth from co2 emissions in the eu manufacturing sector decomposition analysis is used in this paper not only to explain changes in industrial co2 emissions but also to comparatively evaluate the progress made in 14 eu countries in decoupling emissions from industrial growth the analysis is performed for the period 1990 2003 by distinguishing two time intervals for assessing progress prior to and following the agreement on the kyoto protocol the refined laspeyres model is used to determine the impact of 5 explanatory factors output energy intensity structure fuel mix and utility mix the obtained results are further elaborated in order to assess the real efforts undertaken in each country and their effectiveness in dissociating the economic and environmental dimensions of development moreover a rescaling procedure is implemented in order to adjust efforts to the average progress in the eu and proceed to a fair comparative evaluation it is found that most eu countries made a considerable but not always sufficient decoupling effort while no significant acceleration is observed in the post kyoto period

the incidence of regulatory rents in the motor carrier industry this article focuses on two questions in the debate over motor carrier regulation first did regulation create eliminate or have no effect on monopoly rents in the trucking industry second ifthere were rents what was their incidence were they received by owners oftrucking firms dissipated through higher costs or captured by the teamsters union data on share price responses to deregulation announcements reveal declines in expected profits of 8 19 of totalfirm value this suggests that regulation created monopoly profits and indicates that at least some of these rents accrued to owners of trucking firms firms responses to regulatory change are modelled as functions of company s operating characteristics and measures of unionization operating efficiency and service characteristics are shown to affect the impact of deregulation on share values

towards a sustainable growth in latin america a multiregional spatial decomposition analysis of the driving forces behind co2 emissions changes abstract this paper aims to understand the driving forces behind the growth of co2 emissions in latin america as a region by groups of countries according to their behaviour in terms of growth of income and co2 emissions per capita and by countries during 1990 2013 the main drivers for the latin america region are the activity and the population effects followed by the fossil fuel and the carbonisation effects while the intensity effect is revealed as the only inhibitor the lessons from latin america s group of countries are the following first the necessary decoupling between the growth of co2 emissions and the economic activity has not taken place the population growth also being an important driver effect second the groups of countries with the highest co2 emissions growth show the highest population and fossil fuel effects this latter confirms the scant efforts made to reduce the weight of fossil fuels in the total primary energy supply third the energy intensity has become the most important inhibitor of co2 emissions for those countries that are not able to substitute fossil fuels so easily finally the desirable increase of less pollutant fossil fuels or even the increase of renewable energies has not yet been achieved

decoupling china s carbon emissions increase from economic growth an economic analysis and policy implications as the world s second largest carbon emitter china has long been criticized as a free rider benefiting from other countries efforts to reduce greenhouse gas emissions but not taking responsibility for its own emissions china has been singled out as one of the major targets at the subsequent negotiations after the kyoto meeting bq analyzing the historical contributions of interfuel switching energy conservation economic growth and population expansion to china s co2 emissions during 1980 97 this article clearly demonstrates that the above criticism is unjustified moreover given the fact that the role of china is an issue of perennial concern at the international climate change negotiations the article envisions some efforts and commitments that could be expected from china until its per capita income catches lip with the level of middle developed countries by emphasizing the it win win strategies these efforts and commitments are unlikely to jeopardize china s economic development and at the same time would give the country more leverage at the international climate change negotiations subsequent to the buenos sires meeting c 2000 elsevier science ltd all rights reserved

trade liberalization and rising wage inequality in latin america reconciliation with hos theory abstract the paper puts forward the hypothesis that the transitory effects of trade liberalization on wage inequality can differ from the long run outcome in cases where the hos theory predicts a decline in wage inequality in the long run a temporary rise can nevertheless occur due to i the asymmetries in the speed of contraction in the import sector and expansion in other sectors and ii the capital skill complementarity in production the asymmetric contraction and expansion causes a transitory capital accumulation that boosts the relative and the real wage of skilled labor due to capital skill complementarity although the long run hos fundamentals are therefore dominated in the short run by the transient effects arising due to capital skill complementarity the observed rise in wage inequality is nonetheless consistent with the hos theory appropriately extended to a dynamic setting

decoupling economic growth from carbon dioxide emissions in china a sectoral factor decomposition analysis china is facing the dilemma of how to coordinate economic development and carbon dioxide co2 emissions reduction this paper investigates the decoupling effect of economic growth from co2 emissions in china during the period 1992 2012 using the logarithmic mean divisia index lmdi method we decompose the driving forces of the decoupling of economic growth from co2 emissions in china s five major economic sectors into several factors and measure the contribution of each factor to the decoupling of china s overall economy from co2 emissions the results show that china performed the weak decoupling of economic growth from co2 emissions during 1992 2012 and so did all its five major sectors such a state did not occur smoothly and presented five different stages energy intensity and economic activity level were the most important factors affecting the decoupling in china energy intensity decreased in all sectors indicating a large acceleration for the sectoral decoupling states this finding is applicable to process carbon intensity in industrial sector and energy emission factor in agricultural industrial construction and service sectors in terms of sectoral effects on the decoupling in china industrial sector played a dominant role while construction sector had the most marginal influence the economic activity level and economic share of industrial sector exerted the most negative effects on the decoupling the energy intensity of industrial sector played a key role in promoting the national decoupling state while the energy emission factor of agricultural sector contributed the least

decoupling co2 emissions and industrial growth in china over 1993 2013 the role of investment abstract since industrial sector is a leading energy consumer and co 2 emitter in china the degree of the decoupling of co 2 emissions and industrial growth plays a critical role in realizing the energy conservation and emission reduction goals of china this is the first study to present a specific investigation on the decoupling of co 2 emissions and industrial growth in china from 1993 to 2013 using an extended logarithmic mean divisia index lmdi model focusing on both energy related and process related co 2 emissions and introducing three novel investment factors i e investment scale investment share and investment efficiency we highlight and explore the remarkable role of investment in the mitigation and decoupling of co 2 emissions with industrial growth the results show that china s industrial sector experienced the weak decoupling during 1993 2013 the investment scale is the most important factor responsible for the increase in co 2 emissions and the inhibition of the decoupling the investment efficiency effect has a volatile trend and overall it plays the most significant role in reducing co 2 emissions followed by the energy intensity effect and process carbon intensity effect whereas the energy mix carbon coefficient and investment share have marginal effects among 36 industrial sub sectors the seven factors of rcmcp raw chemical materials and chemical products nmp nonmetal mineral products and spfm smelting and pressing of ferrous metals have significant effects on the decoupling thus the three sub sectors should be among the top concerns for abating co 2 emissions finally we provide policy recommendations considering both conventional and investment factors for china s industrial sector to realize emission reduction targets

manufacturing energy use in oecd countries decomposition of long term trends abstract in this paper we examine manufacturing energy use in 13 oecd countries over the period 1971 1995 we describe changes in aggregate energy intensity using the adaptive weighting divisia decomposition method we contrast the development in the periods after the oil price shocks of 1973 and 1979 with the period of relatively stable energy prices after the oil price crash of 1986 the results show that manufacturing output grew in most countries pushing up energy use the share of electricity increased in almost every sector while there was a clear trend away from oil and coal towards natural gas changes in the structure of output drove up energy use between 1973 and 1994 in some countries and down in others changes in energy intensities had a profound and downward effect on manufacturing energy use in all countries however contrasting the period after oil prices fell in 1986 with earlier years we see that for most countries the rate of energy intensity decline slowed slightly but did not reverse with falling prices in a few countries efficiency improvements continued to have a strong effect this suggests that even without higher prices improvements of energy efficiency seems to take place

the demand for road diesel in canada abstract in this paper we estimate the demand for road diesel in canada using aggregate annual data for the period 1986 2008 using a partial adjustment model pam we find short and long run price elasticities of 0 43 and 0 8 respectively however using cointegration techniques we obtain price elasticities that are 30 to 50 lower the short run elasticity with respect to gdp per capita is evaluated at 0 5 with the pam and 1 55 with cointegration in the long run both estimation techniques indicate an income elasticity around 0 9 our results underline the importance of controlling for the expansion of the primary sector which has been characterizing the canadian economy in the 2000s

decomposition of co2 emissions change from energy consumption in brazil challenges and policy implications this study evaluates the changes in co2 emissions from energy consumption in brazil for the period 1970 2009 emissions are decomposed into production and consumption activities allowing computing the full set of energy sources consumed in the country this study aims to develop a comprehensive and updated picture of the underlying determinants of emissions change from energy consumption in brazil along the last four decades including for the first time the recently released data for 2009 results demonstrate that economic activity and demographic pressure are the leading forces explaining emission increase on the other hand carbon intensity reductions and diversification of energy mix towards cleaner sources are the main factors contributing to emission mitigation which are also the driving factors responsible for the observed decoupling between co2 emissions and economic growth after 2004 the cyclical patterns of energy intensity and economy structure are associated to both increments and mitigation on total emission change depending on the interval the evidences demonstrate that brazilian efforts to reduce emissions are concentrated on energy mix diversification and carbon intensity control while technology intensive alternatives like energy intensity has not demonstrated relevant progress residential sector displays a marginal weight in the total emission change

comparing structural decomposition analysis and index to analyze and understand historical changes in economic environmental employment or other socio economic indicators it is useful to assess the driving forces or determinants that underlie these changes two techniques for decomposing indicator changes at the sector level are structural decomposition analysis sda and index decomposition analysis ida for example sda and ida have been used to analyze changes in indicators such as energy use co2 emissions labor demand and value added the changes in these variables are decomposed into determinants such as technological demand and structural effects sda uses information from input output tables while ida uses aggregate data at the sector level the two methods have developed quite independently which has resulted in each method being characterized by specific unique techniques and approaches this paper has three aims first the similarities and differences between the two approaches are summarized second the possibility of transferring specific techniques and indices is explored finally a numerical example is used to illustrate differences between the two approaches

decoupling waste generation from economic growth a cge analysis of the swedish case abstract over the past decades we have seen the quantities of solid waste increase in close relation to economic growth to tackle this problem of continuing waste growth the eu has on its agenda that waste generation should decouple from economic growth within the eu in the future sweden also has stated a target of non increasing future waste quantities the strength of the policy measures needed to attain this target is here illustrated by comparing the waste intensity outcomes in a decoupling scenario and a baseline scenario of the swedish economy 2006 2030 a computable general equilibrium cge model is used for linking waste generation to firms material input firms production and households consumption when projecting future quantities of hazardous and non hazardous waste in sweden we show that to offset the effect of economic growth on waste generation in the decoupling scenario the intensities of material related wastes must decrease at a yearly rate that is about twice the historically estimated reduction rate used in the baseline scenario the reduction in the intensities of waste related to firms production and households consumption must also be substantial compared to historical estimates

the future natural gas consumption in china based on the lmdi stirpat plsr framework and scenario analysis abstract due to the growing pollution concerns in china there have been major efforts to design interrelated environmental protection policies as the policy of reducing coal consumption is implemented china s natural gas consumption is expected to commensurately rise such a trend may lead to the significant impacts on china s energy security and the global gas market this paper empirically investigates the relationship between the natural gas consumption and influencing factors in a comprehensive lmdi stirpat plsr framework it is found that fossil energy structure and non clean energy structure are the most important factors followed by urbanization per capita gdp industrialization and industrial energy intensity and then these factors from lmdi decomposition are innovatively divided into economic development and cleaning indicators when using scenario analysis to forecast china s natural gas consumption the prediction results suggest that economic development with high clean energy system would make a significant increase in gas consumption a commensurate increase in demand even the system of economic energy under scenario of low economic development and low clean as china would depend on gas imports to meet this demand there may be a serious supply shortage by 2020 therefore the government should consider the future energy security issue in making economic and environmental policies

swedish co2 emissions 1993 2006 an application of decomposition analysis and some methodological insights this study undertakes a decomposition analysis to identify the drivers of carbon dioxide emissions change in the swedish business and industry sectors 1993 2006 on aggregate energy intensity decreased but this does not seem to have been very important for reducing emissions rather fuel substitution seems to have been more important which is in line with findings from the decomposition literature on sweden however at the sectoral level we find no clear pattern of the effect of fuel substitution and energy intensity on emissions we also draw some methodological conclusions decomposition analysis should be undertaken at the most disaggregate level possible assessing decomposition results by summing results over several time periods leads to biased results and decomposition analysis should not be based only on some initial and final years of a long time period furthermore we address the problem of double counting energy flows in decomposition analysis of aggregate effects when the energy sector is included and point out potential problems related to output measured in monetary terms

factors shaping aggregate energy intensity trend for industry energy intensity versus product mix understanding the mechanisms of change of energy consumption in industry has attracted much attention since the 1973 world oil crisis a popular line of research has been to decompose changes in the aggregate energy intensity of industry to give the relative impacts arising from energy intensity change and product mix change using a decomposition technique many empirical studies covering a large number of countries have been reported the main objective of this paper is to put together the empirical results reported in these studies in a coherent framework and identify possible systematic features of particular interest are the basic trends in this line of research the relative importance of energy intensity change and product mix change possible variations over time and between country groups in the energy impacts of these changes and inconsistencies in findings among studies an overview of the decomposition technique including its strengths weaknesses and role in industrial energy consumption studies is also presented

study on decoupling analysis between energy consumption and economic growth in liaoning province abstract since 1978 liaoning province has experienced spectacular economic growth which has led to more energy consumption the purpose of this paper is to explore the decoupling status between energy consumption and economic growth in liaoning province firstly the generalized lmdi method is used to explore the driving forces governing production energy consumption in liaoning province then the combination of tapio decoupling indicator and generalized lmdi method is utilized to study what the decoupling status occurred in liaoning province and why the decoupling status appeared during the study period only four decoupling status occurred expansive negative decoupling expansive coupling weak decoupling and strong decoupling the energy intensity decoupling effect played a positive role in the appearance of decoupling however the economic structure decoupling effect and investment decoupling effect played a negative role in the appearance of decoupling over the study period the energy structure decoupling effect and labour decoupling effect played a relative small role in the appearance of decoupling

a theory of dual labor markets with application to industrial policy discrimination and keynesian unemployment this paper develops a model of dual labor markets based on employers need to motivate workers in order to elicit effort from their workers employers may find it optimal to pay more than the going wage this changes fundamentally the character of labor markets the model is applied to a wide range of labor market phenomena it provides a coherent framework for understanding the claims of industrial policy advocates it also can provide the basis for a theory of occupational segregation and discrimination that will not be eroded by market forces finally the model provides the basis for a theory of involuntary unemployment

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

driving forces for aggregate energy consumption a cross country approach abstract although a cornerstone for development past and current energy use has often posed a major challenge for policymakers with respect to planning and management within this context in this paper an updated multi sectorial cross country assessment of energy consumption trends was undertaken aiming at identifying the main drivers of changes in aggregate energy consumption these drivers have been interpreted in the light of the policy measures that have been implemented over the years by different countries to achieve a sustainable development of the energy sector the cross country assessment encompasses a set of developed united kingdom portugal and spain and emerging brazil china and india countries resorting to the logarithmic mean divisia index lmdi decomposition method changes in the aggregate energy consumption were decomposed into three main explanatory effects activity structure and intensity the major findings achieved reflect the relevance of intensity and activity effects in detriment of the structural effect the assessment of energy consumption trends using the lmdi decomposition method provides critical information regarding which is the dominant factor that should be focused in policy design

bigger cakes with fewer ingredients a comparison of material use of the world economy the amount of materials used worldwide in production and consumption increased by 56 from 1995 to 2008 using an index decomposition analysis based on the logarithmic mean divisia index we investigate the drivers of material use both on a global and a country scale we exploit a panel dataset of 40 countries accounting for 75 of worldwide material extraction and 88 of gdp from 1995 to 2008 the results show that economic growth and structural change towards material intensive countries explain most of the growth in global material use slight gains in material efficiency and falling importance of material intensive sectors have decelerating effects the country level analysis reveals substantial heterogeneity some nations exhibit stable or falling material use while it increases notably in most countries improving material efficiency is able to dampen growth of material use in important industrializing nations like china or india

driving factors of carbon emissions embodied in china us trade a structural decomposition analysis abstract based on the environmental multi regional input output model this study employed structural decomposition analysis to investigate the driving factors of carbon emissions embodied in china us trade over the period of 1995 2009 effective driving factors were classified into six groups and each group included both factors at home and abroad the results show that factors trade structure of intermediate products at home and export market shares of final products at home presented the largest positive impacts to increments in carbon emissions embodied in chinese exports to the us while the majority of negative impacts was generated by changes in energy intensities at home the increment in carbon emissions embodied in us exports to china was mostly contributed by total demands abroad impacts of other driving factors were much smaller at the sectoral level both positive and negative impacts of driving factors were largely limited to a few sectors e g textiles products machinery transport equipment and electrical equipment here positive impacts were mostly contributed by export market shares of final products at home and total demands abroad and negative impacts were mainly contributed by energy intensities at home policy implications deduced from the results were discussed

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

decomposition of aggregate carbon intensity for freight trends from 10 oecd countries for the period 1971 1993 abstract historical patterns of aggregate carbon intensity from freight are different than those from other sectors while aggregate carbon intensity declined for all other sectors aggregate carbon intensity for freight increased the adaptive weighted divisia rolling base year index specification is applied to carbon emissions from the freight sector of 10 oecd countries for the period 1970 1993 increases in aggregate carbon intensity for nine of the countries range from less than 20 to over 150 and may be primarily attributed to shifts in modal structure toward more carbon intensive modes these increases in aggregate carbon intensity are driven primarily by an increase in activity which parallels the growth in gdp furthermore changes in fuel price and vehicle purchase taxes do not appear to be effective instruments for reducing energy consumption for this end use alternative policy options including less carbon intensive fuels and technologies and reduced congestion appear to be better choices

measuring the effects of regulation with stock price data this article examines the usefulness of stock returns in measuring the effects of regulation when the dates on which market expectations change are not known and standard sources e g the wall street journal are used to choose announcement dates twenty major changes in regulatory constraint since 1887 are considered tests using either monthly or daily data are found to have surprisingly little ability to detect the effects of regulation the evidence shows that formal regulatory announcements are generally anticipated in cases where it is unclear when expectations change

decoupling between human development and energy consumption within footprint accounts abstract historically the growth of energy consumption has fuelled human development but this approach is no longer socially and environmentally sustainable recent analyses suggest that some individual countries have responded to this issue successfully by decoupling total primary energy supply from human development increase however globalisation and international trade have allowed high income countries to outsource industrial production to lower income countries thereby increasingly relying on foreign energy use to satisfy their own consumption of goods and services accounting for the import of embodied energy in goods and services this study proposes an alternative estimation of the decoupling index based on the total primary energy footprint rather than total primary energy supply an analysis of 126 countries over the years 2000 2014 demonstrates that previous studies based on energy supply highly overestimated decoupling footprint based results on the other hand show an overall decrease of the decoupling index for most countries 93 out of 126 there is a reduction of the number of both absolutely decoupled countries from 40 to 27 and relatively decoupled countries from 29 to 17 and an increase of coupled countries from 55 to 80 furthermore the study shows that decoupling is not a phenomenon characterising only high income countries due to improvements in energy efficiency but is also occurring in countries with low human development index and low energy consumption finally six exemplary countries have been identified which were able to maintain a continuous decoupling trend from these exemplary countries lessons have been identified in order to boost the necessary global decoupling of energy consumption and achieved welfare

does ecological economics have a future contradiction and reinvention in the age of climate change abstract this paper addresses the role of neoclassical methodologies in ecological economics and the contradictions these methodologies pose to the field s critical founding principles we first consider robert costanza s treatment of nicholas stern s global deal and then survey climate change related articles published in this journal over the past five years this survey reveals how mainstream neoclassical methodologies dominate discourse and do so by marginalizing more critical political economy analyses this situation imperils the field s founding vision of a no growth steady state it also fails to address the related growth dynamics of capitalism without such a critical treatment the field s formal embrace of methodological pluralism actually entails an ideological empiricism that renders ecological economics theoretically incoherent this situation undermines the field s historical promise as an alternative economic paradigm ecological economics now faces a problematic future its survival in a form faithful to its founding vision will require an explicit choice to address its internal contradictions and reinvent itself in ways relevant to our contemporary context without such a choice ecological economics will likely succumb to an implicit acceptance of the hegemony of mainstream economic methodologies and their pro growth imperatives

impacts of urbanization on renewable energy consumption in china abstract in this paper we used the logarithmic mean divisia index method to investigate the impact of urbanization on renewable energy consumption growth recg the growth in renewable energy consumption is attributed to the urbanization effect energy mix effect energy intensity effect economic effect and population effect recg can be roughly divided into the slow growth stage the fluctuant growth stage and the accelerated growth stage the results showed that the energy mix effect economic effect and population effect positively affected recg however a significantly negative relationship was found between energy intensity and recg furthermore the contribution of urbanization differed in recg stages and urbanization contributed more to the total energy consumption growth than to recg this study would thus provide policymakers with insights about the link between urbanization and renewable energy consumption

the impact of china s differential electricity pricing policy on power sector co2 emissions abstract this article investigates the impact of china s differential electricity pricing policy on power sector co 2 emissions using the logarithmic mean divisia index method the differential pricing policy intended to reduce energy intensity in manufacturing is being implemented in eight electricity intensive industries the study finds that during 2004 2009 the policy accounted for a drop of roughly 115 twh in electricity use which amounted to a reduction of 82 million tons of co 2 emissions the policy has been most effective in reducing electricity use in the nonferrous metal smelting and rolling industry and least effective in the ferrous metal smelting and rolling industry because the differential pricing policy has had significantly different effects across industries improving the policy s design and implementation going forward will require a more detailed understanding and analysis of how it can be better tailored to individual industries

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 modest environmental relief resulting from the transition to the service economy a service transition is supposed to lead to the decline of energy intensity energy gdp we argue that this interpretation is overly optimistic because the shift to a service economy is somewhat of an illusion in terms of real production several recent studies of structural effects on energy intensity have made the error of using sector shares in current prices combined with gdp in constant prices which is inconsistent and ignores the different behaviour of prices across sectors we use the more correct method of sector shares in constant prices and make an attempt to single out the effect from the real service transition by using two complementary methods shift share analyses in current and constant prices and logarithmic mean divisia index lmdi for 10 developed and 3 emerging economies a service transition is rather modest in real terms the major driver of the decline in energy intensity rests within the manufacturing sector meanwhile the transition to a service sector had a small downward impact on energy intensity in 7 of the developed countries and no impact in the others for emerging economies like brazil mexico and india it is the residential sector that drives energy intensity down because of the declining share of this sector as the formal economy grows and as a consequence of switching to more efficient fuels less

the wealth effect of merger activity and the objective functions of merging firms abstract this paper studies the net effects of the long run sequence of events leading to merger and of merger per se on shareholder wealth the appropriate measure of the wealth effect is shown to be the abnormal dollar return cumulated over time using this measure the long run wealth effect of the event sequence culminating in merger is significantly negative for acquiring firms for acquired firms the effect is negative but not significant the immediate impact of merger per se is positive and highly significant for acquired firms but larger in absolute value and negative for acquiring firms the evidence also reveals that measured abnormal rates of return to acquiring firms are sensitive to a slight variation in model specification and dependent on firm size with smaller firms earning significantly negative post merger returns

decomposing the decoupling of co2 emissions and economic growth in brazil abstract this paper examines the occurrence of a decoupling between the growth rates in economic activity and co 2 emissions from energy consumption in brazil from 2004 to 2009 this decoupling was highlighted when economic activity and co 2 emissions moved in opposite directions in 2009 more generally we observe several periods of relative decoupling in brazil but not to the extent witnessed in 2009 to identify the determinants of emissions change we develop a decomposition model based on a log mean divisia index lmdi framework the results indicate that the carbon intensity and energy mix are the main determinant of emissions reduction in brazil between 2004 and 2009 modifications in the economy structure are also associated to emission mitigation in the period such evidence demonstrates similarities with events of decoupling registered for the interval 1980 1994 in brazil finds from brazil differ from observations in other countries in which improvement in energy intensity has been the most common determinant of emissions reduction

does urbanization drive economic growth decoupled from energy consumption in china s logistics abstract logistics has gradually become a major energy consumer in china along with urbanization and e commerce a better understanding of economic growth decoupled from energy consumption in logistics could relieve the pressure of energy supply and environmental pollution a combined model based on the tapio decoupling model kaya identity and log mean divisia index was proposed to decompose the impact of urbanization into 4 related factors comparative analysis was applied to investigate the similarities of and differences in the urbanization related factors affecting the decoupling state of provinces the main results were as follows 1 weak decoupling was the dominant state of logistics in china during 2007 2016 there were weak decoupling and strong decoupling in most of the observation period in the eastern region while there was no strong decoupling in the central and western regions 2 from the national perspective urbanization related factors had very significant but different impacts population quantity spatial structure and spatial expansion were the key inhibitors while population density was the main contributor 3 from the regional perspective the patterns of urbanization related factors in the three regions were similar population density had a positive but decreasing effect on decoupling in the three regions especially the western region population quantity had an increasing negative effect on decoupling in the three regions especially the central and western regions spatial expansion had an increasing negative effect on decoupling in the eastern and western regions but a decreasing negative effect in the central region and spatial structure had a stable negative effect on the three regions finally some policy implications were proposed

energy conservation and co2 emission reduction in china s 11th five year plan a performance evaluation in the 11th five year plan fyp 2005 2010 the chinese government initiated a series of energy saving and emission reduction policies in many key fields in response to environmental pollution and climate change this paper quantitatively evaluates the performance of energy conservation and co2 emission reduction in this period the impact of these policies and potentials by integrating the contributions of energy conversion efficiency and energy utilization efficiency improvement industrial restructuring fuel mix shift and renewable energy development in a unified framework as a first attempt to introduce energy conversion efficiency improvement into a decomposition approach comprehensive and specific policies are summarized as a policy list to be investigated the results show that energy intensity and conversion efficiency effects were mainly responsible for driving down energy consumption by 637 4 mtce and 85 4 mtce respectively and they reduced co2 emissions by 1345 3 mt and 243 8 mt respectively due to a significant improvement in the 11th fyp period most of the contributions made by the conversion efficiency effect 94 come from thermal power generation and the emission coefficient effect reduced co2 emissions by 17 4 mt through developing renewable energy economic growth is still the biggest driver of energy consumption and increasing emissions while industrial restructuring and fuel mix shift effects contributed relatively little developing renewable energy and promoting economic restructuring to limit the increase of energy intensive sectors are still the main challenges and the next policy focus to achieve the targets for energy saving and carbon emission reduction in the 12th five year plan

an analysis of the decoupling relationship between co2 emission in power industry and gdp in china based on lmdi method abstract china predominantly relies on thermal power generation to meet its power requirement which has led to a major increase in total co2 emission and poses a huge threat to the development of power industry in order to reduce co2 emission in power industry and develop economy simultaneously it is necessary to study how to achieve the strong decoupling relationship between co2 emission in power industry and gdp in china however such studies are relatively limited so far thus this paper mainly inquiries the major driving factors on the decoupling during the period of 1985 2016 first the decoupling state in china is quantified by using the tapio decoupling indicator then this paper carries out the decomposition of the decoupling index to explore the driving factors affecting the decoupling by the logarithmic mean divisia index lmdi method and kaya identity equation finally energy consumption in power generation thermal power structure power generation structure transmission and distribution loss electrification energy intensity and economic scale are explored to discuss the decoupling relationship with respect to the co2 emission reduction the results show that the decoupling relationship is in an alternating state between weak decoupling and expansive negative decoupling in 1985 2016 and the influences of seven factors on the decoupling relationship are of difference wherein energy intensity as well as energy consumption in power generation promotes the decoupling while both the economic scale and electrification are the two main factors that inhibit the decoupling the other three factors have relatively weak effects therefore based on the empirical results this paper puts forward some policy suggestions to effectively promote the decoupling between china s electric co2 emission and economic growth

a comparative study on decoupling relationship and influence factors between china s regional economic development and industrial energy related carbon emissions abstract to study the relationship between china s regional economic development and industrial carbon emission reveal the major influencing factors and mechanism of carbon emission change in all regions and provide theoretical evidence for governments to formulate emission reduction strategies and policies big data analysis and the tapio extended model were adopted to quantitatively analyse the decoupling relationship between carbon emission and economic growth in eight major regions of china between 1996 and 2012 logarithmic mean divisia index lmdi was also applied to decompose the main factors affecting carbon emission change in all regions the results show that 1 the proportions of industrial energy related to carbon emissions in central china and the beijing tianjin region decreased year by year while the opposite was the case in coastal areas of northern china furthermore the proportions in other regions basically remained unchanged 2 a weak decoupling relation between industry energy carbon emission and economic growth was found in most regions except in northwest china during the period 1996 2000 southwest china south and north coastal regions during the period 2001 2005 beijing and tianjin during the period 2010 2012 energy consumption decoupling factors exerted a consistent positive effect on industry energy carbon emission decoupling with decoupling impact greater than emission factors 3 the overall level of carbon emission reduction technology in china was low and backwards and limited contributions have been made to economic growth and industry energy carbon emission decoupling development emphases of decoupling should be put on energy saving technology promotion industry structure upgrading and energy structure improvement in the future 4 economic intensity effect has exerted the most powerful positive influence on carbon emissions except in developed areas and the positive effect was weaker than that in other regions

china s strategy for carbon intensity mitigation pledge for 2020 evidence from a threshold cointegration model combined with monte carlo simulation methods abstract this paper specifies a nonlinear threshold cointegration to analyze the nonlinear relationship between carbon intensity and economic growth in china the tests and estimated results clearly confirm that fast paced economic growth that is the growth rate of gross domestic product gdp is greater than 9 053 impede the reduction of carbon intensity because it weakens the negative effects of tertiary industry development and energy efficiency on carbon intensity while it also increases the positive effect of unclean energy mix on carbon intensity in order to find a moderate range of economic growth rate that is both beneficial for industrial structuring and energy mix transformation and at the same time facilitate reduction in carbon intensity monte carlo simulations are employed the results show when the growth rate of gdp is between 7 and 8 4 it can promote structural bonus of industrial structure and energy consumption structure on carbon intensity and carbon intensity in 2020 would decline by about 40 60 compared to 2005 level these conclusions mean it is necessary for china to carefully set its economic growth target through transformation and optimization of its economic structure and energy mix in order to continuously reduce carbon intensity

changes in carbon intensity in china empirical findings from 1980 2003 china experienced sustainable rapid economic growth over the period 1980 2003 but at the same time energy related carbon intensity showed a downward trend it begs the question therefore what factors were driving this decline in carbon intensity and will this decline be maintained in future moreover what measures can be adopted to ensure a continual decline in carbon intensity these questions led to increased research in the factors governing co2 emission in china this paper quantifies the driving force behind china s primary energy related carbon intensity and measures the material production sectors final energy related carbon intensity our results show that the overwhelming contributor to the decline of energy related carbon intensity was the reduction in real energy intensity however policies that focus only on the decline in energy intensity are insufficient to further decrease carbon intensity the change of primary energy mix can improve the decline of carbon intensity this should focus on the material production sectors development strategies and final energy use greater emphasis should be given to secondary industry which needs national and regional governments policy support

assessing eco efficiency through the dea analysis and decoupling index in the latin america countries abstract this study was developed according to a two step approach in the first step we provide an investigation of the changes in eco efficiency under constant and variable return to scale while on a second step the evaluation of the decoupling elasticity will be given the impacts of energy economic and environmental determinants inputs on the performance indicators of eco efficiency were calculated as the inverse of the carbon intensity ratio of the gdp over the co2 emissions both from the world development indicators database the changes in eco efficiency and the decoupling elasticity between co2 emissions and economic growth changes data was used for 16 latin america countries according to five year periods from 1994 to 2013 for all the five time span considered it is worth noting that the degree of technical efficiency for the latin america countries is lower than the degree of technological efficiency thus indicating that a portion of the overall inefficiency is due to the fact that these countries are producing below the production frontier rather than to an inefficient use of technology on average the results have confirmed that the technological scale change in energy production is the dominant factor influencing the optimal production frontier in the sample of countries under analysis complementarily according to the mixed results from the decoupling analysis we may conclude that the increase decrease of the co2 per capita emissions was due to other economic and environmental factors rather than to a negative positive effect of the gdp growth rate

walking away from a low carbon economy recent and historical trends using a regional decomposition analysis using the latest available data this brief article attempts to provide the first regional decomposition analysis of co2 emissions from fuel combustion covering eight regions of the world determinants are estimated in relative and absolute terms for the period 1971 2010 we take the 2010 global surge in co2 emissions as an entry point for the analysis overall results show that most regions have recently performed worse than their historical trends and lack of meaningful progress is identified whereas specific drivers for certain regions suggest some level of continuous improvement e g reduced energy intensity in asia they are incapable of offsetting the effects of economic growth and energy use with the exception of africa most regions appear to have missed the low carbon economy opportunity provided by the 2008 2009 global financial crisis results suggest a lack of serious environmental effectiveness of regional policy portfolios aiming at reducing co2 emissions highly ambitious energy efficiency and renewable energy policies across all regions are immediately needed additionally absolute reductions in co2 emissions and energy use from fossil fuels are urgently required in rich regions if we are to align production and consumption patterns with maintaining global warming below the 2 c threshold

standard errors in event studies even if true abnormal returns are uncorrelated estimated abnormal returns are not this paper presents a simple formula for the variance of estimated cumulative abnormal re turns both returns and dummy variable procedures for estimating the standard error correctly taking account of both intertemporal and contemporaneous correlation of esti mated residuals are discussed they are then applied to an event study of post merger performance it is shown that ignoring either the intertemporal or contemporaneous correlation of residuals can result in significant underestimates of standard errors

energy decomposition analysis iea model versus other methods abstract in energy decomposition analysis the international energy agency iea model which is based on the laspeyres index method is included in a recent international collaborative initiative on energy indicators for sustainable development for possible adoption iaea 2005 energy indicators for sustainable development guidelines and methodology international atomic energy agency vienna www pub iaea org mtcd publications pdf pub1222 web pdf from an empirical analysis using the data of the united states we found that the residual term given by the iea model could be significant and that the estimates of the impacts of structure and intensity changes given by the model could be quite different from those given by other decomposition methods the residual term tends to be large when changes in structure and or energy intensity variables are significant since changes in these variables over time are generally larger in the developing countries than in the iea countries there is the question about whether the iea model is an appropriate decomposition method for the developing countries

the decomposition of co2 emissions from energy use in greece before and during the economic crisis and their decoupling from economic growth abstract greece recorded a significant decline in co 2 emissions from energy use from 2003 to 2013 accompanied by a reduction in energy consumption particularly during the economic recession this study attempts to identify the driving forces of co 2 emissions related to energy consumption through the use of the complete decomposition technique developed by jw sun the decomposition analysis focuses on the four factors responsible for co 2 emissions the carbon intensity effect the energy intensity effect the structural effect and the economic activity effect the analysis covers all the major productive sectors of the greek economy the study covers the period 2003 2013 and is divided into two subperiods 2003 2008 and 2008 2013 in order to assess changes in the contribution of the examined factors during the economic crisis 2008 2013 the analysis is extended to examine the decoupling relationship between co 2 emissions and economic growth in greece with the use of the decoupling index

decomposing road freight energy use in the united kingdom applying the techniques of decomposition analysis we estimate the relative contribution of ten variables termed key ratios plus gdp to the change in uk road freight energy use over the period 19892004 inclusive the results are best interpreted as an estimate of the percentage growth in energy consumption that would have resulted from the change in the relevant factor e g length of haul had the other factors remained unchanged the results demonstrate that the main factor contributing to the decoupling of uk road freight energy consumption from gdp was the decline in the value of domestically manufactured goods relative to gdp over the period 19892004 this largely offset the effect of increases in gdp on road freight energy consumption while the decline in domestic manufacturing was to some extent displaced by increases in imports the net effect of these supply factors together with shifts in the commodity mix has been to reduce uk road freight energy consumption by 30 1 the net effect on global carbon dioxide co2 emissions is likely to be somewhat less beneficial since many freight movements associated with the manufacture of imported goods have simply been displaced to other countries

correlation analysis of co 2 emissions material stocks and economic growth nexus evidence from chinese provinces abstract a better understanding of the economy material emissions nexus is fundamental in order to reveal the interactions between human development and the natural environment and more importantly to design integrated de carbonization and de materialization policies in this paper we conducted a decoupling analysis of fossil fuel induced co2 emissions and in use material stocks in infrastructure to economic growth at the provincial level in china and investigated the trilateral causal relationships among the three indicators the results show that the average elasticity of co2 emissions and material stocks to economic growth was smaller than 1 representing a status of relative decoupling however in many less developed provinces in central and western china we observed increasing trends of elasticity in the past three decades which suggest their economic growth became more tightly linked to co2 emissions and the accumulation of material stocks granger tests suggest that in the long run there existed a unidirectional causality running from co2 emissions economic growth and urbanization to material stocks in the short run a bi directional causality between co2 emissions and economic growth and a unidirectional causality from material stocks to co2 emissions were detected policy implications for the de carbonization and de materialization transition include enhancing renewable energy utilization upgrading industries to less carbon intensive ones developing compact cities prolonging the lifespan of infrastructure and strengthening the life cycle carbon management of infrastructure

comparisons of decoupling trends of global economic growth and energy consumption between developed and developing countries abstract the development of economy in developing countries is expected to contribute mostly to the growth of world energy consumption using environment impact gdp technology igt decoupling model we carry out a comparative study on the decoupling trends of economic growth and energy consumption for both developed and developing countries in past five decades 1965 2015 the results indicate that the decoupling indices of developed countries are superior to that of developing countries the specific performances are 1 the decoupling indices of developed countries are shown to be stable and tend to approximate absolute decoupling 2 the decoupling indices of developing countries fluctuate in the relative decoupling interval on this basis this research employs grey relational analysis gra to explore the reasons resulting in the difference of decoupling indices from the perspective of technical progress industrial structure and economic growth pattern the findings show that in developed countries technical progress factor exerts greatest influence on decoupling indices followed by industrial structure and economic growth pattern in developing countries industrial structure and economic growth pattern have greater impact on decoupling indices than technical progress based on research conclusion this research offers developing countries relevant policy suggestions for energy saving and emission reduction in the future

manufacturing energy use in eight oecd countries decomposing the impacts of changes in output industry structure and energy intensity this paper examines trends in manufacturing energy use in eight oecd countries decomposing the changes that occured between 1973 and 1987 into the effects of changes in aggregate manufacturing activity industry structure and energy intensities measured at the industry group level while manufacturing production grew in every country except the uk the rate of growth was variable from nation to nation structural change led to modest reductions in energy use in most countries although in norway structural change led to substantial growth in energy use the reduction in energy intensities was strikingly uniform across all nations ranging from 20 norway to 36 japan over the period of the analysis while other studies have used divisia decomposition techniques we use an alternative method based on laspeyres indices a comparison of the two techniques shows that they yield closely similar empirical results although the laspeyres approach is more easily interpreted while the interactions between changes in structure and intensity are arbitrarily assigned to the two factors by the divisia approach the lapeyres method yields interaction terms that explicitly account for such effects

decoupling of industrial energy consumption and co2 emissions in energy intensive industries in scandinavia as methodology the ex post analysis deserves more attention as a device to calibrate energy sector models this paper studies the impact of energy prices and taxes on energy efficiency and carbon emissions of ten industrial sectors in the three scandinavian countries a database with sector specific energy prices and taxes has been established which allows the analysis to take various price reductions and tax exemptions better into account a translog factor demand system estimation for a cross industry pooled model is explored and fixed effects across industries and time is estimated the findings here confirm recent analyses which indicate higher long term elasicities for industries than normally assumed in scandinavian energy sector models with the observations on differences in energy intensities among sectors and countries the findings allow for some optimism as to the opportunities for further decoupling between trends in gross value added carbon emissions and energy consumption

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

decomposition of aggregate carbon intensity for the manufacturing sector comparison of declining trends from 10 oecd countries for the period 1971 1991 abstract as with total energy consumption or aggregate energy intensity changes in aggregate carbon intensity may also be decomposed or attributed to changes in various components including fuel mix for electricity generation final energy mix sub sectoral economic activity and sub sectoral energy intensities the adaptive weighted divisia rolling base year index specification is applied to total carbon emissions from the manufacturing sector of 10 oecd countries for the period 1971 1991 declines in aggregate carbon intensity for these countries range from 70 and may be primarily attributed to decreases in energy intensity i e increases in the average factor productivity of energy however these declines in aggregate carbon intensity appear to have a complex linkage to increases in energy prices as well as changes in other determinants of gross industrial output

change in energy related co2 carbon dioxide emissions in portuguese tourism a decomposition analysis from 2000 to 2008 abstract tourism is an activity with great potential in portugal at a time of economic crisis tourism is seen as an opportunity to boost the economy and provide sustainable economic growth this strategic path based on tourism has to be accomplished in order to make better use of the economic advantages but at the same time respecting the environment and environmental goals to which portugal is committed so it becomes important to analyze what effects contribute more to emissions in this sector as well as which tourism subsectors are more responsible for the increase of emissions the objective of this work is to identify the effects in which co2 carbon dioxide emissions in tourism can be broken down and analyzed as well as their evolution and which of them has more importance in determining emissions for that in this study a decomposition technique based on logarithmic mean divisia index was used in the 2000 2008 period for five tourism subsectors in portugal in general tourism activity is the most important effect energy mix carbon intensity and energy intensity effects also proved important

china s changing energy intensity trend a decomposition analysis china experienced a dramatic decline in energy intensity from the onset of economic reform in the late 1970s until 2000 but since then the rate of decline slowed and energy intensity actually increased in 2003 most previous studies found that most of the decline was due to technological change but disagreed on the role of structural change to the best of our knowledge no decomposition study has investigated the role of inter fuel substitution in the decline in energy intensity or the causes of the rise in energy intensity since 2000 in this paper we use logarithmic mean divisia index lmdi techniques to decompose changes in energy intensity in the period 1980 2003 we find that 1 technological change is confirmed as the dominant contributor to the decline in energy intensity 2 structural change at the industry and sector sub industry level actually increased energy intensity over the period of 1980 2003 although the structural change at the industry level was very different in the 1980s and in the post 1990 period 3 structural change involving shifts of production between sub sectors however decreased overall energy intensity 4 the increase in energy intensity since 2000 is explained by negative technological progress 5 inter fuel substitution is found to contribute little to the changes in energy intensity

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

international trade policy in a model of unemployment and wage differentials the author examines the effects of import tariffs and export subsidies in a two sector model with sector specific wage differentials and an equilibrium level of unemployment in general such policies change both the composition and level of employment policies designed to attract workers to the high wage sector could also result in reduced employment and lower social welfare this could happen if the low wage sector is also the relatively labor intensive sector in such situations the optimal policy might entail protecting the low wage labor intensive sector i examine the effects of import tariffs and export subsidies in a two sector model with sector specific wage differentials and an equilibrium level of unemployment in general such policies change both the composition and level of employment policies designed to attract workers to the high wage sector could also result in reduced employment and lower social welfare this could happen if the low wage sector is also the relatively labour intensive sector in such situations the optimal policy might entail protecting the low wage labour intensive sector

how can chile move away from a high carbon economy abstract this paper quantitatively evaluates the performance of chile s co2 emissions between 1991 and 2013 using a complete decomposition technique to examine emissions and their components a decomposition analysis based on log mean divisia index method lmdi i was conducted six decomposition factors were considered carbon intensity effect ci res penetration effect res energy intensity effect ei economy structure effect es income effect yp and population effect p to know how these factors could influence each other in the future the innovative accounting approach iaa was used including forecast error variance decomposition and impulse response functions irfs these two methodologies allow us to identify the drivers of co2 emission changes in the past 1991 2013 test policy measures and learn how these drivers could influence each other in the future to evaluate whether the current measures meet the paris commitments the lmdi analysis results show that the energy intensity factor is the main compensating factor of chile s co2 emissions and the only effect with a clear trend to aid the economy s decoupling iaa and ifrs results react similarly and confirm that carbon intensity reacts to shocks more significantly in the short term the reaction to res has the same and opposite behavior to shocks in es and yp to disappear in the long term

jobs and chocolate samuelsonian surpluses in dynamic models of unemployment in dynamic models of unemployment in which the employed consume more than the unemployed workers are finitely lived and jobs are lasting employment transfers consumption from future generations to those currently alive resulting in a social surplus that is these transfers allow the current generation to consume more than its share of the output produced during its lifetime without the increased consumption coming at the expense of future generations moreover due to these intergenerational transfers the allocation that maximizes steady state output is pareto dominated by another feasible allocation with a higher level of steady state employment
