an analysis of the driving forces of energy related carbon dioxide emissions in china s industrial sector abstract both energy consumption and the growth of carbon dioxide co2 emissions in china are attributed to the industrial sector energy conservation and co2 emissions reduction in china s industrial sector is decisive for achieving a low carbon transition we analyze the change of energy related co2 emissions in china s industrial sector from 1991 to 2010 based on the logarithmic mean divisia index lmdi method results indicate that industrial activity is the major factor that contributes to the increase of industrial co2 emissions while energy intensity is the major contributor to the decrease of co2 emissions industry size shows a varying trend interchanging intervals of growth along the study period moreover both energy mix and carbon intensity of energy use have negative effects on the increase of co2 emissions the cointegration method is adopted to further explore determinants of co2 emissions in china s industrial sector results show that there exists a long run relationship between industrial co2 emissions and affecting factors such as co2 emissions per unit of energy consumption industrial value added labor productivity and fossil fuel consumption china s industrial co2 emissions are mainly attributed to the coal dominated energy structure policy suggestions are thus provided to reduce industrial co2 emissions in china

a dynamic approach to the environmental kuznets curve hypothesis abstract the environmental kuznets curve ekc hypothesis states that pollution levels increase as a country develops but begin to decrease as rising incomes pass beyond a turning point in ekc analyses the relationship between environmental degradation and income is usually expressed as a quadratic function with the turning point occurring at a maximum pollution level other explanatory variables have been included in these models but income regularly has had the most significant effect on indicators of environmental quality one variable consistently omitted in these relationships is the price of energy this paper analyzes previous models to illustrate the importance of prices in these models and then includes prices in an econometric ekc framework testing energy income and co2 income relationships these long run price income models find that income is no longer the most relevant indicator of environmental quality or energy demand indeed we find no significant evidence for the existence of an ekc within the range of current incomes for energy in the presence of price and trade variables

economic growth and pollutant emissions in tunisia an empirical analysis of the environmental kuznets curve abstract this paper investigates the relationship between economic growth and pollutant emissions for a small and open developing country tunisia during the period 1961 2004 the investigation is made on the basis of the environmental kuznets curve hypothesis using time series data and cointegration analysis carbon dioxide co 2 and sulfur dioxide so 2 are used as the environmental indicators and gdp as the economic indicator our results show that there is a long run cointegrating relationship between the per capita emissions of two pollutants and the per capita gdp an inverted u relationship between so 2 emissions and gdp has been found with income turning point approximately equals to 1200 constant 2000 prices or to 3700 in ppp constant 2000 prices however a monotonically increasing relationship with gdp is found more appropriate for co 2 emissions furthermore the causality results show that the relationship between income and pollution in tunisia is one of unidirectional causality with income causing environmental changes and not vice versa both in the short run and long run this implies that an emission reduction policies and more investment in pollution abatement expense will not hurt economic growth it could be a feasible policy tool for tunisia to achieve its sustainable growth in the long run

environmental kuznets curve hypothesis in pakistan cointegration and granger causality abstract the paper is an effort to fill the gap in the energy literature with a comprehensive country study of pakistan we investigate the relationship between co2 emissions energy consumption economic growth and trade openness in pakistan over the period of 1971 2009 bounds test for cointegration and granger causality approach are employed for the empirical analysis the result suggests that there exists a long run relationship among the variables and the environmental kuznets curve ekc hypothesis is supported the significant existence of ekc shows the country s effort to condense co2 emissions and indicates certain achievement of controlling environmental degradation in pakistan furthermore we find a one way causal relationship running from economic growth to co2 emissions energy consumption increases co2 emissions both in the short and long runs trade openness reduces co2 emissions in the long run but it is insignificant in the short run in addition the change of co2 emissions from short run to the long span of time is corrected by about 10 yearly

environmental kuznets curve in romania and the role of energy consumption abstract the aim of present study is to probe the dynamic relationship between economic growth energy consumption and co 2 emissions for period of 1980 2010 in case of romania in doing so ardl bounds testing approach is applied to investigate the long run cointegration between these variables our results confirm long run relationship between economic growth energy consumption and energy pollutants the empirical evidence reveals that environmental kuznets curve ekc is found both in long and short runs in romania further energy consumption is major contributor to energy pollutants democratic regime shows her significant contribution to decline co 2 emissions through effective implementation of economic policies and financial development improves environment i e reduces co 2 emissions by redirecting the resources to environment friendly projects

china s energy consumption and sustainable development comparative evidence from gdp and genuine savings this paper employs the structural vector autoregressions framework and the generalized impulse response function to study the long term dynamic relation between china s energy consumption and sustainable economic growth in addition to the conventional economic indicators gdp growth rates genuine savings rates are particularly examined to indicate sustainable economic development results show that the high elasticity of energy consumption dramatically undermines the capacity of china s sustainability in terms of reducing genuine savings rates we also use variance decomposition to calculate relative variance contribution rates in order to identify the most important factor affecting gdp growth as well as genuine savings rates the analysis finds that clean and renewable energy increase the country s genuine savings significantly that is renewable energy consumption promotes sustainable development for both natural and economic societies however increase in traditional solid energy consumption is more likely to benefit only the growth of gdp

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

energy consumption real income and temporal causality results from a multi country study based on cointegration and error correction modelling techniques abstract unlike previous studies on the causal relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multivariate cointegration tests preceded by various unit root or non stationarity tests we test for cointegration between total energy consumption and real income of six asian economies india pakistan malaysia singapore indonesia and the philippines non rejection of cointegration between variables rules out granger non causality and imples at least one way of granger causality either unidirectional or bidirectionial secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample granger exogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total impact of an unanticipated shock to each of the variables beyond the sample period into proportions attributable to shocks in the other variables including its own in the bivariate system results based on these tools of methodology indicate that while all pair wise relationships shared common univariate integrational properties only relationships for three countries india pakistan and indonesia were cointegrated for these countries temporal causality results were mixed with unidirectional causality from energy to income for india exactly the reverse for indonesia and mutual causality for pakistan the vdcs were not inconsistent with these results and provided us with an additional insight as to the relatively more dominant direction of causation in pakistan simple bivariate vector autoregressive models for the three non cointegrated systems did not indicate any direction of causality significantly in either direction

energy consumption and gdp causality relationship in g 7 countries and emerging markets abstract the causality relationship between energy consumption and income is a well studied topic in energy economics this paper studies the time series properties of energy consumption and gdp and reexamines the causality relationship between the two series in the top 10 emerging markets excluding china due to lack of data and g 7 countries we discover bi directional causality in argentina causality running from gdp to energy consumption in italy and korea and from energy consumption to gdp in turkey france germany and japan hence energy conservation may harm economic growth in the last four countries

an econometric study of co2 emissions energy consumption income and foreign trade in turkey abstract this study attempts to empirically examine the dynamic causal relationships between carbon emissions energy consumption income and foreign trade in the case of turkey using the time series data for the period 1960 2005 this research tests the interrelationship between the variables using the bounds testing to cointegration procedure the bounds test results indicate that there exist two forms of long run relationships between the variables in the case of first form of long run relationship carbon emissions are determined by energy consumption income and foreign trade in the case of second long run relationship income is determined by carbon emissions energy consumption and foreign trade an augmented form of granger causality analysis is conducted amongst the variables the long run relationship of co2 emissions energy consumption income and foreign trade equation is also checked for the parameter stability the empirical results suggest that income is the most significant variable in explaining the carbon emissions in turkey which is followed by energy consumption and foreign trade moreover there exists a stable carbon emissions function the results also provide important policy recommendations

an investigation of co integration and causality between energy consumption and economic activity in taiwan applying hsiao a version of the granger causality method this paper examines the causality between energy and gnp and energy and employment by applying recently developed techniques of co integration and hsiao s version of the granger causality to taiwanese data for the 1955 1993 period the phillips perron tests reveal that the series with the exception of gnp are not stationary and therefore differencing is performed to secure stationarity the study finds causality running from gdp to energy consumption without feedback in taiwan it is also found that causality runs from gdp to energy but not vice versa

how economic growth affects emissions an investigation of the environmental kuznets curve in portuguese and spanish economic activity sectors abstract it is a disquieting reality that increased economic growth for many years now in the western world is at odds with environmental degradation in this paper the relationship between economic growth and environmental variables is analyzed under two non linear specifications a quadratic and a cubic specification the study is conducted for portugal and spain in the period 1975 2012 using data for 13 sectors gva is used as proxy for income while energy use and carbon dioxide account for environmental degradation there is evidence for an inverted u shaped ekc however there are also other inverted n shaped functions that explain the relationship between economic growth and emissions altogether empirical results do indicate particular differences between portuguese and spanish sectors the results are of interest not only for researchers but also for policy makers political mitigation measures are also analyzed

stoking the fires co2 emissions and economic growth abstract we examine the relationship between economic development and carbon dioxide emissions a greenhouse gas central to global warming predictions estimates derived from global panel data suggest a diminishing marginal propensity to emit mpe carbon dioxide as gdp per capita rises despite this global carbon dioxide emissions growth will continue at 1 8 percent per annum for the foreseeable future a result that is not sensitive to average output growth instead emissions growth continues because output and population will grow most rapidly in lower income nations with high mpes this latter feature emphasizes the distributional consequences of policies to reduce emissions

economic growth and emissions reconsidering the empirical basis of environmental kuznets curves abstract recent empirical research indicates that certain types of emissions follow an inverted u or environmental kuznets curve ekc as income grows this regularity has been interpreted as a possible de linking of economic growth and patterns of certain pollutants for developed economies in this paper the empirical basis of this result is investigated by considering some statistical particularities of the various ekc studies performed it is argued that the inverted u relationship between income and emissions estimated from panel data need not hold for specific individual countries over time based on insights from intensity of use analysis in resource economics an alternative growth model is specified and estimated for three types of emissions co2 nox and so2 in four countries netherlands uk usa and western germany it is found that the time patterns of these emissions correlate positively with economic growth and that emission reductions may have been achieved as a result of structural and technological changes in the economy sustainable growth is defined as the rate of economic growth that does not lead to growth in emissions its rate is calculated for each type of emission and country based on estimated parameter values the resulting indicators reflect a balance between the positive influence of growth and negative influence of structural change and technological progress on emission levels

reexamining the empirical evidence for an environmental kuznets curve this paper uses an updated and revised panel data set on ambient air pollution in cities worldwide to examine the robustness of the evidence for the existence of an inverted u shaped relationship between national income and pollution we test the sensitivity of the pollution income relationship to functional forms to additional covariates and to changes in the nations cities and years sampled we find that the results are highly sensitive to these changes and conclude that there is little empirical support for an inverted u shaped relationship between several important air pollutants and national income in these data

energy conservation and emissions reduction in china progress and prospective abstract energy conservation ec has been taken as basic state policy in china for more than 20 years and china achieves 3 9 annual energy saving from 1980 to 2005 in 2006 china central government firstly set up a binding target of reducing gdp energy intensity by 20 in its 11th five year plan fyp at the end of 2010 19 1 reduction in energy intensity has been achieved which is 95 of the target and means 608 million tons stand coal equivalence sce saved 1510 million tons co 2 emission reduced 300 billion rmb saving in energy bill and vast saving in infrastructure investment this paper is systematical review and prospective analysis on energy policy issue in china review on policy evolution and progress of ec and emission reduction er in china during the 11th fyp periods is presented in detail outlook of energy demand and supply into 2050 is presented and the roadmap to realize sustainable energy development is drafted to set the framing constraints for china s energy policy options rationality and feasibility analysis on newly formulated 12th fyp ec and er target is also addressed then lessons from the 11th fyp periods are drawn and factors underlying and limiting the policy formulation and implementation are discussed in details to probe the policy predicament and solutions finally policy suggestions are proposed for long term successful implementation of ec and er in china

is there an environmental kuznets curve for deforestation abstract this paper examines the relationship between deforestation and gross domestic product gdp per capita in particular whether an inverted u relationship indicative of worsening then improving deforestation exists between them we note that previous work has used models with restrictive assumptions and recommend a more flexible random coefficients specification which allows for a greater degree of cross country heterogeneity empirical results using data for 76 developing countries between 1961 1992 suggest that the inverted u shaped relationship observed in other studies does not appear to be an empirical regularity with our less restrictive specification statistical tests indicate that this specification is supported by the data we argue that such results are not surprising in view of the wide diversity of physical and social characteristics that exist across countries

relationship between level of economic development and motorcycle and car ownerships and their impacts on fuel consumption and greenhouse gas emission in thailand abstract an increase in road vehicles secondary to economic development has strongly pushed up energy demand and adversely impact the environment by the emission of greenhouse gases and pollutants this paper aims to analyse the relationship between motorcycle and car ownerships and level of economic development in thailand in addition an overall private vehicle ownership which is a sum of both types of private vehicle ownership is also studied an understanding of these relationships due to the economic development is a key knowledge for the sustainable transport policy in the future the results of this study revealed that at the early stage of economic development of developing countries like thailand the number of motorcycles predominates over private cars economic development strongly affects the ownership of private vehicles in two ways 1 overall private vehicle ownerships increase as the income levels grow and 2 after personal income grows up to a certain level people will shift from motorcycle to car ownerships for their prestige convenience comfort and safety because of continuing economic development and population growth the expected increase in overall private vehicle ownership is projected to push up the total private vehicle stock of thailand in the year 2050 to about twice of the present level this will drive fuel demands in 2050 to about 2 4 times and the greenhouse gases ghg emission to about 2 5 times of the current levels hence policy makers in developing countries should not overlook the impacts on the consequences of increasing overall private vehicle stock in the near future the best and most appropriate policies should be given to the development of public transport as the first priority rather than the traditional one which gives highest priority to traffic mobility of private vehicles by road transport neglecting the effectiveness of passengers mobility of the public transport in addition policies to promote high efficiency vehicle technologies particularly for motorcycles should also be taken into consideration particularly for a low income country due to a high share of the motorcycles in the overall private vehicle stock

economic growth and atmospheric pollution in spain discussing the environmental kuznets curve hypothesis abstract the environmental kuznets curve ekc hypothesis posits an inverted u relationship between environmental pressure and per capita income recent research has examined this hypothesis for different pollutants in different countries despite certain empirical evidence showing that some specific environmental pressures have diminished in developed countries the hypothesis could not be generalized to the global relationship between economy and environment at all in this article we contribute to this debate analyzing the trends of annual emission flux of six atmospheric pollutants in spain the study presents evidence that there is not any correlation between higher income level and smaller emissions except for so2 whose evolution might be compatible with the ekc hypothesis the authors argue that the relationship between income level and diverse types of emissions depends on many factors thus it cannot be thought that economic growth by itself will solve environmental problems

the demand for gasoline in south africa an empirical analysis using co integration techniques abstract using the recently developed autoregressive distributed lag ardl bound testing approach to co integration suggested by pesaran et al pesaran m h shin y smith r j bounds testing approaches to the analysis of level relationships journal of applied econometrics 2001 16 3 289 326 we empirically analyzed the long run relationship among the variables in the aggregate gasoline demand function over the period 1978 2005 our study confirms the existence of a co integrating relationship the estimated price and income elasticities of 0 47 and 0 36 imply that gasoline demand in south africa is price and income inelastic

on the causal nexus of road transport co2 emissions and macroeconomic variables in tunisia evidence from combined cointegration tests abstract this paper investigates the causal relationship between road transportation energy consumption fuel prices transport sector value added and co2 emissions in tunisia for the period of 1980 2012 we apply the newly developed combined cointegration test proposed by bayer c hanck c combining non cointegration tests j time ser anal 2013 34 1 83 95 and the ardl bounds testing approach to cointegration for establishing the existence of long run relationship in presence of structural breaks the direction of causality between these variables is determined via vector error correction model vecm our empirical exercise reveals that cointegration is present energy consumption adds in co2 emissions fuel prices decline co2 emissions road infrastructure boosts co2 emissions transport value added also increases co2 emissions the causality analysis indicates the bidirectional casual relationship between energy consumption and co2 emissions road infrastructure causes co2 emissions and similar is true from opposite side in granger sense the bidirectional causality is also found between transport value added and co2 emissions fuel prices cause co2 emissions energy consumption road infrastructure and transport value added in granger sense this paper provides new insights to policy makers for designing a comprehensive energy transport and environment policies for sustainable economic growth in long run

a household level environmental kuznets curve abstract richer households may create more vehicle emissions because they own more vehicles and drive more poorer households may pollute more because they use high polluting vintages and maintain them less well this paper uses 1993 california vehicle microdata to show that there is a kuznets u shaped hydrocarbon emissions relation

examining carbon emissions economic growth nexus for india a multivariate cointegration approach abstract the study probes cointegration and causality between carbon emissions and economic growth for india using ardl bounds testing approach complemented by johansen juselius maximum likelihood procedure in a multivariate framework by incorporating energy supply investment and employment for time span 1971 2006 the study fails to establish long run equilibrium relationship and long term causality between carbon emissions and economic growth however there exists a bi directional short run causality between the two hence in the short run any effort to reduce carbon emissions could lead to a fall in the national income this study also establishes unidirectional short run causality running from economic growth to energy supply and energy supply to carbon emissions the absence of causality running from energy supply to economic growth implies that in india energy conservation and energy efficiency measures can be implemented to minimize the wastage of energy across value chain such measures would narrow energy demand supply gap absence of long run causality between carbon emissions and economic growth implies that in the long run focus should be given on harnessing energy from clean sources to curb carbon emissions which would not affect the country s economic growth

a multivariate cointegration analysis of the role of energy in the us macroeconomy abstract this paper extends my previous analysis of the causal relationship of gdp and energy use in the usa in the post war period a majority of the relevant variables are integrated justifying a cointegration analysis the results show that cointegration does occur and that energy input cannot be excluded from the cointegration space the results are plausible in terms of macroeconomic dynamics the results are similar to my previous granger causality results and contradict claims in the literature based on bivariate models that there is no cointegration between energy and output

energy consumption and gdp in tunisia cointegration and causality analysis abstract in this paper the johansen cointegration technique is used to examine the causal relationship between per capita energy consumption pcec and per capita gross domestic product pcgdp for tunisia during the 1971 2004 period in order to test for granger causality in the presence of cointegration among the variables a vector error correction model vecm is used instead of a vector autoregressive var model our estimation results indicate that the pcgdp and pcec for tunisia are related by one cointegrating vector and that there is a long run bi directional causal relationship between the two series and a short run unidirectional causality from energy to gross domestic product gdp the source of causation in the long run is found to be the error correction terms in both directions hence an important policy implication resulting from this analysis is that energy can be considered as a limiting factor to gdp growth in tunisia conclusions for tunisia may also be relevant for a number of countries that have to go through a similar development path of increasing pressure on already scarce energy resources

energy consumption and economic growth the case of oil exporting countries this paper examines the causal relationship between the per capita energy consumption and the per capita gdp in a panel of 11 selected oil exporting countries by using panel unit root tests and panel cointegration analysis the results show a unidirectional strong causality from economic growth to energy consumption for the oil exporting countries the findings have practical policy implications for decision makers in the area of macroeconomic planning in most major oil exporting countries government policies keep domestic prices bellow free market level resulting in high levels of domestic energy consumption the results imply that the energy conservation through reforming energy price policies has no damaging repercussions on economic growth for this group of countries

causality between energy consumption and economic growth in india a note on conflicting results abstract this note examines the different direction of causal relation between energy consumption and economic growth in india applying engle granger cointegration approach combined with the standard granger causality test on indian data for the period 1950 1996 we find that bi directional causality exists between energy consumption and economic growth further we apply johansen multivariate cointegration technique on the different set of variables the same direction of causality exists between energy consumption and economic growth this is different from the results obtained in earlier studies

estimating the effect of urban density on fuel demand much of the empirical literature on fuel demand presents estimates derived from national data which do not permit any explicit consideration of the spatial structure of the economy intuitively we would expect the degree of spatial concentration of activities to have a strong link with transport fuel consumption the present paper addresses this theme by estimating a fuel demand model for urban areas to provide a direct estimate of the elasticity of demand with respect to urban density fuel demand per capita is decomposed into car stock per capita fuel consumption per kilometre and annual distance driven per car per year urban density is found to affect fuel consumption mostly through variations in the car stock and in the distances travelled rather than through fuel consumption per kilometre

energy consumption employment output and temporal causality evidence from taiwan based on cointegration and error correction modelling techniques in this study a cointegration analysis and a vector autoregressive model var are used to examine the causal relationships among energy consumption employment and output for taiwan over the period january 1982 to november 1997 johansen 1988 and johansen and juselius 1990 cointegration test result indicates these three variables are cointegrated with one cointegrating vector the results from granger causality tests based on vector error correction models vecm suggest bidirectional grange causality for employment output and employment energy consumption but only unidirectional causality running from energy consumption to output furthermore the impulse responses and variance decompositions are also incorporated into the analysis the results from impulsive response and variance decomposition analysis tell similar stories energy consumption appears to have led to output growth in taiwan over this period the policy implication of this finding is that energy conservation will restrain the outpu

the effects of child bearing on married women s labor supply and earnings using twin births as a natural experiment we use exogenous variations in fertility due to twin births to measure the impact of an unplanned child on married women s labor supply and earnings although the overall effects of an unplanned birth on labor supply are small we find significant effects in the years immediately following the unplanned birth especially in 1970 we estimate that declining fertility explains between 6 and 13 percent of the increase in married women s labor supply between 1970 and 1980 twin births are also associated with a substantial short run loss in earnings this effect persists longer than the labor supply effects though it does eventually disappear

energy consumption carbon emissions and economic growth in china abstract this paper investigates the existence and direction of granger causality between economic growth energy consumption and carbon emissions in china applying a multivariate model of economic growth energy use carbon emissions capital and urban population empirical results for china over the period 1960 2007 suggest a unidirectional granger causality running from gdp to energy consumption and a unidirectional granger causality running from energy consumption to carbon emissions in the long run evidence shows that neither carbon emissions nor energy consumption leads economic growth therefore the government of china can purse conservative energy policy and carbon emissions reduction policy in the long run without impeding economic growth

the relationship between energy consumption energy prices and economic growth time series evidence from asian developing countries this paper estimates the causal relationships between energy consumption and income for india indonesia the philippines and thailand using cointegration and error correction modelling techniques the results indicate that in the short run unidirectional granger causality runs from energy to income for india and indonesia while bidirectional granger causality runs from energy to income for thailand and the philippines in the case of thailand and the philippines energy income and prices are mutually causal the study results do not support the view that energy and income are neutral with respect to each other with the exception of indonesia and india where neutrality is observed in the short run c 2000 elsevier science b v all rights reserved jel classifications c22 q43 q48

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

energy consumption and gdp in turkey is there a co integration relationship energy consumption and gdp are expected to grow by 5 9 and 7 annually until 2025 in turkey this paper tries to unfold the linkage between energy consumption and gdp by undertaking a co integration analysis for turkey with annual data over the period 1970 2003 the analysis shows that energy consumption and gdp are co integrated this means that there is a possibly bi directional causality relationship between the two we establish that there is a unidirectional causality running from gdp to energy consumption indicating that energy saving would not harm economic growth in turkey in addition we find that energy consumption keeps on growing as long as the economy grows in turkey

co2 emissions energy consumption and output in france abstract this paper examines the dynamic causal relationships between pollutant emissions energy consumption and output for france using cointegration and vector error correction modelling techniques we argue that these variables are strongly inter related and therefore their relationship must be examined using an integrated framework the results provide evidence for the existence of a fairly robust long run relationship between these variables for the period 1960 2000 the causality results support the argument that economic growth exerts a causal influence on growth of energy use and growth of pollution in the long run the results also point to a uni directional causality running from growth of energy use to output growth in the short run

is there an environmental kuznets curve for sulfur abstract most existing estimates of the environmental kuznets curve ekc for sulfur which use samples of mainly high income countries indicate a maximum emissions turning point at middle to lower high income levels of gdp per capita we use a larger and more globally representative sample than previous sulfur ekc studies we find that sulfur emissions per capita are a monotonic function of income per capita when we use a global sample and an inverted u shape function of income when we use a sample of high income countries a model estimated in first differences results in a monotonic ekc when estimated with both high income and global samples reductions in emissions are time related rather than income related

energy consumption income and carbon emissions in the united states abstract this paper investigates the effect of energy consumption and output on carbon emissions in the united states earlier research focused on testing the existence and or shape of an environmental kuznets curve without taking energy consumption into account we investigate the granger causality relationship between income energy consumption and carbon emissions including labor and gross fixed capital formation in the model we find that income does not granger cause carbon emissions in the us in the long run but energy use does hence income growth by itself may not become a solution to environmental problems
