causalities between co2 electricity and other energy variables during phase i and phase ii of the eu ets the topic of this article is the analysis of the interplay between daily carbon electricity and gas price data with the european union emission trading system eu ets for co2 emissions in a first step we have performed granger causality tests for phase i of the eu ets january 2005 until december 2007 and the first year of phase ii of the eu ets 2008 the analysis includes both spot and forward markets given the close interactions between the two sets of markets the results show that during phase i coal and gas prices through the clean dark and spark spread impacted co2 futures prices which in return granger caused electricity prices during the first year of the phase ii the short run rent capture theory in which electricity prices granger cause co2 prices prevailed on the basis of the qualitative results of the granger causality tests we obtained the formulation testable equations for quantitative analysis standard ols regressions yielded statistically robust and theoretically coherent results

the empirical analysis of the determinants for environmental technological change a research agenda abstract technological change is usually considered a necessary albeit not sufficient condition for a transition to sustainability however the empirical analysis of the determinants to environmental technological change has not received too much attention in the environmental ecological economics literature and many open questions remain in this context based on a careful review of the literature this paper argues that further analysis should address several issues at different levels i e regarding the conceptual framework the thematic scope of the studies some methodological issues and other aspects related to the environmental policy variable first an integrated conceptual framework which takes into account the interplay between relevant variables influencing environmental technological change i e factors internal and external to the firm and characteristics of the environmental technologies and all the stages of this process with a greater emphasis on the invention stage should be developed other aspects should then be tackled including a focus on several themes i e a greater attention to cross sectoral technologies the barriers to different types of environmental technologies the international dimension of environmental technological change and environmental technological change in small and medium size enterprises methodological issues combination of case studies and econometric modelling and several issues related to the environmental policy variable

interaction among china carbon emission trading markets nonlinear granger causality and time varying effect abstract china makes great efforts to reduce carbon emissions and mitigate global greenhouse gas in order to identify the interaction among china cet markets this paper comprehensively investigates nonlinear granger causality and time varying effect in markets by using the hiemstra and jones hj test diks and panchenko dp test and time varying parameter structure vector autoregressive tvp svar model the empirical analysis has demonstrated china major cet markets significantly bidirectional nonlinear granger cause each other as to time varying effect we have obtained convincing findings that time varying impulse responses are among china major cet markets in the short term specifically guangdong hubei and shenzhen cet markets are time varying co movement negatively or positively related to each other over time implying there are deep bases for china national cet market construction furthermore the specific time point impulse effects support our discoveries in time varying impulse responses

government ownership of banks institutions and economic growth we present new cross country evidence that reveals that during 1995 2007 government ownership of banks has been robustly associated with higher long run growth rates we also show that previous results suggesting that government ownership of banks is associated with lower long run growth rates are not robust to conditioning on more fundamental determinants of economic growth

the innovation impact of the eu emission trading system findings of company case studies in the german power sector abstract this paper provides a detailed analysis of how the european emission trading system eu ets as the core climate policy instrument of the european union has impacted innovation towards this end we investigate the impact of the eu ets on research development and demonstration rd d adoption and organizational change in doing so we pay particular attention to the relative influences of context factors policy mix market factors and public acceptance and firm characteristics value chain position technology portfolio size and vision empirically our qualitative analysis is based on multiple case studies with 19 power generators technology providers and project developers in the german power sector which were conducted in 2008 09 we find that the innovation impact of the eu ets has remained limited so far because of the scheme s initial lack of stringency and predictability and the relatively greater importance of context factors additionally the impact varies significantly across technologies firms and innovation dimensions and is most pronounced for rd d on carbon capture technologies and organizational changes our analysis suggests that the eu ets on its own may not provide sufficient incentives for fundamental changes in corporate innovation activities at a level which ensures political long term targets can be achieved

does craigslist reduce waste evidence from california and florida abstract there is much discussion but little research on the environmental impacts of online platforms associated with the sharing economy economic theory suggests that falling transaction costs in secondhand markets increase incentives for people to exchange rather than discard used goods this paper uses difference in difference methods to estimate craigslist s effect on solid waste by exploiting a natural experiment in how the platform expanded across california and florida the econometric results suggest that craigslist reduced daily per capita solid waste generation by about one third of a pound though the estimates are not very precise a plausibility analysis of the weight of items posted on craigslist concludes that the 200 million annual for sale posts created by californians and floridians can reasonably account for waste reductions of roughly this magnitude

exploring the price dynamics of co2 emissions allowances in china s emissions trading scheme pilots establishing regional emissions trading scheme pilots in china is a newly transformative and explorative practice in this paper we examine the spot price dynamics asymmetric clustering and regime switching behaviors of co2 emissions allowances in the new china wide emissions trading scheme cets pilots using ar garch ar tarch and mrs ar garch models the regional ets pilots design in china vary widely in their coverage thresholds sector coverage emissions allocation and caps setting methods market trading rules and price stabilization provisions our empirical results indicate that the spot prices of regional emissions allowances exhibit significant dynamic behaviors asymmetric leverage effects and regime switching behaviors in the entire period considered previous market overreactions in the beijing tianjin and guangdong pilots have stronger price clustering effects on future conditional variances than do the shanghai and hubei pilots unexpected market shocks and greater persistence in the beijing tianjin and guangdong ets pilots display stronger market volatility and higher market risks and their asymmetric leverage effects display a decreasing trend in the volatility of the bea tjea and gdea prices the bea and shea prices exhibit significant regime switching behaviors price jumps and higher volatility in addition the changes in the regime switching phases are often related to the political mechanism design and the fundamental market factors those empirical results are beneficial for government decision makers and market participants to strengthen risk management strategies support emission related investment decisions and optimize co benefits of alternative energy environmental policies

environmental policies and innovation a knowledge based perspective on cooperative approaches the purpose of this article is to analyse to growing interest in the field of the environment for new cooperative approcahes that make use of negotiated instruments such as voluntary agreements using an interpretation framework that puts the emphasis on collective learning and monitoring devices we highlight the value of this type of approach in situations of great uncertainty where a coordinated process of innovation is required to achieve ambitious environmental targets the implementation of this theoretical approach in the end of life vehicles elv case which has been the subject of several voluntary agreements in europe offers a fuller understanding of the characteristics and driving forces of the collective innovation process in action as well as the obstacles that have still to be overcome in particular we explain why monitoring of innovation by the authorities focusing on coordination mechanisms is a crucial issue on which further research should be carried out

an equilibrium model of consumer energy choice using a personal carbon trading scheme based on allowance price abstract changes in consumer behavior due to a personal carbon trading pct scheme are theoretically attractive yet untested in practice in this paper simulations on the basis of an equilibrium model are used to examine the effects of carbon allowance prices on energy use choice under a particular pct scheme it is shown that the equilibrium price of allowances would emerge under the pct scheme considered here further analyses indicate that the quantity of energy consumption under pct is a nonlinear function of the allowance price with a sharp kink at the point of equilibrium when the allowance price is below the equilibrium price consumers would prefer higher carbon energy in contrast when the allowance price is above the equilibrium price consumers would choose lower carbon energy however when the allowance price equals the equilibrium value consumers would purchase lower carbon energy and higher carbon energy simultaneously furthermore it is shown that the initial allowance allocation could also affect energy use choice on the basis of these results one of the main implications is that the allowance price should exceed the breakeven price to stimulate consumers to switch to green energy and progressively live a low carbon lifestyle

the market for tradable ghg permits under the kyoto protocol a survey of model studies abstract this paper gathers results from 25 models of the market for tradable greenhouse gas ghg emission permits under the kyoto protocol due to diverging projections of emissions growth and different modeling approaches the model results differ substantially the average market volume is approximately 17 and 33 billion usd under global trading and annex b trading respectively including non carbon ghg lowers compliance costs and permit prices in the absence of the us permit demand roughly equals hot air from the former soviet union these countries can increase their revenues from selling permits by restricting supply which raises the permit price

the response of the beijing carbon emissions allowance price bjc to macroeconomic and energy price indices in 2013 china opened pilot carbon emission trading markets in seven provinces where carbon emission allowances have now been traded for more than two years in this paper we employ a structural var model and the price of the beijing carbon emission allowance to study the dynamic relationships among the price of the carbon emission allowance economic development and the price of energy this paper s data cover the period from april 2 2014 to november 6 2015 this paper provides information that will be helpful to both investors and governmental policy makers the results show that 1 an increase of one standard deviation in the coal price leads to an initial increase of approximately 0 1 in the beijing carbon price after 2 days there is a decrease of less than 0 1 and the price gradually increases by approximately 0 1 after 30 days 2 the price of the beijing carbon emission allowance is mainly affected by its own historical price 3 the beijing carbon emission allowance price crude oil price natural gas price and economic development have positive albeit non significant correlations

an empirical analysis of energy cost pass through to co2 emission prices abstract we use the nonlinear autoregressive distributed lag nardl model to analyze the asymmetric and nonlinear pass through effects of changes in crude oil prices natural gas prices coal prices and electricity prices on the co 2 emission allowance prices we find that i the crude oil prices have a long run negative and asymmetric effect on the co 2 allowance prices ii the decreases in the coal prices have a stronger impact on the carbon prices in the short run than the increases iii the natural gas prices and electricity prices have a symmetric effect on the carbon prices but this effect is negative for the former and positive for the latter these findings are robust when using both monthly and daily data and when considering bivariate and multivariate models

price discovery and volatility spillovers in the european union emissions trading scheme a high frequency analysis abstract this paper models the relationship of european union allowance spot and futures prices within the second commitment period of the european union emissions trading scheme based on high frequency data we analyze the transmission of information in first and second conditional moments to reveal long run price discovery we compute common factor weights of schwarz and szakmary 1994 and information shares of hasbrouck 1995 based on estimated coefficients of a vecm to analyze the short run dynamics we perform granger causality tests we identify the futures market to be the leader of the long run price discovery process whereas the informational role of the futures market increases over time in addition we employ a version of the ueccc garch model as introduced by conrad and karanasos 2010 to analyze the volatility transmission structure the volatility analysis indicates a close relationship between the volatility dynamics of both markets whereas in particular we observe spillovers from the futures to the spot market as a whole the investigation reveals that the futures market incorporates information first and then transfers the information to the spot market

evaluating remanufacturing industry of china using an improved grey fixed weight clustering method a case of jiangsu province abstract remanufacturing industry can solve the issues of resource depletion and environment deterioration by reducing consumptions of raw materials and minimizing emissions of wastes it has been strongly promoted by chinese government in recent years however its current development situation has been unsatisfactory all the time the aim of this paper is to evaluate development level of remanufacturing industry of china and point out future directions of industrial improvement to achieve the above objective this paper establishes an evaluation index system of remanufacturing industry and puts forward an improved grey fixed weight clustering method which is suitable for assessing remanufacturing industry then taking jiangsu province of china as a practical case this method is used to evaluate its remanufacturing industry and identify rank order of improvement measures for each city research results show that overall development level of remanufacturing industry is still low and development unbalance is remarkable two more important findings are as follows the first is that rank orders of improvement measures for all cities are different from each other and decision maker should adopt differentiated industrial policies and improvement measures the second is that the cities which belong to the 2nd and 3rd grey class should paid more attention to improvement measures for four evaluation sub indices annual sale of remanufacturing industry total assets of remanufacturing enterprise total investment of under construction and total number of research institution and university participated in remanufacturing the major contribution of this study is to offer an effective decision making approach for evaluation of remanufacturing industry it helps in classifying development levels of remanufacturing industry in different cities and providing decision makers with a scientific basis for adopting appropriate industrial policies and improvement measures which will efficiently enhance remanufacturing industry in the future

time varying correlations in oil gas and co2 prices an application using bekk ccc and dcc mgarch models previous literature has identified oil and gas prices as being the main drivers of co2 prices in a univariate generalized autoregressive conditional heteroscedasticity garch econometric framework alberola et al 2008 oberndorfer 2009 by contrast we argue in this article that the interrelationships between energy and emissions markets shall be modelled in a vector autoregressive var and multivariate garch mgarch framework so as to reflect the dynamics of the correlations between the oil gas and co2 variables overtime using the baba engle kraft kroner bekk constant conditional correlation ccc and dynamic conditional correlation mgarch dcc mgarch models on daily data from april 2005 to december 2008 we highlight significant own volatility cross volatility spillovers and own persistent volatility effects for nearly all markets indicating the presence of strong autoregressive conditional heteroscedasticity arch and garch effects besides we provide strong empirical evidence of tim

income risk of eu coal fired power plants after kyoto coal fired power plants enjoy a significant advantage relative to gas plants in terms of cheaper fuel cost this advantage may erode or turn into disadvantage depending on co2 emission allowance price financial risks are further reinforced when the price of electricity is determined by natural gas fired plants marginal costs we aim to empirically assess the risks in eu coal plants margins up to the year 2020 parameter values are derived from actual market data monte carlo simulation allows compute the expected value and risk profile of coal plants earnings future allowance prices may spell significant risks on utilities balance sheets

dynamic incentives of environmental regulations the effects of alternative policy instruments on technology diffusion abstract we develop a framework for comparing empirically the effects of alternative environmental policy instruments on the diffusion of new technology market based and command and control approaches can he quantitatively compared by estimating the economic penalty that firms through their actions reveal to be associated with violation of standards in the context of concerns about global climate change we empirically examine the likely effects of pigouvian taxes technology adoption subsidies and technology standards we employ state level data on the diffusion of thermal insulation in new home construction comparing the effects of energy prices insulation cost and building codes

price drivers and structural breaks in european carbon prices 2005 2007 this article aims at characterizing the daily price fundamentals of european union allowances euas traded since 2005 as part of the emissions trading scheme ets the presence of two structural changes on april 2006 following the disclosure of 2005 verified emissions and on october 2006 following the european commission announcement of stricter phase ii allocation allows to isolate distinct fundamentals evolving overtime the results extend previous literature by showing that eua spot prices react not only to energy prices with forecast errors but also to unanticipated temperatures changes during colder events besides the sub period decomposition of the pilot phase gives a better grasp of institutional and market events that drive allowance price changes

information linkage dynamic spillovers in prices and volatility between the carbon and energy markets abstract the european union emissions trading system eu ets has strengthened the information flow and connection between carbon market and energy markets which makes the carbon energy system more complicated this paper investigates information linkages and dynamic spillover effects between the carbon and energy markets we adopt a systemic time series approach to study connectedness in both returns and volatility in the carbon energy system moreover a rolling windows method is used to show the dynamic features empirical results show that brent oil prices play an important role in affecting carbon price changes and risks feedback exists from the carbon market to other energy markets and electricity prices are shown to be the biggest information receiver in the system it is also shown that the level of connectedness in the volatility system is substantially higher than that in the returns system our results can provide useful implications for policymakers to design market mechanisms and market investors to manage their portfolios

multiple bubbles in the european union emission trading scheme abstract the european union emission trading scheme eu ets is the first large scale co 2 emission trading system in the world carbon allowances are financial assets potentially vulnerable to the behavior of traders and investors in fact the carbon price has been quite volatile since the inception of the market and it has recently hit very low values however to date no work exists to evaluate whether volatility and price spikes are due to episodes of speculation and price bubbles our paper fills this gap we use the recent approaches developed by phillips and yu 2010 phillips et al 2011 and phillips et al 2015a 2015b who propose a recursive right sided unit root approaches to detect and date stamp mildly explosive behaviors and carbon market exuberance we complement this methodology by using the wild bootstrap procedure by goncalves and kilian 2004 to control for the heteroschedasticity of carbon price data analyzing the eu ets front month contract price from 2005 to 2014 we find different episodes of price bubbles these episodes are not explained by similar behavior of the fundamentals but seem related to energy and environmental policy announcements our results can provide insightful policy implications in the context of the actual carbon market reform as well as the implementation of stricter financial regulations rules to co 2 trading

the impacts of liquidity dynamics on emissions allowances price different evidence from china s emissions trading pilots abstract the liquidities of china s emissions trading markets have significant impacts on emissions allowances price movement and pricing efficiency liquidity measures on illiquidity ratio and trade values indicate hubei emissions allowances hbea product has the highest liquidity shenzhen allowances sza and guangdong emissions allowances gdea products have the higher liquidity than beijing emissions allowances bea and shanghai emissions allowances shea products while tianjin emissions allowances tjea product has the lowest market liquidity in considered china s emissions trading pilots the dynamics of the illiquidity ratios for all selected emissions allowances products are negatively related with emissions allowances returns and trade volumes for bea tjea sza and hbea products are also negatively related with emissions allowances returns the dynamics of daily illiquidity ratios and trade based liquidity in beijing tianjin guangdong shenzhen hubei emissions pilots have significant volatility clustering impacts on the variances of regional emissions allowances returns previous market shocks of overnight and intraday price variations have the more persistent influences on the gdea returns than hbea returns reflecting greater inter day price ranges clustering effect

what happens to the relationship between eu allowances prices and stock market indices in europe abstract the stock market may reflect the economic conditions of an economy and a positive economic situation is expected to improve the companies profits which makes company shares more attractive since the expected dividends to shareholders will be larger theoretically higher economic activity leads to higher energy demand and consequently higher carbon emissions which give rise to higher eu allowances eua prices therefore the stock market and eua prices seem to be connected with causality going from the stock markets to eua prices this paper formally tests for it showing that the causality effectively runs from the stock market to the european climate exchange market furthermore the paper studies the effects of the evolution of european stock markets on the eua spot prices

competitiveness and legitimation the logic of companies going green in geographical clusters this study analyzes the logic behind the development of environmental responsiveness in companies that are located in geographical clusters drawing on previous research we contend that competitiveness and legitimation are important sources of variation in these companies environmental responses in particular the companies perceived rivalry competition tracking capabilities interaction with industry associations and network embeddedness influence their competitiveness and legitimation motivations for environmental responsiveness we used structural equation modeling to test these hypotheses on a sample of 251 clustered agricultural firms in spain the results support the hypotheses and provide a number of insights about the underlying motivations behind going green in geographical clusters

abatement and allocation in the pilot phase of the eu ets we use historical industrial emissions data to assess the level of abatement and over allocation that took place across european countries during the pilot phase 2005 2007 of the european union emission trading scheme using a dynamic panel data model we estimate the counter factual business as usual emissions scenario for eu member states comparing this baseline to allocated and verified emissions we find that both over allocation and abatement occurred along with under allocation and emissions inflation over the three trading years of the pilot phase we find over allocation of approximately 280 million euas and total abatement of 247 mt co2 however we calculate that emissions inflation of approximately 73 mt co2 also occurred possibly due to uncertainty about future policy design features

carbon pricing and system linking lessons from the new zealand emissions trading scheme abstract textbook theory of linking carbon systems suggests linking reduces marginal abatement costs contrasting theoretical work and policy analyses suggests that linking or at least unfettered linking may not always be beneficial the new zealand emissions trading scheme nz ets is unique in that until 2013 it allowed unlimited use of kyoto allowances nz ets thus provides an ideal context to explore the effect of linking and linking restrictions on carbon pricing of small systems using data on importation and exportation of allowances we provide the first empirical analysis of the determinants of allowance prices in the early phase of the nz ets our results indicate that imports of offsets rather than fundamentals have been the major price determinant moreover the pricing of new zealand units nzus can be placed into three distinct periods delineated by two structural breaks in the first period the system is largely autarkic in the second period as international offset prices drop below the nzu price the system becomes a price taker in the final period following policy interventions the system regains some independence the case of the nz ets shows that small trading systems need to impose or have the option to impose quantitative import restriction so as to reap the benefits lower abatement cost but not the drawbacks importation of distortions and market integrity issues of linking

how to explain carbon price using market micro behaviour abstractin this article we analyse the micro behaviours of the emitting companies and financial intermediaries in the european union emissions trading scheme eu ets and their influence on carbon prices based on the full sample community independent transaction log citl the micro behaviours can be observed in a closed system the micro behaviours of the emitting companies are divided into compliance trading and non compliance trading based on the emitting companies trading motivations the micro behaviours of the financial intermediaries are measured by their influence on the total supply and demand in the market then an ar garch model is established to examine the dynamic relationships between carbon prices and the micro behaviours of the emitting companies and financial intermediaries the estimation results suggest that the prices behaviours relationship is significant other important findings are as follows 1 the mean value of carbon prices positively depends on the compliance trading

investigating policy and r d effects on environmental innovation a meta analysis in the last decades a wide research effort has been devoted at the analysis of the determinants of environmental innovation ei whereas agreement seemed to emerge around a cluster of determinants mainly technology push market pull policy push pull and firm specific factors empirical analyses have failed to provide strong confirmation on the relevance of some core variables after a qualitative discussion of this literature we empirically assess it by exploiting meta regression analysis techniques to test the effectiveness of two determinants policy and r d our findings are clear as for the first we show that only certain types of policy have proven to affect ei in particular regulatory stringency as for r d we show that the use of estimation methods is not neutral to the outcome of the primary studies

causes of the eu ets price drop recession cdm renewable policies or a bit of everything new evidence the price of eu allowances euas in the eu emissions trading scheme eu ets fell from almost 30 tco2 in mid 2008 to less than 5 tco2 in mid 2013 the sharp and persistent price decline has sparked intense debates both in academia and among policy makers about the decisive allowance price drivers in this paper we examine whether and to what extent the eua price drop can be justified by three commonly identified explanatory factors the economic recession renewable policies and the use of international credits capitalizing on marginal abatement cost theory and a broadly extended data set we find that only variations in economic activity and the growth of wind and solar electricity production are robustly explaining eua price dynamics contrary to simulation based analyses our results point to moderate interaction effects between the overlapping eu ets and renewable policies the bottom line however is that 90 of the variations of eua price changes remains unexplained by the abatement related fundamentals together our findings do not support the widely held view that negative demand shocks are the main cause of the weak carbon price signal in view of the new evidence we evaluate the eu ets reform options which are currently discussed

carbon price drivers phase i versus phase ii equilibrium abstract the aim of this paper is to investigate the determinants of the carbon price during the two phases of the european union emission trading scheme eu ets more specifically relying on daily eu allowance futures contracts we test whether the carbon price drivers identified for phase i still hold for phase ii and evolve toward a long run relationship using cointegration techniques and accounting for the 2006 structural break in the carbon market we show that while a cointegrating relationship exists for both phases of the eu ets the nature of this equilibrium relationship is different across the two subperiods with an increasing role of fundamentals in phase ii deriving equilibrium values we show that the carbon price tends to be undervalued since the end of 2009

environmental efficiency and labour productivity trade off or joint dynamics a theoretical investigation and empirical evidence from italy using namea in this paper we test an adapted ekc hypothesis to verify the relationship between environmental efficiency namely emissions per unit of value added and labour productivity value added per employee we exploit namea data on italy for 29 sector branches and 6 categories of air emissions for the period 1991 2001 we employ data on capital stock and trade openness to test the robustness of our results on the basis of the theoretical and empirical analyses focusing on innovation firm performances and environmental externalities we would expect a positive correlation between environmental efficiency and labour productivity a negative correlation between the emissions intensity of value added and labour productivity which departs from the conventional mainstream view the hypothesis tested is a critical one within the longstanding debate on the potential trade off or complementarity between environmental preservation and economic performance which is strictly associated with the role of technological innovation we find that for most air emission categories there is a positive relationship between labour productivity and environmental efficiency labour productivity dynamics then seem to be complementary to a decreasing emissions intensity in the production process taking a disaggregate sector perspective we show that the macro aggregate evidence is driven by sector dynamics in a non homogenous way across pollutants services tend always to show a complementary relationship while industry seems to be associated with inverted u shape dynamics for greenhouse gases and nitrogen oxides this is in line with our expectations in any case ekc shapes appear to drive such productivity links towards complementarity the extent to which this evidence derives from endogenous market forces industrial and structural change and policy effects is discussed by taking an evolutionary perspective to innovation and by referring to impure public goods arguments

a multiscale analysis for carbon price drivers abstract this study proposes a multiscale analysis model to explore and identify the carbon price drivers at different timescales by introducing the latest multivariate empirical mode decomposition carbon price and its potential drivers are decomposed into several groups of simple modes with specific economic meanings the cointegration techniques error correction model and newey west estimator are combined to capture the carbon price drivers at similar timescales illustrated by the samples of the european union emissions trading system from 2009 to 2016 a few interesting results can be found that at the original data level among the three most important drivers of carbon price electricity price and stock index show positive impacts while coal price shows a negative impact at different timescales the effects of electricity and stock index appear comparatively earlier which drive carbon price from the short timescales and continue to strengthen however the impacts of coal oil and gas prices are lagging behind which respectively drive the carbon price at the medium and long timescales

review of taiwan s climate policy after copenhagen abstract the copenhagen accord in 2009 initiated new opportunities for international cooperation in reducing greenhouse gas ghg emissions the purpose of this study was to review taiwan s current climate policy and in response to the copenhagen accord to deliberate this policy in the light of new strategic thinking the study proposes a two stage approach with a dividing line in 2020 in the first stage from now until 2020 strategy should be based on cost constraints with a suggested reduction cost below 60 t co 2 and implementation of domestic ghg emissions trading scheme and reduction strategies in the second stage from 2020 and beyond action by taiwan should accord with international cooperative actions to link its domestic emissions trading scheme with the international carbon market

the changing face of financial development abstract we provide evidence from a large number of countries which demonstrates the changing nature of the finance growth nexus specifically we show that financial depth is no longer a significant determinant of long run growth instead we find evidence to suggest that certain financial reforms have sizeable growth effects which can be positive or negative depending on how well banks are regulated and supervised

economic instruments and induced innovation the european policies on end of life vehicles abstract the paper addresses the mechanisms by which specific economic instruments based on the producer responsibility principle prp can influence innovation when environmental policy has impact on very complex industrial subsystems we consider the eu policy on end of life vehicles directive 2000 53 ec on elvs as a representative case study of multiple industry prp instrument dynamic efficiency problems in order to achieve ambitious policy targets on elv recovery recycling reuse interrelated sequences of single innovations in both upstream car making and downstream car recycling recovery should take place we explore the extent to which the introduction of a free take back ftb instrument can influence industrial actors in contributing to innovation paths that are still marked by technological uncertainty evolving capabilities and different cost benefit balances for actors themselves we conclude that differently from static approaches in which the ei and its formulation is neutral with respect to policy effectiveness the dynamic efficiency of eis in elv like problems depends both on where along the production to waste chain and how in terms of net cost allocation the specific incentive is introduced consequently in order to generate a policy desired innovation path the way in which the ei related incentive allocated to a certain industry is transmitted to other industries whether upward or downward along the chain is also relevant disregarding these effects can imply a dissipation of innovation incentives and the generation of regulation induced rents for some actors cannot be ruled out policies based on prp should consider eis in conjunction with enforceable voluntary agreements

the market microstructure of the european climate exchange abstract this paper analyzes the market microstructure of the european climate exchange the largest eu ets trading venue the ecx captures 2 3 of the screen traded market in eua and more than 90 in cer volume growth has averaged 277 in eua between 2005 and 2009 and 724 in cer since 2007 spreads range from 0 0188 to 0 0406 for eua and 0 0276 to 0 0796 for cer the median proportion of the spread due to adverse selection reaches 76 for eua and 75 for cer realized volatility bid ask spreads and adverse selection costs decline with verified emission releases market impact estimates imply that an average trade will move the eua market by 1 06 euro centimes and the cer market 1 45 the ecx is providing between 75 and 88 of price discovery for eua trading and between 64 and 72 for cer we find imbalances in the order book help predict returns for up to three days a simple trading strategy that enters the market long or short when the order imbalance is strong is profitable even after accounting for spreads and market impact

extended producer responsibility instruments and innovation in eco design an exploration through a simulation model abstract this paper presents an agent based simulation model that models both economical and physical relations between firms recyclers and consumers this framework allows an investigation into the connection between physical environmental variables waste flows virgin material flows and economic decisions of agents in the product chain i e firms innovation strategies consumers choices and development of recycling activities the paper highlights the value of using agent based modeling as an operational tool to investigate the effect of waste prevention policy on economic and technological decisions of agents we focus on three types of extended producer responsibility epr instruments which are recycling fees tax subsidy and norms the simulation results show that the impact of each instrument depends on the policy design in particular on the level of stringency and on the reward system which is implemented we show that only tax subsidy systems and stringent norms can lead to radical innovations and to significant changes in product designs in the case of tax subsidy the impact relies more on an innovation effect while in the case of norm it mainly relies on a selection effect

eua and scer phase ii price drivers unveiling the reasons for the existence of the eua scer spread abstract this article studies the price relationships between eu emissions allowances euas valid under the eu emissions trading scheme eu ets and secondary certified emissions reductions scers established from primary cers generated through the kyoto protocol s clean development mechanism cdm given the price differences between euas and scers financial and industrial operators may benefit from arbitrage strategies by buying scers and selling euas i e selling the eua scer spread to cover their compliance position as industrial operators are allowed to use scers towards compliance with their emissions cap within the european system up to 13 4 our central results show that the spread is mainly driven by eua prices and market microstructure variables and less importantly as we would expect by emissions related fundamental drivers this might be justified by the fact that the eu ets remains the greatest source of cer demand to date

modeling persistence of carbon emission allowance prices this study reexamines the issue of persistence in carbon emission allowance spot prices using daily data and covering the period from 28 2 2007 to 14 05 2014 for this purpose we use techniques based on the concept of long memory accounting for structural breaks and non linearities in the data with both of these aspects potentially affecting the degree of persistence our results indicate that while there is no evidence of non linearity when allowing for structural breaks persistence of shocks to the carbon emission allowance is markedly reduced with the same being transitory in nature for recent sub samples

time and frequency connectedness among oil shocks electricity and clean energy markets abstract this paper examines the time and frequency connectedness among electricity carbon and clean energy markets and oil price demand and supply shocks in doing so we use the spillover method proposed by diebold and yilmaz 2012 and its extension in the frequency domain by barunik and k ehlik 2018 we find increased connectedness during the global financial crisis as well as in the shale oil revolution period the total connectedness is also higher in the short run compared to the long run due to their low connectedness electricity futures can act as a risk diversifier and safe haven asset against oil shocks net pairwise directional connectedness among oil shocks and the clean energy index is higher during the shale oil revolution these results have important implications for investors with different investment time horizons

do transaction costs influence firm trading behaviour in the european emissions trading system this study is one of the first to empirically investigate firm trading behaviour and the importance of permit trading transaction costs such as information costs and search costs in the first phase of the european union s emissions trading system eu ets the signs and significance of our constructed transaction costs proxy variables indicate for a presence of these costs in the initial years of the eu ets in particular this paper shows that ets firms with the smaller number of installations and with less trading experience were less likely to participate in the european emissions trading market and traded the lower quantities of permits furthermore these firms chose to trade permits indirectly via third parties this study also supports the concerns that transaction costs could be excessive for smaller participants and firms operating in the new eu member states

a big data study on emitting companies performance in the first two phases of the european union emission trading scheme as co2 emissions are quantified by allowances and traded in markets wise trading strategies will bring emitting companies higher profits or lower costs based on the big data of community independent transaction log citl this article hereby presents a micro study on the emitting companies efforts in increasing profits and saving costs during the allowances trading in the first two phases of the european union emission trading scheme eu ets the efforts are measured by an after action factor of trading performance which is built on a series of behaviour and monetary variables by comparison demanders of the emitting companies are more inclined to reach a higher trading performance while that inclination is heterogeneous among the suppliers in addition emitting companies with lower emission levels had a better trading performance with a higher proportion of low emitting companies the manufacturing sector had a better trading performance than the energy sector the effect of the trading requirement on trading performance are investigated via a quantile regression mode results suggest that 1 the selling requirement of suppliers has a positive effect on their trading performance while the effect becomes weaker when the selling requirement increases 2 the buying requirement has a positive effect on the demanders trading performance only when the requirement is high and the effect becomes stronger as the requirement increases and 3 when the buying requirement is at a lower level demanders trading performance becomes worse as the requirement grows the conclusion is that the emission level industrial sector and trading requirement do have influences on the trading performance of emitting companies in emission trading

dynamic incentives by environmental policy instruments a survey abstract in this paper i survey and discuss recent developments on the incentives provided by environmental policy instruments for both adoption and development of advanced abatement technology a main conclusion to be drawn from the literature is that under competitive conditions market based instruments usually perform better than command and control moreover taxes may provide stronger long term incentives than tradable permits if the regulator is myopic if the government can anticipate new technology or is able to react on it optimally regulatory policies by virtue of administered prices taxes and policies by setting quantities issuing tradable permits are almost equivalent the literature also shows that under competitive conditions there is no difference between auctioning permits and grandfathering moreover timing and commitment of environmental policy is not crucial for adoption under competitive conditions commitment has positive incentive effects however if an r d sector has market power in the presence of market imperfections the ranking of the different policy instruments is ambiguous

the vermont common assets trust an institution for sustainable just and efficient resource allocation both private and public sectors have failed to adequately provide critical ecosystem goods and services or an equitable distribution of wealth and income to address this problem the vermont legislature is considering the creation of a vermont common assets trust vcat that would make the state s atmosphere aquifers and other resources created by nature or by society as a whole the common property of all vermonters present and future under the trust a board of trustees would have the legal obligation to manage these assets for the benefit of all vermonters including future generations this paper first explains why certain resources are likely to be managed more sustainably fairly and efficiently as common property than as private property it then discusses mechanisms for integrating assets into the trust estimates of potential revenue from a vcat suggest that it could eliminate the state budget deficit contribute to a better distribution of wealth and resources and help address critical ecological problems survey results suggest that a vcat is politically feasible the vcat promises to be an important pilot project that could later be scaled up to a national or global level

can downstream waste disposal policies encourage upstream design for environment design for environment takes place when firms explicitly incorporate environmental issues in their product design and manufacturing decisions joseph fiksel 1996 to reduce waste associated with consumer products for example firms can reduce product weight including the amount of packaging that comes with a product and make products easier and less costly to recycle the latter can be accomplished by changing the type of material used in a product avoiding mixing of materials in a single product coding and labeling when different materials are used and designing for ease of disassembly u s congress office of technology assessment 1992 fiksel 1996 an important debate centers around the question of whether design for environment dfe needs to be explicitly targeted using policy instruments focused upstream on producers or whether downstream instruments send sufficient signals back upstream one important downstream instrument is a disposal fee i e charging households a price per pound per bag or per can for their trash many observers feel that downstream instruments do not send appropriate signals back upstream some economists and others have suggested on the other hand that disposal fees can in theory send signals upstream to producers karen palmer and walls 1998 we find that disposal fees provide incentives for efficient dfe only when there is a fully functioning recycling market i e only when recyclers pay households a price for each of their recyclable items and that price varies with the degree of product recyclability in the real world transactions costs of paying households for each individual item recycled would be prohibitively high in a more realistic setting in which households may place some items in a recycling bin but are not paid for doing so a disposal fee by itself will not yield a social optimum it encourages households to place items in the bin but all items allowed in the bin are of equal value to the household i e there is no reason to prefer an easily recyclable aluminum can to a difficult to recycle plastic milk jug this means that there is no signal to producers to make products more recyclable if the government can set product taxes that vary with product recyclability the social optimum can be restored but this option is not practicable 2 we argue that the infeasibility of i paying households for recycling and ii taxing products according to their recyclability means that a first best outcome is no longer attainable instead we set up a constrained second best optimum and solve for policy instruments that achieve this outcome we find that a disposal school of economics and finance victoria university of wellington wellington new zealand walls is also a university fellow with resources for the future washington dc the helpful comments of karen palmer don fullerton and hilary sigman are greatlv appreciated 1 manufacturer take back requirements such as germany s well known packaging take back law were developed at least in part as a way to encourage dfe see www oecd org env epr index htm for updates from a series of oecd workshops held in 1997 1999 on the broader topic of extended producer responsibility in practice individual german producers do not actually take back their own products at end of life they have formed a consortium that arranges to collect members waste from households marked with a green dot and recycle it we do not address take back mandates in this paper 2 in calcott and walls 1999 we derive these taxes don fullerton and wenbo wu 1998 show that a direct subsidy to recyclability combined with other instruments can yield a social optimum this subsidy depends on production function parameters thus if firms differ the subsidy would vary across firms more i mportantly observing and measuring recyclability to determine subsidy payments would be virtually impossible

determinants of environmental innovation in us manufacturing industries abstract this paper provides new evidence on the determinants of environmental innovation we employ panel data models to study how environmental innovation by us manufacturing industries responded to changes in pollution abatement expenditures and regulatory enforcement during the period 1983 through 1992 we find that 1 environmental innovation as measured by the number of successful environmental patent applications granted to the industry responded to increases in pollution abatement expenditures however 2 increased monitoring and enforcement activities related to existing regulations did not provide any additional incentive to innovate we also find some empirical evidence that environmental innovation is more likely to occur in industries that are internationally competitive

global mechanisms for sustaining and enhancing pes schemes article i nfo an international payment for ecosystem service ipes schemes may be one of the only mechanisms available to stimulate the provision of vital non marketed ecosystem services at the global level as those nations that benefit from global ecosystem services ges cannot readily force other sovereign nations to provide them currently international trade offers trillions of dollars in incentives for countries to convert natural capital into marketable goods and services and few payments to entice countries to conserve natural capital in order to sustain critical non marketed ecosystem services we examine the biophysical characteristics of climate change and biodiversity to understand the obstacles to developing effective ipes schemes we find that none of the existing schemes for providing ges are adequate given the scale of the problem a cap and auction scheme for co2 emissions among wealthy nations could fund ipes and simultaneously deter carbon emissions to disburse funds we should adapt brazil s icms ecologico and apportion available funds to targeted countries in proportion to how well they meet specific criteria designed to measure the provision of ges individual countries can then develop their own policies for increasing provision of these services ensured of compensation if they do so indirect ipes should include funding for freely available technologies that protect or provide ges such as the low carbon energy alternatives that will be essential for curbing climate change markets rely on the price mechanism to generate profits which rations technology to those who can afford it reducing adoption rates innovation and total value

the impact of the european union emission trading scheme on electricity generation sectors in order to comply with their commitments under the kyoto protocol france and germany participate to the european union emission trading scheme eu ets which concerns predominantly electricity generation sectors in this paper we seek to know if the eu ets gives appropriate economic incentives for an e cient and strong system in line with kyoto commitments because if so electricity producers in these countries should include the price of carbon in their costs functions after identifying the di erent sub periods of the eu ets during its pilot phase 2005 2007 we model the prices of various electricity contracts and look at their volatilities around their fundamentals while evaluating the correlation between the electricity prices in the two countries we finnd that electricity producers in both countries were constrained to include the carbon price in their cost functions during the rst two years of operation of the eu ets during this period german electricity producers were more constrained than their french counterparts and the inclusion of the carbon price in the cost function of electricity generation has been so much more stable in germany than in france furthermore the european market for emission allowances has increased the market power of the historical french electricity producer and has greatly contributed to the partial alignment of the wholesale price of electricity in france with those of germany

an overview of co2 cost pass through to electricity prices in europe this paper investigates the link between wholesale electricity prices in europe and the co2 cost i e the price of european union allowances euas over the two first phases of the european union emissions trading scheme eu ets we set up a theoretical framework and an empirical model to estimate to what extent daily fluctuations of co2 costs may have impacted electricity prices regarding estimation results for the first phase of the eu ets about 42 of estimated pass through rates appear to be statistically significant while only one third of them are statistically different from zero in the second phase we try to improve those results by proposing alternative estimates based on the eu ets compliance periods
