The Low Carbon Fuel Standard (LCFS) plays a critical role in California’s efforts to reduce greenhouse gas (GHG) and air pollutant emissions from transportation. The LCFS incentivizes the use of fuels with lower life cycle GHG emissions by using a credit market mechanism to provide incentives for low-carbon fuels, using revenue generated by charges applied to high-carbon ones. Maintaining an approximate balance between LCFS credit and deficit supplies helps support a stable LCFS credit price and the broader transition to low-carbon transportation. The Fuel Portfolio Scenario Model, presented here, evaluates bottom-up fuel supply and LCFS compliance to inform LCFS policy decisions. We considered two key fuel demand scenarios: (1) the Low Carbon Transportation scenario, reflecting the expected transition to low-carbon transportation in California over the next 15 years, and (2) the Driving to Zero scenario, featuring a significantly higher consumption of petroleum gasoline. In both scenarios, 2030 LCFS targets around 30% resulted in a near-balance between credits and deficits, with some banked credits remaining. Several additional scenarios were modeled to explore the impact of target trajectory timing, alternate post-2030 targets, greater biofuel use, and other parameters. This fuel portfolio scenario modeling work can meaningfully inform policy development.

The study examines the relationship and linkages between spot and future prices of European Union Emission Trading Systems (EU-ETS) during 2019–2021. Dynamic conditional correlation specification of multivariate generalized autoregressive conditional heteroskedasticity (MGARCH) model was employed to examine the time-varying correlation between spot and future prices. Also, vector autoregression mean model and MGARCH-Baba-Engle-Kroner-Kraft volatility model was jointly estimated to model the spillover between EU ETS spot and future prices in the first and second moments. Lastly, we utilize the variance-covariance matrix of joint mean-variance model estimation to derive the optimal conditional hedge ratio as well as the hedge effectiveness of EU ETS future contracts. Our findings reveal a high conditional correlation and significant spillover between carbon spot and future markets in EU. Further, our study uncovers a high degree of hedge effectiveness for EU ETS future contracts. This is possibly the first study that examines the linkages between EU ETS spot and future prices pertaining to the recent transition stage of phase III and the initial stage of ongoing phase IV of the ETS market. Our findings pinpoint to ETS markets becoming more complete and in turn offering optimal hedging avenues. JEL Codes: G15, C58, Q38 [ABSTRACT FROM AUTHOR]

Carbon pricing is a key component of current climate policy agendas. There are a variety of societal and health impacts from carbon pricing interventions (e.g. from improved air quality). A better understanding of potential health impacts and how they depend on context and policy design is crucial to improve the political feasibility and fairness of carbon pricing. Recent reviews have synthesized evidence on the effectiveness, equity and perceptions of carbon pricing and on the health co-benefits of mitigation. This review provides a narrative structured synthesis of the health impacts of carbon pricing. We identified 58 relevant publications of which all were modelling studies. We classify review findings into policy-relevant categories, synthesizing information on how carbon pricing affects health outcomes when implemented in different contexts, in isolation or as part of policy mixes. Findings suggest that internalization of health co-benefits in optimal price level estimates could lead to substantial mitigation in some regions. There are also opportunities to design carbon pricing to improve health outcomes, including through progressive or targeted use of revenues to improve food security, subsidize healthier diets or promote active transportation. Revenue use, price differentiation, market size and permit allocation of emissions trading schemes (ETS), and interaction with other public health or mitigation policies all influence health outcomes. Overall, the health impacts of carbon pricing are highly context-specific and further evidence is needed, particularly on health inequalities and ex-post analysis. However, existing evidence suggests that it is possible to design health-beneficial carbon pricing policies, thus enhancing policy acceptability and feasibility. Key policy insights: Internalizing health co-benefits into optimal carbon pricing estimates could lead to substantial emission reductions in some regions, although additional action is needed to encourage price levels compatible with climate targets Health co-benefits can be boosted through key elements of policy design including price differentiation across commodities and regions, revenue use or ETS design Careful policy design can enhance health gains at a small or insignificant cost in terms of climate mitigation effectiveness and efficiency. The implementation of carbon pricing as part of broader policy mixes with a strong focus on progressivity and equity is crucial to achieving health co-benefits [ABSTRACT FROM AUTHOR]

Carbon prices have grown remarkably in the European Union (EU) Emissions Trading System (ETS) in recent years, raising distributional concerns. Revenues are expected to grow with higher carbon prices, thus providing resources to address distributional issues. Beyond a certain point, however, higher prices can discourage the purchase of allowances and ultimately reduce revenues, describing a Carbon Laffer Curve (CLC). We empirically investigate the CLC in the EU ETS between 2012 and 2021 using auction revenues at the country level. Results indicate that ETS revenues follow an inverted‐U relationship in both the volume and the price of auctioned allowances, with an estimated optimal price between 86 and 125 euros.

Civil aviation significantly contributes to "hard-to-abate" emissions, responsible for 2% of global CO2 emissions. This paper examines the most effective policies to promote Sustainable Aviation Fuels (SAFs) in Italy, using a multi-level policy analysis and a stakeholder-based case study approach. The policies reviewed comprise the international, European, and national level. The paper analyses at the international level, ICAO CORSIA and, at the European level, the Renewable Energy Directive (RED), ReFuel EU, and the EU Emissions Trading System (EU ETS) for aviation. Italy has not yet implemented specific policies targeting SAF transition, which is challenging due to commercialization issues and policy inconsistencies. These include the price gap between SAF and conventional fuels, different definitions adopted, and environmental objectives pursued with respect to sustainable fuels by ICAO and the EU. Other challenges include double-counting risks and fuel tankering practices. This article contributes to Italy's SAF policymaking by developing a stakeholder-based quantitative survey, whose results suggest that three measures are key: tax subsidies for technology and infrastructure users, tax credits for upgrading production infrastructure, and tax breaks for SAF-using companies, fuel handlers, and distributors.

Mitigating greenhouse gas emissions and reducing air pollution represent two pressing and interwoven environmental challenges. While international carbon markets, such as the European Union emissions trading system (EU ETS), have demonstrated their effectiveness in curbing carbon emissions (CO2), their indirect impact on hazardous copollutants remains understudied. This study investigates how key toxic air pollutants--sulfur dioxide (SO2), fine particulate matter (PM2.5), and nitrogen oxides (NOx)-- evolved after the introduction of the EU ETS with a comparative analysis of regulated and unregulated sectors. Leveraging the generalized synthetic control method, we offer an ex post analysis of how the EU ETS and concurrent emission standards may have jointly generated sizable pollution reductions in regulated sectors between 2005 and 2021. We provide an aggregate assessment that these pollution reductions could translate into large health co-benefits, potentially in the hundreds of billions of Euros, even when bounding the effect of emission standards. These order-of-magnitude estimates underscore key implications for policy appraisal and motivate further microlevel research around the health co-benefits of carbon abatement. [ABSTRACT FROM AUTHOR]

This article offers insights into how leadership can be provided to advance the EU policy-making process through a case study of the policy-making for the new EU emissions trading system for buildings, road transport and additional sectors (ETS-2). Conceptually, it contributes to the literature on leadership in the EU by developing a three-part framework for observing leadership in EU policy-making, focussing on the intentions of an actor, the effects of the actions of an actor and the perceptions of other actors. The article also contributes to the literature on interactions between leaders in EU policy-making. Empirically, we provide a process tracing analysis of leadership in the policy-making process for the ETS-2. Using our framework, we examine five key leadership moments, showing how Denmark provided cognitive leadership, Germany provided exemplary and structural leadership, and the Commission and rotating Presidencies provided cognitive and entrepreneurial leadership. Our empirical analysis shows that various types of leadership were partially simultaneously and partially consecutively provided, with some leaders following up on the leadership strategies of others. We term this dynamic ‘sequential leadership’. Our finding confirms the importance of seeing leadership as a relationship, not just between leaders and followers, but also amongst leaders.

The emissions trading system (ETS) is one of the effective measures for energy conservation and emissions reduction, and the impact of the carbon ETS can be reflected in the willingness of enterprises to pay for carbon emissions reductions. However, there has been little research exploring the relationship between the two. Therefore, this study fills this knowledge gap by comprehensively investigating the influence of China carbon ETS policy (ETSP) on the willingness of enterprises to pay for carbon emissions reductions, and incorporates environmental awareness (EA), green technology innovation (GTI), and climate risk awareness (CRA) into the research model, thus constructing a new theoretical framework. Empirical analysis is conducted using the structural equation modeling method based on survey data from 478 Chinese enterprises. The results indicate that: (1) the China carbon ETSP can promote the willingness of enterprises to pay for carbon emissions reductions. (2) The China carbon ETSP can also promote the EA, GTI, and CRA of enterprises. (3) EA, GTI, and CRA can also promote the willingness of enterprises to pay for carbon emissions reductions. (4) Mediation effect analysis revealed that EA and CRA, respectively, play a mediating role in the influence process of the China carbon ETSP on the willingness of enterprises to pay for carbon emissions reductions. However, GTI does not have a mediating effect in this process. (5) Comparative mediation analysis found no significant differences in the mediating effects of EA and CRA. This study provides constructive practical recommendations for future carbon market mechanism construction and enterprise emission reduction policy formulation. It also offers guidance and reference for the behavioral decision‐making of enterprises in carbon market transactions, and carries practical significance and policy advocacy value.

Under the constraints of the ‘dual carbon’ goals, investigating the impact of market-based environmental regulations on enterprise value has significant implications for enhancing the enthusiasm and initiative among enterprises to participate and achieving a ‘win-win’ situation in environmental protection and enterprise development. Using the carbon emissions trading pilot policy as a natural experiment and data from eight pilot industries in China's A-share market from 2008 to 2020, this study further investigated the impact mechanisms and heterogeneity of the policy on enterprise value on the basis of the parallel trend sensitivity test and the processing effect heterogeneity test, and examined the effects of the policy on enterprise value using robust estimators. The results showed that: ① After the implementation of the carbon emissions trading pilot policy, the enterprise value in the pilot area significantly increased, and this conclusion held after a series of robustness tests. ② Mechanism analysis found that this policy could improve enterprise value by improving enterprise ESG performance and that analyst attention had a dynamic moderating effect. By adjusting the two paths of the intermediation process, analysts not only adjusted the impact of the carbon emissions trading pilot policy on enterprise ESG performance but also adjusted the impact of enterprise ESG performance on enterprise value, thus strengthening the mediating role of enterprise ESG performance. ③ Heterogeneity analysis showed that the effects of this policy were more pronounced in regions with strong law enforcement, high attention to environmental governance, and an 'open economic order' business environment. Based on these research results, countermeasures and suggestions are put forward, including: focusing on the key links of the implementation of the carbon emissions trading pilot policy; actively improving the allocation mechanism for carbon market quotas and giving full play to their incentive mechanisms; standardizing the behavior of ESG information disclosure, and continuously improving the ‘information transmission’ and ‘external supervision’ functions of analysts to further strengthen the catalytic role of ESG performance. Additionally, the construction of a ‘promising government’ should be strengthened, the important role of local governments to environmental governance should be heeded, law enforcement should be strengthened, a neutral and inclusive competition policy should be maintained, and the high-quality development of the carbon trading market with a competitive open market should be promoted.

Amongst the most devastating extreme weather events in recent years, the 2022 Pakistan floods ostensibly triggered a new-found urgency to reduce emissions and redress other underlying causes of human-induced global warming. Yet multinational corporations and Western governments remain non-committal about shifting away from non-renewable energy, offering meaningful climate and debt financing, or substantively reducing emissions. Meanwhile, the modalities of capital accumulation in postcolonial contexts such as Pakistan are destroying already vulnerable ecosystems, even as they reinforce logics of expropriation and uneven development inherited from colonial times. As Pakistan experiences a demographic explosion and mainstream politics becomes increasingly reactionary, the imperative of posing an alternative hegemonic conception to the dominant development paradigm is ever more acute. This Commentary interrogates the meaning of climate justice so as to bring the global political economy into conversation with the demographic, environmental, and economic trends in the post-colony, with a specific focus on the 2022 floods in Pakistan. It is contended that the Pakistan case can be broadly extrapolated to postcolonial South Asia and sub-Saharan Africa, regions that are home to the fastest growing young populations in the world, and also amongst the most vulnerable to climate change.

The valuation of ecosystem services in high Andean zones, specifically in páramo ecosystems, is essential as they provide livelihoods for local livelihoods through water regulation, water storage, carbon sequestration, protection against landslides and floods, tourism and biodiversity, which is why establishing ecosystem services is essential. The present research focuses on a comprehensive review of peer-reviewed studies related to ecosystem services in South America and Ecuador using Science Direct, Taylos & Francis and Springer databases (search for titles, abstracts and keywords: The search terms used were the combination of the following keywords: "ecosystem services", "payment ecosystem services", "paramo", "Andes", "Ecuador", "grassland". From the bibliographic search, articles were considered only if they met the following criteria: English language articles, focused on high Andean ecosystems, search periods 2010-2020. It has been shown that there are several gaps in ecosystem services issues such as PES (payments for environmental services) as they influence the management of natural resources, also CE (Emissions Trading) are useful to make participants reflect on specific elements of payments for environmental services. The most important findings in this context were the poor distribution of wealth and lack of knowledge of the processes to access these environmental benefits. [ABSTRACT FROM AUTHOR]

The carbon emissions trading system (CETS) is a crucial market-based tool aimed at achieving the goals of “carbon peaking” and “carbon neutrality”, and plays a pivotal role in promoting the green development of the logistics industry. The green total factor productivity (GTFP) of the logistics industry is a key indicator used to measure the green development level of the logistics industry. The research on the CETS and the GTFP in the logistics industry(LGTFP) is currently lacking. Accurately assessing the impact of CETS on LGFP is crucial for improving the construction of the CETS and promoting the green transformation of the logistics industry. Utilizing a combined approach of system dynamics and econometrics, this study examines the effects of CETS on the LGFTP. In this study, the impact mechanism of CETS on the LGTFP is analyzed by constructing a causal relationship diagram using system dynamics theory. And then, we construct a multi-period differencein- difference (DID) model using panel data from 30 Chinese provinces spanning from 2010 to 2020 to verify the impact of CETS on LGTFP. The findings reveal that: (1) CETS significantly promotes LGTFP, and this conclusion is consistent even after conducting robustness tests. (2) Green technological innovation is identified as the primary influencing mechanism of CETS in enhancing LGTFP, while industrial upgrading does not play a positive mediating role, contrary to established studies. (3) Heterogeneity analysis reveals that CETS has a significant promotion effect on LGTFP in central and western regions, and resource-based provinces, but not yet in eastern regions and non-resource-based provinces. Based on the empirical analysis, we propose relevant policy recommendations to improve China’s CETS and promote the improvement of LGTFP. [ABSTRACT FROM AUTHOR]

With the gradual shift from dual control of energy consumption to dual control of carbon emissions, energy quota trading (EQT) and carbon emissions trading (CET) policies will be implemented in parallel in China. EQT policy will significantly affect the market performance and policy effects of CET, which consequently affects the dual control of carbon emissions. Therefore, constructing a system dynamics model coupling the national CET, EQT, and electricity markets, this paper researches the impact of EQT policy and its parameter design on the market performance and policy effects of CET through scenario analysis. The results show that: (1) Implementing EQT policy will reduce CET price and trading volume, negatively affecting CET market performance. This indicates that there is a certain substitution between EQT and CET. (2) EQT policy can enhance the emission reduction and decarbonization effects of CET policy. By curbing thermal power investment and generation and promoting green power, the EQT policy reduces carbon emissions by about 4.87% and optimizes the power supply structure. (3) To scientifically design the EQT policy parameters, lower energy saving targets and energy quota benchmark prices can alleviate the negative impact on CET market performance, but are not conducive to improving CET policy effects.

The transport sector is responsible for around 20% of global CO2 emissions, and road transport alone contributes to three-quarters of that share. A separate Emissions Trading System (ETS) in the EU will be implemented in 2027, covering road transport, buildings and additional sectors (mainly small industry). The likely outcomes of such policy are higher fuel prices, leading to less fuel consumption and reduced road transport emissions. Given that the inclusion of road transport in the EU ETS was originally proposed by the UK in the 2000s, and that the UK is exploring possible improvements to its own UK ETS, it is not impossible that the idea of emissions trading in road transport could be revisited in the UK. This article explores differences in perceptions of fuel price increases as a result of an increase in fuel duties or as a result of the introduction of a parallel ETS for road transport. This research employs a Serious Game to elicit perceptions. The game was designed to create situations where car drivers would need to make decisions in response to an increase in the pump price of fuel. Ultimately, the idea was to get the study participants to reflect on their travel decisions both in the game and in real life. Possible responses included changing their cars, modifying their travel behaviour and moving house. The data was analyzed using an interpretive approach, which contributed to the understanding of how participants experience and rationalize their decisions after fuel price increases. The main finding is that emissions trading seems to be seen more positively than an increase in fuel duties. The study participants associated emissions trading with a reduction in GHG emissions, and fuel duty increases to an increase in pump prices. When they were reminded that emissions trading would also cause pump prices to increase, they still seemed to be open to the idea of such a policy, and when they were reminded that the increase in fuel duties would also be aimed at reducing GHG emissions, they changed their attitude slightly towards a more positive one.

Climate policies are often evaluated using criteria that are heterogeneous and misaligned with the stated aims of these policies. By combining legal research methods with insights from economic theory, we systematically map and analyze the legal objectives of the European Union (EU) Emissions Trading System (ETS), a key climate policy instrument. We find that the EU ETS is shaped by a nuanced internal normative framework, the principal goal of which is emissions reduction, combined with three secondary goals of cost-effectiveness, economic efficiency and equity, and a meta-goal of coherence. Based on the contents and interrelations of these legal objectives, we formulate evaluation criteria that can be used to critically analyze and evaluate the EU ETS performance in a more comprehensive, transparent, and comparable manner. The resulting methodology is applicable to other environmental policies and jurisdictions. [ABSTRACT FROM AUTHOR]

The legal tools to avoid the potential disasters of climate change are already available, at least according to economists. Economists overwhelmingly prefer carbon pricing tools like carbon taxes and cap-and-trade programs to combat climate change and guide the energy transition. Carbon pricing is more cost effective at lowering carbon and other greenhouse gases (GHGs) than other legal options such as efficiency standards, renewable portfolio standards, subsidies, and tax credits and deductions. Unlike those other options, carbon pricing targets both the supply of and the demand for GHG-emittingproducts and services; moreover, it gives firms and consumers flexibility in how best to respond to the tax or the cap, whether by conserving more or switching to alternatives. For the most part, however, U.S. lawmakers have eschewed carbon pricing in favor of the less-effective and more-costly non-pricing alternatives. The preference is due in large part to concerns over the distributive implications of carbon pricing, namely that it would result in an unjust energy transition. Many scholars, policymakers, and environmental justice advocates worry that since carbon pricing by design raises energy prices, it will disproportionately burden the poor, who spend a greater share of their budget on energy. They also worry that carbon pricing will disproportionately benefit the rich, such as through capital tax su)aps or grandfathered emissions permits. Numerous recent economic studies have addressed the distributional implications ofpricing and non-pricing climate policy instruments, yet those studies haue received limited attention from legal scholars . Nor hat)e economists compared and contrasted the distribution of pricing with non-pricing policies. This Article therefore surveys those economic analyses to show that ajust transition is possible with carbon pricing. First, the United States currently relies on nonpricing policies that are themselves unjust: performance standards add costs that impose a disproportionate burden on the poor while subsidies and tax expenditures primarily benefit the rich. Carbon pricing can displace many of these laws and thereby eliminate their unjust impact. Second, the cost burden and regressivie of carbon pricing are overstated, so the impact on the poor will likely be much lower than commonly assumedand might even be progressive for the poorest households because of the indexing of government transfers. Third, the ways in which revenues raised from carbon pricing are recycled play an important role: lowering other distortionary taxes like those on capital while allocating some money for government transfer programs and lump-sum rebates to the poorest households can balance efficiency and equity. This Article therefore argues that concerns over a just transition should not be a barrier to implementing carbon pricing, which is the most efficient and effective means for lowering GHGs and thus avoiding the harms of climate change.

Considering carbon emission in inventory management model is a hot topic in current academic circles. Studying inventory pricing can provide managers with better managerial insights. Economic order quantity model mainly solves the inventory management problem of demand determination. However, due to the complex market environment in real life, it is difficult to meet the conditions of constant demand. In addition, with the enhancement of low-carbon awareness of enterprises, the study of pricing model based on low-carbon policies has also attracted the attention of a large number of scholars. The robust optimization theory is applied, the inventory pricing model of demand fluctuation under carbon cap, carbon tax and carbon cap-and-trade policies is considered, the robust equivalence form of the problem is studied. The profit comparison under different policies is given. Numerical experiments show that the carbon cap-and-trade policy can better control the carbon emission of enterprises. [ABSTRACT FROM AUTHOR]

Facing the dual pressures of the exacerbation of global climate change and the deterioration of the domestic environment caused by pollution, China has clearly adopted environmental regulatory measures to improve the climate environment. One measure is the carbon emissions trading scheme (CETS), which serves as a notable example of the country's efforts to improve the climate environment. We gathered panel data from 285 prefecture‐level cities in China from 2005 to 2018 and used the Difference‐in‐Differences (DID) model to empirically examine the synergistic effects of the CETS on carbon emissions and air pollution. The results indicate that CETS have been effective in reducing urban carbon emissions by approximately 9.8%. Additionally, the schemes have caused a simultaneous reduction in particulate matter (PM)2.5 emissions by 11.7% and sulfur dioxide (SO2) emissions by approximately 9.7%, mitigating urban air pollution in China. It demonstrates that the scheme has significant synergistic effects on carbon emissions and air pollution. To achieve synergistic effects of CETS, effective measures include reducing energy intensity and upgrading the industrial structure. The implementation of CETS had heterogeneity in different conditions, and the synergistic effect of the scheme is more significant in eastern regions, large cities, and the final industrial stage. Our findings offer innovative solutions for the integrated management of carbon emissions and air pollution and provide valuable insights for policymakers to enhance China's CETS. Integr Environ Assess Manag 2024;20:1112–1124. © 2023 SETAC Key Points: The carbon emissions trading scheme (CETS) led not only to the significant reduction by approximately 9.8% in carbon dioxide (CO2) emissions, but also effectively mitigated sulfur dioxide emissions by approximately 9.7% and particulate matter (PM)2.5 emissions by approximately 11.7%.This policy highlights the synergistic impact of reducing carbon emissions and air pollution.The effective emission reduction measures of CETS are focused on reducing energy intensity and upgrading industrial structure; the proper implementation of these measures can achieve significant synergistic emission reduction.Based on the heterogeneous analysis of the pilot scheme, the synergistic effects of the CETS are particularly significant in the eastern regions, large cities, and the final industrial stages.

Using an international sample of firms from 36 countries over the period 2002 to 2018, we investigate whether short sellers take firms' climate risk into consideration when making investment decisions. Our empirical results show that short sellers increase their short-selling interest in firms with high carbon emission intensity but shun good carbon performers. Furthermore, the effect of climate risk on short-selling interest is more pronounced for firms operating in countries or regions that have adopted an emission trading scheme (ETS) as well as in countries characterized by higher regulatory quality and greater media pressure. We also document that short sellers in countries with stringent carbon regulations, higher environmental awareness, and superior environmental performance are more sensitive to climate risk. Our channel analyses highlight that stock overvaluation and an opaque information environment are two potential motives for short-selling interest in carbon-risky firms. [ABSTRACT FROM AUTHOR]

This article examines a supply chain network that considers both economic and environmental factors. The network faces challenges related to multi‐item products and non‐homogenous vehicle types with different costs. Additionally, the production process involves multiple energy sources that emit different levels of air pollution. The main objective is to maximise profits while adhering to different carbon policies. To achieve this goal, the paper presents several supply chain models that are compared under different schemes: no carbon policy (basic one), carbon tax policy, carbon emission policy and carbon trading policy. These models were coded and solved to demonstrate their effectiveness for different conditions and scenarios. The results provide valuable insights for supply chain managers, enabling them to make well‐established decisions for executive planning. [ABSTRACT FROM AUTHOR]

We examine how environmental pressure influences board gender diversity. Drawing from resource dependence, strategic adaptation, and gender socialization theories, we develop and test the prediction that firms with worse environmental performance have a higher likelihood of increasing their board gender diversity following a rise in environmental pressure. Focusing on the third phase (2013–2019) of the European Union Emission Trading System (EU ETS), we exploit the unexpected increase in emission prices after the European Council's (EC) intervention in 2017 as a quasi‐natural experiment bringing heightened environmental pressure to firms. Our baseline sample consists of 182 polluting firms in 20 different EU ETS‐covered countries. In line with our main hypothesis, we find that board gender diversity increases with firms' industry‐adjusted levels of pollution in the post‐EC intervention period, with the effect being particularly pronounced for firms with a higher exposure to emission prices and lower diversity levels. Inconsistent with a window dressing explanation, highly polluting firms replace incumbent male board members with highly qualified women. Our findings, which survive several robustness tests, suggest that more stringent environmental regulation drives social and governance changes at top corporate levels. [ABSTRACT FROM AUTHOR]

With the increasing requirements for environmental protection, authorities have enacted different carbon policies to promote sustainable practices. This study considers the competition among different manufacturers and multiple demand markets in the supply chain network. We examine and compare their equilibrium decision conditions under three common carbon policies: carbon cap, carbon cap‐and‐trade, and carbon tax. Results suggest that under lower carbon caps, manufacturers greatly reduce their carbon emissions by reducing production quantities, which causes a decrease in profits. However, an appropriate carbon cap size can not only motivate manufacturers to reduce carbon emissions but also improve their profits. Under a certain price for carbon credit, the effectiveness of a carbon cap‐and‐trade policy is similar to that of a carbon cap policy, but it has more flexibility. Carbon tax is effective, but it brings more tax burden to manufacturers. We provide implications for companies to optimize their production methods to achieve sustainability. [ABSTRACT FROM AUTHOR]

There is still considerable resistance against carbon pricing — i.e. carbon taxation or cap-and-trade — in the social and policy sciences. We review its main arguments and conclude that they are not supported by the theoretical and empirical literature on instrument performance. Critics are also unable to offer alternative and feasible instruments that limit free riding in climate solutions and perform better on main evaluation criteria, namely effectiveness, efficiency, equity, and global-harmonization potential. Their argument that carbon pricing meets strong political resistance is countered by its widespread implementation already and by its ability to compensate inequitable impacts. We argue that overcoming unsubstantiated criticism on carbon pricing will lead to more consistent advice from policy experts to politicians, thus improving the feasibility of, and accelerating progress towards, globally harmonized and stringent climate policy. All in all, it might be more widely acknowledged that the remarkable feature of carbon pricing is that, if well implemented, it has a great number of advantages and few disadvantages. Rather than weakening political support by criticizing carbon pricing, critics would contribute more productively to effective global climate policy by defending proper and uniform implementation of it.

We study how the implementation of emissions trading systems (ETSs) impacts emissions reductions and the usage of renewable energy using a panel sample of the largest 100 countries worldwide. Exploiting cross-country variations in ETS implementations, we show that ETS adoption materially reduced greenhouse gas (carbon dioxide) emissions by 12.1% (18.1%). Moreover, ETSs reduced overall emissions by cutting the usage of fossil fuels such as coal by 23.70% while boosting the usage of renewable energy by 61.59%, on average. In contrast, introducing carbon taxes has a less effective impact on emissions reduction. It fails to boost the usage of renewable energy, though elevating tax rates and expanding tax coverage may help enhance the efficacy of carbon taxes.

Digital transformation, as a significant shift in optimizing enterprise resource allocation and enhancing information connectivity, offers the opportunity to stimulate the endogenous dynamics of corporate green governance. Employing a sample of 3,002 listed companies in China, a fixed-effects model, and the entropy power method to formulate a green governance index system, this study examines how digital transformation affects corporate green governance concerning carbon peaking and carbon neutrality objectives. According to these findings, the implementation of the digital transformation improves corporate green governance, each unit increase in digital transformation correlates with a 1.91% enhancement in green governance. Moreover, an examination of the mechanisms shows that green governance can be promoted by addressing information asymmetry and enhancing operational efficiency. Additionally, the association between corporate green governance and digital transformation is moderated favorably by strategic aggressiveness. Furthermore, our results indicate that digital transformation contributes significantly to the advancement of green governance within enterprises located in areas with high digital financing and strong technology integration capacities. Digitalization has a stronger effect on promoting green governance for enterprises in pilot regions than in non-pilot regions in terms of carbon emission trading. This study not only assists enterprises in elucidating the developmental trajectory of digital transformation amid carbon peaking and carbon neutrality goals but also provides a reference for decision-making on how digital technology can empower corporate green governance and promote sustainable economic growth.

Carbon emissions trading policies play a crucial role in facilitating the transition to high-end products within high-carbon enterprises. Nevertheless, current empirical analyses of the carbon emissions trading market exhibit a lack of precision and are susceptible to bias in their findings. Limited research has been conducted on the influence of product quality as a potential constraint on the impact of carbon trading on product bargaining power. This study presents a double-difference model utilizing data on emission-control enterprises in China's carbon market to examine the influence of the carbon emissions trading mechanism on the bargaining power of high-carbon products. Empirical analysis is conducted using financial data from listed companies in China spanning the years 2010 to 2020. The findings indicate that the implementation of carbon emissions trading policies has a dampening impact on the product bargaining power of high-carbon enterprises. Moreover, carbon emissions trading policies have heterogeneous effects on the product bargaining power of high-carbon firms with different life cycles, with mature high-carbon firms receiving a boost and declining high-carbon firms receiving a dampening effect. Mechanism test finds that the incomplete transmission effect of cost shocks resulting from carbon emissions trading policies has negatively affect the product bargaining power of high-carbon enterprises. Further research finds that product quality is a key factor in determining the effect of the carbon emissions trading policy, and that the impact of the carbon emissions trading policy on the bargaining power of products of high-carbon firms takes on a "U" shape due to product quality. Once the product quality exceeds the bottleneck value of 0.5956, the policy significantly increases the bargaining power of products. The study confirms that the establishment of carbon markets can effectively increase the bargaining power of superior products. These results offer a comprehensive theoretical and practical foundation for nations to advance the development of carbon markets and facilitate the achievement of sustainable development by high-carbon enterprises.

Facing the double constraints of the "double carbon" target and high-quality economic development, carbon trading policy is an important tool for realizing the emission reduction commitment; based on the perspective of microenterprises, the specific mechanism and spatial effect of carbon trading policy still need to be evaluated. Taking China's carbon emissions trading pilot as a quasi-natural experiment, this paper empirically investigates the impact of carbon trading policy on the carbon emission intensity of pilot enterprises and its mechanism of action, and its impact on the carbon emission intensity of neighboring enterprises, based on the multi-temporal double-difference model, moderating effect model, and spatial Durbin model with the A-sharelisted enterprises in the period of 2009-2019 as the samples. It is found that: 1) Carbon trading policy will reduce the carbon emission intensity of enterprises to different degrees, and there are significant differences under different ownership types, degrees of marketization and the level of digitization. 2) Under the influence of environmental uncertainty, ESG disclosure will weaken the effectiveness of carbon emission reduction in the pre-pilot stage of the policy; with the gradual improvement of the carbon trading policy and ESG disclosure mechanism, ESG ratings will positively regulate the inhibitory effect of the carbon trading policy on the carbon emission intensity of enterprises through multiple paths. 3) Carbon trading policy effectively reduces multiple negative spillovers through the demonstration effect and competition effect of neighboring enterprises, driving the carbon emission reduction behavior of non-pilot enterprise. The research in this paper enriches the research paradigm of carbon emission intensity influencing factors, provides reference suggestions for the government to improve its policies, and better contributes to the realization of the "dual-carbon" vision in China as soon as possible.

Against the backdrop of climate change becoming a global hot topic, global carbon emissions continue to grow. As the world's largest developing country, China is facing increasingly severe pressure to reduce emissions in its development. At the same time, in the current context of low-carbon transformation, the country has also begun to vigorously promote the carbon emission trading market. In the development process of China's carbon emissions trading market, there are still problems such as uneven data quality, insufficient data accuracy and standardization, which affect the normal operation of the carbon emissions trading market. Therefore, while the carbon emissions trading market is rapidly developing, it is necessary to establish a comprehensive carbon emissions data management system. This article analyzes the problems and future development directions of China's carbon emission data management system, and designs an overall design scheme for a carbon emission data management system based on multi-source data fusion. Through comparative experiments of UOS (ultimate Oscillator) indicators, it was found that the data transmission capacity of the carbon emission data management system designed in this paper with multi-source data can gradually improve the UOS value through continuous use. At the end of the experiment, it obtained a UOS value of up to 91.23%, far exceeding the efficiency of traditional data transmission. [ABSTRACT FROM AUTHOR]

The Chicago Climate Exchange (CCX), which operated from its launch in 2003 to its sale to the Intercontinental Exchange (ICE) in 2010, was the world's first and still only cap-and-trade system covering all six major greenhouse gases (GHGs) Membership in CCX was voluntary, but all emissions reduction commitments, auditing and trading rules were mandatory via a legally binding civil contract, a first in history. The goal was to use a market-based solution to reduce carbon emissions at the lowest possible cost, and CCX drew more than 400 members to its system at the time when there were no mandatory greenhouse gas reduction policies in place in the United States or abroad. The question is why did major emitters, market participants, cities, states and other entities choose to act to use emissions trading to mitigate climate change when there was no requirement for them to do so? This paper examines the question, suggesting that the CCX model embodied aspects of theories put forward by economists such as Knetsch, Buchanan and Coase and that CCX could serve as a bridge between theory and practice for economists interested in further study of markets and public goods. The paper also highlights the influence of CCX as a rules-based single coherent entity that significantly influenced the development of what has become known as the "voluntary carbon market" (VCM), while being quite different from the VCM. In the process of building its operations, CCX also generated a number of firsts, including creating the world's first GHG registry, and inventing the world's first carbon-based tradeable unit, the carbon financial instrument (CFI), equivalent to one hundred metric tonnes of CO2e, and spearheaded a landmark joint venture in China that created China's first pilot carbon market, the Tianjin Climate Exchange (TCX). Given the start-up nature of CCX, its significant global membership and international coverage is notable. The paper suggests the evolution and growth of CCX represents perhaps the largest ever experiment in behavioral economics relevant to contemporary climate change and environmental issues, yet one of the least understood and studied other than by those who had been involved. The paper will explore the origins, rationale, structure, framework, rules and legacy of CCX, including recommendations based on lessons learned, as the world faces the compounding crisis of climate change and the urgency of meeting the objectives of the Paris Agreement to stem climate change, the myriad of disparate Net Zero pledges to reduce emissions, and additional international environmental agreements aimed to protect biodiversity and other natural systems and processes.

In the European Union, greenhouse gas emissions statistics indicate only a slight decreasing trend over the last number of years in emissions from agricultural sources. Unless drastic action is taken in other sectors, the European Union's 2030 and subsequent climate targets are unlikely to be met without greater reductions made in agricultural emissions. The policy instruments aimed at reducing agricultural emissions that are currently in place have proven to be ineffective; therefore, there is a need to look for new approaches towards bringing agricultural emissions down faster and farther. One obvious new approach is to integrate agricultural emissions into the European Union Emissions Trading System, which, so far, has proven very successful in reducing greenhouse gas emissions in the energy and industrial sectors. Hardly any attention has been paid in the scholarly legal literature to the question of integrating agricultural GHG emissions into emission trading systems. This article seeks to fill this gap. This paper presents the concluding findings of a Dutch Research Council-funded research project that aimed to assess whether and under what conditions the European Union Emissions Trading System could play a role in compelling the agricultural sector to reduce its greenhouse gas emissions. We answered this question by looking at lessons learned from existing examples in the world of market-based approaches to integrating agriculture into emission reduction schemes. To do this, we performed an ex-post assessment of three of the very few examples that exist in the world of such schemes in Canada, California, and Australia, followed by an ex-ante assessment of the prospect of including agricultural emissions under the European Union Emissions Trading System based on the practical experiences of those examples. In the ex-ante study, we evaluated how such inclusion could work, either indirectly, through allowing on-farm offset programs to reward increased carbon sequestration, or directly, by requiring farmers and/or other actors in the agricultural sector to surrender allowances for their direct emissions. As lawyers, we focused mainly on the legal considerations of such a proposition. Having conducted both the ex-ante and ex-post assessments, we conclude that introducing stricter legal instruments of one form or another that will reduce agricultural greenhouse gas emissions and increase carbon removal on agricultural land seems necessary for the European Union if it is serious about achieving its commitments under the Paris Agreement and meeting its obligations under its own Climate Law. The project makes a novel contribution to the legal scholarship in concluding that the most viable starting point for such stricter legislation would be to include methane and nitrous oxide emissions from livestock keeping and synthetic fertilizer use, respectively, under the European Union Emissions Trading System. To start with, this could be conducted by obliging meat and dairy processors and synthetic fertilizer producers to surrender allowances for the on-farm emissions associated with their products. This could be complemented by introducing a voluntary, but still highly regulated, carbon credits scheme that could encourage and reward farmers for reducing their own emissions and for transitioning to net-zero, and overall, more climate-resilient and environmentally friendly farming practices. Such credits could be offered for sale on the private carbon market as well as to Member State governments and the European Commission (through, for example, the Common Agricultural Policy, State Aid schemes, or the Innovation Fund).

China is constantly seeking rapid, high-quality growth in order to meet its carbon peaking and neutrality goals. Approximately 40% of China's carbon emissions come from the electric power industry, which is beset by issues of poor efficiency and excessive emissions. Thus, it is essential to determine if environmental restrictions increase economic benefits total factor productivity while still preserving the environment. We use the Quasi-DID method to examine the impact of carbon emissions trading scheme on firm-level total factor productivity of electric power companies. The findings demonstrate the following: (1) carbon emissions trading scheme considerably impedes total factor productivity development; (2) the primary cause of this detrimental impact is the need for additional improvements in marketization since green innovation is still in its infancy; (3) additional study indicates that law enforcement's heterogeneity is what affects this restriction. Our research may both enhance the Chinese carbon emissions trading scheme's effectiveness assessment framework and point out several potential avenues for high-quality growth. [ABSTRACT FROM AUTHOR]

As a voluntary individual carbon trading mechanism, the carbon generalized system of preferences (CGSP) aims to promote individuals' active practice of low-carbon behaviors through the incentive model of 'who reduces emissions, who benefits from the practice.' It is an extension and expansion of the carbon emission trading mechanism to the individual level, and it is of great significance to evaluate the carbon emission performance of this policy to tap the emission reduction potential of individual society and enrich the environmental policy tool system. Based on the quasi-natural experiment of the implementation of the CGSP in Guangdong Province in 2015, this paper empirically evaluated the policy effect of the CGSP in improving regional carbon emission performance by using the synthetic control method and provincial panel data from 2005 to 2021 and further explored the mechanism of the policy effect. The results showed that the implementation of the CGSP was conducive to improving regional carbon emission performance and promoting the reduction of regional total carbon emissions, per capita carbon emissions, and carbon emission intensity. In the seven years from 2015 to 2021, the policy intervention reduced the total carbon emissions of Guangdong Province by an average of 40.94 million tons, per capita carbon emissions by 0.294 tons, and carbon emission intensity by 0.312 tons/10 000 yuan. This conclusion was still valid after the placebo test, ranking test, and test excluding other policy interferences. Further intermediary tests showed that the CGSP acted on regional carbon emissions through two intermediary pathways: promoting public green travel and reducing electricity consumption. But the mediating path with energy consumption as the mediating variable did not hold. The study reveals the effectiveness of both incentivized and voluntary individual carbon trading mechanisms in environmental governance and makes the following policy recommendations: ① We should pay attention to the emission reduction potential of social individuals on the consumer side, gradually incorporate individual carbon trading mechanisms into carbon emission reduction governance, and encourage local governments to apply and develop the CGSP according to local conditions. ② In the design of CGSP, it is necessary to improve the incentive mechanism in low-carbon travel scenarios and low-carbon life scenarios and improve the convenience of public participation in emission reduction. ③ It is necessary to develop a more scientific carbon-inclusive quantitative verification methodology and build a comprehensive carbon trading system covering the public and industrial enterprises.

The Chinese government aims to balance employment stabilization and emissions reduction when it initiates an emissions trading scheme (ETS) to control carbon emissions. However, the policymakers should not neglect the role of imperfectly competitive market structure and market power from incumbent firms. In view of this, classical framework of Berman and Bui's (2001) is extended in this paper to clarify the theoretical mechanism of employment effect of the ETS considering firm-level market power. In addition, based on the firm-level panel data from 2008 to 2019 of China, the employment effect of each pilot ETS is measured with the method of difference-in-difference-in-differences. Then a moderating effect model is established to verify the role of firm-level market power on the heterogeneous employment effect among the pilot ETSs. Moreover, the employment effect is further decomposed to evaluate the influential mechanism from the perspective of firms' strategic behavior. It is found that there is negative employment effect of China's ETS policy, due to the significant moderating role of firm-level market power. This decrease in labor demand is mainly dominated by a negative output effect rather than a positive substitution effect because strategic allowance sellers with stronger market power tend to hire fewer employees to reduce carbon emissions by controlling production scale. However, the heterogeneity of policy effects resulted by market structure is also identified in different pilot regions. Employment dividend has been found in Beijing and Tianjin where strategic allowance buyers manipulate the carbon market and hire more employees to consolidate their market power. Therefore, policymakers should improve the design of the ETS to overcome the adverse employment effect duo to the region-specific market structure. [ABSTRACT FROM AUTHOR]

Fossil-based natural resources are carbon-intensive, and over-reliance on them often leads to persistent high carbon emissions at national or regional levels, resulting in the carbon curse. Based on the panel data of 114 resource-based cities in China from 2007 to 2020, this paper examines the carbon curse and solutions for these cities from the perspectives of total and intensity of carbon emissions. The results show that: Firstly, due to the different stages of urban development, resource endowment, degree of resource dependence, and policy background, there is a heterogeneity of carbon curse in China's resource-based cities. Secondly, the carbon emission trading policy can effectively mitigate the carbon curse in China's resource-based cities, and the robustness tests demonstrate the validity of this finding. Thirdly, under the carbon emission trading policy, industrial structure upgrading and digital transformation can play a secondary moderating role in resolving the carbon curse in resource-based cities, further strengthening the inhibitory effect of the carbon emission trading scheme on the carbon curse. In contrast, green technology innovation exhibits no enhancement in the impact of the policy. These findings contribute to the existing research on the carbon curse, offering valuable insights and policy implications for effectively addressing this challenge. [ABSTRACT FROM AUTHOR]

• Carbon emissions trading, industrial structure upgrading and green development are integrated into a unified analytical framework. • Taking the carbon trading mechanism as the moderating variable can effectively combine the method of comparative static analysis. • Whether in the long term or the short term, the carbon pilot policy and the industrial structure upgrading policy implemented at the same time will have excess benefits. • When factor flow between cities is considered, excess benefits still exist significantly. Clarifying the influence mechanisms of carbon emissions trading scheme (ETS), industrial structure upgrading (ISU), and green development is of great theoretical and practical significance. Existing studies have only focused on the role of ETS or ISU on green development and have not included them in an analytical framework. The DID model and the moderating effect model are therefore combined in this work to to explore how the ETS will affect the link between ISU and green development throughout the period of 2008 to 2019 using panel data from 271 Chinese cities. Through a series of robustness and endogeneity tests, we find that: (1) ETS can significantly moderate the U-shaped relationship between ISU and green development, and this impact is significant in both the long and short term; (2) When ETS and ISU are implemented at the same time, the effect of the combined actions is greater than the sum of the effects of the two policies implemented separately, which means that the combined actions has excess dividends; (3) ETS and ISU have significant direct effects and spatial spillover effects on green development, and the excess dividends of combined actions also exist significantly at the spatial level. The research results of this paper provide an important theoretical and empirical basis for establishing the combined actions of ETS and ISU. [Display omitted] [ABSTRACT FROM AUTHOR]

This paper assesses the feasibility of India achieving its stated objective of getting to net zero carbon emissions by 2070 and outlines a possible strategy for the next 10 years consistent with this goal. It recommends a combination of price-based measures and several sector-specific interventions. The ideal price-based measure would be a carbon tax. This may not be feasible for various reasons, but in its absence a well-designed emissions trading system, as described in the paper, could make a major contribution in reducing emissions. On sectoral interventions, the critical areas over the next 10 years would be (i) accelerated expansion of various forms of renewable energy capacity, which will require several policy changes, (ii) electrification of transport, and (iii) a shift from private to public transport in urban areas and from road to rail for freight. Action will also be necessary in other sectors such as industry, agriculture, and buildings, but a detailed strategy for these may take more time to put in place. Since responsibility for action in all these areas is spread across different ministries in the central government and, in many cases, state governments, evolving an internally consistent and cost-effective strategy will present a major challenge. There is a case for setting up a high-level commission chaired by the Prime Minister to approve a national strategy. The paper estimates that the additional investment needed to make this transition will be about 2 per cent of India's GDP by 2030, much of which will have to come from additional public and private savings. In this context, some form of carbon pricing would help generate additional revenue. [ABSTRACT FROM AUTHOR]

As carbon neutrality gains momentum, industries worldwide are navigating the challenges and opportunities posed by sustainability goals. This article delves into the strategies undertaken by airlines and maritime companies to achieve carbon neutrality by 2050 in the European Union (EU). The aim of the research is to explore how the aviation and maritime industries in Europe can effectively transition towards carbon neutrality by 2050, considering their similar technological challenges and opportunities. The objective of this research was to identify and compare currently utilized sustainability initiatives in aviation and maritime companies. The focus is on new insight from airline and maritime companies concentrating on their sustainability practices. Common hurdles, innovative solutions, and shared opportunities in the pursuit of environmental sustainability are explored. The selected research method was qualitative research, which was conducted with in-depth and semi-structured interviews and content analysis. Interviews were conducted with airline company and association representatives and maritime company, research, and education experts. The content analysis was based on sustainability reports and sustainability sections of annual reports. Key findings were synthesized into a theoretical framework and this research explores practical initiatives for a sustainable transformation process. The call to reduce carbon emissions has been initiated by the EU affecting the transportation sector, particularly aviation and maritime industries where the path to achieving carbon neutrality is constrained by significant technical limitations. Despite these challenges, both sectors share a unified objective according to EU climate targets. Both the aviation and maritime industries face challenges on the path to carbon neutrality. Airlines struggle with the limitations of current aviation technology, hindering the feasibility of large-scale technological advancements. Similarly, maritime companies confront regulatory complexities and infrastructure limitations in the adoption of alternative fuels and emission-reduction technologies since the commonly used tactics of reducing fuel consumption by optimizing speed, routes and scheduling are no longer adequate ways and the energy needs of the shipping industry cannot be met only with battery technology. These challenges offer opportunities for innovation and collaboration. Investments in research and development are driving advancements in electric and hydrogen aircraft, while the maritime industry is also trying to find hydrogen-based solutions for greener development, but the technologies are not widely available. This leads towards combining bio-oils and technological innovations related to the fleet. Case study 1 sheds light on airline sustainability in Europe, revealing strategies and initiatives that European airlines are currently utilizing in their sustainable transformation journey. Case study 2 explores different means of achieving carbon neutrality in the maritime industry, in particular the potential of common reed (Phragmites australis) as a carbon offset tool for reaching net zero. Both industries are making significant strides towards carbon neutrality through a combination of technological innovation, operational efficiencies, and strategic partnerships. Towards green horizons as transport industries converge on the path to carbon neutrality. [ABSTRACT FROM AUTHOR]

This study investigates the competitive issues of the newsvendor problem with product substitution under the carbon cap-and-trade system. Building on existing research, this paper introduces the carbon cap-and-trade system under uncertain market demand and considers that the original equipment manufacturer (OEM) can choose to procure raw materials from the contract manufacturer (CM), with both final products being substitutable. Furthermore, we explore the different substitution relationships between OEM and CM products under both pure competitive and co-opetitive modes. For this problem, decision models are developed for various scenarios, and optimal solutions satisfying given conditions are provided. We find that in one-way substitution, under pure competition, an increase in the OEM's (or CM's) green investment and substitution rate only leads to an increase in OEM's (or CM's) yields, while an increase in the OEM's (or CM's) green investment does not necessarily reduce CM's (or OEM's) yields. In the co-opetitive mode, an increase in the substitution rate and green investments of both manufacturers may lead to an increase in the yields of both manufacturers. Furthermore, an increase in carbon trading prices does not necessarily inhibit the manufacturer's yields. Moreover, we find that under the same competition mode, under certain conditions, two-way substitution between OEM and CM can bring better profits to both manufacturers and the entire supply chain. When the two modes are in the same substitution scenario, and the CM cannot substitute for the OEM, the optimal decisions and total supply chain profits of the two modes are equal. Finally, through numerical analysis, we find that neither mode is necessarily optimal when CM can substitute for OEM. Additionally, it is observed that when the same mode is in different substitution scenarios, total supply chain profits may be enhanced in the presence of product substitution.

We construct a two-country trade model where emissions are an input in production and generate cross-border pollution. We examine the strategic incentives of an active regulator who sets a binding level of emissions in production. We show that, in the presence of terms of trade and emission leakage strategic motives, tighter regulation can mitigate emission leakage, reduce global pollution, and improve a country's welfare. This result and the corresponding policy implications depend on the relative magnitude of emissions intensities of goods between sectors and on their relationship in production and consumption.

The goal of this paper is to discern whether environmental policy stringency discourages inbound tourism in the G7 countries. The analysis is based on second-generation panel data methods in consort with the panel quantile regression approach. The findings document that environmental policy stringency plunges inbound tourism across all quantiles. Moreover, the impact of environmental policy stringency is relatively strong at higher quantiles compared to middle and lower quantiles, while the analysis reports that per capita global GDP escalates inbound tourism at all quantiles, whereas both inflation and the real effective exchange rate plunge inbound tourism. Finally, this study proposes certain policy recommendations to promote tourism. The results also survive certain robustness tests. They also imply that the countries under consideration need to adopt special measures to promote tourism, apply strict environmental control measures, while tourists should be given incentives to offset the detrimental impact of environmental regulations. Finally, the tourism-related firms should be given higher emissions permits through an emissions trading scheme, which lowers the cost of tourism, as well as tax exemptions on their imports.

We investigate green technology unilateral licensing strategies between two competing manufacturers under carbon cap‐and‐trade policy. We construct Nash game models and compare the optimal strategies in the unilateral licensing situation with the no‐licensing situation. Comprehensive numerical experiments are taken to investigate the influence of some key parameters on optimal decisions. Our findings show that the green technology unilateral licensing strategy may benefit consumers; when green technology improvement is high, manufacturers tend to take the unilateral licensing strategy to obtain more profits; when initial unit carbon emission difference is moderate or large, the optimal strategy is that the manufacturer with lower level of green technology acts as the licensor; green technology unilateral licensing strategy may not necessarily reduce all manufacturers' total carbon emissions; only when green technology improvement is high, the unilateral licensing strategy is beneficial to environmental protection.

Although both the carbon emission trading market (CETM) and government regulatory actions promote companies' green technology innovation (GTI), little research has considered whether such innovation is substantial. In this paper, we categorize companies' GTI strategies into substantial innovation and strategic innovation. Considering market powers, the heterogeneity of companies, and the mutual influence of governments and companies, we construct a tripartite evolutionary game model that involves large and small companies and the government and conduct a simulation utilizing data on China's CETM. Our findings reveal that carbon trading prices, innovation subsidies, and the government's verification mechanism are the main factors that affect companies' choices regarding substantial innovation. However, the current carbon trading prices in China are relatively low, and companies are still likely to choose strategic innovation. Moreover, we find that when the substantial innovation of large companies exerts a greater impact on the product revenues of small companies, small companies are more inclined to choose substantial innovation. Therefore, in an effort to induce companies to choose substantial innovation, the CETM should play the leading role in this situation, and the government should implement different innovation subsidies and improve the verification mechanism.

Considering customers' preferences for low‐carbon products, the paper delves into the short‐run and long‐run repetitive game involving three oligopolistic manufacturers engaged in the production of new energy vehicles (hybrid electric vehicles [HEV] and battery electric vehicles [BEV]) and conventional fuel vehicles (FV) within the framework of a carbon cap‐and‐trade policy (CaT). In the short‐run game model, this study explores the optimal decision of oligarchic manufacturers and analyzes the efficiency of the supply chain in the context of cooperation and non‐cooperation. In the long‐run repetitive scenario, the article examines the optimal decision of the manufacturer, assuming rational economic behavior aimed at maximizing individual profits within a non‐cooperation game strategy. Finally, the paper investigates the elements that influence the efficiency of the supply chain. The results reveal that (1) fuel vehicles possess greater flexibility in adjusting parameters compared to the other vehicle types; a judicious increase in manufacturers' price adjustment parameters in the stability domain is beneficial to their respective profits and enhances the overall supply chain profitability. (2) Maintaining customers' preference for low‐carbon products within a reasonable range is crucial for the mutual benefit of all manufacturers. (3) The government needs to allocate more carbon emission limits to fuel vehicle manufacturers in order to improve supply chain efficiency. [ABSTRACT FROM AUTHOR]

Emissions trading scheme (ETS) is a market-oriented measure to promote green transition. In order to determine systemic risk among ETS pilots and industrial supply chain in China, this study applies a financial network approach on a system consisting of 7 emission allowances and 27 commodities. The empirical findings confirm that ETS poses transition risks to industrial supply chain by creating new information channels between emission allowances and commodities. Such channels are generated by the extensive financial connections within the ETS-commodity system. The degree of financial connection dynamically responds to shocks from institutional events of ETS, transaction adjustments for commodities, and extreme risk event like COVID-19. Analysis of connection structure shows that most of the products within the ETS-commodity system differ in the ability to generate financial connections. The bidirectional connection feedbacks between them and their connectors exhibit asymmetry. Several centrality indicators also screen out systemically important products from multiple scales. The findings could have policy implications for related authorities, manufacturers and investors. [ABSTRACT FROM AUTHOR]

This study investigates the impact of financial development and foreign direct investment (FDI) on CO2 emissions, with a special focus on carbon pricing (emissions trading and taxing) in 57 developed and developing economies between 2000 and 2017. Using an eight-fold financial development construct for the first time, we find that financial depth in institutions negatively (positively) affects the CO2 intensity of developed (developing) economies, while financial access to institutions has a negative impact in both types of economies. Financial depth (stability) in markets negatively affects developing (developed) economies' CO2 intensity, while financial access to markets increases (decreases) CO2 intensity in developed (developing) economies. Moreover, inward FDI stock quality (a net FDI position) increases (reduces) CO2 intensity in developing (developed) economies. Finally, we document that carbon pricing in developed economies helps reverse the positive effect of inward FDI quality on CO2 intensity, implying that a such policy helps those economies attract climate-friendly FDI. Our study reveals the implications of the reduction of CO2 emissions placing the focus on both financial development and FDI fully and together for the first time. [ABSTRACT FROM AUTHOR]

Global maritime emissions, a 3% contributor to greenhouse gases, anticipate a surge of 90–130% by 2050. Regulatory challenges persist due to international governance gaps. Legislative strides, including the EU Emission Trading System, highlight global efforts. In the U.S., despite legislative commitment, consensus hurdles impede cross-regional carbon management. Prevailing top-down emissions estimation methods warrant scrutiny. This paper unveils U.S. maritime emissions intricacies, focusing on carbon accounting, transfer, and compensation for cargo and tanker vessels. Leveraging AIS data (2018–2022), an activity-based/bottom-up approach navigates emissions calculations, aiming to reshape understanding and foster strategic reductions. The study bridges gaps in U.S. maritime emission research, promising insights into transfer and compensation dynamics. By concentrating on high-impact vessel types, it contributes to emissions mitigation strategies, steering towards a sustainable U.S. maritime future. [ABSTRACT FROM AUTHOR]

Investigating the impact of carbon emissions trading policy and elucidating the underlying mechanisms are crucial for enhancing policy effectiveness and refining related systems. This study examines the impact of carbon emissions trading policy by constructing a difference-in-difference model utilizing unbalanced panel data from China's provinces spanning the period from 2005 to 2019. Additionally, a mediating effect model is employed to delve into the underlying mechanisms. The key findings are as follows: Firstly, the implementation of carbon emissions trading policy has a notable inhibitory impact on carbon emissions. Secondly, both the upgrading of industrial structure and the reduction of energy intensity play mediating roles in carbon emissions reduction. However, the development of clean energy industries does not exhibit a significant mediating effect. In conclusion, this study offers policy recommendations aimed at facilitating carbon reduction. These include enhancing the market-based trading mechanism for carbon emissions, optimizing and upgrading industrial structures, fostering innovation in green and low-carbon technologies, and promoting the development and utilization of clean energy.

We highlight a coordination problem between the EU Emissions Trading System (ETS) and the EU's offshore renewable energy strategy. We exemplify this coordination failure by analyzing carbon leakage effects associated with Denmark's planned North Sea energy island. The Danish energy island project will not start production before 2033, implying a long interval between project announcement and production. Using a dynamic model of the EU ETS, we show that the large time gap between announcement and production likely results in a 'Green Paradox', where the energy island increases aggregate EU ETS emissions. The mechanism leading to the emission increase is complicated and works through the Market Stability Reserve (MSR). The estimated 2050 leakage rate is 145 percent in our main scenario and not below 100 percent in any alternative scenario. We discuss how to improve the climate benefits of the energy island or similar large-scale renewable energy projects. This includes possible revisions to the EU ETS and the role of Power-to-X technologies. There is a coordination failure between the EU ETS and the EU's offshore renewable energy strategy, as projects intended to fulfil the offshore strategy are likely to result in substantial carbon leakage due to the EU ETS. In ETS-covered sectors, there are averse leakage effects associated with emission abatement projects with significant time lags between project announcements and emission abatement like the Danish North Sea energy island. For the North Sea energy island and similar projects, leakage effects can be diminished through policies that mitigate the impact on EU ETS allowance demand. The coordination failure can be eliminated by removing MSR cancellations or the entire MSR mechanism while adjusting the emission cap to hold expected emissions constant. However, removing MSR cancellations amplifies leakage effects for abatement projects with short time lags between announcements and emission abatement, which currently have weak leakage effects due to MSR cancellations.

With the emergence of climate-themed trade measures, it is increasingly crucial to promote the globalization of China's national carbon emissions trading system (C-ETS) with Chinese characteristics in a proactive, systematic, and orderly manner. Existing studies have largely focused on 'point-to-point' responses to international pressure and/or on the construction of a domestic carbon ETS primarily for institutional self-sufficiency. Altogether, the current literature may fail to sufficiently inform authorities, particularly on how to effectively address the urgent need to safeguard economic and trade interests and, further, on how to systematically accommodate the strategic need to enhance low-carbon competitiveness for the future and to assume a more active role under future global governance. Therefore, this study analyzes the three major challenges faced by the C-ETS systematically and, from the interdisciplinary perspectives of law and economics, identifies the theoretical nature and guiding principles of globalizing the C-ETS. Furthermore, based on an analysis of institutional background (i.e., international law and associated carbon-themed guidelines) and practical basis (i.e., associated domestic and international practices and the status quo of carbon-themed global competitions), this study evaluates the technical feasibility, legal compatibility, economic co-benefits, and political desirability of various paths, identifies key areas and low-carbon standards, and further proposes three-stage paths. Ultimately, this study finds that:(1) From the perspective of climate trade policy linkages, the key to globalizing the C-ETS is to leverage China's economic and trade influences to systematically promote low-carbon standards thereof. (2) Differing from international practices, e.g., those of the EU, China's globalization emphasizes the dynamic interaction between climate justice and mitigation efficiency to better balance domestic and global interests as well as climate pledges and domestic industrial competitiveness. (3) Significant differences exist in the goals, implementing entities, and paths of globalization across different fields of mandatory and voluntary ETSs, intersections of trade and climate change mitigation, and mechanisms for sharing carbon costs. Altogether, this study provides theoretical rationale and policy suggestions for public actors at the national, regional, and city levels, particularly as to taking a more prominent role in future global climate governance. It further lays a theoretical foundation for private actors, such as Chinese enterprises, industry associations, and financial institutions, to engage in soft-law-governed global carbon governance.
