Climate change presents a fundamental challenge to the current global energy regime. Under the Framework Convention on Climate Change, the international community is developing the architecture of a policy response. Three serious flaws are examined: (a) the potential sacrifice of small island states, (b) the use of market-based policy measures to commodify the atmospheric commons, and (c) the substitution of carbon sequestration for meaningful reductions in energy use. The authors’ analysis of the politics of climate change, based on these (...) issues, suggests a new understanding of ecology is emerging—what they term postmodern ecology—in which a global environmental crisis is risked to secure the future of the world energy regime. An alternative, based on principles of sustainability and equity, is proposed that would require abandoning the global energy status quo. (shrink)

Enterprises are the market players for carbon reductions and carbon trading, and they are also the significant driving force in a low-carbon economy and society. Using the data of A-share listed companies from 2010 to 2016, this study uses a difference-in-differences model to examine the effects of the low-carbon city construction on corporate carbon reduction performance. Consistent with our hypotheses, we find that the low-carbon city construction promotes corporate carbon reduction performance. (...) Further analysis indicates that the policy effect is stronger for state-owned enterprises than non-state-owned enterprises. Moreover, environmental quality can affect the promotion of local government officials, which is more prominent in pilot low-carbon cities, and political promotion incentives significantly improve corporate carbon reduction performance. Furthermore, the highest emission reduction effects come in the fourth year after adopting a carbon reduction policy and are concentrated among the firms in the eastern region. Overall, our findings offer a new point view for a deeper understanding of the improvement of corporate carbon reduction performance, and provide microscopic evidence for the objective evaluation of the environmental effects of China's low-carbon city pilot policies.

The United States health care industry is the second largest in the world, expending an estimated 479 million metric tons (MMT) of carbon dioxide per year, nearly 8 percent of the country's total emissions. The importance of carbon reduction in health care is slowly being accepted. However, efforts to “green” health care are incomplete since they generally focus on buildings and structures. Yet hospital care and clinical service sectors contribute the most carbon dioxide within the U.S. (...) health care industry, with structures/equipment and pharmaceuticals ranking as the third and fourth highest emitters in the industry. Given the magnitude of health care carbon emissions—and the paucity of attention to the carbon of hospital care and clinical services—this essay identifies overuse of health care as a health threat with serious ethical implications, offers a data‐driven action plan for carbon reduction in health care, and provides practical suggestions for more sustainable health care delivery in the United States.

Carbon emission has negative externalities, which will cause severe natural and social problems. In recent years, more and more attention has been paid to carbon emission reduction issue both in academic and application fields. This paper aims to explore the impact of punitive carbon tax and incentive carbon emission reduction subsidy on economy and environment through the dynamic stochastic general equilibrium framework. The results show that both carbon tax and carbon emission (...) class='Hi'>reduction subsidy policies can help to reduce carbon emissions and to improve environment quality. In addition, carbon emission reduction subsidy has a positive impact on economy, while carbon tax has the opposite impact. It follows that the incentive carbon emission reduction policy is more conducive to the coordinated development of economy and environment. This research can be a guideline for the government to formulate carbon emission abatement policies from the perspective of coordinated development. (shrink)

In literature, the firm’s selection of dual-product strategy under cap-and-trade regulation and the optimal emission reduction decisions are not well studied, especially through an analytical approach. We develop a theoretic model to investigate the firm’s selection on three product strategies in the presence of cap-and-trade policy, including two single product strategies and a dual-product strategy, and identify two types of consumers: consumers with low-carbon preference and regular consumers. Our analysis shows that, in the absence of cap-and-trade policy, it (...) is optimal to adopt dual-product strategy, but in the presence of this policy, it is optimal to adopt dual-product strategy or low-carbon product strategy. Compared with ordinary product strategy, adopting a low-carbon product strategy or dual-product strategy benefits the firm under cap-and-trade regulation. The additional cost of producing low-carbon product has an impact on the firm’s product strategy selection under cap-and-trade regulation. When it falls below a certain threshold, it is optimal to adopt a dual-product strategy; otherwise, it is optimal to adopt a low-carbon product strategy. Our research can provide reference for firm’s decision-making and government’s policy formulation. (shrink)

Many companies offer their customers voluntary carbon ‘offset’ certificates to compensate for greenhouse gas emissions. Voluntary offset certificates are cheap because the demand for them is low, allowing consumers to compensate for their emissions without significant sacrifices. Regarding the distribution of emission reduction responsibilities I argue that excess emissions are permissible if they are offset properly. However, if individuals buy offsets only because they are cheap, they fail to be robustly motivated to choose a permissible course of action.This (...) suspected lack of robust motivation raises both pragmatic questions about the functioning of offsetting schemes and moral questions about the worth of such unstable motives. The analysis provided here also has wider implications for the normative analysis of partial compliance and ‘many hands’ problems, especially for those cases where compliance levels and costs interact.

With the implementation of national carbon emission reduction policies and the development of online shopping, manufacturers are making low-carbon efforts and selling products through dual channels. This paper constructs a dual-channel supply chain decision-making model composed of low-carbon emission reduction manufacturers and retailers and studies the optimal decision-making problem of the supply chain under subsidies by the government based on emission reduction R&D and per unit product emission reduction. The research results show the (...) following: when the government subsidizes emission reduction R&D, the emission reduction will have an impact on retailers’ optimal prices, manufacturers’ optimal wholesale prices, and optimal direct sales channel sales prices. The profit of the manufacturer increases with the increase in carbon emissions, and the profit of the manufacturer increases to a certain level and then appears to decline. When the government adopts a subsidy method based on the emission reduction per unit product, the manufacturer’s wholesale price and the selling price of direct sales channels, as well as the retailer’s own optimal price, will increase with the increase in emission reductions. Retailers’ profits will increase linearly with the increase in carbon emissions. Manufacturers’ profits will first increase in a straight line and then increase in a curve. (shrink)

In the rapidly expanding literature on the ethics of climate engineering, a lot has been made of the fact that stratospheric aerosol injection would for the first time create a world whose climate had been intentionally shaped by deliberate human decisions. Intention has always mattered in ethics. Due to the importance of intention in assigning culpability for harms, one might expect that the moral responsibility for any harms created during an attempt to reconstruct the global climate using stratospheric aerosols would (...) be considerable. This article investigates such an expectation by making a comparison between the culpability for any unintended harms resulting from stratospheric aerosol injection and culpability for the unintended harms already taking place due to carbon emissions. To make this comparison, both types of unintended harms are viewed through the lens of the doctrine of double effect. The conclusion reached goes against what many might expect. The article closes by suggesting that a good way to read this surprising conclusion is that it points toward the continuing moral importance of prioritizing emission reductions. (shrink)

The US healthcare industry emits an estimated 479 million tonnes of carbon dioxide each year; nearly 8% of the country’s total emissions. When assessed by sector, hospital care, clinical services, medical structures, and pharmaceuticals are the top emitters. For 15 years, research has been dedicated to the medical structures and equipment that contribute to carbon emissions. More recently, hospital care and clinical services have been examined. However, the carbon of pharmaceuticals is understudied. This article will focus on (...) the carbon emissions of pharmaceuticals since they are consistently calculated to be among the top contributors to healthcare carbon and assess the factors that contribute to pharmaceutical carbon emissions. Specifically, overprescription, pharmaceutical waste, antibiotic resistance, routine prescriptions, non-adherence, drug dependency, lifestyle prescriptions, and drugs given due to a lack of preventive healthcare will be identified. Prescribing practices have environmental ramifications. Carbon reduction, when focused on pharmaceuticals, can lead to cleaner, more sustainable healthcare. (shrink)

Carbon offsetting can be loosely characterized as a mechanism by which an organization or individual contributes to a scheme that is projected either to remove carbon dioxide from the atmosphere or to deliver carbon dioxide emission reductions on the part of other organizations or individuals. An activity that has been offset therefore purports to make no long-term net contribution to atmospheric greenhouse gas concentrations. The ethical basis for using carbon offsetting as an approach to tackling climate (...) change is very much contested. We seek to expose some of the underlying reasons for these ethical disagreements. We show that they relate both to empirical disagreements about what the likely benefits of offsetting are and, more fundamentally, to principled disagreements about the right way to discharge duties to deliver carbon reductions.

Corporate social responsibility (CSR) is a concept aimed to ensure that corporations conduct their business in an ethical manner by taking care of their environment and human resources in addition to their economic impact. Often times, CSR refers to the steps undertaken by a corporation to measure its efforts to improve the environment and social well‐being. One of the aspects of CSR pertains to the disclosure of emission information and carbon management strategy (CMS). Carbon Management refers to analyzing (...) and focusing on those areas within the corporation where cost reductions can be made via energy reductions, waste management, and reduced resource consumption. In this article, we examine the role of an effective CMS on the emission disclosure behavior of firms. We utilize the carbon disclosure project surveys to find that firms adopting an effective CMS are more likely to disclose the information about both direct and indirect emissions. (shrink)

We examine the impact of a unilateral carbon tax in developed countries, focusing on the expected size of carbon leakage and the effects on leakage of border tax adjustments. We start by analyzing the problem using a simple two-country, three-good general equilibrium model to develop intuitions. We then simulate the expected size of the effects using a new, open-source, computable general equilibrium model. We analyze the extent of emissions reductions from a carbon tax in countries that made (...) commitments under the Kyoto Protocol, the expected carbon leakage, and the effects of border tax adjustments on carbon leakage, all relative to our baseline projections for emissions. We also perform extensive sensitivity tests on the parameters of the CGE model. Finally, we consider the effects of imperfect border tax adjustments on leakage, such as global or regional schedules of border taxes. (shrink)

In this article, we explore the world's response to the increasing impact of carbon emissions on the sobering threat posed by global warming: the carbon offset market. Though the market is a relatively new one, numerous offset providers have quickly emerged under both regulated and voluntary regimes. Owing to the lack of technical literacy of some stakeholders who participate in the market, no common quality or certification structure has yet emerged for providers. To the contrary, the media warns (...) that a relative "cowboy" atmosphere prevails in the current environment, and that there are "widespread instances of people and organizations buying worthless credits that do not yield any reductions in carbon emissions" (Harvey and Fidler, Financial Times, 2007). At this point in the evolution of the market, only a handful of offset provider-rating schemes exist; and, even these systems leave consumers with few answers when they seek to find a means by which to ensure that the said systems are having their intended impact. The purpose of this article is, first, to provide a grounded understanding of the nature of the offset market, a tendency toward carbon neutrality as a possible point of equilibrium, and the ethical tensions that surround it from the perspective of the consuming public. Second, we outline the standards environment for offset providers to illustrate most effectively the need for a single set of criteria among providers that is readily understandable by the common consumer stakeholder. We then explore the differences among the providers and articulate the specific criteria upon which providers may be evaluated by this particular stakeholder constituency, by bringing together best practices based on currently available analyses. Finally, we share the results of preliminary data collection in connection with 117 offset providers and highlight early findings. These findings allow us comparing providers effectively and efficiently on a common scale that services both providers, who thereby have greater guidance for self-assessment purposes, as well as consumer stakeholders, who then have the ability to make useful and more informed choices about carbon emission reduction in the future.

At first glance, it may seem that climate policy based on estimates of the social cost of carbon (SCC) presupposes a set of controversial assumptions, especially about what detailed knowledge regulators have about the impacts of climate change, and what the proper role of government and policy is in responding to those impacts. However, I explain why the SCC-based approach need not actually have these problematic presuppositions as well as why SCC estimates may provide the best guide to climate (...) policy when implemented in a way that incorporates a healthy dose of humility. The SCC-based approach can be used in a way that is ecumenical between the wide range of reasonable but incompatible views about the proper goals of government and policy, ranging from views that aim only at market-efficiency, to utilitarian views, to rights-based and other deontological views, to libertarian views, to virtue ethics views, and others. Beyond this, I suggest that the SCC-based approach can help us find an overlapping consensus on a particular climate policy given the range of reasonable but incompatible normative views endorsed in diverse societies. Finally, I consider a number of specific objections to the SCC-based approach that are especially prominent in contemporary discourse and policy debates. I suggest that even if we agree that all of these objections to existing SCC-based analyses have an important kernel of truth, nonetheless the correct response to climate change still involves substantial emissions reductions to be achieved via policy, and the best methods for deciding the magnitude of those reductions still depend essentially on the SCC-based approach.

Under the requirements of the national carbon reduction target, the recycling and remanufacturing of scrap iron and steel are taken by major iron and steel enterprises as requirements for implementing industrial carbon emission reduction and are incorporated into their production strategies. The scheduling optimization of scrap iron and steel remanufacturing processes plays an important role in the energy saving and emission reduction of iron and steel enterprises. In this paper, a remanufacturing production decision model for (...) scrap iron and steel considering both the product delivery time and carbon emissions was established, and a discrete krill swarm algorithm was designed to solve the multiobjective production decision model. The effectiveness of the model and the algorithm was verified by an example, demonstrating a good decision-making reference for the implementation of energy conservation and emission reduction in iron and steel enterprises.

This paper examines the role that attention to emotions around climate change can play for third sector climate change engagement initiatives, an area to which the literature on such initiatives has paid little attention. It focuses on Carbon Conversations, a programme that explicitly acknowledges the role of difficult emotions and underlying values in people's engagement with climate change. While there are limitations to this approach, results show that it can help certain audiences engage more deeply with issues around climate (...) change and carbon reduction. Important lessons can be drawn for other initiatives that aim to engage the public on climate change. (shrink)

Addressing climate change is among the most challenging ethical issues facing contemporary business and society. Unsustainable business activities are causing significant distributional and procedural injustices in areas such as public health and vulnerability to extreme weather events, primarily because of a distinction between primary emitters and those already experiencing the impacts of climate change. Business, as a significant contributor to climate change and beneficiary of externalizing environmental costs, has an obligation to address its environmental impacts. In this paper, we explore (...) the role of firms’ climate change targets in shaping their emissions trends in the context of a large multi-country sample of companies. We contrast two intentions for setting emissions reductions targets: symbolic attempts to manage external stakeholder perceptions via “greenwashing” and substantive commitments to reducing environmental impacts. We argue that the attributes of firms’ climate change targets are diagnostic of firms’ underlying intentions. Consistent with our hypotheses, while we find no overall effect of setting climate change targets on emissions, we show that targets characterized by a commitment to more ambitious emissions reductions, a longer target time frame, and absolute reductions in emissions are associated with significant reductions in firms’ emissions. Our evidence suggests the need for vigilance among policy-makers and environmental campaigners regarding the underlying intentions that accompany environmental management practices and shows that these can to some extent be diagnosed analytically.

Communication campaigns often highlight environmental progress to encourage further pro-environmental behaviour. Consequently, the drop in carbon emissions caused by the COVID-19 restrictions has been framed as a positive environmental outcome of the pandemic. We conducted an experimental study with a US-representative sample (N = 500) to show that raising awareness of emissions reduction has the contrary effect: an increase in moral self-concept facilitated a negative spillover, namely, it reduced climate-friendly behavioural intentions. Normative influence was able to prevent this (...) negative spillover because activating environmental norms inhibited compensatory feelings. Besides, awareness of recent emissions reduction was less likely to increase the moral self-concept of participants with a strong environmental self-identity. Our findings demonstrate that environmental progress increases moral self-concept which, in turn, could cause a negative spillover (i.e., reduce climate-friendly low-carbon behaviour and increase climate-harmful high-carbon behaviour). Normative influences and environmental self-identity can inhibit this negative spillover. (shrink)

Compared with traditional technological innovation modes, green technology innovation is more targeted for low carbon development and critical support for countries worldwide to combat climate change. The impact of green technology innovation on carbon emissions is considered in terms of fixed effect and mediating effect models through industrial structure upgrading. For this purpose, the sample dataset of 30 provincial administrative areas in China from 2008 to 2020 is employed. The results demonstrate that green technology innovation exerts significantly inhibitory (...) effects on carbon emissions, whose conclusion still holds after removing municipalities and replacing the dependent variable. Industrial structure upgrading is vital for green technology innovation to diminish carbon emissions. There is significant regional heterogeneity in the effects of green technology innovation on carbon emissions, i.e., the direct and indirect impact of green technology innovation on carbon emission reduction is significant in the eastern-central area, but its effect is insignificant in the western region. Therefore, it is essential to realize carbon emission reduction by further bolstering green technology innovation and accelerating industrial structure upgrading to fulfill the synergy of technology and structure.

In October 2010, the German conservative ruling coalition and Free Democratic Party ) passed a law permitting the extension of contracts for Germany’s seventeen nuclear power plants. This policy amended a law passed in 2001 by a Social Democratic Party and Green Party majority to phase out nuclear energy by the early 2020s. The explosions in the nuclear reactors at the Fukushima Daiichi nuclear power facility, however, resulted in a decision to speed up the phaseout of nuclear energy. The nuclear (...) meltdowns in Japan sent hundreds of thousands of protesters onto the streets. Angry voters made their disillusionment with the nuclear politics of the conservative government coalition clear in local elections. The federal government responded by setting up an Ethics Commission for a Safe Energy Supply, which recommended an end to nuclear energy and a shift to a renewable energy-based economy. Within months of the Fukushima disaster, the government had permanently shut down eight of the country’s oldest nuclear power plants and issued a schedule for the phased shutdown of the remaining nine plants by 2022. In addition, the government reaffirmed its climate change plans, which call for a reduction in greenhouse gas emissions by around forty percent of 1990 levels by 2020 and eighty percent by 2050. Thus, out of a crisis, the German government is forging an opportunity to become a global leader in the promotion of new renewable energies, energy efficiency, and greenhouse gas emission reductions. In Japan, the nuclear crisis has also weakened support for nuclear energy, but with a strong industrial coalition calling for its continued use, both for energy stability and in response to climate change, a complete nuclear phaseout is less certain, at least in the short term.

“Carbon neutrality, carbon peaking” is China’s national commitment to the whole world about its plans to manage global climate change. China faces many severe challenges in fulfilling its commitments to reduce emissions. China’s digital economy is currently booming, and whether it can provide opportunities for reducing regional carbon emissions is worth exploring. This study constructed a comprehensive system to evaluate the development of its digital economy based on China’s regional data and empirically tested the direct, indirect, and (...) spatial effects of the comprehensive development of digital economy on regional carbon emissions. In addition, it examined the special stage characteristics using a Hansen threshold model. This study found the following: first, the digital economy significantly suppresses carbon emissions in general, notably with a spatial spillover effect to neighboring provinces. Secondly, an analysis of the mechanism shows that the comprehensive development of a digital economy can restrain regional carbon emissions through industrial progress and the optimization of energy consumption. Third, there are double thresholds, special driving trends and an “inverted N-type” relationship with development. Fourth, a spatial heterogeneity analysis revealed that significant “local” and “neighboring” impacts on the reduction of carbon emissions only exist in the central and eastern areas. This study has a reference value for releasing the dividend of digital economy development and reducing carbon emissions. (shrink)

Due to excessive greenhouse gas emissions, carbon emission-reducing measures are urgently needed. Important emission-reduction measures mainly include carbon trading and low-carbon cost subsidies. Comprehensive consideration of these two policies is a research hotspot in the field of low-carbon technology investment. Based on this background, this paper considers the impact of consumer low-carbon preferences on market demand and the impact of uncertainty in carbon emission-reduction behaviour. We construct a stochastic differential game model with (...) upstream and downstream enterprises based on cost-sharing coordination under a cost subsidy. From a dynamic perspective, this paper researches the optimal equilibrium strategy and evolution characteristics of the joint emission-reduction mechanism in a supply chain. This paper discusses the sensitivity of the parameters and uses numerical simulation to verify the impact of each parameter on the emission-reduction decision-making activities of stakeholders after introducing the cost subsidy. The results show that a cost subsidy policy can promote carbon emission-reduction investment and supply chain profit. Thus, it is important to strengthen technical cooperation and exchange among enterprises. (shrink)

In response to Morningstar’s release of carbon risk (CR) scores in May 2018, (environmentally) sustainable mutual funds in the U.S. showed a greater reduction in their portfolio CR relative to conventional funds. The observed causal impact of this third-party disclosure is consistent with the funds’ primary investment objectives. Differences in fund names, potentially driven by marketing considerations, appear irrelevant to the behavior of sustainable funds. Conventional funds that are signatories to the UN’s Principles for Responsible Investment (PRI) or (...) those with secondary sustainability mandates behave more like other conventional funds rather than sustainable funds. These funds appear relatively insensitive to disclosures as their sustainability considerations are superseded by other primary investment criteria. Fiduciary and legal bonding influences fund managers’ response to sustainability disclosures. Sustainable funds lower their CR score by reducing exposure to fossil fuels, not by increasing exposure to renewables. (shrink)

This study provides comprehensive evidence on the link between boardroom diversity and reduction of carbon emissions. Analyzing data from a sample of 344 UK-listed non-financial and unregulated firms over the period from 2005 to 2021, our findings indicate that task-oriented (i.e., tenure) and structural (i.e., insider/outsider) board diversity are important for reducing corporate carbon emissions while relational diversity does not appear to be useful. Furthermore, the study explores the role of external carbon governance, such as the (...) Paris Agreement, on firms with weaker internal governance structures. The findings reveal that external governance plays a critical role in curbing emissions when internal governance is not effective. Overall, our research offers valuable insights for management and regulatory bodies on the interplay between various governance mechanisms internal and external to a firm. This knowledge could guide them in determining the right mix and degree of diversity in the boardroom to achieve environmental goals. (shrink)

In addition to carbon dioxide, it is becoming increasingly clear that there are numerous other potent agents of anthropogenic forcing (e.g. methane, ozone, black carbon) at work in the climate system today. The typical ethical framing of climate change has not yet accommodated this complexity. In addition, geoengineering has often been presented as a Plan B that would simply counter unintentional (and positive) anthropogenic forcing with intentional (and negative) anthropogenic forcing. This paper attempts to better address the complexity (...) by outlining an ethical framework for reducing all anthropogenic forcing, a position it labels the 'climate imperative.' The paper considers geoengineering alongside various other anthropogenic forcing activities and discusses what the climate imperative would say about each of them. On this analysis, GHG and black carbon reductions remain a priority. At the same time, the framing reveals a significant ethical difference between geoengineering through solar radiation management and through carbon dioxide removal. (shrink)

Today, cities account for the majority of global energy consumption and CO2 emissions. The interaction between cities is critical for regional low-carbon development. At this time, China has turned to the full opening of the carbon trading market as an important policy tool for achieving its ambitious emission reduction goals. This paper attempts to explore the spatial relationships among cities from the perspective of carbon trading. A “multiscenarios across different spatial scales” analysis framework applied to the (...) allocation and trading of CO2 emission quotas among cities in China is proposed. Based on this framework, the carbon trading networks of 182 cities in China are specifically simulated under four different scenarios, with a comparative analysis of the networks’ complexity made from different perspectives. The results of the study are as follows: firstly, significant spatial network correlations exist between the cities’ carbon trading under each scenario. Secondly, on a national scale, there are more inner connections in carbon trading networks, with stronger correlations and robustness, while the degree of connection of intercity carbon trading is higher overall on a regional scale. Thirdly, on a national scale, no obvious core nodes exist in the network, while core nodes do exist in the overall network and in each region under the regional scale. Fourthly, cities in the central region have the highest core position overall. Finally, based on the research results, practical guidance in using the framework for achieving carbon reduction, promoting economic growth, and balancing regional development, as well as the important inspiration for policy formulation, is further discussed.

Why, after fifty years of fossil fuelled “brown growth” and steadfast refusal to join international agreements on carbon reduction did South Korea prioritize “green growth” as an overarching national initiative in 2008? Our principal aim is to explain Korea’s ambitious pursuit of GG since that time. We argue that Korean-style environmentalism is best understood as an extension of the long-held philosophy of developmentalism amongst the policy-making elite. We first examine the origins and specify the central tenets of this (...) new philosophy that we term developmental environmentalism. We then discuss the motivations that led the policymakers to embrace developmental environmentalism, and the means by which GG was translated into swift and sustained policy action. While the empirical focus of this article is Korea, we conclude by tentatively proposing an analytical framework that might explain why some countries are more likely than others to initiate a sustained shift towards GG.

As the negative environmental impacts of transportation systems become more severe, governments and environmental groups are seeking more sustainable transportation options, such as replacing fuel-powered vehicles with electric vehicles and expanding public transportation systems to reduce the number of people driving on their own, in order to reduce the environmental impacts of transportation systems. At present, the rapid expansion of public transportation systems is not an easy task and requires a long period of time to plan for expansion and construction, (...) so people are increasingly looking to find means of transportation that meet sustainable conditions as solutions. In this context, electric bicycles are one of the solutions that people can choose, with benefits such as energy saving, carbon reduction, effective air pollution reduction, and simple and labor-saving riding. However, in Taiwan, despite the many benefits of electric bicycles, their popularity is not high. Therefore, this study focuses on the factors that affect the purchase of electric bicycles in Taiwan. The Influential Network Relation Map generated by the Z-based Decision-making Trial and Evaluation Laboratory technique is used to describe the influence relationships among the factors and to establish the key evaluation criteria of electric bicycle purchase intention. The results indicate that vehicle price, safety, motor performance, battery life, and battery durability are the most important factors in purchasing electric bicycles. Furthermore, the power of motor is considered as the factor that most significantly affects other criteria, while safety and price are most likely to be affected by other criteria. This study has contributed to academia and industry, for the dependency weights of these factors are set to provide a scientific and systematic way to show how consumers think in the decision-making process and to provide more reliable information and management implications for the electric bicycle industry.

This study examines the impact of non-executive employee stock ownership plans (ESOP) on corporate environmental engagement. We show that granting ESOPs to non-executive employees promotes greater corporate ecological engagement from the perspectives of environmental protection expenditures, environmental information disclosure quality, and environmental, social, and governance (ESG) ratings. ESOPs unite members in a common interest, empowering them to put pressure on management to reduce carbon emissions, which benefits their physical wellbeing and increases their residual interest in long-term corporate wealth. Further, (...) our analysis reveals that companies investing in environmental protection forgo short-term profit as a consequence of high initial costs, while increasing long-term firm value. These positive effects are attributable to ESOP schemes with higher employee subscription rates, those granted to a larger number of non-executive employees, and those with longer validity periods of ownership, whose incentive effect is sufficiently powerful to offset the free-rider problem. In addition, the impact of ESOPs is more pronounced in companies with greater media exposure, those confronting intense labor market competition, and those in heavily polluting industries. Fundamentally, our study provides novel evidence of the incentive effect of ESOPs on corporate environmental engagement and of stakeholder dynamics driving the implementation of carbon reduction strategies.

The carbon emissions of global healthcare activities make up 4%–5% of total world emissions, with the majority coming from industrialised countries. The solution to healthcare carbon reduction in these countries, ostensibly, would be preventive healthcare, which is less resource intensive than corrective healthcare in itself and, as a double benefit, reduces carbon by preventing diseases which may require higher healthcare carbon to treat. This leads to a paradox: preventive healthcare is designed to give humans longer, (...) healthier lives. But, by extending life spans, the carbon emissions of a person increase both over a lifetime and in the medical industry overall. At the same time, the need for higher carbon end-of-life care does not disappear, particularly in resource intensive countries. This article will first identify sources of healthcare carbon, focusing on the industrialised world, and explain various efforts towards healthcare carbon reduction, which include preventive healthcare. Second, it will develop the ‘paradox of prevention’—that preventive healthcare may save healthcare carbon by proximally reducing the need for medical treatments, but also, paradoxically, result in more healthcare carbon both in an individual’s life and in the medical industry. The third section will offer ethical principles for approaching the paradox of prevention. The conclusion will emphasise the need for institutional approaches to healthcare carbon reduction in the industrialised world, which will relieve some of the tensions of healthcare industry decarbonisation and individual healthcare carbon use.

Personal carbon footprints have become a subject of major concern among those who worry about global climate change. Conventional wisdom holds that individuals have a duty to reduce their impacts on the climate system by restricting their carbon footprints. However, I defend a new argument for thinking that this conventional wisdom is mistaken. Individuals, I argue, have a duty to take actions to combat the world’s problems. But since climate change is only one of a nearly endless list (...) of such problems, individuals’ obligations to take action as activists do not specifically require reductions in personal carbon footprints. Moreover, this is true even in spite of the fact that we are personally implicated in causing climate change. This paper also argues that many of those who decide to combat climate change by reducing their carbon footprints are likely doing more than they can justify in this regard. Although most people are not doing enough to combat world problems, a proper devotion to activism would seek a balance with other life demands that many climate activists currently eschew. (shrink)

In recent years, the target of reaching “net zero” emissions by 2050 has come to the forefront of global climate politics. Net zero would see carbon emissions matched by carbon removals and should allow the planet to avoid dangerous climate change. But the recent prominence of this goal should not distract from the fact that there are many possible versions of net zero. Each of them will have different climate justice implications, and some of them could have very (...) negative consequences for the world's poor. This article demonstrates the many ambiguities of net zero, and argues in favor of a net zero strategy in which those who can reasonably bear the burden adopt early and aggressive mitigation policies. We also argue for a net zero strategy in which countries place the lion's share of their faith in known emissions reduction approaches, rather than being heavily reliant on as-yet-unproven “negative emissions techniques.” Our overarching goal is to put net zero in its place, by providing a clear-sighted view of what net zero will achieve, and where the “net” in net zero needs to be tightened further if the world is to achieve climate justice.

Future population growth is uncertain and matters for climate policy: higher growth entails more emissions and means more people will be vulnerable to climate-related impacts. We show that how future population is valued importantly determines mitigation decisions. Using the Dynamic Integrated Climate-Economy model, we explore two approaches to valuing population: a discounted version of total utilitarianism (TU), which considers total wellbeing and is standard in social cost of carbon dioxide (SCC) models, and of average utilitarianism (AU), which ignores population (...) size and sums only each time period’s discounted average wellbeing. Under both approaches, as population increases the SCC increases, but optimal peak temperature decreases. The effect is larger under TU, because it responds to the fact that a larger population means climate change hurts more people: for example, in 2025, assuming the United Nations (UN)-high rather than UN-low population scenario entails an increase in the SCC of 85% under TU vs. 5% under AU. The difference in the SCC between the two population scenarios under TU is comparable to commonly debated decisions regarding time discounting. Additionally, we estimate the avoided mitigation costs implied by plausible reductions in population growth, finding that large near-term savings ($billions annually) occur under TU; savings under AU emerge in the more distant future. These savings are larger than spending shortfalls for human development policies that may lower fertility. Finally, we show that whether lowering population growth entails overall improvements in wellbeing—rather than merely cost savings—again depends on the ethical approach to valuing population.

Development of carbon neutral energy sources is essential if the US is to reduce the release of greenhouse gases and the associated potential for global climate change. In the US a few giant corporations dominate the energy sector. Furthermore, there has been virtually no federal leadership on energy issues, and the awareness of the issues by the general public, let alone their understanding of them, is low. In Europe, the energy sector is also dominated by a few players, but (...) the higher awareness of the public, the long lasting efforts of NGOs and other stakeholders, in addition to the mandatory regulations (both at a national and an European level) has created a different “energy landscape”. Even in Europe, the current and pending reductions in CO2 emissions are still far short of what is required and the level of understanding of the issues by the public is still relatively low on both continents. In this paper, we identify and discuss the main politicalchallenges and drivers in the energy and climate debate, and we point out that while the energy sector has no interest to tackle greenhouse gas emissions without significantly greater public pressure, Corporate Social Responsibility (CSR) in this sector could nonetheless play a key role in changing US energy policy, but at the same time is very unlikely to be sufficient by itself.

We study 944 shareholder proposals submitted to 343 U.S. firms on climate change issues during 2009–2022. We use logistic and two-stage regression to estimate the propensity for a firm to be targeted or subjected to a vote at the annual general meeting and, for voted proposals, the determinants of that vote. We also examine whether climate-related proposals affect investor returns and how they relate to firms’ future environmental performance and greenhouse gas emissions. Compared to a matched sample, we first find (...) that activists target larger, more carbon-intensive, and less R&D-active firms. Second, voting likelihood is higher for firms with repeated and operations-related proposals and lower pre-proposal environmental ratings. By contrast, disclosure-related proposals are likelier to be negotiated and withdrawn. Third, repeated and operations-related proposals receive higher votes in favor, whereas votes on carbon-intensive firms do not. Fourth, building on the theory that investors act as if they distinguish among the different shareholder proposals based on the expected cost to the firm, we find evidence to support this idea. We find that investors respond negatively to ex-ante costlier proposals, such as those that relate to emissions reduction and target carbon-intensive firms. Fifth, targets’ future environmental performance rating is almost twenty percent higher after a proposal than before compared to the matched sample, whereas emissions do not budge appreciably.

Burning fossil fuel in the North American continent contributes more to the CO2 global warming problem than in any other continent. The resulting climate changes are expected to alter food production. The overall changes in temperature, moisture, carbon dioxide, insect pests, plant pathogens, and weeds associated with global warming are projected to reduce food production in North America. However, in Africa, the projected slight rise in rainfall is encouraging, especially since Africa already suffers from severe shortages of rainfall. For (...) all regions, a reduction in fossil fuel burning is vital. Adoption of sound ecological resource management, especially soil and water conservation and the prevention of deforestation, is important. Together, these steps will benefit agriculture, the environment, farmers, and society as a whole. (shrink)

In cases in which there is the possibility of massive human losses, the threshold likelihood of their occurrence, and the non-excessive costs of their prevention, we ought to act now. This is all the more definitely the case because it may well be that this is the time-of-last-opportunity to head off one or more potential disasters, all of which may still be preventable by sufficiently rapid reductions in carbon emissions from the combustion of fossil fuel. It is unfair that (...) the present generation should incur as heavy a burden as it does of seizing the last opportunity for prevention of disasters like large sea-level rises, but the unfairness is not sufficient to make the burden unreasonable to bear, especially since it is not in fact as heavy as often believed.

In this paper, we argue that rationing has been neglected as a policy option for mitigating climate change. There is a broad scientific consensus that avoiding the most severe impacts of climate change requires a rapid reduction in global emissions. We argue that rationing could help states reduce emissions rapidly and fairly. Our arguments in this paper draw on economic analysis and historical research into rationing in the UK during (and after) the two world wars, highlighting success stories and (...) correcting misconceptions. However, although the empirical details play an important role, the paper is primarily based on philosophical and ethical argument and policy analysis, particularly highlighting the normative assumptions behind policy choices.We build on Hugh Upton’s work in healthcare ethics, rejecting a broader conception of rationing which conceals significant distinctions between policy options, obscuring the specific advantages of an egalitarian conception of rationing. While some argue for the modernisation of rationing, introducing tradable allowances, we argue that the rejection of markets, and a commitment to fair shares, is a key part of the value of rationing, and precisely what made rationing attractive to the public in the 1940s.

Purpose – Information and communications technology offers a peculiar twenty-first century conundrum, as it offers both a cause and solution to rising carbon emissions. The growth in the digital economy is fueling increased energy consumption while affording new opportunities for reducing the environmental impacts of our daily lives. This paper responds and builds on Patrignani and Whitehouse’s overview of Slow Tech by providing examples of how ICT can be used to reduce energy. Encouraging examples are provided from the field (...) of energy and buildings and implications for wider society are raised. Design/methodology/approach – This paper builds on the previous overview “The Clean Side of Slow Tech”, based on a comprehensive knowledge of literature of the latest developments in the field of digital economy, energy and sustainability. Findings – This paper provides clear and encouraging signs of how ICT can be used to contribute to sustainability through controlling systems more efficiently, facilitating behavioural changes and reducing energy consumption. Future challenges and recommendations for future research are presented. Originality/value – This conceptual paper presents the latest research into the use of ICT in energy reduction and offers cautious, but encouraging signs that while the environmental impact of ICT must not be overlooked, there are benefits to be had from the digital economy.

China declared a long-term commitment at the United Nations General Assembly in 2020 to reduce CO2 emissions. This announcement has been described by Reuters as “the most important climate change commitment in years.” The allocation of China’s provincial CO2 emission quotas is crucial for building a unified national carbon market, which is an important policy tool necessary to achieve carbon emissions reduction. In the present research, we used historical quota data of China’s carbon emission trading policy (...) pilot areas from 2014 to 2017 to identify alternative features of corporate CO2 emissions and build a backpropagation neural network model to train the benchmark model. Later, we used the model to calculate the quotas for other regions, provided they implement the carbon emission trading policy. Finally, we added up the quotas to obtain the total national quota. Additionally, considering the perspective of carbon emission terminal, a new characteristic system of quota allocation was proposed in order to retrain BP including the following three aspects: enterprise production, household consumption, and regional environment. The results of the benchmark model and the new models were compared. This feature system not only builds a reasonable quota-related indicator framework but also perfectly matches China’s existing “bottom-up” total control quota approach. Compared with the previous literature, the present report proposes a quota allocation feature system closer to China’s policy and trains BP to obtain reasonable feature weights. The model is very important for the establishment of a unified national carbon emission trading market and the determination of regional quotas in China. (shrink)

This paper explores why it is so hard for us to do what we morally ought to do to mitigate anthropogenic climate change by reducing our carbon dioxide, CO2, emissions. It distinguishes between two sources of this difficulty: factors which make us underrate the harm that we individually cause when we perform our everyday CO2 emitting acts and, thus, the wrongness of these acts, and factors which make it difficult for us to cooperate to the extent necessary to mitigate (...) effectively harmful climate change by reducing our everyday CO2 emitting acts. Under are listed such factors as the temporal remoteness of climate harm, the fact that the causal connections between our acts and this harm are elusive, that countless agents together cause harm which is diffused widely over countless, anonymous victims, by acts routinely done. As regards, a comparison with the problems of cooperation in the well-known tragedy of the commons is natural, but it is here argued that the problem of reducing our CO2 emissions is disanalogous in several respects which make it harder: the world’s nations differ enormously in respect of level of welfare, their record of past emissions, and the degree of exposure to climate harm; additionally, it is harder to survey compliance and apply sanctions to those who defect from agreements, in particular as future generations who have not consented to these agreements are involved. Together these factors make up a good case for saying that the problem of ameliorating anthropogenic climate change by reduction of our CO2 emissions is the hardest moral problem humanity is facing.

This paper refutes the mechanistic interpretation of cellular dynamics and contends that the life-giving principle is sustained growth a biological system and is uninterrupted growth balanced in a dynamic state by synthesis and dissolution. The process began by an oxidation/reduction reaction on the surface of pyrite energized photovoltaically by sunlight. Hydrogen sulfide was oxidized, carbon dioxide was reduced, and phosphate on the surface of the pyrite was a reactant. The first organic compounds were sulfides and phosphoglycerates. These organophosphates (...) were at the center of the energy cycle of all life where the dehydration of a relatively unreactive “low-energy” two-phosphoglycerate transforms it into the “high-energy” phosphoenolpyruvate. Life began as a growth process and continues to grow ceaselessly out of necessity. It cannot discontinue the life-giving energy flow without irreparable loss of the process. All forms of life past and present were and are stabilized systems in which the growth process is contained in metabolic turnover. (shrink)

Scale (gross domestic product), composition (goods and services), and technology (impacts per unit of goods and services) in combination are the proximate determinants in an economy of the resources used, wastes generated, and land transformed. In this article, we examine relationships among these determinants to understand better the contribution that changes in each have made in the past, and might in the future, to reduce the burden placed on the environment by the economy. Using the IPAT equation we assess quantitatively (...) historical changes in scale, composition, and technology in Canada and their respective contributions to changes in environmental impact. The Kaya equation provides a similar framework for a more in-depth consideration of the changes in scale, composition, and technology required to achieve a substantial reduction in global emissions of carbon dioxide. We conclude that it is essential to address scale as part of the solution. (shrink)

A global target of stabilizing greenhouse-gas concentrations at between 450 and 550 parts per million carbon-dioxide equivalent has proven robust to recent developments in the science and economics of climate change. Retrospective analysis of the Stern Review suggests that the risks were underestimated, indicating a stabilization target closer to 450 ppm CO2e. Climate policy at the international level is now moving rapidly towards agreeing an emissions pathway, and distributing responsibilities between countries. A feasible framework can be constructed in which (...) each country takes on its own responsibilities and targets, based on a shared understanding of the risks and the need for action and collaboration on climate change. The global deal should contain six key features: a pathway to achieve the world target of 50 per cent reductions by 2050, where rich countries contribute at least 75 per cent of the reductions; global emissions trading to reduce costs; reform of the clean development mechanism to scale up emission reductions on a sectoral or benchmark level; scaling up of R&D funding for low-carbon energy; an agreement on deforestation; and adaptation finance.

In the five-year period 2005-2009, Brazil dramatically reduced carbon emissions by about twenty-five percent and at the same time maintained a stable economic growth rate of 3.5% annually. This combination of economic growth and emissions reduction is unique in the world. It was driven by a dramatic reduction in deforestation in the Amazonian forest and the Cerrado Savannah. This shift empowered the sustainability social forces in Brazil to the point that in December 2009 Congress passed a very (...) progressive law internalizing carbon constraints and promoting the transition to a low-carbon economy. The Article first analyzes the Brazilian position in the global carbon cycle and public policies since 2005, including the progressive shift in 2009 and the contradictory dynamic in 2010-2012. It then analyzes the potential for a transition to a low-carbon economy in Brazil and the impact on global climate governance. (shrink)

Most studies on climate change response have examined reductions in greenhouse gas (GHG) emissions. Yet these studies do not take into account ecosystem services constraints and biophysical disruptions wrought by climate change that may require broader types of response. By studying a firm in the wine industry and using a research approach not constrained by structured methodologies or biased toward GHG emissions, the findings suggest that both “inside out” and “outside in” actions are taken in response to climate change. While (...) attempts are made by the firm to curtail and reverse climate change through management of carbon emissions, evidence suggests a clear pattern of actions designed to adjust to the adverse consequences of climate change as well. The results both confirm and extend previous findings and suggest that the level and breadth of response to climate change is shaped by situated attention, structural controls, and industry type.

As global warming is gradually pushing the Earth to the climate tipping point, the reduction of CO2 concentration in the atmosphere has become more urgent than ever. Many high-tech methods, such as Carbon Capture and Storage (CCS) technologies, have been proposed as crucial tools in the fight against climate change. However, this paper argues that the expensiveness and uncertainty of CCS technologies make them not feasibly deployed. Persistent investment in these technologies also reinforces the outdated eco-deficit mindset that (...) prioritizes monetary over environmental values. In contrast, the recent flood in the Sahara desert turned barren areas green, reminding us that nature, when given the opportunity, can have an astonishing capacity to heal itself. Investing billions of dollars in deploying costly and uncertain high-tech solutions while limiting funds for local communities to take care of reliable natural carbon sinks risks depleting humanity's resources to tackle climate change, especially when the tipping points are closed.

This paper considers the environmental justice issues presented by the proposed open-pit lithium mine in Thacker Pass, Nevada (Peehee mm’huh). Unlike the environmental destruction wrought from fossil fuel extraction, lithium is used to create lithium-ion batteries for storing and using electricity from “green energy” sources. Can the potential reduction in carbon emissions resulting from the lithium mined morally and politically justify the destruction of the Pass’s sagebrush sea – a critical wildlife habitat and sacred land to the People (...) of Red Mountain? Justice issues of this kind (e.g., clashes between the “renewable energy” industry and indigenous rights) are likely to become more prevalent as the industrial economy transitions from fossil fuels to vastly more spatially extensive forms of energy production (e.g., wind and solar farms, hydroelectric dams, and biofuels). I consider the case through the concept of ecocide and explore how liberal political respect for eco-relational pluralism offers grounds on which ecocide ought to be prohibited in a fair and just society. The goal of this paper is to ensure that states, in the pursuit of environmental justice, proceed in a manner aligned with their commitment to liberalism, by refraining from prioritizing economic growth and development at the expense of other reasonable conceptions of the good.

The relevance of the research is the intensity of noise emitted by lorries depends on the regime of the vehicle movement. One of the main negative factors caused by road vehicles is air pollution with exhaust gases. The article presents results for noise caused by lorries and gas usage while the vehicle is accelerating. The subject of the study is 4 lorries, and they also feature fuel recording systems which are less than 5 years old. Research methodology. The level of (...) noise emitted by heavyweight transport vehicles is measured according to Lithuanian standard LST ISO 1996-2:2008 requirements. During the tests the noise levels of L A,eq, L C,eq, L C,peak were measured. The tests were done 5 times each and the results are presented as arithmetical averages. Fuel consumption is registered in vehicle data registration system. The researched vehicles have to comply with environmental safety normative requirements; that the vehicle carbon monoxide, particulate matter, nitrogen oxides, unburned fuel and other hazardous substances contained in the combustion gases must not exceed the prescribed limits. The results of the experimental studies show that EURO6 lorries noise level is the lowest compared to the EURO4 and EURO5. After carrying out the analysis of the caused noise and gas usage, it was found that noise pollution and gas usage are higher without speed control system. The noise caused by lorries can be described in square polynomial which defines the noise inclination change while vehicle is accelerating. Scientific novelty of the research a complex research on noise and fuel consumption of lorries by using and not using speed control system. Research idea and problem is to achieve sustainable transport development objectives, in particular the reduction of greenhouse gas emissions under the Kyoto Protocol. It is very important to find ways to forecast and reduce transport noise pollution, while also reducing overall pollution, as well as mitigating the impact on the global climate., Conclusion – after conducting a lorry noise and fuel consumption analysis, it was determined that not using speed control system increases the noise and fuel consumption and if the system is used both of these factors decrease drastically.
