Obligations to reduce one’s green house gas emissions appear to be difficult to justify prior to large-scale collective action because an individual’s emissions have virtually no impact on the environmental problem. However, I show that individuals’ emissions choices raise the question of whether or not they can be justified as fair use of what remains of a safe global emissions budget. This is true both before and after major mitigation efforts are in place. Nevertheless, it remains (...) difficult to establish an obligation to reduce personal emissions because it appears unlikely that governments will in fact maintain safe emissions budgets. The result, I claim, is that under current conditions we lack outcome, fairness, promotional, virtue or duty based grounds for seeing personal emissions reductions as morally obligatory. (shrink)

“Throw away anything that sounds too complicated. Only keep what is simple to grasp...If the information appears fuzzy and causes the brain to implode after two sentences, toss it away and stop listening. Doing so will make the news as orderly and simple to understand as the truth.” - In “GHG emissions,” The Kingfisher Story Collection, (Vuong 2022a).

In this article we analyse the role that artificial intelligence (AI) could play, and is playing, to combat global climate change. We identify two crucial opportunities that AI offers in this domain: it can help improve and expand current understanding of climate change and it contribute to combating the climate crisis effectively. However, the development of AI also raises two sets of problems when considering climate change: the possible exacerbation of social and ethical challenges already associated with AI, and the (...) contribution to climate change of the greenhouse gases emitted by training data and computation-intensive AI systems. We assess the carbon footprint of AI research, and the factors that influence AI’s greenhouse gas (GHG) emissions in this domain. We find that the carbon footprint of AI research may be significant and highlight the need for more evidence concerning the trade-off between the GHG emissions generated by AI research and the energy and resource efficiency gains that AI can offer. In light of our analysis, we argue that leveraging the opportunities offered by AI for global climate change whilst limiting its risks is a gambit which requires responsive, evidence-based and effective governance to become a winning strategy. We conclude by identifying the European Union as being especially well-placed to play a leading role in this policy response and provide 13 recommendations that are designed to identify and harness the opportunities of AI for combating climate change, while reducing its impact on the environment.

A book chapter (about 9,000 words, plus references) presenting an act-consequentialist approach to the ethics of climate change. It begins with an overview of act consequentialism, including a description of the view’s principle of rightness (an act is right if and only if it maximizes the good) and a conception of the good focusing on the well-being of sentient creatures and rejecting temporal discounting. Objections to act consequentialism, and replies, are also considered. Next, the chapter briefly suggests that act consequentialism (...) could reasonably be regarded as the default moral theory of climate change, in the sense that a broadly act-consequentialist framework often seems implicit in both scholarly and casual discussions of the ethics of climate change. The remainder of the chapter explores three possible responses to the threat of climate change: having fewer children to reduce the number of people emitting greenhouse gases; taxing greenhouse-gas (GHG) emissions (commonly called a “carbon tax”) to discourage GHG-emitting behavior; and reducing poverty to lessen personal, familial, and community vulnerability to the harms of climate change.

There appear to be few ways available to improve the prospects for international cooperation to address the threat of global warming within the very short timeframe for action. I argue that the most effective and plausible way to break the ongoing pattern of delay in the international climate regime is for economically powerful states to take the lead domestically and demonstrate that economic welfare is compatible with rapidly decreasing GHG emissions. However, the costs and risks of acting first can (...) be very large. This raises the question of whether it is fair to expect some states to go far ahead of others in an effort to improve the conditions for cooperation. I argue that a costly obligation to act unilaterally and to accept weak initial reciprocity can be justified and does not violate standards of fair burden sharing. Rather, the costs of creating the underlying conditions within which we can hope to achieve meaningful international cooperation are non-­‐ideal burdens for which we can appropriately assign fair shares.

Several philosophers have recently argued that policies aimed at reducing human fertility are a practical and morally justifiable way to mitigate the risk of dangerous climate change. There is a powerful objection to such “population engineering” proposals: even if drastic fertility reductions are needed to prevent dangerous climate change, implementing those reductions would wreak havoc on the global economy, which would seriously undermine international antipoverty efforts. In this article, we articulate this economic objection to population engineering and show how it (...) fails. We argue, first, that the economic objection paints an inaccurate picture of the complicated relationship between demographic change and economic growth, and second, that any untoward economic effects of fertility reduction can be mitigated with additional policies. Specifically, we argue that supplementing fertility reduction with policies that facilitate the emigration of younger people from developing nations to developed nations could allow for both global reductions in GHG emissions and continued economic stability. Further, we show that moral arguments against such unprecedented increases in immigration are unsuccessful. We conclude that population engineering is a practical and morally justifiable tool for addressing the twin evils of climate change and global poverty. (shrink)

In this paper, we aim to provide an in-depth discussion of nickel's crucial position in the manufacturing sector in the context of the United Nations' Sustainable Development Goals (SDGs), which represent growing environmental imperatives. These SDGs have gained unprecedented urgency due to looming concerns of incompletion. It should be emphasized that the information compiled herein is derived from authoritative sources and is limited in its ability to give comprehensive coverage within the scope of this article. The raised issues are of (...) broad interest in terms of environmental dynamics in the global nickel mining, extraction, and refining arenas. As a result, the content given below may not precisely comply with the local situations dictated by geographical, geological, and socio-economic characteristics. The fundamental goal of this discussion is to clarify the economic-environmental interaction and the pragmatic meanings of the term "sustainable" in the context of the nickel industry. (shrink)

Abstract: The scientific evidence is now overwhelming that human activity is causing the Earth’s atmosphere to grow hotter, which is leading to global climate change. If current rates of greenhouse gas (GHG) emissions continue, it is predicted that there will be dramatic changes, including flooding, more intense heat waves and storms, and an increase in (...) disease. Indigenous peoples and the poor will be most severely affected, as will Earth’s wild animals and plants, a quarter of which could become extinct in fifty years. We urgently need to switch to renewable (non-GHG emitting) energy sources, and try to live in a simpler, more sustainable way. In this article, a renewable energy expert, a biochemist, and a theologian have come together to describe the situation in which we find ourselves, and present ideas for a solution that incorporates Catholic social teaching.

Compelling research in international relations and international political economy on global warming suggests that one part of any meaningful effort to radically reverse current trends of increasing green house gas (GHG) emissions is shared policies among states that generate costs for such emissions in many if not most of the world’s regions. Effectively employing such policies involves gaining much more extensive global commitments and developing much stronger compliance mechanism than those currently found in the Kyoto Protocol. In other (...) words, global warming raises the prospect that we need a global form of political authority that could coordinate the actions of states in order to address this environmental threat. This in turn suggests that any serious effort to mitigate climate change will entail new limits on the sovereignty of states. In this book I focus on the normative question of whether or not we have clear moral reasons to bind ourselves together in such a supranational form of political association. I argue that one can employ familiar liberal arguments for the moral legitimacy of political order at the state level to show that we do have a duty to support such a global political project. Even if one adopts the premises employed by the most influential forms of liberal scepticism to the ideas of global political and distributive justice, such as those advanced by John Rawls and Thomas Nagel, it is clear that the threat of global warming has expanded the scope of justice. We now have a global and demanding duty of justice to create the political conditions that would allow us to collectively address our impact on the Earth’s atmosphere. (shrink)

Abstract— According to studies, buildings use around 40% of the total energy consumption in the world. Most of this consumed energy comes from fossil fuel, one of the sources of environmental pollution. The Net Zero Energy Building (NZEB) is an alternative to this alarming pollution. With its reduced energy needs and renewable energy systems, a ZEB can return as much energy as it takes from the utility on an annual basis. Thus the main objective of this study is to discuss (...) the economical and friendly environmental renewable energy system integrated to building in Egypt to be (NZEB) economical by maximizing the renewable energy fraction and minimizing the greenhouse gases (GHG) emissions. The system consists of two renewable energy sources, comprising photovoltaic system, a wind turbine are considered for the proposed building under the study. By Utilizing the well-known Hybrid Optimization of Multiple Electric Renewables software to get the optimal configuration of a hybrid renewable energy system, based on the user inputs of loads, costs, technical details, solar and wind resources availability.

In their ‘Ethical and Technical Challenges in Compensating for Harm Due to Solar Radiation Management Geoengineering’ (2014), Toby Svoboda and Peter Irvine (S&I) argue that there are significant technical and ethical challenges that stand in the way of crafting a just solar radiation management (SRM) compensation system. My aim in this article is to contribute to the project of addressing these problems. I do so by focusing on one of S&I’s important ethical challenges, their claim that the polluter pays principle (...) (PPP) is too problematic to be useful in determining responsibility for SRM compensation. Their argument for the latter claim consists in a series of allegations, mostly in the form of questions, that are thought to indicate serious difficulties standing in the way of using the PPP to craft a just compensation system. I argue that S&I fail to substantiate these allegations: the PPP is not as problematic as S&I suggest, and moreover, is a viable candidate for determining responsibility for SRM compensation. S&I raise five allegations against the PPP. I discuss each in turn. (shrink)

ABSTRACT Offsetting is a very ineffective way to do good. Offsetting your lifetime emissions may increase aggregated life expectancy by at most seven years, while giving the amount it costs to offset your lifetime emissions to a malaria charity saves in expectation the life of at least one child. Is there any moral reason to offset rather than giving to some charity that does good so much more effectively? There might be such a reason if your offsetting compensated (...) or somehow benefitted the victims of your emission, since that could mean that you would satisfy the duty not to harm others by emitting and offsetting. But that is typically not true. If your emission harms some person and your offsetting benefits some person, then these are most likely different people. Hence, I conclude, we have a stronger reason to give to effective charities than we have to offset our emissions. (shrink)

In discussions about responsibility for climate change, it is often suggested that the historical use of natural resources is in some way relevant to our current attempts to address this problem fairly. In particular, both theorists and actors in the public realm have argued that historical high-emitters of greenhouse gases (GHGs) – or the beneficiaries of those emissions – are in possession of some form of debt, deriving from their overuse of a natural resource that should have been shared (...) more equitably. These accounts of what might be termed ‘natural debt’ generally focus on one particular natural resource (global GHG sink capacity); invoke a principle of justice by which rights to consume this resource should have been allocated (most commonly, equal per capita shares); and then argue that historical violations of this principle give rise to certain rectificatory duties in the present (generally, duties on the part of those who have historically consumed an excessive amount of the world’s GHG sink capacity, or who have benefitted from such excess consumption, to offer some form of compensation to those who have not – such compensation usually taking the form of emission credits or cash). Though many seem to find it intuitively plausible that historical high-emissions have incurred some form of debt, significant challenges arise in rendering the concept of natural debt both coherent and defensible. Such problems are not, however, my focus in this piece. Instead, I here suggest that discussions about historical responsibility for climate change commonly fail to recognise certain other past injustices concerning natural resources that appear to hold contemporary relevance. In particular, I argue that it is not just the unequal consumption of global GHG sink capacity that may be of moral significance here; but also the way in which the world’s resources have more generally been governed.

In the face of the climate crisis, countries around the globe have committed to reducing greenhouse gas emissions (GHG) and achieving carbon neutrality. While the effects of such commitments remain ambiguous, some risks and obstacles could potentially hinder nations, even leading to failure in fulfilling their climate commitments. The paper presents four major challenges that can impede the global progress towards emission reduction targets as pledged: 1) energy security and global socio-economic development demands, 2) political conflicts, geopolitical instability, and (...) warfare, 3) challenges in developing and scaling emission reduction technologies, and 4) public perceptions toward climate change. Without addressing these challenges, humanity and the Earth's ecosystems will face the dangers of venturing into “uncharted waters” full of uncertainties and disorder. A potential solution to these issues is for the world to transition from an eco-deficit culture to an eco-surplus culture, where the lasting values of Earth's ecosystems are recognized as the conscience of our time.

The global Climate Change has unprecedented consequences in terms of scale and severity over human life. The accumulation of greenhouse gases and CFCs has increased environmental deterioration which is called global warming. Erratic changes in weather, brutal blizzards and floods, vicious heat wave etc. are only some of the effects of climate change. But the most dangerous effect of climate change is the melting of ice caps on the poles due to which sea levels are rising dangerously and life at (...) the poles is threatened. It is also a reality that habitation in several countries , not very much above the sea-level, for example, Maldives, Sri Lanka, Bangladesh and Indonesia, which have a threat of huge displacement of human beings and domestic animals due to global warming. The survival of millions of people in developing countries like India is more vulnerable to the negative impacts of climate change because of their limited capacity in terms of human financial and institutional resources. India is the world’s fourth largest economy and fifth largest greenhouse gas (GHG) emitter, accounting for about 5% of global emissions. India’s emissions increased 65% between 1990 and 2005 and are projected to grow another 70% by 2020. The major impacts of Climate Change on India are major shifts in temperature, effect on monsoons, rising of sea levels, change in crop cycle, etc. India has prepared the National Action Plan on Climate Change (NAPCC) in 2008 for energy efficiency and sustainable development. India is a part to the United Nations Framework Convention on Climate Change. Under the Ministry of Environment and Forests, a National Inventory Management System (NIMS) has been formed to generate a comprehensive knowledge base on scientific issues related to climate change and mitigation. This paper highlights the issue of impacts of climate change and measures adopted by the government to minimize the dangers. (shrink)

Emissions grandfathering holds that a history of emissions strengthens an agent’s claim for future emission entitlements. Though grandfathering appears to have been influential in actual emission control frameworks, it is rarely taken seriously by philosophers. This article presents an argument for thinking this an oversight. The core of the argument is that members of countries with higher historical emissions are typically burdened with higher costs when transitioning to a given lower level of emissions. According to several (...) appealing views in political philosophy (utilitarianism, egalitarianism, prioritarianism, and sufficientarianism) they are therefore entitled to greater resources, including emission entitlements, than those in similar positions but with lower emissions. This grandfathering may play an especially important role in allocating emission entitlements among rich countries. (shrink)

“Since the actions I perform as an individual only have an inconsequential effect on the threat of climate change,” a common argument goes, “it cannot be morally wrong for me to take my car to work everyday or refuse to recycle.” This argument has received a lot of scorn from philosophers over the years, but has actually been defended in some recent articles. A more systematic treatment of a central set of related issues shows how maneuvering around these issues is (...) no easy philosophical task. In the end, it appears, the argument from inconsequentialism indeed is correct in typical cases, but there are also important qualificatory considerations. (shrink)

The idea of permit trading in the United States can be traced as far back as the 1970s, but emissions trading has really only became a popular and exportable idea with the more recent demands that environmental protection acknowledge economic pressures through such ideas as sustainable development. Now the idea of emissions trading has caught on in South America, China and Europe as well. Yet in the eagerness of governments and industry to work out the technical details and (...) legal mechanics of the emissions trading tool, insufficient attention has been paid to its underlying legal and ethical assumptions. In this article, it is emphasized that emissions trading is a part of compliance with environmental law, not a market alternative to compliance. The difference between the two greatly effects and is affected by theories of rights. As part of the scheme of rights and accompanying duties, the author questions whether an implicit right to pollute has been created through emissions trading, as exemplified by the comparison of the systems in the U.S., China and Europe.

With respect to climate change, what is wanted is an account that morally condemns the production of ‘luxury’ greenhouse gas emissions (e.g., joyriding in an SUV), but not ‘subsistence’ emissions (e.g., cooking meals). Now, our individual greenhouse gas emissions either cause harm, or they do not—and those who condemn the production of luxury emissions generally stake their position on the grounds that they do cause harm. Meanwhile, those seeking to defend the moral permissibility of luxury (...) class='Hi'>emissions generally do so by arguing that our individual emissions do not cause harm. Here, I argue that, if our individual emissions do cause harm, then this entails too much. For, it entails not only that our luxury emissions are morally impermissible, but that our subsistence emissions are too. This is an undesirable result. Therefore, I propose that we embrace our other option. Namely, I propose that we accept that our individual emissions do not cause harm; or at least, that they make no perceptible difference with respect to the harms associated with climate change. The result of this admission is not as bad as you might think. For, I argue, even if we are individually causally impotent with respect to the harms of climate change, there remains a plausible route toward the moral condemnation of our individual luxury emissions—contrary to what others have argued. What is more, only by accepting our individual causal impotence can we successfully ground the permissibility of our individual subsistence emissions. (shrink)

Non-technical summary: -/- When developing and deploying negative emissions technologies (NETs), little attention has been paid to where. On the one hand, one might develop NETs where they are likely to contribute most to global mitigation targets, contributing to a global climate solution. On the other hand, one might develop NETs where they can help support development on a regional basis, justified by regional demands. I defend these arguments and suggest that they reflect the values of efficiency and responding (...) to need, respectively. To the extent that these values conflict, they introduce what I call the Need-Efficiency Trade-off Effect (‘NET Effect’). -/- Technical summary: -/- Unlike other geoengineering methods, the effectiveness of negative emissions technologies (NETs) tends to be sensitive to regional siting. This paper argues that this point raises morally and legally important implications by identifying a trade-off between ‘efficiency’ and ‘need’. First, it introduces two arguments justifying NETs: one focused on contributions to global mitigation and the other focused on contributions to regional development. Second, reflecting the two arguments, the paper discusses the moral values of efficiency and need, respectively. For instance, if the strategy is to try to use NETs to maximize expected mitigation contributions to reflect efficiency, then deployment should occur in regions with the best prospects for success (e.g. Western countries). However, if the strategy is to try to use NETs to improve the chances of simultaneous development and mitigation to respond to need, then deployment should occur in regions with limited development and expected growth of demand for NETs (e.g. Asian countries). When these values conflict, I call that a Need-Efficiency Trade-off Effect (‘NET Effect’). The paper concludes by considering the NET Effect in the context of bioenergy with carbon capture and storage as well as direct air carbon capture and storage. [Open access]. (shrink)

Climate change and other harmful large-scale processes challenge our understandings of individual responsibility. People throughout the world suffer harms—severe shortfalls in health, civic status, or standard of living relative to the vital needs of human beings—as a result of physical processes to which many people appear to contribute. Climate change, polluted air and water, and the erosion of grasslands, for example, occur because a great many people emit carbon and pollutants, build excessively, enable their flocks to overgraze, or otherwise stress (...) the environment. If a much smaller number of people engaged in these types of conduct, the harms in question would not occur, or would be substantially lessened. However, the conduct of any particular person (and, in the case of climate change, of even quite large numbers of people) could make no apparent difference to their occurrence. My carbon emissions (and quite possibly the carbon emissions of much larger groups of people dispersed throughout the world) may not make a difference to what happens to anyone. When the conduct of some agent does not make any apparent difference to the occurrence of harm, but this conduct is of a type that brings about harm because many people engage in it, we can call this agent an overdeterminer of that harm, and their conduct overdetermining conduct. In this essay we explore the moral status of overdetermining harm. (shrink)

Given that mitigating climate change is a large-scale global issue, what obligations do individuals have to lower their personal carbon emissions? I survey recent suggestions by Walter Sinnott-Armstrong and Dale Jamieson and offer models for thinking about their respective approaches. I then present a third model based on the notion of structural violence. While the three models are not mutually incompatible, each one suggests a different focus for mitigating climate change. In the end, I agree with Sinnott-Armstrong that people (...) have limited moral obligations to directly lower personal emissions, but I offer different reasons for this conclusion, namely that the structural arrangements of our lives place a limit on how much individuals can restrict their own emissions. Thus, individuals should focus their efforts on changing the systems instead (e.g., the design of cities, laws and regulation, etc.), which will lead to lower emissions on a larger scale. (shrink)

Some philosophers are skeptical that individuals are morally blameworthy for their own greenhouse gas emissions. Although an individual’s emissions may contribute to climate change that is on the whole very harmful, perhaps that contribution is too trivial to render it morally impermissible. Against this view, there have been attempts to show that an individual’s lifetime emissions cause non-trivial harm, but in this paper I will consider what follows if it is true that an individual is not blameworthy (...) for her emissions. Specifically, I ask how a non-blameworthy emitter would best regard his or her own emissions. I will argue that the appropriate attitude to adopt here is one of agent-regret. This allows us to capture the moral disvalue of one’s emissions without entailing blame for them. *Links to the paper and video overview below.*. (shrink)

With the existing commitments to climate change mitigation, global warming is likely to exceed 2°C and to trigger irreversible and harmful threshold effects. The difference between the reductions necessary to keep the 2°C limit and those reductions countries have currently committed to is called the ‘emissions gap’. I argue that capable states not only have a moral duty to make voluntary contributions to bridge that gap, but that complying states ought to make up for the failures of some other (...) states to comply with this duty. While defecting or doing less than one’s fair share can be a good move in certain circumstances, it would be morally wrong in this situation. In order to bridge the emissions gap, willing states ought to take up the slack left by others. The paper will reject the unfairness-objection, namely that it is wrong to require agents to take on additional costs to discharge duties that are not primarily theirs. Sometimes what is morally right is simply unfair. (shrink)

Environmental ethicists have not reached a consensus about whether or not individuals who contribute to climate change have a moral obligation to reduce their personal greenhouse gas emissions. In this paper, I side with those who think that such individuals do have such an obligation by appealing to the concept of integrity. I argue that adopting a political commitment to work toward a collective solution to climate change—a commitment we all ought to share—requires also adopting a personal commitment to (...) reduce one’s emissions. On these grounds, individuals who contribute to climate change have a prima facie moral duty to lower their personal greenhouse gas emissions. After presenting this argument and supporting each of its premises, I defend it from two major lines of objection: skepticism about integrity’s status as a virtue and concerns that the resulting moral duty would be too demanding to be morally required. I then consider the role that an appeal to integrity could play in galvanizing the American public to take personal and political action regarding climate change. (shrink)

Abstract: This study has effectively tackled the critical challenge of accurate calorie prediction in dishes by employing a robust neural network-based model. With an outstanding accuracy rate of 99.32% and a remarkably low average error of 0.009, our model has showcased its proficiency in delivering precise calorie estimations. This achievement equips individuals, healthcare practitioners, and the food industry with a powerful tool to promote healthier dietary choices and elevate awareness of nutrition. Furthermore, our in-depth feature importance analysis has shed light (...) on the indispensable role played by specific nutritional attributes in calorie estimation. This unveiling of crucial factors provides valuable insights for further research endeavors and practical applications. Notably, this research extends its impact beyond the immediate context by making substantial contributions to the domains of nutrition science and dietary planning. It underscores the transformative potential of artificial intelligence, demonstrating how it can revolutionize our approach to food, nutrition, and health. As the world grapples with the challenges of diet-related health issues and environmental concerns, the accuracy and precision achieved in calorie prediction through neural networks represent a significant stride towards more informed and conscientious dietary practices. In this era of data-driven decision-making, our research paves the way for healthier lifestyles, heightened nutritional awareness, and a more health-conscious society. (shrink)

What requirements does morality impose on us in relation to climate change? This question can be asked of individuals, of the entire global population, and of groups of various sizes in between. Given the case for accepting that we all collectively ought to be causing less climate-affecting pollution than we do, what follows from that about the moral status of the actions of members of the larger group? I examine two main ways in which moral requirements on group members can (...) derive from requirements that apply to the larger group. But neither of them seems to apply to the case of climate-affecting pollution. Perhaps this is a case where we together act wrongly, although no-one’s contribution to our doing so is wrong. (shrink)

I investigate whether any plausible moral arguments can be made for ‘grandfathering’ emission rights (that is, for setting emission targets for developed countries in line with their present or past emission levels) on the basis of a Lockean theory of property rights.

[Opinion] This aims to begin deliberation about investing in negative emissions technologies (NETs) by suggesting that the investment could be responsive to two particular values: need and efficiency—and that these values point us towards taking different actions. For negative emissions technologies, I suggest, we face a Need-Efficiency Tradeoff, i.e. a “NET effect”. This tradeoff also highlights several contrasts: responding to need focuses on regional and short-term moral considerations; responding to efficiency focuses on global and long-term moral considerations. [Open (...) access]. (shrink)

Many suggest that we should look backward and measure the differences among various parties' past emissions of greenhouse gases to allocate moral responsibility to remedy climate change. Such backward-looking approaches face two key objections: that previous emitters were unaware of the consequences of their actions, and that the emitters who should be held responsible have disappeared. I assess several arguments that try to counter these objections: the argument from strict liability, arguments that the beneficiary of harmful or unjust (...) class='Hi'>emissions should pay, and arguments from distributive justice. I argue that none of these successfully justify a backward-looking approach to the temporally remote portion of the climate burden. (shrink)

Carbon offsetting remains contentious within, at least, philosophy. By posing and then answering a general question about an aspect of the morality of carbon offsetting—Does carbon offsetting make luxury emissions morally permissible?—this essay helps to lessen some of the topic’s contentiousness. Its central question is answered by arguing and defending the view that carbon offsetting makes luxury emissions morally permissible by counteracting potential harm. This essay then shows how this argument links to and offers a common starting point (...) for further examination of offsetting across various disciplines and domains, such as policy and other branches of philosophy like the ethics of risk.

Much of the climate ethics discussion centers on considerations of compensatory justice and historical accountability. However, little attention is given to supporting and defending the Beneficiary Pays Principle as a guide for policymaking. This principle states that those who have benefitted from an instance of harm have an obligation to compensate those who have been harmed. Thus, this principle implies that those benefitted by industrialization and carbon emission owe compensation to those who have been harmed by climate change. Beneficiary Pays (...) is commonly juxtaposed with Polluter Pays Principle and the Ability to Pay Principle in the relevant literature. Beneficiary Pays withstands objections that raise suspicion for the latter two. (shrink)

There has been a recent resurgence of what Betsy Hartmann dubbed “the greening of hate” (blaming immigrants for environmental issues in the US). When immigrants move to the U.S., the argument goes, their CO2 emissions increase, thereby making climate change worse. Using migration from the Lower 48 to Alaska as a model, I illustrate how this anti-immigration argument has more traction than it is generally given credit for, and might be more convincing in a different situation. Nonetheless, it is (...) not convincing given the current pattern of climate emissions and prevailing justice considerations. Climate matters; how we treat each other matters, too. (shrink)

Life is getting digital more than ever as technology improves. While the Internet is responsible for two percent of global greenhouse gas emissions, it is underestimated as a pollutant. Since public awareness is one of the most important preservation methods, it can contribute to protecting the environment from carbon emissions by raising people's understanding. In this regard, serious games, as a type of gamification transmitting educational content besides entertainment, immerse the player in enjoyment while teaching them a specific (...) topic or enhancing their skills in a field. This study proposes a serious game, taking the digital unseen carbon footprint and its effects on the landscape into the topic. The game considers SDG goals provided by the United Nations Department of Economic and Social Affairs. In this regard, the research uses SDGs 4 and 7 by providing quality education for all and access to sustainable energy by changing people's everyday habits. (shrink)

One of the ways that we could account for the unpredictability of the price elasticity of demand for carbon would be to provide a fail-safe mechanism to ensure that we definitely stay on the carbon reduction schedule. If we kept Energy Innovation Act (HR 763) essentially as it is and scale up the annual carbon fee increase by Number-of-Years-Behind-Schedule * 0.15.

Emissions grandfathering maintains that prior emissions increase future emission entitlements. The view forms a large part of actual emission control frameworks, but is routinely dismissed by political theorists and applied philosophers as evidently unjust. A sympathetic theoretical reconsideration of grandfathering suggests that the most plausible version is moderate, allowing that other considerations should influence emission entitlements, and be justified on instrumental grounds. The most promising instrumental justification defends moderate grandfathering on the basis that one extra unit of emission (...) entitlements from a baseline of zero emissions increases welfare to a greater extent where it is assigned to a high emitter than where it is assigned to a low emitter. Moderate grandfathering can be combined with basic needs and ability to pay considerations to provide an attractive approach to allocating emission entitlements. (shrink)

ABSTRACT We have previously argued that there are forms of greenhouse gas offsetting for which, when one emits and offsets, one imposes no risk. Orri Stefansson objects that our argument fails to distinguish properly between the people who stand to be harmed by one’s emissions and the people who stand to be benefited by one’s offsetting. We reply by emphasizing the difference between acting with a probability of making a difference to the distribution of harm and acting in a (...) way that worsen’s someone’s prospect. (shrink)

Much of the climate justice discussion revolves around how the remaining carbon budget should be globally allocated. Some authors defend the unjust enrichment interpretation of the beneficiary pays principle (BPP). According to this principle, those states unjustly enriched from historical emissions should pay. I argue that if the BPP is to be constructed along the lines of the unjust enrichment doctrine, countervailing reasons that might be able to block the existence of a duty of restitution should be assessed. One (...) might think that the duty to provide restitution no longer has moral weight if many benefits were already consumed, if the particular benefits obtained from historical emissions cannot be transferred from one country to another, or if present members of developed countries framed their life plans based upon the expectation of continued possession of those benefits. I show that none of these reasons negate the duty to provide restitution. (shrink)

A question arising from the COVID-19 crisis is whether the merits of cases for climate policies have been affected. This article focuses on carbon pricing, in the form of either carbon taxes or emissions trading. It discusses the extent to which relative costs and benefits of introducing carbon pricing may have changed in the context of COVID-19, during both the crisis and the recovery period to follow. In several ways, the case for introducing a carbon price is stronger during (...) the COVID-19 crisis than under normal conditions. Oil costs are lower than normal, so we would expect less harm to consumers compared to normal conditions. Governments have immediate need for diversified new revenue streams in light of both decreased tax receipts and greater use of social safety nets. Finally, supply and demand shocks have led to already destabilized supply-side activities, and carbon pricing would allow this destabilization to equilibrate around greener production for the long-term. The strengthening of the case for introducing carbon pricing now is highly relevant to discussions about recovery measures, especially in the context of policy announcements from the European Union and United States House of Representatives. Key Policy Insights: • Persistently low oil prices mean that consumers will face lower pain from carbon pricing than under normal conditions. • Many consumers are more price-sensitive during the COVID-19 context, which suggests that a greater relative burden from carbon prices would fall upon producers as opposed to consumers than under normal conditions. • Carbon prices in the COVID-19 context can introduce new revenue streams, assisting with fiscal holes or with other green priorities. • Carbon pricing would contribute to a more sustainable COVID-19 recovery period, since many of the costs of revamping supply chains are already being felt while idled labor capacity can be incorporated into firms with lower carbon-intensity.

This chapter concerns the nature of our obligations as individuals when it comes to our emissions-producing activities and climate change. The first half of the chapter argues that the popular ‘expected utility’ approach to this question faces a problematic dilemma: either it gives skeptical verdicts, saying that there are no such obligations, or it yields implausibly strong verdicts. The second half of the chapter diagnoses the problem. It is argued that the dilemma arises from a very general feature of (...) the view, and thus is shared by other views as well. The chapter then discusses what an account of our individual obligations needs to look like if it is to avoid the dilemma. Finally, the discussion is extended beyond climate change to other collective impact contexts. (shrink)

The statement that we are currently failing to address some of humanity’s greatest challenges seems uncontroversial—we are not doing enough to limit global warming to a maximum of 2 °C and we are exposing vulnerable people to preventable diseases when failing to produce herd immunity. But what singles out such failings from all the things we did not do when all are unintended? Unlike their individualist counterparts, collective inaction and omission have not yet received much attention in the literature. collective (...) inaction, I argue, can be attributed to a group of agents where a collective action x that the agents did not perform was collectively feasible at time t where each agent in that group had sufficient reason to contribute to performing x or others had a reasonable expectation that they would perform x. I show that, perhaps surprisingly, we can speak of collective inaction even where only one member of the group fails to act. However, where large and dispersed groups of agents are concerned, there is often no meaningful way of attributing collective failings. Still, I contend that the failure to close the global emissions gap and—in some cases—to generate herd immunity are indeed on us. (shrink)

In this book some options concerning the greenhouse effect are assessed from a welfarist point of view: business as usual, stabilization of greenhouse gas emissions and reduction by 25% and by 60%. Up to today only economic analyses of such options are available, which monetize welfare losses. Because this is found to be wanting from a moral point of view, the present study welfarizes (among others) monetary losses on the basis of a hedonistic utilitarianism and other, justice incorporating, welfare (...) ethics. For these welfarist evaluations information about the social consequences of the four options are collected from the literature and eventually corrected; then the consequences for individual well-being are assessed based on psychological research about well-being dependent on the social situation of the individual; finally the aggregation formulas of the respective welfare ethics are applied to these data. Assessments by other types of ethics, e.g. Kantian ethic, are included. The strongest abatement option is found to be optimum with great unanimity. - In addition a cost-welfare analysis of greenhouse gas abatement is undertaken revealing efficient cost-welfare ratios for these measures and the most efficient ratio for the strongest option. - A final, more theoretical part discusses the moral obligations following from such evaluations. The notion of 'moral obligation' is explained in a way that, apart from moral goodness of the required act, reinforcement by formal or informal sanctions is another necessary condition for moral obligations. This leads to a conception of a historical morality according to which the demands of morality rise in the long run. Applying this conception to the greenhouse effect implies that presently we have the moral duty to raise the standards of greenhouse gas abatement as much as is politically feasible. (shrink)

Action must be taken to combat climate change. Yet, how the costs of climate action should be allocated among states remains a question. One popular answer—the polluter-pays principle (PPP)—stipulates that those responsible for causing the problem should pay to address it. While intuitively plausible, the PPP has been subjected to withering criticism in recent years. It is timely, following the Paris Agreement, to develop a new version: one that does not focus on historical production-based emissions but rather allocates climate (...) burdens in proportion to each state’s annual consumption-based emissions. This change in carbon accounting results in a fairer and more environmentally effective principle for distributing climate duties. (shrink)

In Southeast Asian countries (SEA), road transport accounts for the main energy consumption and CO2 emission. Air pollution is a major concern in densely populated cities such as Bangkok, Manila, and Kuala Lumpur. The main objective of this paper is to give insights on trends of transport development, car ownership, and CO2 emissions in Southeast Asia. This study also attempts to review the successful transportation policies around the globe and to introduce the possible instruments that can help reduce air (...) pollution in Southeast Asian countries. Economic instruments to estimate the benefits of a cleaner environment due to new policies are introduced as well. The results of this research could help policy makers consider approaches that could internalize external costs of transportation and maximize the societal welfare. (shrink)

With the rapid development of information technology, the electricity consumption of Internet Data Centers (IDCs) increases drastically, resulting in considerable carbon emissions that need to be reduced urgently. In addition to the introduction of Renewable Energy Sources (RES), the joint use of the spatial migration capacity of IDC workload and the temporal flexibility of the demand of Electric Vehicle Charging Stations (EVCSs) provides an important means to change the carbon footprint of the IDC. In this paper, a sustainability improvement (...) strategy for the IDC carbon emission reduction was developed by coordinating the spatial-temporal dispatch flexibilities of the IDC workload and the EVCS demand. Based on the Minkowski sum algorithm, a generalized flexible load model of the EVCSs, considering traffic flow and Road Impedance (RI) was formulated. The case studies show that the proposed method can effectively increase the renewable energy consumption, reduce the overall carbon emissions of multi-IDCs, reduce the energy cost of the DCO, and utilize the EV dispatching potential. Discussions are also provided on the relationship between workload processing time delay and the renewable energy consumption rate. (shrink)

Climate change has become one of the most pressing problems that can threaten the existence and development of humans around the globe. Almost all climate scientists have agreed that climate change is happening and is caused mainly by greenhouse gas emissions induced by anthropogenic activities. However, some groups still deny this fact or do not believe that climate change results from human activities. This essay discusses the causes, significance, and skeptical arguments of climate change denialism, as well as the (...) roles of scientists and science communication in addressing the issues. Through this essay, we call for the active participation of scientists in science communication activities with the public, the opening of new science communication sectors specified for climate change, and more attention to social sciences and humanities in addressing climate change issues.

This short paragraph reminds us, humans, that our own activities, past and present, have triggered many of the grave environmental problems we have been facing.
