Ideal carbon tax policy is internationally coordinated, fully internalizes externalities, redistributes revenues to those harmed, and is politically acceptable, generating predictable market signals. Since nonideal circumstances rarely allow all these conditions to be met, moral issues arise. This paper surveys some of the work in moral philosophy responding to several of these issues. First, it discusses the moral drivers for estimates of the social cost of carbon. Second, it explains how national self-interest can block climate action and suggests (...) international policies—carbon border tax adjustments and carbon clubs—that can help address these concerns. Third, it introduces some of the social science literature about the political acceptability of carbon taxes before addressing a couple common public concerns about carbon taxes. Finally, it introduces four carbon revenue usage options, arguing that redistributive and climate compensation measures are most morally justified. [Open access]. (shrink)

The coronavirus disease 2019 (COVID-19) crisis ought to serve as a reminder about the costs of failure to consider another long-term risk, climate change. For this reason, it is imperative to consider the merits of policies that may help to limit climate damages. This essay rebuts three common objections to carbon taxes: (1) that they do not change behaviour, (2) that they generate unfair burdens and increase inequality, and (3) that fundamental, systemic change is needed instead of (...) class='Hi'>carbon taxes. The responses are (1) that there is both theoretical and empirical reason to think that carbon taxes do change behaviour, with larger taxes changing it to a greater extent; (2) that undistributed carbon taxes are regressive but distributing the tax receipts can alleviate that regressivity (and, in many cases, make the overall effect progressive); and (3) that while small changes for increasing democratic decision-making may be helpful, (fundamental) change takes time and the climate crisis requires urgent action. [Open access] //// -/- La crise de lamaladie à coronavirus 2019 (COVID-19) devrait servir de rappel sur les coûts de la non-prise en compte d’un autre risque à long terme, les changements climatiques. Pour cette raison, il est impératif de considérer lesmérites des politiques susceptibles de contribuer à limiter les changements climatiques. Cet essai réfute trois objections courantes aux taxes sur le carbone : (1) qu’elles ne changent pas les comportements (2) qu’elles génèrent des charges injustes et augmentent les inégalités, et (3) qu’un changement fondamental et systémique est nécessaire au lieu de taxes sur le carbone. Les réponses sont (1) qu’il existe des raisons à la fois théoriques et empiriques de penser que les taxes sur le carbone modifient effectivement les comportements, et que des taxes plus élevées les modifient dans une plus grande mesure; (2) que les taxes sur le carbone non distribuées sont régressives,mais que la distribution des recettes fiscales peut atténuer cette régressivité (et, dans de nombreux cas, rendre l’effet global progressif); et (3) que, bien que de petits changements pour l’amélioration de la prise de décision démocratique peuvent être utiles, un changement (fondamental) prend du temps et la crise climatique exige une action urgente.

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.

A uniform carbon tax with equal per capita dividends is usually advocated as a cost-effective way of reducing greenhouse gas (GHG) emissions without increasing, and in many cases even reducing, economic inequality, in particular because of the positive balance between the carbon taxes paid by the worse off and the carbon dividends they receive back. In this article, I argue that a uniform carbon tax reform is unjust regardless of how the revenue is used, because (...) it does not discourage the rich from indulging in wasteful emissions. This is at odds with a normative account of the distribution of the GHG budget that I define as emissions limitarianism, which is a climate derivative of economic limitarianism. Emissions limitarianism holds that, under low GHG budget conditions, emissions permits should not be used to achieve functionings that over-consume the GHG budget without producing significant welfare gains relative to the achievement of alternative functionings. Accordingly, I argue that a uniform carbon tax should be complemented by a limitarian carbon tax, which restricts the capabilities of the rich to achieve wasteful emission-generating functionings. The article adopts a methodological multi-level perspective on capabilities as a measure of welfare, distinguishing between basic, secondary and tertiary capabilities. (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 I maintain that a progressive and leftist carbon tax should be revenue-neutral through a dual policy package: first, it should use some revenues to offset price increases for the poor and middle classes; second, it should use the remaining part of revenues to lower taxes on labour income (both employed and self-employed income) for those below a middle-income threshold. I will briefly examine three reasons why such a revenue-neutral and dual-package carbon tax (RN-DP-CT) could (...) (and should) become central in the political agenda of the European Left – even though much of what I will suggest can reasonably hold also with respect to other countries. First, the tax wage on labour in the euro area is one of the highest in the world. Second, the revenue-neutral and dual policy package carbon tax will tax more capital that yields income without a proportional increase in labour demand, rather than capital that creates new job opportunities. Third, we live in societies that are highly unequal, hence I see no moral reason why a carbon tax reform should not aim, among other things, to take wealth away from the richest. (shrink)

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 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)

Environmental pollution and climate change have been considered the main environmental challenges affecting the world’s ecosystem, including that of South Africa. They cause poverty, land degradation, and health hazards. One of the leading causes and contributing factors of environmental pollution and climate change is carbon emissions into the atmosphere. As a way to curb these emissions, Carbon tax policy has been introduced in various countries, including South Africa. In 2019, a Carbon tax was introduced to assist South (...) Africa in delivering on the commitments made in the Paris Agreement in 2015. If the policy is effectively applied, it will raise revenues while reducing carbon dioxide emissions. Before and after introducing the Carbon tax policy in South Africa, there has been debate and discussion on its impact on the environment, economy, and society. Based on the debate and discussion, it has been observed that more attention is paid to the economic implications and benefits of the tax on South Africa than the ethical implications. Thus, this paper aims to contribute to the ongoing debate and discussion by ethically evaluating the Carbon tax policy in South Africa. (shrink)

We find that if all countries adopt the necessary uniform global carbon tax and then return the revenues to their citizens on an equal per capita basis, it will be possible to meet a 2 °C target while also increasing wellbeing, reducing inequality and alleviating poverty. These results indicate that it is possible for a society to implement strong climate action without compromising goals for equity and development.

In this paper, we argue that the All Affected Principle generates a puzzle when applied to carbon tax referendums. According to recent versions of the All Affected Principle, people should have a say in a democratic decision in positive proportion to how much the decision affects them. Plausibly, one way of being affected by a carbon tax referendum is to bear the economic burden of paying the tax. On this metric of affectedness, then, people who pollute a lot (...) are ceteris paribus more affected than people who don’t, because the former stands to pay more in carbon taxes than the latter. Consequently, people who pollute a lot receive large voting power, while people who pollute a little receive little voting power. This is a puzzling distribution of voting power for several reasons. First, it is instrumentally counterproductive if the goal is to rectify damages to the climate. Second, it introduces prudential incentives for everyone to pollute more to gain voting power. Third, the relative difference in voting power between people who pollute a lot and people who don’t is puzzling from a desert-based point of view, since the former often make a serious effort to avoid polluting, while the latter don’t.

Product configuration is a key enabling technology for mass customization production. Previous studies mainly focus on the solving technologies for obtaining a feasible configuration or optimal configuration but ignore environmental factors like CO2 emissions, especially the environmental regulations from international organizations. In this article, we address product configuration optimization problems considering both carbon cap and carbon tax regulations. A two-stage approach that combines both Particle Swarm Optimization and a greedy algorithm is presented to solve the product configuration problems (...) with carbon emission concerns. A case study of a configurable ranger-drilling machine is illustrated to demonstrate the effectiveness of the presented approach. The impacts of carbon cap and carbon tax regulations on configuration results are compared. Further, the models are extended to analyze the effects of single-sourcing and multisourcing on product configuration. The analysis shows that multisourcing in combination with carbon tax regulation can facilitate a manufacturer to provide more green and low-carbon customized products for customers. Numerical experiments are conducted to validate the effectiveness of the model and the efficiency of the proposed solution method. (shrink)

The three main types of policies for addressing climate change are command and control regulation, carbon taxes (or price instruments), and cap and trade (or quantity instruments). The first question in the ethics of carbon pricing is whether the latter two (price and quantity instruments) are preferable to command and control regulation. The second question is, if so, how should we evaluate the relative merits of price and quantity instruments. I canvass relevant arguments to explain different ways (...) of addressing these important policy questions, suggesting that carbon pricing is preferable to command and control regulation, and that price instruments have the theoretical edge over quantity instruments.

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.

While there are a variety of moral issues that relate to carbon pricing policies, I will focus on one that has received a large amount of attention: is carbon pricing unjust? Campaigners and civil society groups, especially those involved in environmental and climate justice spaces, have rejected carbon pricing as unjust. This claim deserves some discussion and, in this perspective, I discuss a few potential dimensions of justice that could be relevant to this claim. My goal is (...) to show that, for the most important dimensions of justice, distributive and procedural, carbon pricing is not unjust as a policy instrument for addressing climate change.

[Newspaper Opinion] Before the COVID-19 pandemic and the accompanying fall in oil prices, a carbon price would have been immediately painful for the countries that imposed it, but far better for everyone over the longer term. In this unprecedented moment, introducing a carbon price would be beneficial both now and for 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.

Climate change economists have called it “the most important number you’ve never heard of” and the “holy grail of climate economic analysis.” It is the social cost of carbon (SCC), and its purpose is to reflect—in one dollar figure—the harm caused by emitting a single ton of carbon dioxide into the atmosphere. The SCC is an essential concept for environmental cost-benefit analysis, and for the idea of an “optimal tax” on carbon emissions. It is also the subject (...) of fierce debate in the academic literature and in American politics. This book offers the most systematic analysis yet of the social cost of carbon, its theoretical basis, and its proper role in climate economics and climate policy design. It explains that the SCC is not one concept but four, each of which is addressed to a distinct task in climate economics. Moreover, these four concepts can be sorted into two families that correspond to the two main branches of welfare economics, social choice theory and general equilibrium theory. The book explains these radically different theoretical frameworks and how a mathematically identical pair of SCC concepts can emerge from each. It then argues that the analytical power of each SCC concept is limited by its inability to capture the full array of ethical considerations that bear on responsible climate policy. Despite these limitations, the book explains how at least some SCC concepts can and should be put to work in real-world climate change policy analysis. (shrink)

Sustainable development is an everlasting theme and lasting strategy in today’s era. Low-carbon economy is an inevitable approach to the implementation of sustainable development. Cold chain logistics has become one of the main sources of carbon emissions. However, in the research on location planning of cold chain logistics, the costs of carbon emissions have not been taken into consideration in previous studies. The two-stage stochastic optimization model was established based on the comprehensive consideration of transportation costs, time (...) penalty costs, and carbon emission costs. In this case, it is extremely difficult to deal with uncertainty in TSSO model. Therefore, this paper constructs a two-stage robust optimization model using data-driven method and robust optimization theory and verifies the validity of this model through an actual case. The application of this method to a cold chain logistics enterprise showed that the service level of logistics cannot be guaranteed by stochastic optimization model. In the TSRO model, the costs increase by 2.18% at the price of robustness, whereas logistics service level shows an upward trend. In the TSRO model, enterprises are forced to choose a better distribution path when carbon tax increases, which not only helps enterprises save costs but also achieves low-carbon environmental benefits.

Molti esperti concordano sul fatto che la pandemia di Covid-19 sia l'occasione giusta per iniziare a tassare l’anidride carbonica, ora che la domanda e quindi anche il prezzo dei combustibili fossili sono scesi. Tuttavia, la carbon tax continua ad essere vista con sospetto, soprattutto tra i progressisti, che temono che questa misura abbia effetti regressivi. Allo stesso tempo, i sostenitori di una carbon tax a entrate positive, che finanzi investimenti in progetti ecologici, rischiano di allarmare eccessivamente l’elettorato conservatore. (...) In questo articolo, sostengo dunque che una carbon tax neutra dal punto di vista delle entrate e che miri a ridurre il cuneo fiscale può combinare gli obiettivi redistributivi della sinistra europea, la lotta contro il cambiamento climatico e un’ampia accettabilità sociale. Tuttavia, il modo in cui la carbon tax viene proposta deve essere invertito: non più “mitigare il cambiamento climatico e così facendo raggiungere anche un secondo obiettivo sociale (in questo caso l'aumento del reddito salariale)”, ma “raggiungere un certo obiettivo sociale attraverso la tassazione dell’anidride carbonica”.

To reduce CO2 emissions requires greater reliance on renewable sources of energy for generating electricity, especially adoption of large-scale wind generation. This study investigates possible approaches and/or policies that increase efficient use of renewable energy and reduce greenhouse gas emissions in a cost effective manner. We develop a constrained optimization model of two electricity systems to identify the impact of increasing wind generating capacity and examine how carbon prices (taxes, allowances) impact the penetration of wind power into the (...) electricity grids. Rather than employ engineering cost functions, marginal cost functions are estimated using hourly offer data from the Alberta Electric System Operator. We determine optimal removal of coal generating facilities as greater levels of wind capacity are installed in an integrated Alberta-BC electricity system; and examine the economic costs and institutional incentives that affect the ability to store intermittent wind-generated power in BC’s hydro reservoirs during low demand. The marginal shadow price of storage is zero, whichindicates that there is more than enough water behind the dams given Alberta’s relatively small demand for storage and limited intertie transmission capacity.

Pigovian policy is developed in economic theory as an efficient resolution to externality problems. The use of this type of policy to resolve real-world externality problems, including climate change in the form of carbon taxes, assumes that the Pigovian policy result derived in theory holds in the real world. By examining the bridging conditions from theory to the real world, I argue that this assumption holds only in an ambiguously defined subset of externalities. It is thus unclear when (...) Pigovian policy could be coherently applied, which is problematic given its widespread use in critical policy contexts. (shrink)

Although debates over carbon taxes and trading schemes, over carbon offsets and compact fluorescents are important, our efforts to address the environmental challenges that we face will fall short unless and until we also set about the difficult work of reconceiving who we are and how we are related to our processive cosmos. What is needed, I argue, are new ways of thinking and acting grounded in new ways of understanding ourselves and our relationship to the world, (...) ways of understanding that recognize our fundamental interdependence and interconnection with everyone and everything in the cosmos, ways of understanding that recognize the intrinsic beauty and value of every form of existence. What is needed, I suggest, is a moral philosophy grounded in Alfred North Whitehead's philosophy of organism. It is the primary aim of this essay to defend the value of a moral philosophy inspired by Whitehead's organic, beauty-centered conception of reality. (shrink)

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.

How much should the present generations sacrifice to reduce emissions today, in order to reduce the future harms of climate change? Within climate economics, debate on this question has been focused on so-called “ethical parameters” of social time preference and inequality aversion. We show that optimal climate policy similarly importantly depends on the future of the developing world. In particular, although global poverty is falling and the economic lives of the poor are improving worldwide, leading models of climate economics may (...) be too optimistic about two central predictions: future population growth in poor countries, and future convergence in total factor productivity (TFP). We report results of small modifications to a standard model: under plausible scenarios for high future population growth (especially in sub-Saharan Africa) and for low future TFP convergence, we find that optimal near-term carbon taxes could be substantially larger. (shrink)

Existing estimates of optimal climate policy ignore the possibility that carbon tax revenues could be used in a progressive way; model results therefore typically imply that near-term climate action comes at some cost to the poor. Using the Nested Inequalities Climate Economy (NICE) model, we show that an equal per capita refund of carbon tax revenues implies that achieving a 2 °C target can pay large and immediate dividends for improving well-being, reducing inequality and alleviating poverty. In an (...) optimal policy calculation that weighs the benefits against the costs of mitigation, the recommended policy is characterized by aggressive near-term climate action followed by a slower climb towards full decarbonization; this pattern—which is driven by a carbon revenue Laffer curve—prevents runaway warming while also preserving tax revenues for redistribution. Accounting for these dynamics corrects a long-standing bias against strong immediate climate action in the optimal policy literature. (shrink)

This dissertation extends John Rawls’s mature theory of justice out to address the environmental challenges that citizens of liberal democracies now face. Specifically, using Rawls’s framework of political liberalism, I piece together a theory of procedural justice to be applied to a constitutional democracy. I show how citizens of pluralistic democracies should apply this theory to environmental matters in a four stage contracting procedure. I argue that, if implemented, this extension to Rawls’s theory would secure background environmental justice. I explain (...) why the theory can be viewed as a partially specified political conception of environmental pragmatism, and how it relates to public environmental policy and discourse. While the framework is anthropocentric, it is one that reasonable non-anthropocentrists can endorse. Using this theory, I argue that liberal democracies must take measures to secure basic environmental rights for all presently existing and future citizens. Measures must also be in place to secure a minimum of social goods (including environmental goods) that guarantees that all citizens (present and future) can exercise their basic rights and liberties. Moreover, disparities in environmental goods should only be tolerated if they arise in accord with Rawls’s principle of fair equality of opportunity. I discuss carbon taxes, as well as carbon allocation trading schemes. I also argue that free democracies should employ precautionary reasoning when attempting to meet the demands of background environmental justice. (shrink)

Solar radiation management (SRM) may help to reduce the negative outcomes of climate change by minimising or reversing global warming. However, many express the worry that SRM may pose a moral hazard, i.e., that information about SRM may lead to a reduction in climate change mitigation efforts. In this paper, we report a large-scale preregistered, money-incentivised, online experiment with a representative US sample (N = 2284). We compare actual behaviour (donations to climate change charities and clicks on climate change petition (...) links) as well as stated preferences (support for a carbon tax and self-reported intentions to reduce emissions) between participants who receive information about SRM with two control groups (a salience control that includes information about climate change generally and a content control that includes information about a different topic). Behavioural choices are made with an earned real-money endowment, and stated preference responses are incentivised via the Bayesian Truth Serum. We fail to find a significant impact of receiving information about SRM and, based on equivalence tests, we provide evidence in favour of the absence of a meaningfully large effect. Our results thus provide evidence for the claim that there is no detectable moral hazard with respect to SRM. [Open access]. (shrink)

Although the international community repetitively pledged considerable amounts of adaptation finance to the global South, only little has been provided so far. Different instruments have been proposed to generate more funding and this paper aims at identifying those that are most suitable to raise adaptation finance in a just way. The instrument assessment is based on the following main criteria: fairness, effectiveness and feasibility. The criteria are applied to four instruments: contributions from domestic budgets, international carbon taxes collected (...) at the national level, border tax adjustments as well as selling emissions allowances in domestic trading schemes. Domestic emission trading schemes and border tax adjustments achieve the best-or rather, the least bad-results. Two further findings are that instruments are unable make agents pay for past excessive emissions and that all instruments generate rather small amounts of funding. As a consequence of the latter, adaptation finance will continue to be highly insufficient in all likelihood. (shrink)

With the aggravation of population aging, home health care services are paid more and more attention by the elderly. Previous studies aim at improving service quality and reducing cost, ignoring the coordinated and sustainable development of the economy and environment. From the perspective of sustainable development, this paper first establishes a linear optimization model considering transportation, time, and carbon emission costs. However, the uncertainty of service demand is a very difficult problem for HHC research. Most of the previous studies (...) only consider the deterministic model, which has difficulty dealing with the uncertain situation. Therefore, a robust optimization model is proposed to resist uncertain disturbances by introducing a robust uncertain set response. The experimental results show that the increase of low-carbon transition cost only increases the total cost of the LO model but has a significant positive impact on the RO model. With the increase of uncertainty, the robust model will pay the cost of robustness, but it can obtain a higher service level. In addition, when the carbon tax increases, the total transportation cost does not increase but decreases, thus obtaining environmental benefits. When the carbon tax increases by 25%, the average total cost of using the RO model is reduced by 8.274%. The research results of this paper can provide enlightenment and reference for the low-carbon transformation of HHC enterprises. (shrink)

The complexity of supply chains means that it is difficult to tell where national security arguments begin and end. That may weaken some of the traditional arguments for free trade for the same reasons that we accept the difficulty of rational economic calculation in a socialist society. National security arguments for protectionism may not remain restricted to very small and manageable segments of the economy. Liberals and cosmopolitans will need to pay greater heed to these problems. This essay also considers (...) why complex supply chains may create problems for a carbon tax and for the notion of corporate social responsibility. (shrink)

[Comment] We believe that climate winners have a part to play in redressing the inequalities brought about by climate change—indeed, we think some of their winnings are not legitimate because they were unearned, lucky windfalls. But the matter must be considered carefully. First, we do not claim that all climate gains are illegitimate, meaning that climate justice does not warrant confiscating all climate gains wholesale. Next, and perhaps somewhat unintuitively (at first), we argue that some of the illegitimate gains should (...) be transferred to polluters—that is the unintuitive part—while the rest should be used to compensate those harmed by climate change.

Joseph Heath sometimes plays the role of a gadfly in climate and environmental ethics. He often defends conventional, economics-focused claims which rub many philosophers the wrong way—claims that are at the heart of issues raised in these pages, claims such as that discounting is justifiable, growth is good, or cost-benefit analysis is appropriate in liberal democracies. I think we can all agree that sophisticated defences of conventional positions play an important part in the ecosystem. For philosophers, a gadfly can challenge (...) entrenched conceptions. If we agree that these goals are worthwhile, then this book serves as a useful summary and synthesis of the ways Heath has ably defended conventional claims about climate policy. (shrink)

Climate ethics has been concerned with polluter pays, beneficiary pays and ability to pay principles, all of which consider climate change as a single negative externality. This paper considers it as a constellation of externalities, positive and negative, with different associated demands of justice. This is important because explicitly considering positive externalities has not to our knowledge been done in the climate ethics literature. Specifically, it is argued that those who enjoy passive gains from climate change owe gains not to (...) the net losers, but to the emitters, just as the emitters owe compensation to the net losers for the negative externality. This is defended by appeal to theoretical virtues and to the social benefits of generating positive externalities, even when those positive externalities are coupled with far greater negative externalities. We call this the Polluter Pays, Then Receives ('PPTR', or 'Peter') Principle. This principle is then applied at two levels in the context of Canada. [Open access]. (shrink)

Photo by Alex Guillaume on Unsplash Introduction The problem of climate change raises some important philosophical, existential questions. I propose a radical solution designed to provoke reflection on the role of humans in climate change. To push the theoretical limits of what measures people are willing to accept to combat it, an extreme population control tool is proposed: allowing people to reproduce only if they make a financial commitment guaranteeing a carbon-neutral upbringing. Solving the problem of climate change in (...) the long run by halting the procreation of human beings is controversial. In the absence of human beings and consequent climate change, other animals and plant species would benefit from an atmosphere more conducive to prolonging their existence and even improving their ability to thrive. If someone were to invent something to reverse the effects of climate change and improve animals’ lives, then human beings’ presence would be justified by the invention. Whether the propagation of the human species is beneficial to anyone or anything but human beings themselves is difficult to answer. Perhaps human beings are unfit to tackle this issue, being unable to judge it objectively. Managing Procreation: An alternative to Piecemeal Approaches Measures aimed at reducing greenhouse gases by nudging individuals and corporations may have a positive effect, but if their behavior is not climate neutral, they continue to contribute to climate change. Consequently, as long as the number of people increases, reducing greenhouse gases is at best a mitigation tool. If humans could rely solely on renewable energy, decreasing the population arguably would not be necessary. Significantly reducing the number of people appears to provide a solution to both problems: people who do not exist do not contribute to climate change, and renewable energy could meet the demand of a smaller population. One option is to let only those who produce the problem pay for its solution. One could determine the expected annual emission of greenhouse gases per person, assuming an average life expectancy, and calculate the costs to compensate them by, e.g., installing extra solar panels. Those expected costs could then be paid by the parents of each new person annually over the first eighteen years of that person’s life by dividing the total expected costs by eighteen. There are also practical difficulties. It would be difficult to determine the payment necessary. What should be done if a child has been born whose parents cannot afford to pay? In addition, child benefits could be canceled, contrary to recent incentives for child births instated in Italy,[1] where additional benefits will be made available to pay for childcare, and Hungary,[2] where women with four children or more will be exempted for life from paying income tax. A transition period could exist once the policy has been adopted, since it would be unreasonable to confront those who are already pregnant with costs they could not reasonably have expected. While the analysis is both hypothetical and theoretical, the impracticality is a noteworthy obstacle. There are several practical issues that cannot be addressed here, like the difficulty of calculating the added negative effects of each new individual and the unlikelihood that many citizens will support politicians who propose adopting policies that discourage having children. The upshot of what I have proposed is that climate change can be solved in the long run without financial costs to society as a whole, notwithstanding the transitional measures that would bring costs with them. Managing Procreation to Reduce Suffering Should this be deemed too harsh a stance, it is important to consider the basic issue of whether it is justified to introduce measures to reduce the number of people in an already overpopulated world, especially if climate change leads to additional suffering. One need not agree with Benatar, but his perspective must at least be taken seriously: It is curious that while good people go to great lengths to spare their children from suffering, few of them seem to notice that the one guaranteed way to prevent all the suffering of their children is not to bring those children into existence in the first place.[3] Benatar argues that non-existence is preferable to existence,[4] which raises the question why new people should be created at all. Those who question whether this planet will be habitable for future generations presuppose that such generations will exist. If people are not brought into existence, they may be said to be deprived of what life has to offer, but life must not be presupposed to be something positive. Whether this is the case in fact merits an inquiry of its own. A solution to the problem of climate change despite an increased population does not equate to a positive outcome since it merely means that something negative is removed. After all, solving the problem is not a means to an end, but a means to a means, the latter means being a means to a happy life, which does not automatically ensue from a solution to the problem. Benatar, as an anti-natalist, argues that procreation is morally wrong. His basic idea is that there is an asymmetry between pleasure and pain and that the pleasure that is not experienced by someone because that person does not exist is not something bad whereas the absence of pain that is not experienced – for the same reason – is something good.[5] Accordingly, “The reason why we do not lament our failure to bring somebody into existence is because absent pleasures are not bad.”[6] One may question whether such a perspective suffices to prove that coming into existence is always a harm, but the assertion that coming into existence exposes a new being to potential harm is clear. Objections A drawback of the proposed radical solution, placing the financial impediment on procreation, is that it will not solve climate change in the short run. A significant drop in the number of people may have a positive effect in the long run, but for now the behavior of the people in existence is the problem. Other climate change mitigation policies would necessarily continue. Additionally, there are important practical reasons to continue to procreate. The benefits for the elderly are paid for by the labor force. It is a problem that new generations are created as mere means to benefit older people. Perhaps more troubling, a pyramid scheme is created: by the time those people have themselves become old, a new labor force must have been brought into existence, a process that must presumably continue. If a consideration for people in developing countries to have children is that they cannot provide for themselves at an advanced age, while benefits are either lacking or insufficient, developed countries could collectively fund a pension scheme.[7] This may be low-cost if it is tailored to the living standard in the countries in question and given the life expectancy. Such a pension scheme should be predicated on the countries’ efforts in reducing the birth rate. If the labor force decreases, the economy may suffer. The focus on economic growth is arguably one of the causes of climate change, but if the number of people is reduced, the living standard does not have to be compromised, since the economy can then still grow. If fewer people began to use natural resources and nonrenewable energy at higher per capita rates, then the procreation might not be beneficial to the climate. It would need to be accompanied by regulations on use. One may also object that only wealthy people will be able to afford children. This is correct, but there is no right to have a child one cannot afford. The right to procreate does not entail the right to have as many children as one wants.[8] Yet in many countries, like the United States, it is a fundamental right that is constitutionally protected. There are numerous social, emotional, and even biological reasons why people choose to procreate. These may include the joy of having a family, the hope that children may bring in society, and the intergenerational transference of knowledge. People may have a strong desire to raise children or even a religious duty. If someone procures a sports car that is highly polluting, it would be justifiable to impose a tax in such a case. Many taxes and fines are imposed on corporate polluters. Procreation is significantly different but if the issue is regarded with some distance, then a climate change prevention tax could be appropriate. Some may argue that raising children is expensive already, which nonetheless does not deter people from having children. The tax I propose would be additional and specifically dedicated to carbon neutrality, but it would be difficult to predict whether it would discourage procreation. One last objection may be that for those now dedicated to sustainability for preserving the earth for the sake of future generations, there would be little or no incentive to continue any climate change mitigation efforts at all. If they sense they cannot afford to procreate, they may simply use every natural resource rather than save the earth for animals or for next generations. In a democracy, this problem does not exist if the majority can afford to procreate and agree with legislation on the basis of which such behavior is discouraged or punished. CONCLUSION Prior to their existence, there is no obligation to bequeath the earth to next generations. Such generations will only exist if they are actually created, and there is no obligation to create them. The lack of existence should not be confused with harm. Climate change provides an important reason to stem overpopulation. Ironically, fast rates of procreation may lead to the earth becoming uninhabitable for humans altogether. The radical solution that has been proposed here is an unrealistic scenario. For now, the average global birth rate is just over 18 per thousand people, but there is a need to ensure that the number of people is not greater than the planet can endure. While it is better to prevent problems than to solve them, the interest in procreation and its associated joys, usefulness, and cultural value make mass reduction in the population unlikely. Some countries have smaller average family size than others and can act as models for reducing population in a less radical way. The need to continue efforts to reduce climate change persists. Whether it would curb population growth or not, an additional financial burden applied to neutralizing each person’s offspring’s carbon footprint provides a meaningful thought exercise that could help alleviate the pressure on current climate mitigation strategies.

Cet article vise à justifier, puis à appliquer une éthique climatique centrée sur les intérêts des acteurs économiques. Après avoir expliqué pourquoi le changement climatique pose un problème important de motivation, je montre pour quelles raisons les incitations peuvent au moins partiellement y remédier. Je développe ensuite deux possibilités d’institutionnalisation de l’éthique des incitations. La première consiste en une taxe internationale augmentant progressivement le coût des émissions de dioxyde de carbone, un dispositif auquel il convient d’ajouter des subsides pour la (...) recherche, le développement et le déploiement des énergies renouvelables. La seconde consiste en un marché global du carbone qui vise également à décourager l’utilisation des combustibles fossiles et à encourager l’utilisation de sources alternatives d’énergie. L’objectif est de montrer qu’une éthique climatique prenant en compte le problème de la motivation est plus efficace qu’une position qui se limite aux devoirs moraux incombant aux consommateurs et producteurs, soit de réduire leurs émissions.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Climate Justice: Ethics, Energy, and Public PolicyWillis JenkinsClimate Justice: Ethics, Energy, and Public Policy James Martin-Schramm Minneapolis: Fortress Press, 2010. 232 pp. $20.00Religious ethicists are sometimes tempted to interpret climate change as symptomatic of a civilizational corruption so deep that practical responsibility seems nearly impossible. In its considered treatment of energy options and policy responses, [End Page 198] Climate Justice works to make applied Christian ethics competent to (...) address climate change. By interpreting political possibilities with Christian commitments to justice, the book makes a distinctively practical contribution to the literature on Christianity and climate; it lifts an important theological voice in the growing subfield of climate ethics.The book begins by elaborating the general notion of ecological justice into workable criteria. Martin-Schramm describes four basic norms of ecojustice (sustainability, sufficiency, participation, and solidarity), from which he develops twelve energy policy guidelines (e.g., equity, adequacy). He then specifies those guidelines into fourteen criteria by which to assess the justice of climate action (e.g., historical responsibility, emissions verifiability).Subsequent chapters use those criteria to evaluate policy options. A chief difficulty in applying them lies in the tension between intergenerational and intragenerational claims. Global climate negotiations founder on disagreements about these undeveloped, plural dimensions of justice. Martin-Schramm therefore deploys criteria with a balancing objective: to develop obligations to the future while recognizing claims of the present poor and vulnerable, and while keeping the result within the bounds of North American political viability.For example, Martin-Schramm recognizes that the criterion of historical responsibility indicates that the United States should bear about one-third of the costs of climate transition. But he finds that the resulting figure ($331 billion) so outstrips realistic acceptance that he rejects financial transfer in favor of a “national obligation wedge” in which the nation compensates by pledging to reduce future emissions. Since those emission reductions are unlikely apart from a price on carbon, Martin-Schramm argues that justice mandates a fossil fuel tax. With an eye to political viability, he proposes beginning with a modest $5/ton (for comparison, the Stern Report estimates the social costs of carbon at $85/ton).Controversy in the details matters to the whole project because the point of Martin-Schramm’s approach is that a meaningful climate ethic should guide contextual action. Yet other accounts of climate justice will find a scandal of modesty on those contextual points. Martin-Schramm’s climate justice entails less economic transformation than the “Northern structural adjustment” demanded by the Latin American Council of Churches. It is also less ecocentric than accounts from indigenous theologians arguing that justice warrants rights for species at risk of extinction, and perhaps for Earth itself.While Climate Justice is a self-consciously North American account, the criteria it develops would be different and work more critically were the underlying account of justice dialogically constructed across economic, political, and theological borders. Were it pragmatic, in the sense of arising from projects from across those borders, rather than applied deductively, a Christian climate ethic would likely produce an account of justice with more critical demands on industrial infrastructure and on ecological consciousness. [End Page 199]In its self-limitation, however, lies the book’s practical promise. Martin-Schramm wants justice to illuminate effective ways toward real responsibility. His criteria for justice imply that advocating for impossible goals, or for objectives that would imperil other conditions of social justice, would amount to injustice. Making ethics matter for climate change, he shows, requires understanding what justice can do in context.The open question for this book’s project is how a self-limited ethic of applied justice relates to the deeper processes of social transformation obviously needed for adequate response. Martin-Schramm closes with an account of his work reforming the energy economy of Luther College, which should inspire every reader with a sense of what persistent, informed, and contextual action can accomplish.Willis JenkinsYale Divinity SchoolCopyright © 2012 The Society of Christian Ethics...

Ce livre propose une interprétation inédite de la biologie d'Aristote. Il montre que, dans la démarche aristotélicienne, à côté de la pensée discursive, oeuvre une pensée visuelle qui élabore une représentation de l'organisation spatiale du corps vivant, apportant ainsi une contribution décisive à la définition des deux tâches majeures de l'enquête scientifique aristotélicienne: l'explication causale et la détermination des genres.

«È ancora necessario, oggi in Italia, sforzarsi di sottolineare l’importanza e l’attualità del pensiero di Jan Patočka?» – si chiede Mauro Carbone presentando questo volume.

Toujours déjà expressif, habité par la dimension du langage au moment même de l'expérience, le "visuel" est un champ à part entière où se croisent réel et imaginaire, et donc une nouvelle forme de compréhension de notre rapport au monde. En ce sens, les derniers travaux de Merleau-Ponty, par leur réflexion sur la question du visuel, remettent en cause la plupart des catégories par lesquelles nous avons coutume de "nommer" notre rapport au monde. Cette problématique se révèle particulièrement importante aujourd'hui. (...) Le développement continu des technologies optiques et médiatiques ne cesse d'ouvrir nos existences à des formes inédites de visualisation et d'expérience, et impose une compréhension renouvelée du statut contemporain des images. Convaincus que la pensée du dernier Merleau-Ponty peut contribuer de manière décisive à saisir ces enjeux, les dix auteurs des interventions recueillies dans ce volume des philosophes ainsi que des spécialistes internationaux des médias provenant de cinq pays différents proposent une réflexion collective particulièrement homogène et novatrice autour des croisements entre les notions de "visible" et de "visuel"."--Page 4 of cover.
