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)

This chapter introduces several distinctions relevant to what is called the “discounting problem”, since the issue is how (future) costs and benefits are discounted to make them comparable in present terms. The author defends the claim that there are good reasons to adopt Ramsey-style discounting in the context of climate change: the Ramsey rule is robust, flexible, and well-understood. An important distinction involved in discounting—“descriptivism” and “prescriptivism”—is discussed. It is argued that, even if we adopt prescriptivism, and accept that this (...) means there is need for moral experts in parameter assignments, there is a significant issue. The type of moral expertise required for the discounting problem will not involve knowledge of moral theory—thus making moral philosophy unhelpful in terms of making particular parameter assignments, despite these being substantive moral judgments.

We set out longtermist political philosophy as a research field by exploring the case for, and the implications of, ‘institutional longtermism’: the view that, when evaluating institutions, we should give significant weight to their very long-term effects. We begin by arguing that the standard case for longtermism may be more robust when applied to institutions than to individual actions or policies, both because institutions have large, broad, and long-term effects, and because institutional longtermism can plausibly sidestep various objections to individual (...) longtermism. We then address points of contact between longtermism and some central values of mainstream political philosophy, focusing on justice, equality, freedom, legitimacy, and democracy. While each value initially seems to conflict with institutional longtermism, we find that these conflicts are less clear-cut upon closer inspection, and that some political values might even provide independent support for institutional longtermism. We end with a grab bag of related questions that we lack space to explore here. (shrink)

There is a common belief that genuine awareness and acceptance of the existence of anthropogenic climate change (as opposed to either ignorance or denial) automatically leads one to develop political and moral positions which advocate for collective human action toward minimizing suffering for all and adapting human societies toward a fossil-free future. This is a mistake. Against the idea that scientific awareness of the facts of climate change is enough to motivate a common ethical project of humanity toward a unifying (...) good, I argue that climate change awareness can just as well equally motivate heightened divisions of humanity into anti-egalitarian, xenophobic, class-differentiated zones of competitive survival. I call this climate barbarism, and seek to explain its conceptual grounds. (shrink)

Este artigo é uma breve introdução à filosofia da linguagem. Ele se concentra nos problemas que surgem a partir de dois conceitos centrais: referência e significado. Em particular, o foco central é no problema fundacional da referência e no problema descritivo do significado, assim como a relação entre eles. Embora esta de modo algum seja uma introdução exaustiva ao tema, muitos conceitos centrais são clarificados, como por exemplo teoria da referência, termo singular, termo geral, teoria do significado, composicionalidade, conteúdo, significado (...) linguístico, implicatura conversacional, vagueza, etc. Espera-se que sirva como um primeiro contato com a disciplina, principalmente voltado a estudantes de filosofia, filosofia da linguagem e áreas afins.

It is often stated that optimal global climate policy requires global harmonization of marginal abatement costs – i.e., a single carbon price throughout the world. Chichilnisky and Heal (1994) have shown quite generally that this is only the case if distributional issues are ignored, or if lump-sum transfers are made between countries. Else, a policy in which different regions face different carbon prices may be superior to one with a single global carbon price from a welfare point of view. Still, (...) most integrated assessment models (IAMs) assume away distributional issues and report a single optimal carbon price. We calculate utilitarian-optimal carbon prices under zero cross-regional lump-sum transfers in the multi-region IAM NICE. The result is optimal global climate policy with different regional carbon prices in which the poorest regions face initially low prices, while the richest regions face very high prices from the outset. This entails significant welfare gains over the standard single price optima commonly reported, which, as we argue briefly in conclusion, can be improved upon still by allowing international trading in the corresponding emissions allocations.

Work on global ethics looks at ethical connections on a global scale. It should link closely to environmental ethics, recognizing that we live in unified social-ecological systems, and to development ethics, attending systematically to the lives and interests of contemporary and future poor, marginal and vulnerable persons and groups within these systems and to the effects on them of forces around the globe. Fulfilling these tasks requires awareness of work outside academic ethics alone, in other disciplines and across disciplines, in (...) public debates and private agendas. A relevant ethics enterprise must engage in systematic description and understanding of the ethical stances that are expressed or hidden in the work of influential stakeholders and analysts, and seek to influence and participate, indeed embed itself, in the expressed and hidden choice-making involved in designing and conducting scientific research and in policy analysis and preparation; it will contribute in value-critical and interpretive policy analysis. It will explore how the allocation of attention and of concern in research and policy depend on perceptions of identity and of degrees of interconnection, and are influenced by the choice or avoidance of humanistic interpretive methodologies. The paper illustrates these themes with reference to the study of climate change. (shrink)

The language of ‘human security’ arose in the 1990s, including from UN work on ‘human development’. What contributions can it make, if any, to the understanding and especially the valuation of and response to the impacts of climate change? How does it compare and relate to other languages used in describing the emergent crises and in seeking to guide response, including languages of ‘externalities’, public goods and incentives, cost-benefit and cost-effectiveness analysis? The paper examines in particular the formulations in those (...) terms in Stiglitz's Making Globalization Work and Stern's The Economics of Climate Change and Blueprint for a Safer Planet, and how these authors are left groping for frameworks to motivate the changes required for global sustainability. It undertakes comparison also with the languages of human development and human rights, and suggests that, not least through enriching our skills of ‘narrative imagination’, the human security framework supports a series of essential changes in orientation—in our conceptions of selfhood, well-being and situatedness in Nature—and supports a required greater solidarity and greater awareness of our inter-connectedness.

The argument has been made that future generations of human beings are being harmed unjustifiably by the actions individuals commit today. This paper addresses what it might mean to harm future generations, whether we might harm them, and what our duties toward future generations might be. After introducing the Global Health Impact (GHI) concept as a unit of measurement that evaluates the effects of human actions on the health of all organisms, an incomplete theory of human justice is proposed. Having (...) shown that the negative GHIs of our current generation cause unfair harm to future generations, I argue that each human being must be allocated a fair threshold of negative GHIs that should not be exceeded. By emphasising the need to consider all the GHIs of human actions, the theory of human justice developed here is highly relevant to evaluate human actions that might affect future generations, for example those related to climate change.

In a previous work, I argued that all human beings should possess the right to adequate health protection and that we have good reasons to believe that not all human beings are or will be able to enjoy this right. I introduced the ?Global Health Impact? or ?GHI? concept as a unit of measurement to evaluate the effects of human actions on the health of human and nonhuman organisms and argued that the negative GHIs produced by our current generation jeopardise (...) the right to adequate health protection of future generations unjustifiably. In this article, this incomplete theory of human justice is applied to the negative GHIs associated with the consumption of farmed animal products. Since the negative GHIs of such products generally exceed those associated with other diets, I argue that those who exceed their fair share of negative GHIs might curtail their consumption and that the costs of reducing negative GHIs in this domain might be lower than the costs associated with other things that could be done to reduce negative GHIs.

The prominent burden-sharing principles in the emerging literature of the political theory of climate change fail to sufficiently tackle the task they set out to solve. This paper sets out properties that an alternative principle should aim to meet. Based on these properties, it develops a consequentialist moral principle – the wastefulness principle. This principle holds that it is wrong to waste a shared, scarce resource. The paper argues that this principle can be used to solve the question of who (...) should bear the burdens of anthropogenic climate change in a more suitable way than existing principles. After developing the wastefulness principle, this paper discusses in a non-exhaustive manner how it can be employed in the real world, which challenges it might meet, and how additional principles might solve them.

Ramsey famously condemned discounting “future enjoyments” as “ethically indefensible”. Suppes enunciated an equity criterion which, when social choice is utilitarian, implies giving equal weight to all individuals’ utilities. By contrast, Arrow accepted, perhaps reluctantly, what he called Koopmans’ :287–309, 1960) “strong argument” implying that no equitable preference ordering exists for a sufficiently unrestricted domain of infinite utility streams. Here we derive an equitable utilitarian objective for a finite population based on a version of the Vickrey–Harsanyi original position, where there is (...) an equal probability of becoming each person. For a potentially infinite population facing an exogenous stochastic process of extinction, an equitable extinction biased original position requires equal conditional probabilities, given that the individual’s generation survives the extinction process. Such a position is well-defined if and only if survival probabilities decline fast enough for the expected total number of individuals who can ever live to be finite. Then, provided that each individual’s utility is bounded both above and below, maximizing expected “extinction discounted” total utility—as advocated, inter alia, by the Stern Review on climate change—provides a coherent and dynamically consistent equitable objective, even when the population size of each generation can be chosen.

In this article I propose to explore two issues. The first concerns what kinds of contributions academics can make to reducing poverty. I argue that academics can contribute in a number of ways, and I seek to spell out the diversity of the options available. I concentrate on four ways in which these contributions might differ.My second aim is to outline some norms that should inform any academic involvement in activities that seek to reduce poverty. I set out six proposals. (...) These concern: (1) the need to construct coalitions among people with different ethical frameworks; (2) the value of constructing nonideal theory on the basis of our best understanding of an ideal world; (3) the need for integrated analysis that connects antipoverty initiatives to other areas of moral concern; (4) the vital importance of interdisciplinarity; (5) the need for epistemic modesty and revisability; and (6) the need for accountability.

I address options for providing scientific policy advice and explore the relation between scientific knowledge and political, economic and moral values. I argue that such nonepistemic values are essential for establishing the significance of questions and the relevance of evidence, while, on the other hand, such social choices are the prerogative of society. This tension can be resolved by recognizing social values and identifying them as separate premises or as commissions while withholding commitment to them, and by elaborating a plurality (...) of policy packages that envisage the implementation of different social goals. There are limits to upholding the value-free ideal in scientific research. But by following the mentioned strategy, science can give useful policy advice by leaving the value-free ideal largely intact. Such scientific restraint avoids the risk of appearing to illegitimately impose values on the public and could make the advice given more trustworthy. (shrink)

Drawing a link between energy policy and sustainable development, this paper explores the normative dimensions of policy analysis that inform energy sector decision-making, and how these norms fall short of incorporating adequate considerations of sustainability. The discussion focuses on the obligations that our present generation has to conserve for future generations, the decision of which discount rate to use, and the importance of citizen-oriented preferences in economic valuation. This analysis concludes with the claim that if sustainability insights are applied to (...) conventional methods of approaching these issues, we may be better prepared to address issues that are unconventional and complex, such as those involving the production and use of energy resources.

The aim of this article is to analyse environmental reporting in the Australian broadsheet newspaper The Sydney Morning Herald. The focus is on a particular kind of new, multisemiotic news story genre that appears regularly in this newspaper, and that makes use of word-image play. Using a social semiotic framework and employing Appraisal theory, we analyse a corpus of 40 stories in terms of evaluative meanings in heading, image and caption, and interpret the significance of our findings in terms of (...) both Critical Discourse Analysis and Positive Discourse Analysis. In particular, we question whether the playing with environmental stories in the news, and the resulting clash between the humorousness of the play and the seriousness of the reported environmental event, is good or bad practice. With its multisemiotic focus, this article aims to make a significant and innovative contribution to the emerging field of ecolinguistics, and the development of Appraisal theory. (shrink)

Climate change is projected to have very severe impacts on future generations. Given this, any adequate response to it has to consider the nature of our obligations to future generations. This paper seeks to do that and to relate this to the way that inter-generational justice is often framed by economic analyses of climate change. To do this the paper considers three kinds of considerations that, it has been argued, should guide the kinds of actions that one generation should take (...) if it is to treat both current and future people equitably. In particular it examines the case for what has been termed pure time discounting, growth discounting and opportunity cost discounting; and it assesses their implications for climate policy. It argues that none of these support the claims of those who think they give us reason to delay aggressive mitigation policies. It also finds, however, that the second kind of argument can, in certain circumstances, provide support for passing on some of the costs of mitigation to future generations. (shrink)

This paper argues that a combination of increasing inequality, hypocrisy, population growth and adverse global environmental change imperils our civilisation. Selected examples of existing inequality and the immoral treatment of human beings are provided from countries of the Asia Pacific. There is also limited discussion of the global eco-social crisis, stressing the links between environmental scarcity and the human responses of resentment, conflict, terrorism and ill-governance. The essay contends that just as the lives of unborn humans similar to us are (...) of interest and value to bio-ethicists, so too should be the lives and descendants of people who are unlike us, even if such people are perceived to be substantially different to ourselves in terms of status, culture and spending power. It is argued that it is in the interests of ourselves, society, and global civilisation that the lives of such people are considered and where possible improved in order to foster the “sustainability transition” needed to secure our collective future. The essay concludes with a discussion of an important element for securing our future: the development and implementation of alternative economic systems which will provide more accurate indicators of global progress.

This study adds two new perspectives to the long-running debate regarding the linkage between corporate social performance (CSP) and corporate financial performance (CFP): First, we add the aspect of issue materiality and suggest research to put more emphasis on the question of how individual CSP issues can be assumed to systematically influence the business environment from a theoretical point of view. Second, we highlight the measurement level of the underlying data screens as an important determinant of the actual effects of (...) CSP on CFP. Focusing on climate change, we developed a set of questions that cover a firm’s carbon emissions and carbon management strategies. These questions were included in a questionnaire sent out annually to the 2,500 largest companies by market cap within the Dow Jones Global Index by an independent Swiss-based asset management firm. Our results show that when using carbon emissions as an outcome-based measurement, corporate environmental performance pays off. Conversely, when using carbon management as a process-based measurement, we find a negative relationship between corporate environmental performance and CFP. (shrink)

The role of uncertainty within an organization’s environment features prominently in the business ethics and management literature, but how corporate investment decisions should proceed in the face of uncertainties relating to the natural environment is less discussed. From the perspective of ecological economics, the salience of ecology-induced issues challenges management to address new types of uncertainties. These pertain to constraints within the natural environment as well as to institutional action aimed at conserving the natural environment. We derive six areas of (...) ecology-induced uncertainties and propose ecology-driven real options as a conceptual approach for systematically incorporating these uncertainties into strategic management. We combine our results in an integrative investment framework and illustrate its application with the case of carbon constraints. (shrink)

Many fine-grained decisions concerning climate change involve significant, even severe, uncertainty. Here, we focus on modelling the decisions of single agents, whether individual persons or groups perceived as corporate entities. We offer a taxonomy of the sources and kinds of uncertainty that arise in framing these decision problems, as well as strategies for making a choice in spite of uncertainty. The aim is to facilitate a more transparent and structured treatment of uncertainty in climate decision making.

This paper examines the structure of moral responsibility for outcomes. A central feature of the analysis is a condition that we term the ‘avoidance potential’, which gives precision to the idea that moral responsibility implies a reasonable demand that an agent should have acted otherwise. We show how our theory can allocate moral responsibility to individuals in complex collective action problems, an issue that sometimes goes by the name of ‘the problem of many hands’. We also show how it allocates (...) moral responsibility in the classic Frankfurt example. (shrink)

Development scholars and practitioners are promoting food security, food sovereignty, and the localization of food systems to prepare for the projected negative impacts of climate change. The implementation of biodiverse homegardens is often seen as a way not only to localize food production but also as a strategy in alignment with a food sovereignty agenda. While much scholarship has characterized and critiqued food security and sovereignty conceptualizations, relatively little research has examined people’s lived experiences in order to test how such (...) theoretical visions play out on the ground in farming communities. Based on a case study of four coffee cooperatives in northern Nicaragua, we examine a non-governmental organization (NGO)-supported project promoting food security and sovereignty through development of homegardens. We ask: To what extent are homegardens an effective strategy to reach food sovereignty? And, why may farmers be resistant to changing their food production and consumption strategies to embrace biodiverse homegardens when they improve food security? We discuss characteristics of agroecological homegardens, the distinctions between food security, food sovereignty and dominant discourses of development, the history of food sovereignty in Nicaragua, and farmer perspectives on homegarden implementation. Despite historic critiques, NGOs are poised to facilitate the transformation of food and agricultural development by employing counter development strategies, a necessary step if homegardens are to be successful in the long term. To conclude, we propose some strategies NGOs and communities might pursue to move forward with homegardens as a food sovereignty strategy. This research suggests that a food sovereignty approach still rooted in mainstream development models faces significant obstacles to moving beyond food security and into a farmer-led food sovereignty agenda.

Climate policy decisions are decisions under uncertainty and are, therefore, based on a range of future climate scenarios, describing possible consequences of alternative policies. Accordingly, the methodology for setting up such a scenario range becomes pivotal in climate policy advice. The preferred methodology of the Intergovernmental Panel on Climate Change will be characterised as ,,modal verificationism"; it suffers from severe shortcomings which disqualify it for scientific policy advice. Modal falsificationism, as a more sound alternative, would radically alter the way the (...) climate scenario range is set up. Climate science's inability to find robust upper bounds for future temperature rise in line with modal falsificationism does not disprove that methodology, rather, this very fact prescribes even more drastic efforts to curb CO2 emissions than currently proposed.

The urgent importance of dealing with the climate crisis has led some influential theorists to argue that at least some demands for justice must give way to pragmatic and strategic considerations. These theorists (Cass Sunstein, Eric Posner, and David Weisbach, all academic lawyers, and John Broome, an academic philosopher) contend that the failures of international negotiations and other efforts to change economic policies and practices have shown that moral exhortations are worse than ineffective. Although Broome's position is similar in these (...) respects to that of Sunstein, Posner and Weisbach, it differs in other important respects, including his understanding of the idea of justice, his disagreement with the policy approach (which he calls "efficiency with sacrifice") favored by the economists Nicholas Stern and William Nordhaus, and his proposal for establishing a new international financial institution, a World Climate Bank, in addition to putting a price on carbon. Elsewhere I offer a critical analysis of the position taken by Posner and Weisbach in their book, Climate Change Justice. Their arguments against allowing principles of distributive justice (narrowly understood) to constrain treaty negotiations fail to rule out the principles of John Rawls' Law of Peoples (which is a conception of the moral basis of a just international order, including states' obligations to secure basic human rights for all). Therefore their arguments against shaping climate treaties to reflect any principles of justice do not succeed in supporting their position. Here I offer a critical analysis of Broome's position. I raise and discuss objections to Broome's proposal for a WCB, and I argue that the continued relevance of these objections is contingent on how the proposal for a WCB may get developed. (shrink)

Countries are ranked on many criteria, the results of which can have far-reaching ethical and practical implications, particularly for emerging nations seeking role models. One highly influential ranking, the World Economic Forum’s Global Competitiveness Report, has been criticized for containing multiple methodological, conceptual, and logical flaws that bias competitiveness rankings toward countries that favor neoliberalism. Using datasets not afflicted by such flaws, we examine Bergsteiner and Avery’s :391–410, 2012) prediction that competitiveness scores of the USA and the UK are substantially (...) overstated. Results of re-ranking 104 countries using 29 economic, environmental, and social datasets from reputable sources support this assertion, with the USA showing the greatest discrepancy on a 100-point scale between its 2013–2014 GCR score and our study’s 2013 score, and the UK falling from GCR score 9 to 40. We explore reasons for this discrepancy, including examining the relationship between a country’s neoliberal traditions and its rankings on the indicators. (shrink)

Early discussions of ?climate justice? have been dominated by economists rather than political philosophers. More recently, analytical liberal political philosophers have joined the debate. However, the philosophical discussion of climate justice remains in its early stages. This paper considers one promising approach based on human rights, which has been advocated recently by several theorists, including Simon Caney, Henry Shue and Tim Hayward. A basic argument supporting the claim that anthropogenic climate change violates human rights is presented. Four objections to this (...) argument are examined: the ?future persons? objection; the ?risk? objection; the ?collective causation? objection; and the ?demandingness? objection. This critical examination leads to a more detailed specification and defence of the claim that anthropogenic climate change violates human rights. (shrink)

Cost-benefit analysis (CBA) evaluates actions in terms of negative consequences (costs) and positive consequences (benefits). Though much has been said on CBA, little attention has been paid to the types of values held by costs and benefits. This paper introduces a simple typology of values in CBA and applies it to three forms of CBA: the common, money-based CBA, CBA based in social welfare, and CBA based in intrinsic value. The latter extends CBA beyond its usual anthropocentric domain. Adequate handling (...) of value typology in CBA avoids analytical mistakes and connects CBA to its consequentialist roots. (shrink)

In a recent editorial, Raymond Spier expresses skepticism over claims that climate change is driven by human actions and that humanity should act to avoid climate change. This paper responds to this skepticism as part of a broader review of the science and ethics of climate change. While much remains uncertain about the climate, research indicates that observed temperature increases are human-driven. Although opinions vary regarding what should be done, prominent arguments against action are based on dubious factual and ethical (...) positions. Thus, the skepticisms in the recent editorial are unwarranted. This does not diminish the general merits of skeptical intellectual inquiry. (shrink)

This study focuses on implementing electric vehicles (EVs) in developing countries where energy production is mainly based on fossil fuels. Although for these countries the environmental short-run benefits of the EVs cannot offset the short-run costs, it may still be the best option to implement the EVs as soon as possible. Hence, it is necessary to evaluate the alternatives to introducing EVs to the market due to the environmental concerns that created an opportunity for some developing countries to catch up (...) with the international competition. Therefore, we develop a case scenario to explore the decision-making process in implementing the EVs with three alter natives and twelve criteria. We solve the decision-making problem by using Type-2 neutrosophic numbers (T2NNs) based on the RAFSI (Ranking of Alternatives through Functional mapping of criterion sub-intervals into a Single Interval) method. The proposed model combines the advantages of the RAFSI technique, and it applies T2NNs to address the uncertainties. The results show that the alternatives that may suspend the implementation of the EVs are inferior. Direct implementation of EVs is prioritized. The policy implications of the results are discussed in the study. (shrink)

ABSTRACT Conceptual engineering aims to improve our concepts. That's plausibly an extremely difficult thing to do. Should this make us sceptical of the idea that philosophers should try to do it? You might think so. Cappelen, in his Fixing Language: an Essay on Conceptual Engineering, thinks it shouldn't stop us – but his stated reasons are not really encouraging. In this paper, I say what I think Cappelen should have said, on the basis of a very rough cost-benefit analysis.

Temporal discounting is a technical operation in climate change economics. When discount rates are positive, economic evaluation treats future benefits as less important than equivalent present benefits. This chapter explains and critically evaluates four different reasons economists have given for tying discount rates to the interest rates we observe in real-world markets. I suggest that while philosophers have correctly criticized three of these reasons, their criticisms of the fourth miss the mark. This is because philosophers have not taken heed of (...) the distinct analytical framework in which the fourth reason arises. (shrink)

In this chapter we first discuss the main principles of justice and note the standard objections to them, which we believe necessitate a hybrid approach. The hybrid account we defend is primarily based on the distributive principle of sufficientarianism, which we interpret as the idea that each country should have the means to provide a minimally decent quality of life for each of its citizens. We argue that sufficientarian considerations give good reason to think that what we call the ‘ability (...) to pay objection’ should be taken much more seriously in this debate. Following this, our account emphasises what we believe are the two most important moral desiderata in any attempt to distribute responsibility for dealing with climate change: the ability to mitigate the problem and the making of culpable contributions to the problem. After noting that our proposal includes enough detail to be a useful start for policy makers, we defend our account against some potential objections. (shrink)

«Je propose ici de comprendre cette nouvelle constellation du monde global comme la dialectique entre le tous et le personne pour expliquer ce que je désignerai, de façon métaphorique, le retour de la piraterie dans cette nouvelle ère de la globalisation.» - Daniel Innerarity.

Global climate change raises profound questions for social and political theorists. The human impacts of climate change are sufficiently broad, and generally adverse, to threaten the rights and freedoms of existing and future members of all countries. These impacts will also exacerbate inequalities between rich and poor countries despite the limited role of the latter in their origins. Responding to these impacts will require the implementation of environmental and social policies that are both environmentally effective and consistent with the equality (...) and liberty of populations to which they are applied. This article considers whether global emissions trading, namely, the creation of a global market for tradable allowances conferring the right to emit a certain amount of greenhouse gas over a specified time period, is normatively defensible from a liberal egalitarian perspective. After a brief review of the theory and practice of emissions trading, a number of normative objections to the international trade in emissions allowances are analysed. These objections appeal to one, or a combination, of two claims. First, emissions trading schemes are likely to produce undesirable outcomes, such as environmental neglect, in the further future. I call these ‘instrumental objections’. Second, emissions trading schemes violate non‐consequential norms of justice and fairness. I call these ‘intrinsic objections’. It is argued that, when combined, instrumental and intrinsic objections indicate that instituting a global network of emissions trading schemes, as envisioned by a number of parties to the Kyoto Protocol and Copenhagen Accord, would be illegitimate in absence of significant procedural and consequential safeguards.

In this chapter, we argue that in order to understand the interdisciplinary and transdisciplinary dialectics in sustainability science, it is useful to see sustainability science as a kind of management science, and then to highlight the hard-soft distinction in systems thinking. First, we argue that the commonly made natural-social science dichotomy is relatively unimportant and unhelpful. We then outline the differences between soft and hard systems thinking as a more relevant and helpful distinction, mainly as a difference between perspectives in (...) systemic modeling toward models. We also illustrate that the distinction is methodologically useful to advance sustainability science by enabling us (i) to suggest novel ways of using existing theoretical, experimental, and computational resources of the sciences for renewable resource management, and (ii) to disentangle disciplinary disagreements in climate science.

In this essay we develop and argue for the adoption of a more comprehensive model of research ethics than is included within current conceptions of responsible conduct of research (RCR). We argue that our model, which we label the ethical dimensions of scientific research (EDSR), is a more comprehensive approach to encouraging ethically responsible scientific research compared to the currently typically adopted approach in RCR training. This essay focuses on developing a pedagogical approach that enables scientists to better understand and (...) appreciate one important component of this model, what we call intrinsic ethics . Intrinsic ethical issues arise when values and ethical assumptions are embedded within scientific findings and analytical methods. Through a close examination of a case study and its application in teaching, namely, evaluation of climate change integrated assessment models, this paper develops a method and case for including intrinsic ethics within research ethics training to provide scientists with a comprehensive understanding and appreciation of the critical role of values and ethical choices in the production of research outcomes.

Both modernist and post-modern social criticism of power presuppose that agents frequently consent to power relations, which a political theorist may wish to critique. This raises the question: from what normative position can one critique power which is, as a sociological fact, legitimate in the eyes of those who reproduce it? This paper argues that "symbolic violence" is a useful metaphor for providing such a normative grounding. In order to provide an epistemological basis of critique, it is further argued that (...) social actors have multiple interpretative horizons available to them as part of their everyday social practices. Thus, they are not caught in a preconstituted web of meaning from which there is no escape, as is sometimes implicit in the over-socialized perceptions of agency associated with post-modernism.

The social cost of carbon (SCC) is a central concept in climate change economics. This chapter explains the SCC and investigates it philosophically. As is widely acknowledged, any SCC calculation requires the analyst to make choices about the infamous topic of discount rates. But to understand the nature and role of discounting, one must understand how that concept—and indeed the SCC concept itself—is yoked to the concept of a value function, whose job is to take ways the world could be (...) across indefinite timespans and to rank them from better to worse. A great deal, therefore, turns on the details of the value function and on just what is meant by “better” and “worse.” This chapter seeks to explicate these and related issues, and then to situate them within the evolving landscape of federal climate policy in the United States.

In a very general sense, hybrid can be understood to be any organism that is the product of two (or more) organisms where each parent belongs to a different kind. For example; the offspring from two or more parent organisms, each belonging to a separate species (or genera), is called a “hybrid”. “Hybridity” refers to the phenomenal character of being a hybrid. And “hybridization ” refers to both natural and artificial processes of generating hybrids. These processes include mechanisms of selective (...) cross-breeding and cross-fertilization of parents of different species for the purpose of producing hybrid offspring. In addition to these processes, “hybridization ” also refers to natural and artificial processes of whole genome duplication that result in the doubling or trebling of the sets of chromosomes of the organism. This entry provides an overview of the impact of hybridity on agriculture. It begins with an historical sketch that traces the early horticulturalists’ and naturalists’ investigations of hybrids. This starts with the observations of Thomas Fairchild and Georges-Louis Leclerc, Comte de Buffon; and leads to the explanation of its mechanism by Gregor Mendel, James Watson and Francis Crick, and Ernst Mayr; and the eventual manipulation of hybrids and hybridization by Barbara McClintock. Following this, the reader is introduced to a number of key terms and concepts in use within current research as well as highlighting diverse ethical concerns that center on hybridization. Recent research that attempts to ascertain the role of hybridization in adaptive change will be introduced. This will include research on the evolution of crop species, increased biodiversity, and the use of hybrids to manipulate phenotypically desirable traits in agricultural crops. The focus of the discussion is on a particularly significant type of naturally occurring hybridization, polyploidy hybridization. Polyploids are organisms which have more than two complete genomes in each cell. This kind of hybridization is ubiquitous among crop plants. The role of polyploidy in plant evolution and the affects of polyploidy on plants and animals will be reviewed. A critical discussion of its agricultural value in the production of fertile polyploid hybrids highlights key epistemological, ontological, and ethical issues. These are illuminated with reference to the distinct processes of artificial and natural hybridization. A survey of these different kinds of hybridization includes the ethical and economic impacts of hybridity on global nutrition, the environment, and considerations of some practical implications for the agricultural industry. Tracking the role of hybrids, the process of hybridization, and the current impacts of it for agriculture requires knowledge of the history of its early conceptualization, understanding, and use. This is the topic of the following section. (shrink)
