Carbon pricing is one of the most politically important approaches for the mitigation of climate change in the world today. Most political actors who are not committed to climate change denial favor carbon pricing, either as emissions trading or carbon taxation. In this article, I argue that carbon pricing should be considered unfair in most of its forms. I present a line of criticism called the Unfair Burdens Argument. It states that the most politically relevant ways to price carbon needlessly (...) burden the less affluent more than the more affluent. This is unfair because, among other things, the more affluent have on average done more to create the problem of climate change in the first place. Principles for the fair distribution of burdens under climate change mitigation like the Polluter Pays Principle, which were thought to support carbon pricing, turn out to speak against it, when interpreted properly. Although the Unfair Burdens Argument on its own cannot show that carbon pricing is impermissible, it offers important clues for what a morally permissible form of climate change mitigation would look like.

What is the practical relevance of the Non-Identity Problem (NIP) for our climate change-related duties? Climate change and the NIP are often discussed together, but there is surprisingly little work on the practical relevance of the NIP for the ethics of climate change. The central claim of this article is that the NIP makes a relatively minor difference to our climate change-related duties even if we pursue what has become known as the ‘bite the bullet’ strategy: endorse a person-affecting view (...) threatened by the NIP and not modify it in such a way as to evade the NIP. In particular I will argue that a harm-based view can justify the big-picture call for action emerging from the field of climate ethics. The key to reaching this conclusion is pointing out the consequences of our climate change-related decisions for people whose existence does not depend on these very decisions. (shrink)

The extent of our duties to mitigate climate change is commonly conceptualized in terms of temperature goals like the 1.5°C and the 2°C target and corresponding emissions budgets. While I do acknowledge the political advantages of any framework that is relatively easy to understand, I argue that this particular framework does not capture the true extent of our mitigation duties. Instead I argue for a more differentiated approach that is based on the well-known distinction between subsistence and luxury emissions. At (...) the heart of this approach lies the argument that we have no budget of substantial, net-positive luxury emissions left. In a world in which dangerous climate change has begun, we must expect all further substantial, net-positive luxury emissions to cause harm. Since they lack the kind of justification needed for them to be nevertheless permissible, I conclude that we must stop emitting them with immediate effect. I also briefly discuss the difficult case of subsistence emissions and offer some first thoughts on the morality of a third category of emissions, what I call ‘transition emissions’. (shrink)

Der Utilitarismus ist eine der einflussreichsten Moraltheorien in der Geschichte der westlichen Philosophie und wurde historisch von Autoren wie Jeremy Bentham, John Stuart Mill und Henry Sidgwick entscheidend geprägt. Er gehört zu den konsequentialistischen Moraltheorien; bewertet die Moralität von Handlungen also ausschließlich über deren Folgen und den Vergleich zu den Folgen anderer möglicher Handlungsoptionen. Allgemein gesprochen besagt der Utilitarismus, dass unser Handeln darauf zielen sollte, den Gesamtnutzen zu maximieren. Diese Forderung wird von verschiedenen Varianten des Utilitarismus unterschiedlich konkretisiert.

Es gibt kaum Veröffentlichungen, die sich explizit mit der Relevanz des Klimawandels für Menschenbilder beschäftigen, aber es gibt eine Vielzahl von Debatten rund um den Klimawandel, die wichtige Anknüpfungspunkte zum Themenkomplex Menschenbilder beinhalten. Fünf dieser Diskussionen werden im Folgenden aufgegriffen und in ihrer Relevanz erläutert. Im Hinblick auf Menschenbilder berührt der Klimawandel insbesondere Fragen nach der Stellung des Menschen im Kosmos, nach zentralen menschliche Verhaltensfaktoren und nach dem guten bzw. sinnvollen menschlichen Leben.

Producing food on a large scale without killing any animals seems currently impossible. This poses a challenge for deontological positions that involve a prohibition against killing sentient creatures: it seems that according to these positions omnivorous, vegetarian and vegan diets all rely on food produced in impermissible ways. In order to meet this challenge, deontologists might introduce consequentialist considerations into their theories, for example some principles that effectively require to kill as few animals as possible. This is the kind of (...) strategy Tom Regan has pursued. However, we argue that the challenge for deontological positions on the ethics of food production can also be met by invoking a prominent deontological principle. The doctrine of double effect, with its distinction between bringing about harm intentionally and bringing about harm as a merely foreseen consequence of one’s action, enables us to see a morally significant difference between the various ways to produce food other than the number of animals killed. In this paper we will review some of these ways using Warren S. Quinn’s version of the DDE and show that a more thoroughgoing deontological ethics of food production than Regan’s classic theory is possible. We thereby present a novel way of evaluating modes of food production. (shrink)
