This article explores the consequences of falling costs of solar and wind power for the ethics of climate change mitigation. We suggest that price competitiveness of renewables reveals a divergence of interest between fossil fuel consumers and producers: cheap renewables strengthen precautionary arguments for aggressive mitigation for consumers but threaten the economic base of producers. As existing applications of the precautionary principle to climate change do not address this issue, we develop a novel approach based on lexical utilities. Given the (...) premise that climate catastrophe entails economic catastrophe but not vice versa, we argue that both producers and consumers should favor mitigation. (shrink)

According to some scholars, while sets of greenhouse gases emissions generate harms deriving from climate change, which can be mitigated through collective actions, individual emissions and mitigation activities seem to be causally insufficient to cause harms. If so, single individuals are neither responsible for climate harms, nor they have mitigation duties. If this view were true, there would be collective responsibility for climate harms without individual responsibility and collective mitigation duties without individual duties: this is puzzling. This paper explores a (...) way to solve this puzzle. First, it will be argued that individual emissions, though not proper and full-fledged causes, causally contribute to raise the probability of climate harms. As a consequence, individuals are in fact responsible for their expected contributions to climate harms – this is contributive responsibility for likely outcomes. Second, it will be argued that people have responsibility also for the possible impacts of their individual emissions on climate harms. People can plausibly be regarded as individually responsible for the possible outcomes of their actions in close possible alternative worlds – this is robust responsibility. Non-causal individual responsibility for climate harms is plausible, and the puzzle may be solved. (shrink)

Utilitarians must think collectively about the future because many contemporary moral issues require collective responses to avoid possible future harms. But current rule utilitarianism does not accommodate the distant future. Drawing on my recent books Future People and Ethics for a Broken World, I defend a new utilitarianism whose central ethical question is: What moral code should we teach the next generation? This new theory honours utilitarianism’s past and provides the flexibility to adapt to the full range of credible futures (...) – from futures broken by climate change to the digital, virtual and predictable futures produced by various possible technologies.

We need an account of corporate agency that is temporally robust – one that will help future people to cope with challenges posed by corporate groups in a range of credible futures. In particular, we need to bequeath moral resources that enable future people to avoid futures dominated by corporate groups that have no regard for human beings. This paper asks how future philosophers living in broken or digital futures might re-imagine contemporary debates about corporate agency. It argues that the (...) only temporally robust account is moralised extreme collectivism, where full moral personhood is accorded to those corporate groups that are reliably disposed to respond appropriately to moral reasons.
