Efficiency and future
Economics and Philosophy, 34 (2018), pp. 221–41.
Standard lessons from economics tell us that an externality creates inefficiency, and that this inefficiency can be removed by internalizing the externality. This paper considers how successfully these lessons can be extended to intergenerational externalities such as emissions of greenhouse gas. For intergenerational externalities, the standard lessons involve comparisons between states whose populations of people differ, either in their identities or their numbers. Common notions of efficiency break down in these comparisons. This paper supplies a new notion of efficiency that allows the lessons to survive, but at the cost of reducing their practical significance.

Written with Duncan Foley
Because greenhouse gas is an externality, it creates Pareto inefficiency. It is therefore possible to respond to climate change in a way that is a Pareeto improvement, requiring no sacrifice from anyone in any generation. A great deal of benefit can be achieved by doing so. However, making a Pareto improvement in practice requires a new international financial institution. We need a World Climate Bank, which will allow investments to reduce greenhouse gas emissions to be financed by public debt.
Do not ask for morality
In The Ethical Underpinnings of Climate Economics, edited by Adrian Walsh, Säde Hormio and Duncan Purves, Routledge, 2016, pp. 9-21.
Experience has shown that governments cannot be motivated by morality to make sufficient investments to bring climate change under control. They therefore must be motivated by self interest. It is possible to respond adequately to climate change without asking for a sacrifice from anyone in any generation.
A reply to my critics
Midwest Studies in Philosophy, 40 (2016), pp. 158-171
A response to three comments on my Climate Matters. In responding to Elizabeth Cripps, I argue that each individual’s emissions do harm because the harm done by cumulative emissions is roughly proportional to their quantity. Each rich person’s emissions are therefore an injustice. In responding to Holly Lawford-Smith, I point out that the harm done by each tonne of a person’s emissions is very much greater than the cost to the person of avoiding that emission, so very few among the rich have any excuse for making emissions. In response to Paul Bou-Habib, I argue that the morality of climate change has no need for a ‘person-affecting’ notion of improvement, and that notion is in any case defective because it can be cyclical.
