Abstract

The approach to controlling greenhouse gas emissions suggested by simple neoclassical economic models has appeared in prominent mainstream journals. This entails weighing up the costs of control compared to the benefits of avoiding damages due to global climate change. This paper presents a critique of extending the microeconomic project based methodology to a complex global problem; raising issues of uncertainty and ignorance. An alternative to simple utilitarianism is seen to be necessary and the potential of a deontological approach is argued to be greater with regard to policy decisions concerning future generations.
