What is the Economics of Climate Change

�Greenhouse gas (GHG) emissions are exter nalities and represent the biggest market failure the world has seen. We all produce emissions, people around the world are already suffering from past emissions, and current emissions will have potentially catastrophic impacts in the future. Thus, these emissions are not ordinary, localized externalities. Risk on a global scale is at the core of the issue. These basic features of the problem must shape the economic analy sis we bring to bear; failure to do this will, and has, produced approaches to policy that are pro foundly misleading and indeed dangerous. The purpose of this lecture is to set out what I think is an appropriate way to examine the economics of climate change, given the unique scientific and economic challenges posed, and to suggest implications for emissions targets, policy instruments, and global action. The sub ject is complex and very wide-ranging. It is a subject of vital importance but one in which the economics is fairly young. A central challenge is to provide the economic tools necessary as
