After the failure of the United Nations climate change conference at Copenhagen the EU is under domestic pressure to justify ambitious unilateral emissions reduction targets.

This paper examines a new strategy for evaluating whether the size of a new environmental regulation requires that benefit cost analyses consider general equilibrium effects. Size in the context refers to both the magnitude and distribution of cost increases across sectors and the benefits...

Energy models suggest that the cost of reducing carbon emissions from the transportation sector is high relative to other sectors, such as electricity generation. However, this paper shows that taxes to reduce passenger vehicle emissions produce large net benefits, rather than costs, when...
