How much greenhouse gas emission abatement is enough?

In a column at VoxEU.org Richard S.J. Tol, Research Professor at the Economic and Social Research Institute (Dublin) and the Professor of the Economics of Climate Change at the Vrije Universiteit Amsterdam, asks How much greenhouse gas emission abatement is enough?

Climate change will have widespread negative effects of uncertain magnitude. But this column argues that climate change is not humanity’s biggest challenge and needs to be solved without impeding economic development. It calls for a measured policy of greenhouse gas emission reduction.

While calling for a measured policy of greenhouse gas emission reductions Tol also says that there is reason to believe that European climate policy is overly ambitious while climate policy outside Europe is surely not ambitious enough.
