The Costs of Reducing CO2 Emissions : A Comparison of Carbon Tax Curves with GREEN

This paper forms part of an OECD project which addresses the issue of the costs of reducing CO2 emissions by comparing the results from six global models of a set of standardised scenarios. This paper provides evidence of regional differences with respect to carbon tax curves through the middle of the next century. It also develops some analytical tools that can help to explain the main mechanisms at work in GREEN. Finally, it evaluates the welfare and output costs entailed in reduction emissions ...
