Comments on Manne and Richels: "CO2 Emission Limits: An Economic Analysis for the USA"

This paper evaluates the Global 2100 model application on global warming by A. S. Manne and R G. Richels, which is presented in this edition of The Energy Journal The paper discusses Manne and Richels's general analytical framework, the Global 2100 model; and Manne and Richels's exploration of international interdependence, benefit calculations, and the uncertainty which must necessarily accrue to any discussion of global warming. The paper suggests that cost-benefit analyses, such as the one provided by Manne and Richels, are necessary for policy recommendations. Differences in regional impacts of global warming are noted. The paper concludes that Manne and Richels's study is very worthwhile and pleads for further studies.
