Costs of Reducing CO2 Emissions: Evidence from Six Global Models

This paper summarises and analyses results of the OECD's Model Comparisons Project. The aim of the project is to better understand differences across six global models in the cost of reducing carbon dioxide emissions. In order to facilitate comparisons, key assumptions and reduction targets have been standardised. The paper provides evidence on; i) projected carbon dioxide emissions through the next century, and ii) the carbon taxes and output costs entailed in reducing these emissions ... Ce document resume et analyse les resultats du projet de l'OCDE de comparaison de modeles. Le but de ce projet est de mieux comprendre les differences de couts de reduction des emissions de dioxide de carbone que font apparaitre six modeles globaux. Pour faciliter ces comparaisons les hypotheses cles et les objectifs de reduction ont ete standardises. Cette etude met en evidence ; i) les emissions projetees de dioxyde de carbone d'ici a la fin du siecle prochain et ii) les taxes sur le carbone et les couts de production que suppose la reduction de ces emissions ...
