Abstract

This paper presents a framework to include feedbacks from climate impacts on the economy in integrated assessment models. The proposed framework uses a production function approach, which links climate impacts to key variables and parameters used in the specification of economic activity. The key endpoints within climate impact categories are linked to the relevant connections for a range of sectors in the economy. The paper pays particular attention to the challenges of distinguishing between damages and the costs of adapting to climate change. The paper also reviews existing studies and available data that can be used to establish linkages between climate impacts and key variables within economic models. There is considerable heterogeneity across the timing and geographic distribution of changes in climatic variables, the consequent changes in key physical and biogeochemical “endpoints” that might occur over time and space, and the magnitude of the resulting damages that these effects are likely to impose on the range of sectors in the economy. The review underlines the uncertainty involved in each of these dimensions and the research needs for the future. Le présent document expose une méthodologie visant à inclure, de façon systématique, les effets économiques consécutifs aux impacts du changement climatique dans les modèles d'évaluation intégrée. La méthode proposée se fonde sur le concept de la fonction de production, en reliant les différents impacts environnementaux associé au changement climatiques à leurs effets sur les variables et les paramètres clés des modèles utilisées pour décrire les mécanismes et interactions économiques. Il s’agit d’associer les principaux impacts environnementaux aux différentes activités économiques qu’ils sont appelés à impacter. Le document accorde une attention particulière à la difficulté de distinguer les coûts de l'adaptation au changement climatique des dégâts dus à ce changement. Le document passe également en revue les études existantes ainsi que les données disponibles qui peuvent être utilisées pour établir des liens entre les impacts climatiques et les variables clés dans les modèles économiques. Cette revue de littérature souligne les très fortes disparités spatiales et chronologiques des modifications environnementales dues au changement climatique, et par conséquent une forte hétérogénéité que ces impacts physiques et biogéochimiques sont susceptibles de poser à l'ensemble des secteurs de l'économie, tant dans leur amplitude que sur le plan géographique ou temporel. L’analyse souligne l'incertitude liée à chacune de ces dimensions et les besoins de la recherche pour l'avenir.
