This paper develops and operationalizes the Integrated Economic-Environmental Modelling (IEEM) platform which integrates environmental data organized under the first international standard for environmental-economic accounting with a powerful economy-wide modelling approach. IEEM enables the ex-ante economic analysis of public policies and investment on the economy and the environment in a quantitative, comprehensive and consistent framework.

This paper responds to the request of G20 Finance Ministers in exploring scaled up finance for climate change adaptation and mitigation in developing countries. In so doing it builds upon and extends the work of last year‘s U.N. Secretary-General‘s High Level Advisory Group on Climate Change Financing (AGF). Its starting point is the commitment made in the Copenhagen Accord and Cancun Agreements on the part of developed countries to provide new and additional resources for climate change activities in developing countries.
