This tool is included in the Development Impacts Assessment (DIA) Toolkit from the LEDS Global Partnership.


The MIT IGSM is designed to evaluate the effects of climate change and related mitigation efforts, for example, the effectiveness and cost of specific climate change mitigation policies, the advantages and risks of waiting for better scientific understanding of climate change, and the regions and economic sectors most likely to be affected.
