Asia-Pacific Integrated Model (AIM)

From Open Energy Information

AIM is a large-scale computer simulation model for assessing policy options to stabilize the global climate through greenhouse gas emissions reduction, with an emphasis on the Asia-Pacific region.

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


AIM comprises three main models: a greenhouse gas emissions model (AIM/Emission); a global climate change model (AIM/Climate); and a climate change impact model (AIM/Impact). The AIM/Emission model includes data and information on population, economic trends, and government policies, and estimates energy consumption, land use changes, and greenhouse gas emissions. The AIM/Climate model examines the outcome of different policy scenarios. The AIM/Impact model estimates impacts of the various scenarios on primary production industries and human health.
