Asia-Pacific Integrated Model (AIM)

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

AIM is comprised of three main models:

  • the GHG emission model,
  • the global climate change model,
  • the climate change impact model.

The emission model estimates GHG emissions and assesses policy options to reduce them. The climate model forecasts concentrations of GHG in the atmosphere and estimates the global mean temperature increase. The impact model estimates climate change impacts on natural environment and socio-economy of the Asian-Pacific region.

The research program has made major contributions to policy deliberations at the nations, regional and global levels. The AIM model has been used to provide global and regional emission scenarios and regional impact assessments to the IPCC. The AIM model has been evaluated at the Stanford Energy Modeling Forum for the international comparison of emission scenarios and impact assessments.

Key questions addressed:

  • What impact will a given policy have on GHG emissions?
  • How will projected GHG emissions impact the gloabl mean temperature?
  • How will climate change impact the environment and economy of the Asia-Pacific region?

Sample data inputs:

  • Energy consumption
  • Gross domestic product
  • Number of households

Sample quantitative outputs:

  • Emissions estimates (CO2, SO2, NOx)
  • Total primary energy supply
  • Electricity generation by fuel-type
  • Sector-wide energy consumption
  • Gross domestic product
