C3IAM simulates long-lived GHG emissions of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). CO2 emissions from fuel combustion are calculated based on energy sources with fixed coefficient. CO2 resulting from land-use changes is endogenously calculated as a consequence of the land use (taking changes of land use from previous year). CO2 emissions from industrial process, CH4 and N2O emissions are basically associated with each sector’s activity level. The activity level and corresponding emissions in the base year are drawn from the Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS)[1].
