GHGs - AIM-Hub

|Solution concept||General equilibrium (closed economy)|
AIM/CGE simulates emissions from long-lived GHGs (CO2, CH4, N2O, F-gases, Montreal Protocol gases, HFCs). 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 difference of land use from previous year). Other CO2 emissions, CH4, and N2O emissions are basically associated with each sector's activity level. Emissions of the other gases are calculated based on constant income elasticity.
Reduction in energy-related emissions is associated with detailed technological options, which provide both improved energy efficiency and a carbon factor reduction. The CO2 resulting from land-use changes is reduced under the scenario including the pricing of carbon stock. Other reduction measures for the non-CO2 emissions use models based on the marginal abatement cost (MAC) curve with an exponential function.
