The IMAGE climate model (based on MAGICC 6.0, [[CiteRef::IMG_Meinshausen_2011a]]) calculates atmospheric CO<sub>2</sub> concentration based on CO<sub>2</sub> emission data for energy, industry and land-use change; terrestrial carbon balance; and carbon uptake by the oceans (calculated in MAGICC on the basis of the Bern Ocean Carbon model).


Concentrations of other long-lived greenhouse gases (CH<sub>4</sub>, N<sub>2</sub>O, and halocarbons), and tropospheric ozone (O<sub>3</sub>) precursors (CO, NMVOC) are calculated by MAGICC in a simple atmospheric chemistry module. Halocarbons and N<sub>2</sub>O concentrations mostly show a simple mass-concentration conversion and half-life behaviour. CH<sub>4</sub> and ozone dynamics are more complex, with CH<sub>4</sub> lifetime depending on the OH concentration level, and O<sub>3</sub> and OH concentration levels depending on CH<sub>4</sub> concentrations, and NO<sub>X</sub>, CO and NMVOC emissions [[CiteRef::IMG_Meinshausen_2011b]].
==Emission abatement==
 
Emissions from energy, industry, agriculture, waste and land-use sources are also expected to vary in future years, as a result of climate policy. This is described using abatement coefficients, the values of which depend on the scenario assumptions and the stringency of climate policy described in the climate policy component. In scenarios with climate change or sustainability as the key feature in the storyline, abatement is more important than in business-as-usual scenarios. Abatement factors are used for CH<sub>4</sub> emissions from fossil fuel production and transport, N<sub>2</sub>O emissions from transport, CH<sub>4</sub> emissions from enteric fermentation and animal waste, and N<sub>2</sub>O emissions from animal waste according to the IPCC method. These abatement files are calculated in the IMAGE climate policy sub-model FAIR by comparing the costs of non-CO<sub>2</sub> abatement in agriculture and other mitigation options.

Emission abatement

Emissions from energy, industry, agriculture, waste and land-use sources are also expected to vary in future years, as a result of climate policy. This is described using abatement coefficients, the values of which depend on the scenario assumptions and the stringency of climate policy described in the climate policy component. In scenarios with climate change or sustainability as the key feature in the storyline, abatement is more important than in business-as-usual scenarios. Abatement factors are used for CH4 emissions from fossil fuel production and transport, N2O emissions from transport, CH4 emissions from enteric fermentation and animal waste, and N2O emissions from animal waste according to the IPCC method. These abatement files are calculated in the IMAGE climate policy sub-model FAIR by comparing the costs of non-CO2 abatement in agriculture and other mitigation options.
