### Cumulative anthropogenic emissions

#### Indicators:

Cumulative anthropogenic emissions of CO2, CH4 and N2O since 1970

The indicators presented provide a summary of greenhouse gas emissions as they are accumulated from simulations by different parts of IMAGE 2.4 (TIMER energy-industry emissions model, land-use emissions model and terrestrial carbon model). The total emissions, as applied in the atmospheric chemistry model to simulate the built-up of the different gases in the atmosphere, are accumulated from 1970 onwards. Cumulative emissions of CO2, CH4, N2O and the CO2 equivalent emissions, can be visualized.

| #### Cumulative anthropogenic emissions of CO2, CH4 and N2O since 1970
| unit:Pg C (Petagram C for CO2), Tg CH4 (Teragram for CH4) and Tg N (Teragram N for N2O) dimension: region, category

These variables show the overall cumulative emissions since 1970 as simulated for four source categories in different parts of IMAGE 2.4:

1. Emissions from energy use;
2. Emissions from industrial production;
3. Emissions from land use and natural sources;
