### Total emissions

#### Indicators:

- Emissions of CO2, CH4, N2O, CO, Black Carbon, Organic Carbon, NO2, NMVOC and SO2,

  This view summarizes the annual emissions of greenhouse gases, ozone precursors and acidifying compounds as they are simulated by different parts of IMAGE 2.4 (TIMER emisions model, land use emissions model and the terrestrial carbon model). These emissions are used within IMAGE 2.4 to compute the changing concentrations of the different gases in the atmosphere as simulated within the atmospheric chemistry model.

  #### Emissions of CO2, CH4, N2O, CO, Black Carbon, Organic Carbon, NO2, NMVOC and SO2 |
  units: CO2: Pg C/yr (Petagram carbon per year) CH4: Tg CH4/yr (Teragram CH4 per year) N2O: Tg N2O/yr (Teragram N per year) CO: Tg CO/yr (Teragram C per year) BC: Tg BC/yr (Teragram BC per year) OC: Tg OC/yr (Teragram OC per year) NO2: Tg N/yr (Teragram N per year) NMVOC: Tg NMVOC/yr (Teragram NMVOC per year) SO2: Tg S/yr (Teragram S per year) dimension: region, category |

  These variables show the overall emissions as they are simulated for four categories within different parts of IMAGE 2.4:

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