English: This graph shows projected changes in annual human greenhouse gas (GHG) emissions between the years 2000 and 2100 for a range of climate change mitigation scenarios. Emissions are measured in billion tonnes of carbon dioxide-equivalent (GtCO2-eq).

Projections for 5 scenarios are shown. Each scenario is designed to stabilize atmospheric GHG concentrations at a different level: 450, 520, 670, 970 and 1390 ppmv. A summary table of the graph data is given in a later section. In the scenarios, global emissions peak then decline. Emissions peak sooner in the century for the lower stabilization scenarios.

These are the "A2r" mitigation scenarios. The global warming potentials used for the non-CO2 greenhouse gases are: 21 (CH4), 310 (N2O), 6500 (PFC), 23900 (SF6) and 1300 (HFC).
