What’s your emissions quota?


Figure 2 | Quotas, cumulative committed emissions and fossil-fuel reserves. Past cumulative fossil-fuel CO2 emissions (purple), future committed
emissions (orange) and available fossil-fuel carbon quotas to meet warming limits of 2, 2.5 and 3 °C with 50% probability (green), for 10 regions and
the world, under inertia, blended and equity sharing principles. Stacked bars are cumulative; numbers give the contribution of each increment in Gt CO2.
Negative increments are shown below the zero axis. Also shown are fossil-fuel reserves (coal, oil, gas, unconventional oil, unconventional gas).
