Necessary Change in CO2 Emissions per GDP to Reach 1.5°C - 2.0°C Climate Change Limit in 2100

The necessary cumulative CO2 emissions reduction to reach the 1.5°C Global Warming limit in 2100 is 2,353,587 MtCO2. This may be done by decreasing the world’s CO2 emissions per GDP (Cp$) annually by 18%. The necessary cumulative CO2 emissions reduction to reach the 1.7°C Global Warming limit in 2100 is 2,086,161 MtCO2. This may be done by decreasing the world’s CO2 emissions per GDP (Cp$) annually by 9.34%. The necessary cumulative CO2 emissions reduction to reach the 2.0°C Global Warming limit in 2100 is 1,684,038 MtCO2. This may be done by decreasing the world’s CO2 emissions per GDP (Cp$) annually by 5.91%
