Applying the same percentages to the fair share mitigation of, for example, the United States and China, we can calculate their comparable mitigation efforts relative to their own Business-as-Usual baselines, and get 4.0 GtCo2e and 1.2 GtCO2e respectively. Translating these to the 1990 base year, this would mean for the United States that an “at least 41% below 1990” target would be an effort comparable to the EU’s “at least 40%” (since the United States typically utilizes 2005 as its base year, we can also translate this to “at least 50% below 2005”), while for China, a comparable effort would be to limit its emissions growth to “525% above 1990 levels”. For the Low Equity settings, the US’s effort would have to be “at least 15% below 1990” (or “at least 27% below 2005”) to be comparable to the EU’s INDC, while China would have to limit its emissions growth to “490% of 1990 levels.”[1] The same calculation for all remaining countries together (Rest of World) gives 3.2 and 5.8 GtCO2e using High and Low Equity settings, respectively
