Historical and projected total GHG emissions according to NDCs

The universal Paris Agreement (PA) of 2015 is a historic landmark in global efforts to combat climate change. The USA and the EU both received praise for their combined climate diplomacy efforts that allowed the treaty to be signed. Signatories committed to keep global warming well below 2°C and to make efforts to prevent it from rising above 1.5°C. As established in SR1.5, emissions should decline 45 % or 25 % by 2030, compared to 2010, to reach respectively the 1.5°C or 2°C goal. However, new or updated nationally determined contributions (NDC), due at the end of 2020, were only received from 40 % of signatories, with key economies, including China and the USA missing. The initial analysis showed overall commitments as too low and a risk of exceeding warming targets.
