Within the Climate Action Tracker project, NewClimate Institute, Climate Analytics, PIK and Ecofys prepared an initial assessment of the recent announcements by the United States and China’s new pledges and proposals on emissions reductions for 2025 and 2030, in the context of the present international negotiations for a new climate agreement to be adopted at the end of 2015.

The announcement of increased ambition by the biggest emitters China and the United States one year ahead of the Paris Climate Summit in 2015 is a very important political development. It begins to close the gap between their previous pledges and the emissions limits needed to hold global warming below 2°C.

It is clear however that both could significantly improve over these new pledges. Adopting world best practice would enable substantial improvements, as outlined in the Climate Action Tracker’s update last month, where we looked at the potential for both countries.
