It made the formal offer to the UN as a step towards a global deal in Paris in December. The EU has already promised to cut its emissions by a roughly similar proportion.

The announcement was made on Twitter with the words: "America is taking steps to #ActOnClimate, and the world is joining us" - accompanied by a picture of the President in China.
