US and China unveil climate goals

The US and China have unveiled ambitious targets to reduce greenhouse gases, aiming to inject fresh momentum into the global fight against climate change ahead of a make-or-break treaty to be finalised next year.

President Barack Obama announced that the US would move much faster in cutting pollution, with a goal to reduce by 26% to 28% by 2025, compared with 2005 levels. Earlier in his presidency, he had set a goal to cut emissions by 17% by 2020.
