Indonesia, Poland, Vietnam and other nations pledged on Thursday to phase out use of coal-fired power and stop building plants, but their deal at the COP26 climate summit failed to win support from China, India and other top coal consumers.

Britain has said one of its main aims for the United Nations summit is "consigning coal power to history." The deal saw 23 nations making new commitments, a move the president of the COP26 summit, Alok Sharma, said put the end of coal "in sight."

"Today I think we can say that the end of coal is in sight," Sharma told the Glasgow meeting.
