COP28 lines up new climate pledges - but do they work?
While the world's climate diplomats huddle over draft decisions to be made at the end of this year's U.N. climate summit, governments at COP28 are firing off a flurry of new promises for action. Among the expected pledges at COP28 are a goal to triple renewable energy capacity and initiatives on methane and coal power. Unlike official summit decisions, which must be passed by consensus among the nearly 200 countries, voluntary pledges can be made quickly, and boldly, without the worry of one party objecting.
