World far off track to meet climate goals: UN

The UN estimated Tuesday that nations’ carbon-cutting pledges imply a far-from-sufficient 10-percent emissions cut by 2035, cautioning that it was unable to provide a robust global overview after most countries failed to submit their plans on time. The estimate also incorporated a pledge by China, the world’s biggest polluter, to reduce emissions by 7-10 percent by 2035, its first absolute national target.
