The US has vowed to cut its planet-heating emissions by at least half by the end of the decade, in a ramping up of ambition aimed at rallying other countries to do more to confront the climate crisis.
Ahead of a virtual gathering of dozens of world leaders in a climate summit called by Joe Biden, which begins on Thursday, the White House said the US will aim to reduce its greenhouse gas emissions by between 50% and 52% by 2030, based on 2005 levels.
