President Joe Biden will announce Thursday that the United States intends to cut planet-warming emissions nearly in half by the end of the decade, a target that would require Americans to transform the way they drive, heat their homes and manufacture goods.

The target, confirmed by three people briefed on the plan, is timed to a closely watched global summit meeting that Biden is hosting Thursday and Friday, which is aimed at sending a message that the United States is rejoining international efforts to fight global warming after four years of climate denial from the Trump administration.

A White House spokesperson declined to comment on the U.S. target, which was first reported by The Washington Post.
