The Biden administration on Thursday pledged to slash U.S. greenhouse gas emissions by 50%-52% from 2005 levels by 2030, a new target it hopes will spur other big emitter countries to raise their ambition to combat climate change.
The goal, unveiled at the start of a two-day climate summit hosted by Democratic President Joe Biden, comes as the United States seeks to reclaim global leadership in the fight against global warming after former President Donald Trump withdrew the country from international efforts to cut emissions.
It also marks an important milestone in Biden's broader plan to decarbonize the U.S. economy entirely by 2050 - an agenda he says can create millions of good-paying jobs but which many Republicans say they fear will damage the economy.
The emissions cuts are expected to come from power plants, automobiles, and other sectors across the economy, but the White House did not set individual targets for those industries.
"No nation can solve this crisis on its own, and this summit is a step on a path to a secure, prosperous, and sustainable future," Biden said in a tweet minutes before the summit began.
