The Biden administration has pledged to slash US greenhouse gas emissions by 50 to 52 per cent 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 US seeks to reclaim global leadership in the fight against global warming after former president Donald Trump withdrew it from international efforts to cut emissions.
It also marks an important milestone in Mr Biden’s broader plan to decarbonise the US 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.
Today I’m bringing together leaders from around the world to meet this moment of climate peril, and extraordinary opportunity. 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. https://t.co/lcUUsgyEo3

“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,” Mr Biden said in a tweet minutes before the summit began.
The new US target nearly doubles former President Barack Obama’s pledge of emissions cut 26 to 28 per cent below 2005 levels by 2025. Sector-specific goals will be laid out later this year.
How the US intends to reach its climate goals will be crucial to cementing US credibility on global warming, amid international concerns that America’s commitment to a clean energy economy can shift drastically from one administration to the next.

Mr Biden’s recently introduced $US2 trillion infrastructure plan contains numerous measures that could deliver some of the emissions cuts needed this decade, including a clean energy standard to achieve net-zero emissions in the power sector by 2035 and moves to electrify the vehicle fleet.
But the measures need to be passed by Congress before becoming reality.
Mr Biden focused on restoring US climate leadership during his campaign and in the first days of his presidency after Republican Donald Trump, a climate change sceptic, removed the US from the Paris agreement on global warming.
The new administration has come under heavy pressure from environmental groups, some corporate leaders, the UN secretary general and foreign governments to set a target to cut emissions by at least 50 per cent this decade to encourage other countries to set their own ambitious emissions goals.
Mr Biden will announce the number at the start of a climate summit on Thursday that will be attended by leaders from the world’s biggest emitters, including China.
World leaders aim to limit global warming to 1.5 degrees Celsius above pre-industrial levels, a threshold scientists say can prevent the worst impacts of climate change.
One of the administration officials said with the new US target, enhanced commitments from Japan and Canada, and prior targets from the European Union and Britain, countries accounting for more than half the world’s economy were now committed to reductions to achieve the 1.5 degrees Celsius goal.
“When we close this summit on Friday, we will unmistakably communicate … the US is back,” he said.
