President Joe Biden landed in Europe ahead of next week’s crucial UN climate summit, despite the fact that his flagship climate programme has yet to be approved by the US Congress.
More than $500 billion will be spent on green measures as part of President Obama’s $1.75 trillion (£1.2 trillion) Build Back Better social welfare programme.
Mr. Biden praised the measures as “historic” before leaving Washington.
However, divisions among Democrats make it doubtful that it will be passed before the meeting.
“It’s a framework that will create millions of jobs, grow the economy, invest in our nation and our people, turn the climate crisis into an opportunity, and put us on a path not just to compete, but to win the economic competition for the twenty-first century against China and every other major country in the world,” Vice President Joe Biden said in a White House television address.
Build Back Better includes additional financing for health and child care, education, and sustainable energy improvements, among other things.
Green spending would aim to reduce US greenhouse gas emissions considerably by 2030, provide new tax advantages for electric vehicles, and expand solar panel installation on American homes.
The president had intended to get the bill passed before the start of the global COP26 climate summit in Glasgow on Monday.
In Congress, the package is connected to a separate $1.2 trillion infrastructure bill.
The infrastructure bill cleared the Senate with an equal split, but some left-wing Democrats demand revisions to Build Back Better before agreeing to carry the infrastructure bill through the House of Representatives, insisting that both bills be voted on simultaneously. Mr. Biden’s Democratic colleagues scrapped plans for a vote on Thursday.
During a closed-door meeting on Capitol Hill, Mr. Biden pleaded with Democrats to support his legislative proposals, saying he wanted to show that US democracy still worked.
