GLASGOW (Reuters). President Joe Biden, on Monday, will assure the world that the United States can honor its commitment to cut greenhouse gas emissions by at least half by the year 2010. However, key policy to accomplish those reductions remains uncertain, according to his top climate aides.

Biden will meet with leaders from more than 100 countries at the COP26 climate conference in Glasgow. The start of the conference follows on from the G20 summit held in Rome, where a statement urged meaningful and effective action to combat climate change. But negotiators have a lot of work to do in order for COP26 to be able achieve its ambitious goals.

Gina McCarthy, National Climate Adviser, said Biden had committed to that goal. She did so through a crucial budget bill that would release $555billion in climate spending. Congress is still waiting for a vote on the bill after many months of defiant domestic negotiations.

“Here in Glasgow, he’s renewing the United States’ commitment to take swift and decisive action, including through his Build Back Better framework,” McCarthy told reporters.

“It is the biggest investment made in American history to fight the climate crisis. It will allow us to reduce our emissions by well over 1 gigaton, that is 1 billion metric tonnes in 2030.

Biden claimed on Sunday, that his Build Back better climate and social spending bills will be voted upon sometime this week. “God willing.”

Although the House of Representatives has yet not confirmed a date, they will vote on it.

McCarthy addressed the concerns surrounding Friday’s Supreme Court decision to review the authority of Environmental Protection Agency to regulate greenhouse gases emissions. This could potentially undermine U.S. climate goals.

McCarthy stated, “We are confident that the Supreme Court would confirm what they have before them. That is, EPA does not only have the right but also the authority and responsibility for keeping our communities and families safe from polluting.”

Biden will announce a long-term strategy on Monday that will outline how the U.S. can achieve its longer-term goal to net-zero emission by 2050. He will also say that he and Congress will collaborate to create a program of $3 billion in 2024 to help developing countries cope with the effects of climate change.
