President Joe Biden will move Monday to block all future oil and gas drilling across more than 625 million acres of federal waters — equivalent to nearly a quarter of the total land area of the United States, according to two people briefed on the decision who spoke on the condition of anonymity because the announcement is not yet public.

The action underscores how Biden is racing to cement his legacy on climate change and conservation in his last weeks in office. President-elect Donald Trump, who has described his energy policy as “drill, baby, drill,” is likely to work with congressional Republicans to challenge the decision.

Biden will issue two memorandums that prohibit future federal oil and gas leasing across large swaths of the Atlantic Ocean, the Pacific Ocean, the eastern Gulf of Mexico and the Northern Bering Sea in Alaska, the two people said. The oil and gas industry has long prized the eastern Gulf of Mexico in particular, viewing the area as a key part of its offshore production plans.

Karoline Leavitt, a spokeswoman for the Trump transition team, said in an email: “This is a disgraceful decision designed to exact political revenge on the American people who gave President Trump a mandate to increase drilling and lower gas prices. Rest assured, Joe Biden will fail, and we will drill, baby, drill.”

The move could have the biggest impact in the Gulf of Mexico, which accounts for about 14 percent of the country’s crude oil production, according to the U.S. Energy Information Administration. Industry operations there focus on a small sliver of federal waters off Louisiana’s coast.
