The Biden administration on Wednesday will auction oil drilling rights to 80 million acres in the U.S. Gulf of Mexico days after joining a global agreement that for the first time targeted fossil fuels as the main driver of global warming.

The sale by the Department of Interior will be the first under President Joe Biden, whose administration paused drilling sales under a promise to end development on federal properties. But Biden lost a court fight to oil-producing states that sued to reinstate the sales.

The administration has appealed and a suit by environmental groups seeking to halt the sale is pending. The U.S. is moving ahead to hold onshore lease auctions in several states early next year.

Interior’s Bureau of Ocean Energy Management will auction almost all available unleased Gulf of Mexico blocks, 80 million acres, at a live-streamed event on Wednesday morning.

It will be the first opportunity to test the oil and gas industry’s demand for Gulf acreage with energy prices at multi-year highs. U.S. crude futures on Tuesday settled at $80.76 a barrel, up 95% in the last 12 months.

The Trump administration’s final Gulf sale, held last November, generated a modest $121 million in high bids. But oil companies Royal Dutch Shell, BP and Chevron are seizing on the higher prices to advance offshore projects.
