US to ban oil drilling in Arctic Ocean

U.S. President Joe Biden's administration has announced new steps to ban oil and gas drilling in the Arctic Ocean and limit onshore drilling in Alaska, to protect whales, seals, polar bears, grizzly bears and caribou.

The announcement on Sunday comes as Biden is expected to approve ConocoPhillips' massive Willow oil project, fiercely opposed by environmentalists, in northwest Alaska.

Biden will make nearly 1.2 million hectares of the Beaufort Sea in the Arctic Ocean "indefinitely off limits" for oil and gas leasing, building on an Obama-era ban and effectively closing off U.S. Arctic waters to oil exploration.

In addition to the drilling ban, the government will put forward new protections for more than 5.3 million hectares of "ecologically sensitive" Special Areas within Alaska's petroleum reserve, the administration said in a statement on Sunday.

The area includes the Teshekpuk Lake, Utukok Uplands, Colville River, Kasegaluk Lagoon and Peard Bay Special Areas.

The plan comes as Biden tries to balance his goals of decarbonising the U.S. economy with calls to increase domestic fuel supply to keep prices low.

The Willow project would be located inside the National Petroleum Reserve-Alaska, a 9.3 million-hectare area on the state's North Slope that is the largest tract of undisturbed public land in the United States.

An environmental group said the new protections announced on Sunday did not go far enough and the government should stop oil and gas developments to help fight climate change.

"It's insulting that Biden thinks this will change our minds about the Willow project," said Kristen Monsell, a senior attorney at the Center for Biological Diversity.

"Protecting one area of the Arctic so you can destroy another doesn't make sense, and it won't help the people and wildlife who will be upended by the Willow project," she said.

On Friday, the White House pushed back on reports that Biden will authorise the project as soon as this week, saying a decision had not been made yet, but a source familiar with the matter has said the decision could be made as early as Monday.
