Navy Secretary John Phelan said he’s rescinding a Navy plan focused on combating climate change established by the Biden administration.

“Today, I’m focusing on warfighters first and I’m rescinding the Biden administration’s climate action program,” he said in a video posted to X on Tuesday. “Our focus needs to be on lethality and our warfighters.”

That plan was spearheaded by Meredith Berger, formerly the senior Navy civilian overseeing energy, installations and environment, during the Biden administration in 2022.

“2030 is the marker that we laid down initially because the scientific community and others have said that this is the decade of decisive action and so we’re taking that very seriously,” she told reporters at the time. Defense Department officials had specifically expressed concern that the Marine Corps’s famous East Coast training grounds, Parris Island in South Carolina, could be largely underwater by 2099.
