The new president is unwinding Trump’s climate change legacy while forging his own.

President Biden placed climate change squarely at the center of his White House agenda on Wednesday, using his first hours in office to rejoin the Paris climate accord and begin overturning more than 100 environmental actions taken by the Trump administration.

Administration officials are suggesting that they will go well beyond reversing Trump’s policies. On Thursday U.S. presidential climate envoy John F. Kerry said the U.S. and other nations must commit to much deeper carbon cuts to avert dire climate impacts, and the Interior Department issued an order requiring signoff from a top political appointee for any new oil and gas lease or drilling activity. The directive, which could slow approval for more than 400 drilling permit applications, prompted an immediate outcry from the oil and gas industry.

Those initial moves are the first in what promises to be a much longer — and more arduous — effort to unwind the Trump administration’s sweeping environmental and energy policies, which were marked by aggressive deregulation, prioritizing the fossil fuels industry and sidelining efforts to combat climate change or protect imperiled animals.

Trump worked to scale back or abolish more than 200 environmental protections in just a single term, according to a Washington Post analysis, completing more than 170 of them. Biden can overturn some of them with a stroke of a pen. Others will take years to undo, and some may never be reversed. Four Obama-era regulations were nullified under the Congressional Review Act, which prevents the introduction of a new rule that is “substantially the same” as what had been replaced, making Trump’s actions particularly hard to reverse.

The majority of Trump’s rollbacks affect air pollution and greenhouse gas emissions linked to climate change, though 27 affect wildlife and 23 relate to infrastructure and planning. Though Biden is unlikely to target every one of his predecessor’s environmental actions, dozens of them are already in his sights.

Air pollution and greenhouse gases

Status of Trump’s rollbacks: 1 overturned 22 targeted 41 not yet targeted

The Trump administration enacted at least 64 policies weakening or overturning regulations aimed at curbing air pollution and greenhouse gas emissions fueling global warming. Biden has vowed to reverse that legacy and promote a low-carbon future instead. By signing a document to rejoin the Paris climate agreement on his first day in office, the new president reversed one of his predecessor’s signature policies and signaled a different path.

One of the hallmarks of outgoing Interior Secretary David Bernhardt’s legacy has been the narrowing of safeguards for endangered wildlife. The northern spotted owl, whose forest habitat is disappearing; the Pacific walrus, which faces shrinking sea ice; and the Bryde’s whale, threatened by oil and gas drilling in the Gulf of Mexico, are likely to receive enhanced protections under Biden.
