Congress Axes Biden-Era Protections That Shielded Alaskan Wetlands From Drilling

The U.S. House of Representatives voted Tuesday to strike down protections against oil drilling in some of the most diverse ecosystems and wildest lands left in North America. The resolution passed relatively quietly, but the bill will have an enormous impact on millions of acres in northern Alaska, the subject of a decades-long fight over conservation and drilling in the Arctic.

The vote overturns environmental protections put in place during the Biden administration, which shielded large swaths of Alaskan tundra from new oil and gas leasing. Alaska’s National Petroleum Reserve encompasses roughly 23 million acres of land in the north of the state, making it the largest block of public land in the United States. The passage Tuesday of Senate Joint Resolution 80 nullifies the Bureau of Land Management’s (BLM) 2022 rules governing the National Petroleum Reserve, which closed off roughly half of the reserve to oil and gas projects.  

Although the Biden-era rules still allowed for drilling in around 52 percent of the reserve, large swaths were saved for preservation. Those protected zones included key wildlife habitats, lands used by local communities and special areas like Teshekpuk Lake, one of the most diverse wetland ecosystems in the Arctic and a crucial area of passage for migratory bird populations. 

Arkansas Republican Rep. Bruce Westerman, who chairs the House Committee on Natural Resources, described the “resource-rich lands” in Alaska as “indispensable to unleashing American energy and mineral dominance” in a statement and celebrated the bill’s passage as a boon to Alaska’s economy, one that would “create jobs and promote access to affordable energy for years to come.” Westerman’s framing of the issue has been echoed by some Alaskan advocacy groups, including the Indigenous group Voice of the Arctic Inupiat, which expressed hopes that new drilling would boost tax revenue and improve state services. 

The change comes amid a wave of Republican-led efforts to reverse Biden-era constraints on fossil fuel production, part of a larger push under President Donald Trump to increase domestic drilling and scrap environmental guardrails that constrain the energy sector. Alaska is a key battleground for those efforts, with the Department of the Interior estimating that the National Petroleum Reserve holds up to 25 trillion cubic feet of natural gas and 8.7 billion barrels of oil that could be extracted. 

But environmental groups have been swift to point out there’s more than just fossil fuels in the nation’s largest federally managed land area. “This vote will authorize the fossil fuel industry’s continued destruction of habitat and landscapes that are critical for wildlife to survive,” Robert Dewey of the U.S. conservation group Defenders of Wildlife, said in a statement following the Senate vote.  

While Republican majorities pushed the measure through the Senate last month and on Tuesday through the House, a few Democrats also backed the environmental rollbacks. In the Senate, Pennsylvania Democrat John Fetterman voted with Republicans and on Tuesday, Texas Democrats Henry Cuellar and Vicente Gonzalez joined Jim Costa of California to vote in favor. President Trump is expected to sign the measure.

With the BLM’s 2022 protections erased, rules governing the reserve will revert to the 2020 plan adopted during Trump’s first term, which opened more than 80 percent of the lands to potential oil and gas leasing—including sensitive sections of the Teshekpuk Lake Special Area that had been off limits for decades.

Environmental groups warned in 2020 that the plan would punch roads and pipelines through delicate wetlands, disrupt migration routes for caribou and waterfowl and fragment habitats in complex, interconnected ecosystems in the Arctic. Those concerns drove the Biden administration to put in place stronger protections for special areas with environmental or cultural significance. Three years later, those safeguards are on the verge of being dismantled entirely. Under the reversion to the 2020 plan, roughly 82 percent of the reserve will again be open to new drilling.

The National Petroleum Reserve has historically been framed as a dormant bank stocked with fuel, set aside in 1923 as a strategic oil supply for the U.S. Navy. But in recent decades, scientists and Indigenous communities have highlighted the cultural and ecological importance of the region. Coastal lagoons that shelter whales and walruses abut Arctic tundra home to polar bear and caribou populations. These ecosystems sustain the subsistence hunting and fishing that many Indigenous communities have relied on for generations. 

The permafrost blanketing the reserve is also one of the world’s largest carbon stores. Oil development not only produces direct emissions from drilling in the ice, but can accelerate permafrost thaw, potentially releasing vast amounts of ancient carbon long locked in frozen tundra. Scientists warn that once released, that carbon cannot easily be recaptured.

The Biden administration in its approach to the reserve framed the areas as a globally significant climate refuge where oil and gas development needed to be tightly constrained. Tuesday’s vote is the latest signal that federal policy has shifted sharply away from those conservation principles and toward a landscape increasingly shaped by fossil fuel projects.
