The Trump administration is pursuing one of the most aggressive oil and gas expansion programs in decades, targeting federal lands across America. The scale is substantial: over 200 million acres of Bureau of Land Management (BLM) lands in the West—representing 81 percent of all BLM lands—are already open to oil and gas leasing. But the administration’s actual expansion goes far beyond what was previously available. In 2025 alone, Trump’s Department of Interior approved 6,027 new oil and gas permits, the most issued in 15 years, and leased 328,000 acres across 369 parcels in 10 states, generating $356.6 million in revenue.
The acreage figures are staggering when you look at the specific proposals. California faces the most dramatic expansion: the administration proposed opening over 1 million acres of public lands and mineral rights to oil and gas drilling and fracking, including approximately 850,000 acres in Central California that includes public lands and beaches. Meanwhile, in Alaska, the administration has already secured 1.3 million acres won by oil companies for Arctic drilling and is considering reopening 13 million additional acres of intact landscapes in the Arctic. Offshore, the administration revoked Biden-era drilling restrictions on 625 million acres of federal ocean waters and is proposing 1.27 billion acres for federal offshore lease sales, including California’s offshore areas for the first time since 1984.

How Much Federal Land Is Currently Available for Oil and Gas Development?
The foundation for this expansion already exists. As of January 2025, the trump administration inherited a landscape where the vast majority of western public lands were legally available for oil and gas leasing: 200 million acres, or 81 percent of all BLM lands in the West. Additionally, 21.3 million acres of BLM lands are currently under active lease for oil and gas development and production, meaning companies already have legal rights to drill on these parcels. These figures are crucial context for understanding the expansion—the administration is not opening entirely new lands to drilling from scratch but rather accelerating leasing, permitting, and development on lands that were already designated for potential oil and gas use. The existing lease base is geographically diverse.
Oil and gas leases span across ten states, from New Mexico and Colorado to Montana and Wyoming. The 328,000 acres leased through 22 BLM lease sales between January and December 2025 demonstrates that the administration is actively moving parcels from “available for leasing” to “actively leased.” Each lease sale represents a completed transaction where energy companies have won competitive bids for drilling rights. This matters because once land is leased, the legal path to development becomes shorter and more certain. However, availability does not guarantee development. Many leased acres remain undeveloped, sometimes for decades. A parcel can be under lease for oil and gas exploration but never have an oil rig drilled on it due to market conditions, technical challenges, or permitting hurdles. The distinction between acreage “available for leasing,” “leased,” and “actively being developed” represents three different stages in the drilling pipeline, and the Trump administration is attempting to accelerate movement through all three.
The Scope of California’s Oil and Gas Expansion Proposal
California’s proposed expansion represents the most immediate and geographically concentrated element of Trump’s drilling agenda. The administration has proposed opening 850,000 acres in Central California—comprising roughly 400,000 acres of public lands and beaches plus surrounding areas—to drilling and fracking. Beyond that, the broader proposal targets 1 million acres of California public lands and mineral rights for oil and gas expansion. For context, California’s Central Coast has historically been one of the nation’s most oil-rich but also most environmentally sensitive regions, with pristine coastlines, agricultural land, and protected ecosystems. What makes this expansion particularly significant is the reversal of recent policy. California has spent the last two decades implementing increasingly stringent regulations on new oil development.
The state banned new oil leases on state lands in 2018 and has worked to limit federal drilling in state waters. The Trump administration’s proposal directly contradicts this trajectory. The 850,000-acre proposal includes land near Big Sur, one of America’s most iconic coastlines, and extends into agricultural areas of the Central Valley. If implemented, these would be the first federal offshore lease sales in California waters since 1984. The limitation here is practical: not all proposed land will necessarily be developed even if made available. Market conditions, technical drilling challenges, and potential legal challenges from environmental and state groups could slow or stop actual drilling operations. The proposal to lease acreage is not the same as the certainty that oil rigs will appear on the landscape, though the Trump administration is clearly removing regulatory barriers that would otherwise prevent such development.
Alaska’s Vast Arctic Oil Frontier
Alaska represents a different category of expansion—one that targets some of the most pristine and largest remaining intact landscapes in America. The administration has already secured 1.3 million acres in the Alaskan Arctic won by oil companies for drilling. This followed earlier actions that reopened the Arctic National Wildlife Refuge (ANWR) and the National Petroleum Reserve in Alaska (NPR-A)—respectively 19 million and 23 million acres—for oil and gas leases. Beyond what has been secured, an additional 13 million acres of intact Alaskan landscapes could be opened to oil and gas leasing if the Western Arctic Special Areas Rule is reversed. The scale of Alaska’s potential is dramatic compared to the lower 48 states.
The National Petroleum Reserve in Alaska alone covers an area larger than the entire state of Maine. The Arctic National Wildlife Refuge, despite its protected status as a wildlife refuge, was opened to drilling as part of the 2017 tax bill and remains available for leasing. These regions were historically off-limits to oil companies precisely because of their environmental sensitivity and because they are home to migratory caribou herds, subsistence hunting grounds for Alaska Native communities, and some of the continent’s most intact ecosystems. A key warning: Arctic oil development has unique costs and risks. Drilling in Alaska’s Arctic requires massive infrastructure investment, faces extreme weather and logistical challenges, and any spill or environmental damage occurs in an ecosystem where cleanup is nearly impossible during winter months. The Trump administration is proposing to open these lands, but whether companies will actually develop them depends on global oil prices, technological feasibility, and the administration’s ability to overcome potential legal challenges from conservation groups and Alaska Native communities who depend on these lands for subsistence hunting.
The Offshore Oil Frontier: Federal Waters and California
The Trump administration’s offshore drilling agenda represents a different frontier entirely—federal ocean waters that Biden-era restrictions had largely protected from new development. The administration revoked Biden-era drilling restrictions affecting 625 million acres of federal waters. More aggressively, it is proposing 1.27 billion acres for offshore oil and gas auctioning. This includes California’s offshore areas, which would see six lease sales planned for 2027-2030—the first federal leasing off California’s coast in over four decades. The offshore proposal is geographically expansive: it includes lease sales in the Eastern Gulf of Mexico scheduled for 2029-2030, and over twenty lease sales in Alaska’s offshore waters through 2031. Alaska’s offshore areas represent some of the most pristine and biologically productive waters in America, with critical fisheries and marine mammal populations.
California’s offshore waters have been protected from federal leasing since 1984, and the return of federal lease sales there represents a major shift in energy policy. For comparison, in the lower 48 states, the majority of recent offshore development has concentrated in the Gulf of Mexico, which has established infrastructure and decades of development experience. The tradeoff is significant: offshore drilling carries spill risks that onshore drilling does not. The Deepwater Horizon disaster in 2010 killed eleven workers and spilled nearly 5 million barrels of oil into the Gulf of Mexico, resulting in one of the largest environmental disasters in U.S. history. While safety equipment and regulations have improved since then, the risk remains. The Trump administration’s offshore expansion would dramatically increase the number of active platforms in federal waters, proportionally increasing the statistical likelihood of accidents or spills.
The Permitting Acceleration and Its Environmental Tradeoffs
Beyond opening new land and water to leasing, the Trump administration has dramatically accelerated the permitting process. The 6,027 new oil and gas permits approved in 2025 represent the highest number in 15 years and reflect the administration’s streamlined approach to environmental review and permitting. Historically, permit applications for oil and gas development have required lengthy environmental impact assessments, public comment periods, and consultation with tribal nations. The acceleration suggests these processes have been streamlined. The warning here concerns long-term environmental costs. Federal law has historically required Environmental Impact Statements (EIS) and environmental reviews before approving oil and gas permits, partly to ensure that public lands are managed for “multiple use” including recreation, wildlife, and conservation.
Rapid permitting can mean abbreviated environmental review. The Trump administration’s position is that these regulatory processes unnecessarily slow development, but environmental groups argue that thorough environmental review is essential to protect public lands and water resources from degradation. Additionally, there is a limitation on revenue and actual drilling speed. While 328,000 acres were leased in 2025 generating $356.6 million, this revenue is a one-time payment for lease rights. The actual taxes and royalties from oil production occur only if wells are drilled and oil is extracted. Not every acre that is leased will be drilled, and the timeline from lease sale to first oil production can span years or decades. The acceleration of permits does not automatically accelerate actual development or revenue collection.
Coal Mining Expansion and the Broader Mining Agenda
While oil and gas expansion dominates the headlines, the Trump administration has also aggressively expanded coal mining access to federal lands. In September 2025, the administration opened 13.1 million acres of public land to coal mining. This represents a separate but related effort to maximize extractive resource development on federal lands. Combined, the coal and oil/gas expansions represent a dramatic reversal from the Biden administration’s approach of moving away from fossil fuel development on federal lands.
The example here is instructive: the 13.1 million acres opened to coal mining compares to the 328,000 acres actually leased for oil and gas in 2025. While the acreage available for coal is vastly larger, actual leasing volumes remain modest. This demonstrates a broader reality: making land “available” for resource extraction is different from ensuring extraction actually occurs. Market demand, commodity prices, and economic feasibility ultimately determine what gets developed, not merely the removal of regulatory barriers.
Looking Forward: Legal Challenges and the Real Timeline for Development
The Trump administration’s expansion agenda will almost certainly face legal challenges. Environmental groups, some western states, and Alaska Native communities have already filed lawsuits challenging lease sales and the reversal of environmental protections. The legal process can delay or block implementation of new leases, particularly if courts find procedural violations in environmental review or failure to consult affected tribes. The development timeline from lease sale to first oil production typically spans 3-10 years for onshore projects and 10+ years for offshore projects, meaning that leases sold in 2025-2026 may not produce oil until the 2030s.
The forward outlook is uncertain because global oil markets matter more than domestic policy. Oil prices influence whether companies invest in expensive Arctic or deepwater development. If oil prices remain low, much of the newly available acreage will remain undeveloped regardless of administrative support. Conversely, if prices rise, the Trump administration’s removal of regulatory barriers could accelerate development substantially. The administration has removed obstacles, but market forces and legal challenges will ultimately determine the pace and extent of actual drilling on federal lands.
Conclusion
The Trump administration is pursuing an aggressive expansion of oil and gas development on federal lands and waters. The scale is substantial: over 200 million acres of western BLM lands are open to leasing, 328,000 acres were actively leased in 2025, and the administration is proposing to open an additional 1 million acres in California and 13 million acres in Alaska. Offshore, the revocation of Biden-era restrictions affects 625 million acres, with 1.27 billion acres proposed for future lease sales.
These figures represent a dramatic policy shift toward fossil fuel development on public lands. However, acreage available for development does not automatically translate to development occurring. Legal challenges, global oil markets, technical feasibility, and the multi-year timeline from lease to production all affect actual outcomes. Tracking what the Trump administration actually opens to development is important for citizens, policymakers, and anyone concerned with how federal lands are managed—but the true measure of impact will be which of these lands are actually leased, developed, and producing oil over the coming decade.
