- Trump administration approves BP's Kaskida ultra-deepwater oil drilling project in Gulf of Mexico — The Trump administration's Interior Department approved BP's $5 billion Kaskida project, an ultra-deepwater oil drilling operation in the Gulf of Mexico that will drill 6,000 feet into water and extend 6 miles into the seabed—deeper than Mount Everest's height. The project is expected to extract 80,000 barrels of oil daily from six wells starting in 2029. Environmental groups filed a lawsuit on the 16th anniversary of the 2010 Deepwater Horizon disaster, alleging the project poses catastrophic environmental and community risks and that BP has failed to demonstrate safe drilling capabilities or adequate containment measures for potential spills of up to 4.5 million barrels.
Feb 12, 2026 EPA revoked the 2009 endangerment finding underpinning climate regulation Tier 1 · Primary Economic Structure
The EPA eliminated the legal foundation for federal greenhouse gas regulation, a move projected to add billions in pollution and health costs while benefiting fossil fuel interests.
Supporting reports
- EPA revoked endangerment finding for greenhouse gas emissions — The Environmental Protection Agency revoked the endangerment finding that has been the basis for regulating emissions from cars and power plants since 2009. The finding reflected scientific consensus that greenhouse gases produced by burning fossil fuels endanger the health and general welfare of the American people. The Trump administration claims the revocation will save Americans $1.3 trillion, primarily through cheaper cars and trucks, but did not factor in costs of extreme weather or pollution-related health issues.
- Trump administration announces repeal of 2009 endangerment finding on greenhouse gases — The Trump administration, led by EPA Administrator Lee Zeldin, announced it will formally rescind the 2009 Obama-era endangerment finding that determined CO2 and other greenhouse gases endanger public health and welfare. This finding has served as the legal foundation for federal climate regulations under the Clean Air Act. The White House press secretary characterized the action as "the largest deregulatory action in American history." Environmental groups have pledged legal challenges, arguing the move will expose Americans to climate risks and health harms while benefiting fossil fuel interests.
- Trump EPA rescinds 2009 endangerment finding, eliminating legal basis for federal climate regulations — The Trump administration, through EPA Administrator Lee Zeldin, finalized the rescission of the 2009 endangerment finding—the legal foundation for all federal climate regulations under the Clean Air Act. The administration characterized this as the "largest deregulatory action in American history" and claimed it would save $1.3 trillion, though provided no methodology. Environmental groups including the Natural Resources Defense Council, Earthjustice, and Sierra Club pledged immediate litigation. The move follows Trump's campaign-trail request for $1 billion from oil executives in exchange for scrapping environmental rules.
- Trump EPA revokes endangerment finding, eliminating climate pollution regulation authority — The Trump administration's EPA, led by Administrator Lee Zeldin, revoked the 2009 endangerment finding that authorized the agency to regulate greenhouse gas emissions from vehicles, power plants, and industrial sources under the Clean Air Act. Trump called it "the single largest deregulatory action in American history." The move eliminates the EPA's legal basis to impose emissions tracking, reporting, and limits on transportation sources, though stationary sources remain technically covered under a separate Clean Air Act section. Environmental groups and California have pledged legal challenges; experts project 18 billion additional tons of planet-warming pollution by 2055 and up to $4.7 trillion in climate and air-pollution costs.
- EPA moves to revoke greenhouse gas emissions authority — The Environmental Protection Agency moved to revoke its longstanding authority to regulate greenhouse gas emissions under the endangerment finding. EPA Administrator Lee Zeldin claimed the endangerment finding, which stated that greenhouse gases pose a threat to human health, was built on a "con job" and asserted that climate change does not endanger public health.
- White House issues fact sheet announcing EPA revocation of 2009 Endangerment Finding — The White House issued a fact sheet announcing that President Trump has revoked the EPA's 2009 "Endangerment Finding" that classified greenhouse gases as harmful to human health under the Clean Air Act. The document claims this action eliminates the regulatory foundation for vehicle emissions standards, fuel economy mandates, and power plant regulations. The fact sheet asserts the revocation will save American families an average of $2,400 on vehicle purchases and reduce overall regulatory costs by $1.3 trillion. The announcement includes statements from industry groups, conservative organizations, and Republican officials supporting the action.
Nov 20, 2025 Trump administration announced offshore oil and gas drilling expansion off California and Florida, reversing prior climate protections Tier 1 · Primary Economic Structure
A major fossil-fuel leasing expansion opposed by both a Democratic governor and Florida Republicans prioritizes extraction interests over bipartisan environmental and tourism concerns.
Supporting reports
- Trump administration announces expanded offshore oil and gas drilling off California and Florida coasts — The Trump administration announced a new federal petroleum leasing schedule for 2026–2031 that includes up to 34 auctions across U.S. waters: six off California, 21 off Alaska (including a region never drilled), and two in the eastern Gulf of Mexico off Florida. The move reverses Biden-era climate protections and reflects Trump's National Energy Dominance Council priority on fossil fuel expansion. California Governor Newsom rejected the plan; Florida Republicans, including Senators Scott and Moody, have signaled opposition due to tourism and environmental concerns.
Jul 29, 2025 EPA announced revocation of the 2009 endangerment finding on greenhouse gases Tier 1 · Primary Economic Structure
Rescinding the scientific basis for federal greenhouse-gas regulation would remove authority to address climate change under the Clean Air Act.
Supporting reports
- EPA head announced revocation of 2009 endangerment finding on greenhouse gases — EPA head Lee Zeldin announced that the Trump administration would revoke the 2009 "endangerment finding," a declaration that found that greenhouse gas emissions lead to global warming and threaten public health. Zeldin called the move, which would remove the federal government's authority under the Clean Air Act to regulate greenhouse gas emissions, the "largest deregulatory action in the history" of the US, if finalized.
- Environmental groups and former EPA leaders condemned endangerment finding revocation — Zeldin's announcement prompted widespread backlash from environmental groups, the scientific community, and three former EPA leaders. The executive director of the Natural Resources Defense Council told AP that the move "boggles the mind and endangers the nation's safety and welfare" as the US faces deadly floods and heat waves, adding that the council will sue the EPA if "this illegal and cynical approach" is finalized.
- EPA moves to rescind 2009 endangerment finding on greenhouse gases — Trump loyalists at the Environmental Protection Agency moved in August to rescind the agency's 2009 endangerment finding that has underpinned climate change regulatory efforts since the Obama administration. The move rejects widely accepted scientific consensus on climate change despite increased scientific evidence supporting the original finding.
Jul 22, 2025 EPA proposed eliminating the 2009 scientific finding that greenhouse gases endanger public health Tier 1 · Primary Economic Structure
Removing the legal basis for emissions standards would gut climate regulation and reject evidence-based environmental policy.
Supporting reports
- EPA proposes rule eliminating the endangerment finding for greenhouse gases — The Environmental Protection Agency proposed a new rule to eliminate the endangerment finding established in 2009 that, based on scientific evidence, determined that greenhouse gas emissions like carbon dioxide and methane warm the planet and endanger human life. Most vehicle, factory, and power plant emissions standards currently in place derive from this finding. EPA officials told the New York Times they intend to argue that climate regulations, rather than greenhouse gas emissions themselves, cause harm to human health through higher prices and reduced consumer choice.
