The Environmental Protection Agency (EPA) has officially repealed the Endangerment Finding, a landmark scientific determination that has served as the legal and scientific foundation for federal climate regulations for over fifteen years. The decision, announced this week, has sparked immediate and intense backlash from environmental advocates, public health organizations, and the outdoor recreation industry. Protect Our Winters (POW), a leading advocacy group representing the "Outdoor State"—a coalition of 181 million outdoor enthusiasts—responded to the announcement by calling for the immediate resignation of EPA Administrator Lee Zeldin. The repeal is viewed by critics as a fundamental abandonment of the agency’s mission to protect human health and the environment, signaling a seismic shift in American environmental policy.
The Endangerment Finding, originally issued in 2009, established that greenhouse gas (GHG) emissions, including carbon dioxide and methane, threaten the public health and welfare of current and future generations. By repealing this finding, the EPA effectively removes the primary legal mechanism used to regulate emissions from power plants, vehicles, and industrial sources under the Clean Air Act. Administrator Zeldin defended the move as a necessary step toward "regulatory clarity" and the prioritization of American energy independence, arguing that the previous finding was based on overreaching interpretations of executive authority. However, scientists and legal experts warn that the move ignores decades of peer-reviewed research and leaves the United States without a comprehensive framework to address the accelerating impacts of a warming planet.
Historical Context: The Rise and Fall of the Endangerment Finding
To understand the gravity of the current repeal, it is necessary to examine the legal history of the Endangerment Finding. The process began with the 2007 Supreme Court case Massachusetts v. EPA, in which the court ruled that greenhouse gases fit the definition of "air pollutants" under the Clean Air Act. The Court mandated that the EPA must determine whether these gases contribute to climate change that endangers public health.
In December 2009, following an exhaustive review of climate science, the EPA issued the Endangerment Finding. This document concluded that the atmospheric concentrations of six key greenhouse gases—carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride—endanger the health and welfare of the American public. This finding was not merely a symbolic gesture; it was a mandatory prerequisite for the implementation of the Clean Power Plan, fuel efficiency standards for vehicles, and methane leak detection requirements for oil and gas operations.
Since the beginning of the new administration in January 2025, the EPA has moved with unprecedented speed to dismantle these protections. The repeal of the Endangerment Finding represents the culmination of a broader deregulatory agenda aimed at reducing the "administrative burden" on the fossil fuel sector. Critics argue that by removing the scientific basis for regulation, the agency is intentionally blinding itself to the environmental realities that its charter requires it to manage.
The "Snow Drought" and the Climate Reality in the American West
The call for Administrator Zeldin’s resignation comes at a time of visible environmental distress across the United States, particularly in the mountain regions of the American West. Protect Our Winters has highlighted a severe "snow drought" currently affecting the Sierra Nevada, the Rockies, and the Cascades. Scientific measurements from the SNOTEL (Snow Telemetry) network and satellite data from NASA show that winter snowpack levels in several key basins are at historically low levels for this time of year, with some regions reporting less than 40% of their median seasonal average.
This phenomenon is not characterized by a lack of precipitation alone, but by "warm snow droughts," where unusually high temperatures cause precipitation to fall as rain rather than snow. This shift has devastating implications for the hydrological cycle of the West. Mountain snowpack acts as a natural reservoir, storing water during the winter and releasing it slowly during the spring and summer months.
When this reservoir fails to form, the consequences are multifaceted:
- Water Scarcity: Reduced snowpack leads to lower streamflows, tightening water supplies for agriculture and municipal use.
- Energy Production: Hydropower generation, which relies on consistent water release from high-elevation watersheds, faces significant disruptions.
- Wildfire Escalation: A thinner snowpack results in earlier soil drying, which effectively lengthens the wildfire season and increases the intensity of summer burns.
- Economic Loss: The outdoor recreation industry, which contributes $1.2 trillion to the U.S. GDP, is directly dependent on predictable winter seasons.
POW argues that the EPA’s decision to ignore the science behind these events is a direct affront to the communities currently living through them. The Endangerment Finding was specifically designed to recognize these types of threats—extreme weather, shifting precipitation patterns, and rising temperatures—and to provide the EPA with the tools to mitigate them through emission reductions.
The Economic Impact on the "Outdoor State"
The outdoor recreation economy is one of the most significant yet undervalued sectors of the American economy. According to data from the Bureau of Economic Analysis (BEA), the outdoor recreation industry accounts for 2.2% of the total U.S. GDP. This sector supports nearly 5 million jobs, many of which are located in rural and mountain communities that have few other economic drivers.
The "Outdoor State" comprises 181 million Americans who participate in activities ranging from skiing and snowboarding to fishing, hiking, and hunting. For these individuals and the businesses that serve them, the repeal of the Endangerment Finding is viewed as an existential threat. Protect Our Winters emphasizes that without stable winters and clean water, the infrastructure of the outdoor economy—ski resorts, guide services, gear manufacturers, and local hospitality businesses—cannot survive.
The repeal is expected to lead to an immediate increase in localized pollution and a long-term acceleration of warming trends. For the outdoor industry, this translates to shorter seasons, increased operational costs for snowmaking, and a decline in participation as landscapes are altered by fire and drought. POW’s demand for Zeldin’s resignation is rooted in the belief that an EPA Administrator who prioritizes the short-term interests of the fossil fuel industry over a trillion-dollar recreation economy is failing in their fiduciary and civic duty.
Chronology of EPA Actions Since January 2025
The repeal of the Endangerment Finding is the latest in a series of aggressive policy shifts under the current EPA leadership. A timeline of these actions reveals a systematic effort to roll back environmental oversight:
- January 2025: Immediately following the inauguration, the EPA issued a stay on the implementation of stricter methane emission standards for new and existing oil and gas wells.
- February 2025: The agency announced a "re-evaluation" of the Waters of the United States (WOTUS) rule, signaling a move to reduce federal protections for wetlands and ephemeral streams.
- March 2025: The EPA moved to weaken fuel economy standards for passenger vehicles, citing a need to lower vehicle costs for consumers, despite warnings from the transportation sector regarding global competitiveness in the electric vehicle market.
- April 2025: The formal announcement of the repeal of the Endangerment Finding was made, accompanied by a statement that the agency would no longer use "social cost of carbon" metrics in its benefit-cost analyses for new regulations.
These actions have been described by environmental legal scholars as a "scorched earth" approach to deregulation. By targeting the Endangerment Finding, the EPA is not just changing a specific rule; it is attempting to dismantle the very logic that allows for environmental regulation in the 21st century.
Official Responses and Industry Reactions
The reaction to the repeal has been sharply divided along industrial and political lines. Representatives from the American Petroleum Institute (API) and other fossil fuel advocacy groups have cautiously welcomed the move, stating that it will provide the "regulatory certainty" needed for long-term investment in domestic energy production. They argue that climate policy should be set by Congress, not by administrative agencies utilizing decades-old statutes.
Conversely, a coalition of 22 State Attorneys General has already announced intentions to file suit against the EPA, arguing that the repeal is "arbitrary and capricious" under the Administrative Procedure Act. "You cannot simply wish away the laws of physics and chemistry," said one lead attorney in a prepared statement. "The science of the Endangerment Finding has only become more robust since 2009. To repeal it now is a violation of the EPA’s legal mandate to protect the public."
Public health organizations, including the American Lung Association, have also expressed alarm. They point out that greenhouse gas emissions are often co-pollutants with particulate matter and ozone, which contribute to asthma, cardiovascular disease, and premature death. By weakening the authority to regulate GHGs, the EPA is indirectly allowing for higher levels of traditional air pollutants that disproportionately affect vulnerable populations, including children and the elderly.
Analysis of Implications: A Precarious Future
The repeal of the Endangerment Finding places the United States in a precarious position, both domestically and internationally. Domestically, the move creates a period of intense legal instability. As the case winds through the court system, businesses will face uncertainty regarding which standards will ultimately apply, potentially chilling investment in clean energy technologies.
Internationally, the move signals a retreat from global climate leadership. The United States’ ability to encourage other high-emitting nations to reduce their carbon footprint is significantly diminished when its own environmental agency denies the necessity of domestic regulation. This could lead to a breakdown in international climate agreements, such as the Paris Accord, as other nations may follow the U.S. lead in prioritizing short-term industrial gains over long-term environmental stability.
Furthermore, the dismissal of the Endangerment Finding ignores the mounting costs of climate inaction. The National Oceanic and Atmospheric Administration (NOAA) has reported a steady increase in the frequency and cost of billion-dollar weather and climate disasters. By abandoning the tools designed to mitigate these risks, the EPA is shifting the financial burden of climate change from the polluters to the taxpayers who must fund disaster relief and infrastructure repair.
Conclusion: The Call for Accountability
Protect Our Winters’ demand for Lee Zeldin’s resignation is a call for a return to science-based governance. The organization maintains that the EPA cannot fulfill its mission while led by an individual who actively works to dismantle the agency’s scientific and legal foundations. As the American West grapples with a historic snow drought and the outdoor economy faces an existential threat, the debate over the Endangerment Finding is more than a legal technicality—it is a struggle over the future of the American landscape.
The coming months will likely see a protracted legal battle over the repeal. However, the immediate impact is a clear signal that the current EPA leadership intends to prioritize the fossil fuel industry at the expense of public health, the environment, and the $1.2 trillion outdoor recreation economy. For the 181 million members of the Outdoor State, the message is clear: the protection of the places they live, work, and play is no longer a priority for the agency tasked with their defense.
