The Trump administration is set to revoke the Environmental Protection Agency's (EPA) 17-year-old scientific finding that greenhouse gases endanger public health and welfare, a critical legal basis for climate action under the Clean Air Act. This decision marks a significant shift in US environmental policy, particularly following a series of record-high temperatures and devastating climate-related disasters.

Legal and Regulatory Context

EPA Administrator Lee Zeldin, appointed by President Trump, is expected to finalize the repeal as part of a broader agenda to promote fossil fuel use, particularly coal. The White House has stated that these actions are intended to enhance US energy dominance and reduce costs. However, critics argue that this repeal will dismantle essential protections and exacerbate public health risks, particularly for vulnerable communities already facing high pollution levels.
The legal ramifications of this repeal are profound. The Trump administration's assertion is that the EPA lacked the authority to write such rules in the first place. This argument is anticipated to face significant legal challenges, particularly given the Supreme Court's past rulings which have affirmed the EPA's authority to regulate greenhouse gases as pollutants. The case could ultimately revisit the landmark 2007 ruling in Massachusetts v. EPA, a decision that recognized the threat posed by greenhouse gases.

Scientific Consensus Undermined

Despite the administration's claims, a panel from the National Academies of Sciences, Engineering, and Medicine (NASEM) recently reaffirmed that the evidence linking human-caused greenhouse gas emissions to climate change is irrefutable. Their findings, which were not solicited by the Trump administration during the repeal process, highlight the worsening impacts of climate change, including increased heat waves, severe storms, and more intense wildfires.
The implications of the repeal extend beyond legal frameworks. Environmental advocates argue that it represents a retreat from scientific understanding that could hinder future climate actions. Michelle Roos, executive director of the Environmental Protection Network, stated that the decision would lead to "dirtier air, higher health costs, and increased climate harm" for communities across the nation.

California's Response and Broader Implications

California, often at the forefront of environmental policy and regulation, is preparing to challenge the Trump EPA's actions. Governor Gavin Newsom has called for a special legislative session to bolster the state's legal defense against anticipated federal rollbacks of environmental protections, particularly those affecting air quality and climate change.
The stakes are high for California, whose environmental initiatives rely heavily on federal cooperation. Historical data indicate that the Trump administration faced significant legal setbacks during its first term, losing 83% of cases relating to environmental regulation rollbacks. This precedent gives hope to advocates who see the endangerment finding as critical in the fight against climate change.

Looking Forward: Potential Outcomes and Legal Challenges

As the Trump administration pushes through this repeal, the legal landscape will likely see intense battles in the courts, starting with the DC Circuit Court of Appeals. Climate action advocates, including the Natural Resources Defense Council, view this move as a direct attack on decades of environmental progress and are gearing up for a robust legal defense.
Legal experts predict that the repeal will face scrutiny under existing precedents, as the Supreme Court has previously upheld the EPA's authority to regulate greenhouse gases. However, the new conservative majority on the Court may interpret the law differently, complicating the landscape for environmental protections in the US.

Conclusion

The Trump EPA's planned revocation of the endangerment finding signifies not just a shift in regulatory strategy but a fundamental challenge to the scientific consensus on climate change. With legal challenges looming and states like California poised for a fight, the outcome of this decision may shape the future of environmental policy in the United States for years to come. The battle ahead will test the resilience of environmental law and the commitment to addressing climate change amidst a rapidly evolving political landscape.
