EPA Considers Scrapping Climate Policy Undergirding Emissions Rules

The US EPA is considering scrapping a landmark climate policy, the endangerment finding, which has been the legal basis of climate rules under the Clean Air Act since 2009. The plan, which is still subject to change, would eliminate limits on vehicle greenhouse gas emissions. If implemented, it could face challenges from environmental groups and have unintended consequences for industries like electric utilities and oil companies.

The U.S. Environmental Protection Agency (EPA) is proposing to rescind the 2009 endangerment finding, which has served as the legal basis for climate regulations under the Clean Air Act. This move, still a draft proposal subject to change, could eliminate limits on vehicle greenhouse gas emissions and has significant implications for environmental policy and various industries.

The endangerment finding, issued in 2009, determined that greenhouse gas emissions endanger public health and welfare, providing the legal justification for regulating them under the Clean Air Act. The EPA, under Administrator Lee Zeldin, announced in March that it would reconsider this finding as part of broader environmental rollbacks.

The draft proposal, which has not been released for public comment, aims to eliminate all resulting limits on motor vehicle greenhouse gas emissions. This could have substantial impacts on industries like electric utilities and oil companies, which have been subject to these regulations.

Environmental advocates, such as David Doniger of the Natural Resources Defense Council, argue that the proposed repeal is not justified under the law and contradicts scientific evidence. Thomas Pyle of the Institute for Energy Research, however, supports the EPA's efforts, claiming that Congress never mandated the agency to act on climate change.

The endangerment finding has allowed for seven regulations on vehicle emissions with a cost of over $1 trillion, according to the EPA. Richard Revesz, a law professor at New York University, suggests that while the move may not hold up in court, it will still affect U.S. climate policy until a final judicial decision is made.

The Clean Air Act, established in 1970, has a 40-year track record of reducing dangerous pollution and preventing premature deaths. The act has been instrumental in reducing ground-level ozone, mercury emissions, and acid rain pollutants, among other achievements [2].

If the endangerment finding is rescinded, it would call into question the EPA's regulation of greenhouse gases, potentially leading to significant changes in environmental policy and industry regulations. The proposal comes at a time when global warming emissions are under scrutiny, and numerous attempts are being made to limit the EPA's actions under the Clean Air Act [2].

The EPA's decision to reconsider the endangerment finding is part of a broader trend of deregulation, with the agency aiming to strike a balance between economic concerns and environmental protection. The proposed repeal, however, faces potential legal challenges and could have unintended consequences for industries and the environment.
