The Environmental Protection Agency (EPA) has taken a significant step by proposing to rescind the 2009 Endangerment Finding for Greenhouse Gases, a move that could drastically alter the landscape of environmental regulation in the United States. This finding, originally established in 2009, served as the foundation for the EPA’s authority to regulate greenhouse gas emissions from vehicles. The potential rollback would effectively repeal all regulations that currently govern highway vehicle emissions of greenhouse gases.
The 2009 Endangerment Finding had determined that six greenhouse gases, including carbon dioxide, methane, and hydrofluorocarbons, posed a threat to public health and welfare. This was particularly relevant to new motor vehicles and engines, as they contribute considerably to greenhouse gas pollution. The finding was instrumental in prompting a change under Section 202(a) of the Clean Air Act, enabling the EPA to set emissions standards. According to the act, elevated concentrations of greenhouse gases contribute to adverse changes in air quality, extreme weather events, and the spread of pathogens, which in turn affect public health.
EPA Administrator Lee Zeldin remarked on the prevailing narrative that views carbon dioxide solely as a pollutant. He emphasized the need to recognize the role of carbon dioxide for the planet. The EPA suggests that if their proposal is approved, it could result in the elimination of regulations costing over $54 billion annually, potentially saving $1 trillion overall. This aligns with a report by the US Department of Energy titled “A Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate,” which argues that the economic damage of CO2-induced warming may be overestimated and that aggressive mitigation measures might be counterproductive.
The move has initiated a public commentary phase, running until September 15, which allows stakeholders and the general public to weigh in through regulations.gov.
This proposed change has sparked debate among environmental groups and legal experts, particularly concerning its alignment with the goals of the Paris Agreement. The potential rescission marks a pivotal moment in environmental policy, with possible implications for international commitments and the U.S.’s role in global climate leadership.
