The Trump administration is set to repeal the Endangerment Finding, a crucial scientific conclusion from the EPA that greenhouse gases threaten public health and contribute to climate change. This move, described as one of the largest acts of deregulation in U.S. history, aims to dismantle foundational climate policies put in place during the Obama era. The rollback is anticipated to impact environmental regulations across various sectors, including auto emissions standards, and may have severe implications for public health and air quality. Critics warn that this decision disregards established science and puts communities at increased risk of pollution and climate-related health issues.
