In a significant rollback of environmental regulation, Donald Trump has revoked the endangerment finding that allowed the federal government, specifically the Environmental Protection Agency (EPA), to impose limits on greenhouse gas emissions. This decision, which Trump has labeled as the "single largest deregulatory action in American history," has drawn sharp criticism from former President Barack Obama and numerous environmental advocates, who argue that it prioritizes corporate profits over public health and safety.

The endangerment finding, established in 2009, established the legal groundwork for the EPA to regulate emissions from vehicles, power plants, and industrial sources by acknowledging that greenhouse gases pose a danger to public welfare. Critics of the decision, including John Kerry, expressed deep concern that this repeal would compromise Americans' well-being and undermine efforts to combat climate change, ultimately benefiting the fossil fuel industry at the expense of environmental safeguards.

In response to this rollback, various environmental organizations have announced their intent to challenge Trump's decision in court, highlighting a growing resistance against deregulatory actions that threaten environmental progress. As climate change continues to present unprecedented challenges, the implications of this decision could have far-reaching consequences for environmental policy and public health in the United States.
