In a significant policy shift, President Donald Trump and EPA head Lee Zeldin announced the finalized repeal of the 'endangerment finding,' a key scientific determination that greenhouse gas emissions endanger public health. This repeal, described by Trump as 'the biggest deregulatory action in US history,' dismantles federal greenhouse gas emission standards for vehicles and other industries. Critics argue that this move will lead to increased gas prices and that the claimed savings of $1.3 trillion by 2055 are misleading, as the administration's own analysis suggests the new rule will push up costs for consumers (The Guardian, February 15, 2026). Furthermore, the repeal could jeopardize other climate regulations, including those on carbon dioxide emissions from power plants and methane leaks, raising concerns about the broader implications for U.S. climate policy (The Guardian, February 15, 2026).
