Trump dismantles legal basis for US climate rulesWhile the Endangerment Finding initially applied only to a section of the Clean Air Act governing vehicle emissions, it was later incorporated into other regulations. (Photo: AFP)WASHINGTON (UNITED STATES) - President Donald Trump on Thursday revoked a landmark scientific finding that underpins US regulations aimed at curbing planet-warming pollution, marking the administration's most far-reaching rollback of climate policy to date. The 2009 "endangerment finding" was a determination under then-president Barack Obama that six greenhouse gases threaten public health and welfare by fueling climate change. While it initially applied only to vehicle emissions, it later became the legal foundation for a broader suite of climate regulations. The Supreme Court has re-affirmed the endangerment finding multiple times -- most recently in 2022, when the court's composition was much the same as today.
