Trump to Scrap Key Climate Ruling, Unleashing Sweeping Deregulation

• Trump administration plans to overturn an Obama-era scientific finding that carbon dioxide endangers human health.
• This move would remove the legal basis for federal greenhouse gas emissions regulations, marking the most sweeping climate policy rollback to date.
• The repeal, to be unveiled this week by the EPA, would apply to car emission standards but not stationary sources.
• The EPA Administrator Lee Zeldin reportedly called it "the largest act of deregulation in the history of the United States."
• The repeal is expected to face significant legal challenges, as a federal court already ruled against a related advisory group.
