Trump revokes Obama-era greenhouse gas harm ruling

US President Donald Trump has revoked the scientific ruling underpinning federal actions designed to curb greenhouse gases.

During Barack Obama’s first term in office, the Environmental Protection Agency (EPA) decided that six key planet-warming greenhouse gases, including carbon dioxide and methane, were a danger to human health.

The EPA’s 2009 ‘endangerment finding’ became the legal bedrock for federal efforts to reduce emissions produced by vehicles, power plants and the oil and gas sectors.

Republican President Trump claimed the endangerment ruling had damaged the American automotive industry and drove up prices for American consumers. Trump said: “This radical rule became the legal foundation for the Green New Scam, one of the greatest scams in history.”

Reversing the finding will reduce automobile manufacturers’s costs by $2,400 per vehicle, the White House claimed.
Former President Obama issued a response defending the endangerment ruling via the X social media channel: “Without it, we'll be less safe, less healthy and less able to fight climate change — all so the fossil fuel industry can make even more money.”
