EPA to Scrap Landmark US Emissions Policy in Major Rollback

The US Environmental Protection Agency plans this week to repeal a policy that provides the legal foundation for a raft of rules regulating greenhouse gas emissions, marking President Donald Trump’s most consequential retreat from the fight against climate change.

A move to scrap the Obama-era endangerment finding, a 2009 scientific determination that greenhouse gases endanger human health and welfare, is expected as early as Wednesday, according to a person familiar with the details. The policy underpins rules including federal emissions standards for cars and trucks.
