The Trump administration is rolling back several major climate policies, including two rules that target planet-warming pollution from vehicles and power plants, in a major blow to America’s progress on climate action.

The EPA administrator says he is rolling back dozens of environmental rules, including those crucial to California programs on climate change and electric vehicles, and closing offices that worked to lower pollution in poor communities.

The Trump administration announced a blitz of pollution and climate regulation rollbacks at the U.S. Environmental Protection Agency that target, among other things, the agency’s landmark finding that greenhouse gas emissions harm public health.

The EPA under President Trump is taking aim at foundational climate-change laws, which could fundamentally change America.

The Environmental Protection Agency has signaled that it will slash several regulations aimed at cutting pollution and mitigating climate change.
