Trump administration may let California keep emissions standards / by James Gosling

From the San Francisco Chronicle:

The Trump administration may be quietly conceding defeat to California on car tailpipe emissions, the biggest battleground in the state’s showdown with President Trump over climate change.

Environmental Protection Agency chief Scott Pruitt backed away last month from his threats to challenge California’s unique legal authority, known as a waiver, to set aggressive limits on vehicle emissions, including greenhouse gases.

Although Pruitt left the door open to a future challenge, experts said he is running out of time to stop California from dictating national pollution standards on cars, the nation’s primary source of greenhouse gas emissions.
