Clean car standards are under attack, threatening public health, the economy and the rights of states.

We are facing an unprecedented assault on the Clean Air Act, as the Trump Administration looks to revoke the rights of states to protect their citizens from harmful vehicle pollution.


Your voice is needed. Tell the government to stop the assault.


Who Supports cleaner cars?

If you add all of the states who have either joined litigation to protect the standards or vowed to reduce their greenhouse gas emissions, they represent 49 percent of U.S. vehicles. If you add new vehicles from cities voicing opposition to the rollback (outside the states already counted) that means all these climate-protecting states and cities amount to more than half (55 percent) of the U.S. auto market.
