House Democrats Will Call for 100% Clean Cars by 2035

House Democrats on June 30 will issue an ambitious plan to combat climate change, a move intended to reassure their base of supporters but that’s sure to inflame opponents on the right.

The proposal will be released at an event at the U.S. Capitol with Speaker Nancy Pelosi and several other Democratic lawmakers.

In a statement announcing the June 30 unveiling, the committee offered no details on the plan but called it “a comprehensive congressional action plan to solve the climate crisis.” A spokesman for committee Democrats didn’t respond to a request for comment on specifics.
