Mayor Eric Garcetti unveiled a sweeping plan for a more sustainable Los Angeles on Monday, calling for dramatic changes to the car culture, built environment and air quality of America’s second-largest city.

The mayor’s sustainability plan imagines a city where, by the mid-2030s, 80% of the cars run on electricity or zero-emission fuel, 80% of the electricity comes from renewable sources and Angelenos drive 2,000 fewer miles each year than they do now. It’s a far cry from today’s L.A., where gridlock, tailpipe pollution and smoggy air have come to define a way of life.

Garcetti cited the “existential threat” of climate change, which scientists say is fueling bigger and deadlier heat waves, wildfires and floods in California and around the world. He said he worries that if Los Angeles doesn’t take aggressive action now, in 50 years the city will have little time for priorities other than survival.

“Los Angeles needs to lead, but the whole world needs to act. This plan gives us a fighting chance,” Garcetti said in an interview. “It’s sort of a ‘greenprint’ for every other city in the country and the world, hopefully.”
