California Must Improve Transportation to Meet Climate Goals

“Two factors trigger all this (pollution), and they feed on each other,” said Matthew Lewis, an environmental consultant and spokesman for the pro-housing group California YIMBY. “One is sport utility vehicles,” he said, noting that state tailpipe standards allow larger SUVs, or those with four-wheel drive, to emit more than cars.

“The other is the failure of cities to build more housing and mass transit,” Lewis said. “You combine those things, and it’s a ticking climate bomb.”
