The feds are taking on California’s plan to limit tailpipe emissions of greenhouse gases and discussing the idea of low carbon fuel, but California has one other major idea to curb vehicle pollution, says the state senator who pushed through the tailpipe emissions law, Fran Pavley. The idea: drive less.

“No matter what we do on the clean car regs, with the gross of the state… and the sprawl out into the suburbs and the rural areas, we are going to be going in the wrong direction. And that’s something the federal government hopefully will eventually look at — land use,” she said by phone, when asked about next steps for vehicle pollution.

2008’s Senate Bill 375 by Darrell Steinberg set up targets for coordinated planning of transportation, land use and housing with regional reduction targets for greenhouse gases. At the time the bill passed, California was expecting its population to rise to 46 million by 2030 from 38 million.
