Noting that fuel efficient cars won’t do nearly enough to reach California’s ambitious goal of reducing Greenhouse gas emissions to 1990 levels by 2020, California is about to take the next step and pass a bill that reduces those gasses by reducing urban sprawl. The state has recognized that smart urban planning is a crucial piece of the puzzle.

While it remains to be seen whether California will be able to successfully meet the rigorous guidelines it laid out in its landmark AB 32 bill, the state is on the cusp of taking a huge step forward with the imminent adoption of SB 375.
The bill, which would reduce sprawl by requiring California’s 17
metropolitan planning organizations (MPOs) and its regional
transportation plans to meet strict GHG emission targets, was sponsored
by Darrel Steinberg (D-Sacramento), the incoming state Senate Leader.
