Such evidence has fostered consensus in California and elsewhere supporting public policy that promotes higher density development, greater mixture of land uses, and improved access to employment and housing. By passing the Sustainable Communities and Climate Protection Act of 2008, known as SB 375, California lawmakers acknowledged that land use planning could attenuate automobile use and, consequently, help to reduce greenhouse gas (GHG) emissions. Further, the law raises expectations for California communities to grow more equitably, with attention to affordable housing. It syncs local housing planning with regional transportation planning, requires local governments to specify actions to meet low-income housing needs, and can compel rezoning to speed affordable housing production where local inertia would delay it.
