California Air Resources Board

SB 150 (Allen, Chapter 646, Statutes of 2017) requires the California Air Resources Board to prepare a report to the Legislature starting in 2018, and every four years thereafter, to discuss progress related to the Sustainable Communities Act, or SB 375, implementation. This progress report uses data-supported metrics to assess progress on transportation, housing, and land use strategies, identifies best practices and challenges to achieving greater reductions, and discusses the impact of State policies and funding.
