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.

The Draft 2022 Progress Report and new SB 150 Data Dashboard is now available for public comment through Thursday, July 14, 2022. Comments can be submitted to sustainablecommunities@arb.ca.gov
