Upcoming Virtual Public Workshop: Updates and Clarifications to the SCS Evaluation Process

January 16, 2024

en español

The California Air Resources Board (CARB or the Board) invites you to participate in a virtual public workshop to learn about CARB’s approach to evaluating sustainable communities strategies during the 4th Cycle and to discuss its process for updating the Sustainable Communities Strategy Program and Evaluation Guidelines (Guidelines) moving forward. This public workshop intends to clarify the existing 2019 Final Sustainable Communities Strategy Program and Evaluation Guidelines (2019 SCS guidelines) and communicate expectations of the upcoming 4th Cycle SCS. In addition, this workshop will also discuss the process and timeline for medium- and long-term changes to the guidelines.

The virtual public workshop will be held via Zoom webinar at the following date and time.

Date:             Tuesday, January 16, 2024
Time:             10:00 a.m. – 11:30 a.m.
Location:       Virtual Workshop


This meeting will be recorded. Approximately two weeks after the meeting date, a link to the recording will be made available and posted on Sustainable Communities | California Air Resources Board.

How to Participate

To participate in the workshop, please register before the workshop begins. After registering, you will receive a confirmation email with information to join the Zoom webinar through a computer, digital device, or phone. During the workshop, participants will be able to ask questions and provide comments through the Zoom “raise hand” feature or via phone line.


SB 375, the Sustainable Communities and Climate Protection Act of 2008, requires MPOs to prepare a sustainable communities strategy (SCS) as part of their regional transportation plans. The purpose of the SCS is to integrate land use and transportation planning to support the State’s climate goals. To help guide these regional planning efforts, CARB is required to establish regional greenhouse gas (GHG) emission reduction targets for 2020 and 2035 and to evaluate SCSs to determine whether the SCS would meet the targets when implemented.

Pursuant to SB 375, CARB staff last updated the program guidelines which govern expectations and the review process for SCS in 2019. Since the release of the 2019 SCS guidelines, most MPOs have completed their 3rd Cycle of SCSs, and some MPOs have begun their 4th Cycle.

As the 4th Cycle begins, CARB staff wants to ensure that all MPOs consider recent changes in external conditions (e.g., market, technological, and economic) that affect planning assumptions and new State policies and regulations. For instance, the GHG quantification of a zero-emission vehicles (ZEV) incentive strategy needs to account for updated conditions such as the recent adoption of the Advanced Clean Cars II regulation, the federal ZEV incentives program, and the reduction in market costs for ZEVs compared to conventional vehicles.

In addition, CARB staff would like to discuss and solicit feedback on future plans to address issues requiring greater attention by clarifying and updating the 2019 SCS guidelines periodically through a public process.
