The California Air Resources Board (CARB) is currently evaluating its transit-related quantification tools and resources to best support quantifying and reporting on estimated benefits from projects funded through California Climate Investments programs. This effort includes incorporating important updates and maintenance to the existing methods; developing new or additional methods and components; and collecting invaluable feedback from users and program stakeholders throughout the process. CARB has invited transit stakeholders to participate in a short survey to share early feedback on experience with existing transit quantification methodologies and calculator tools, and to help inform the direction on an updated, streamlined quantification resource to support future transit projects. At the end of the survey, they also encourage respondents to share contact information and level of preferred involvement as this effort moves forward. Responses are requested at this link by October 30, 2026,  at 5 p.m. PT. For additional questions, please connect with CARB via email at ggrfprogram@arb.ca.gov.
