CARB California Climate Investment Quantification Methodologies
(Applications will open September 2025)
California Air Resources Board (CARB) is responsible for developing quantification methodologies (QMs) for estimating greenhouse gas emission reductions and other co-benefits from projects funded by the Greenhouse Gas Reduction Fund, collectively called California Climate Investments. Between Summer 2025 and Spring 2027, IST will convene subject-matter experts through technical review committees and community stakeholders through community collaborator committees. IST will facilitate public outreach and engagement for four QMs, associated calculator tools, and co-benefit assessment methods, collect critical feedback about implementation processes, and present CARB with a best-practices document for their future QM peer review process. Overall, this work will improve conceptual soundness and ensure stakeholder relevance of CARB’s QMs and improve public engagement in CARB’s QM development process.
There are four major components of the work:
- Provide a final presentation to CARB staff, a final report suitable for publication, and a public outreach report.
- Recruit and convene the Technical Review Committee for each QM that will review QM throughout its development process and provide feedback on the conceptual soundness of the QM as well as QM development process. Summarize the feedback and convey it to CARB QM development teams.
- Recruit and convene Community Collaborator Committee that will provide feedback on stakeholder effects and co-benefits that need to be reflected in the QMs. Summarize the feedback and convey it to CARB QM development teams.
- Convene public outreach sessions with community organizations to virtually receive stakeholder feedback through public meetings.
