CAPCOA Quantifying Greenhouse Gas Mitigation Measures

 

Explore the Handbook Update
February 14, 2022
Working together with industry experts, we are excited to share the release of an update to the CAPCOA Quantifying Greenhouse Gas Mitigation Measures, otherwise known as the CAPCOA Handbook.  Over the past decade, practitioners have relied heavily on this key reference document for developing VMT and emissions mitigation measures.  The update has expanded content as reflected in its new title, Handbook for Local Governments, Communities, and Project Developers for Assessing Greenhouse Gas Emissions Reductions, Climate Vulnerabilities, and Health and Equity.

Throughout the handbook there are a variety of updates that highlight current issues and strategies. A noteworthy update includes transportation mitigation strategies that have now been broken into two groups: those with sufficient substantial evidence through quantifiable measures and those requiring more evidence to support quantification (further details about the quantitative strategies begin on page 29 of the Handbook).

Driving Less Starts with Building Differently

Driving Less Starts with Building Differently

Jul 2, 2026 |

How much can planning decisions actually reduce driving? Our latest research introduces a statistical model that links built environment choices—such as density, transit service, walkability, and land use mix—to vehicle miles traveled (VMT). The findings give planners and policymakers practical, evidence-based tools to evaluate scenarios, understand tradeoffs, and make more informed transportation and land use decisions.

VMT under CEQA continues to evolve as agencies, practitioners, and decision makers work through analysis methods, mitigation feasibility, and defensible evidence. Our new Q&A resource offers practical answers on vehicle miles traveled, SB 743, mitigation program design, implementation, administration, and legal and strategic considerations.
