We are excited to share the release of an update to the CAPCOA Quantifying Greenhouse Gas Mitigation Measures. Over the past decade, practitioners have relied heavily on this key reference document for developing VMT and emissions mitigation measures.
This guide helps transportation professionals determine if their travel forecasting models are suitable for environmental impact analyses, ensuring compliance with laws like NEPA and CEQA.
SB 743 requires evaluating transportation impacts using VMT instead of Level of Service (LOS).
Strategies like transit-oriented development, increasing residential density, and improving street connectivity can significantly reduce VMT and GHG emissions, with some measures achieving reductions of up to 31%.
Agencies should evaluate their models to ensure they provide reliable forecasts and meet CEQA standards for environmental impact analyses.
This guide helps agencies choose the right methods and tools to measure Vehicle Miles Traveled (VMT) for land use and transportation projects, supporting compliance with California’s SB 743.
