Vehicle Miles Traveled:
Integrating the California Environmental
Quality Act with the California Global
Wanning Solutions Act*

The California Global Warming Solutions Act of 2006 (AB 32) commits
California to reduce its greenhouse gas (GHG) emissions to 1990 levels by
2020. The sector is the top GHG emitter in California,
contributing roughly 40 percent of all California emissions. Poor fuel
efficiency and high vehicle miles traveled (VMT) are primary contributors to
transportation sector GHG emissions. Meeting California's GHG emissions
reduction goals requires reductions in both per-mile emissions and vehicle
miles traveled. Fuel efficiency has been addressed historically by federal
Corporate Average Fuel Economy (CAFE) standards, and California has
passed its own legislation regulating GHG emissions from vehicles. Vehicle
