Cars and Global Warming
Policy Options to Reduce Greenhouse Gas Emissions from Massachusetts Cars and Light Trucks

Executive Summary

The transportation sector produces roughly 35 percent of Massachusetts’ global warming pollution. Cars and Global Warming explains how Massachusetts could reduce global warming emissions from passenger vehicles by adopting California’s clean car standards. By requiring advanced-technology vehicles—including hybrid-electric and eventually hydrogen vehicles—and establishing global warming pollution standards, the clean cars program will begin to reduce Massachusetts’ contribution to global warming.
