Why the focus on cars and light trucks?

Transportation is the biggest single source of greenhouse gases in California. In the Bay Area, it accounts for 41 percent of our overall emissions, most of that comes from personal travel in on-road vehicles. To reduce our contribution to global warming, the region must pursue multiple transportation and land use strategies.

Plan Bay Area will:

1. Reduce the separation of land uses (jobs, stores, schools, and homes) and encourage more complete, mixed-use communities, so people can drive less and walk, bike or use more transit;
2. Cluster more homes, jobs and other activities around transit, so people can more easily use transit rather than drive; and
3. Plan land uses and transportation together, to reduce traffic congestion, improve vehicle speeds, reduce emissions from idling and other inefficiencies.
