We can build our cities to be pedestrian, bicycle, and transit-friendly. This means concentrating new development close to BART and other transit lines. The Metropolitan Transportation Commission (MTC) has a plan that calls for 80% of all new development to be built in Priority Development Areas (PDAs). The California Air Resources Board scoping plan calls for quadrupling the proportion of trips taken by foot and increasing bicycle trips by nine times by 2030 (p102). Many cities in the Bay Area have Climate Action Plans that call for up to 80% reduction in greenhouse gases by 2050. These plans will only be implemented if activists demand policies and regulations to make them happen. That is the role of 350 Bay Area’s Transportation campaign–to be a voice that will relentlessly demand carbon-free transportation.
