Smart Growth initiatives directly impact how much time you spend in your car, a new study shows. Published in The B.E. Journal of Economic Analysis and Policy, San Francisco State University professor Dr. Sudip Chattopadhyay's findings state that, "a 10 percent increase in smart growth amenities - measured by residential and job density and per-capita transit spending - leads to a 20 percent reduction in miles driven." The study also revealed that Smart Growth strategies were even more effective than taxation strategies in reducing driving.

"Chattopadhyay said his findings lend support to California's State Bill 375 and Assembly Bill 32," says Schmitt. "Both laws promote efficient land use to help curb global warming. The study did not examine other benefits of smart growth, such as better health and environmental outcomes."
