1
Transportation’s share of our carbon footprint Transportation is growing faster than other sectors, accounted for half the growth in emissions from 1990-2006
2
Transportation emissions 61% of transportation emissions come from cars. Can’t reduce enough just by improved fuel efficiency.
3
Going car free = huge dent to your personal carbon footprint.
4
Good news: the market is changing. Question is, how can we support that trend? Driving has been on the decline for the last 8 years nationally, down 7.4% since 2004. 18 states nationwide saw double-digit declines in VMT (vehicle miles traveled).
5
2009 Moving Cooler report Can reduce transportation emissions by 50% by 2050 24% via a range of strategies to reduce driving 47% total if combined with congestion pricing and pay-as- you-go insurance. No magic bullet!
6
Strategies to reduce emissions from transportation Pricing and taxes – gas, VMT Incentivize smart growth land use Make non-motorized transport safe and attractive Invest in public transportation Make ridesharing, carsharing and other commuting strategies viable options Regulatory strategies
7
Potential for reducing transportation emissions by investing in smart growth. NRDC study: If all developments were infill/location efficient for 10 years, could reduce national emissions by 10% (and save families a lot of $)
8
Examples from California SB375: Sustainable Communities law. Sets emissions reductions targets for transportation for each MPO in the state, cities then figure out how to meet it. 6-8% by 2020, 13-16% by 2035. “Level of Service” reform. Recently repealed “LOS” car-oriented performance measures from state environmental regs which were requiring more sprawling development.
9
Examples from California San Francisco’s “transit first” policy: " Decisions regarding the use of limited public street and sidewalk space shall encourage the use of public rights of way by pedestrians, bicyclists, and public transit, and shall strive to reduce traffic and improve public health and safety." (City Charter, Section 16.102)
