Vehicles powered by clean fuels are increasingly becoming more popular with consumers. Thousands of alternative fuel vehicles (AFVs) are on the road today in San Francisco. With a growing interest in clean transportation, enhancements and improvements to these vehicles and fuels are in full swing, offering an expanding number of options to consumers. The newfound popularity of clean fuels and vehicles is transforming how we approach transportation in San Francisco. SF Environment is engaged in several clean fuel and clean vehicle efforts that aim to create a comprehensive local and regional AFV network. We are also working on greening and reducing the size of the municipal fleet with the help of the San Francisco Clean Cities Coalition (SFCCC), which encourages both the public- and private-sector fleets to use alternative fuels. The SFCCC also works to promote idle-reduction measures and inform stakeholders of incentives, new technologies, and other opportunities.
