Some of San Francisco’s strategies include a public transportation system used widely by commuters, BART and Muni; nearly a quarter of San Franciscans get to work this way. Among the city’s public transportation system, 68 percent of the options are eco-friendly, according to the study, and the aim is for an all-electric fleet by the year 2040. Another 3.4 percent of residents bike to work.

The city’s recycling program is available to 95 percent of households—and 65 percent of households use it. San Francisco spearheads its own citywide environmental policies through its Climate Action Plan. Community projects that support sustainable practices can earn grants to continue their strategies from a grant pool of $900k established last year. The grants were awarded for projects such as removing invasive species and planting native trees and plants in the Portola neighborhood, giving residents induction cooktops and cookware supplies to promote the switch away from natural gas and electric cooking, and teaching parents of newborns to use bottles and food containers free of endocrine disrupting chemicals.
