With a population of approximately 883 thousand residents, San Francisco is California’s fourth-largest city. 

San Francisco and the surrounding Bay Area have their fair share of climate change challenges. Over the past century, the Bay’s sea level has risen eight inches, damaging local population and ecosystems. The damage is compounded by unprecedented erosion brought on by the 2015-2016 El Niño storms. The 2012-2016 drought drove statewide moisture to the lowest levels seen in more than 1,000 years. As climate change drags on, the whole Bay expects more “boom and bust” rain cycles with very wet and very dry years. These cycles exacerbate the area’s “large-fire” years, which have gotten steadily worse and more common over the past 80 years.

The City of San Francisco has ambitious climate change prevention and preparedness goals, having successfully reduced greenhouse gas emissions by 23% below 1990 levels, even as its economy and population have grown. San Francisco’s Municipal Code calls for substantial reductions in greenhouse gas emissions with goals of  40% reductions below 1990 levels by 2025, and 80% reductions by 2050

Mostly hydropower, but also some solar and wind power, provide more than 70% of the electricity consumed in San Francisco
