In 2019, buildings in San Francisco were responsible for 41% of citywide emissions, with commercial buildings contributing 18% and residential 23%. Eighty-two percent of building emissions stem from the use of natural gas, primarily for water heating and space conditioning. Similar numbers are common in jurisdictions across California. Eliminating fossil fuel use in both electricity generation and in buildings is central to achieving San Francisco’s and California’s emissions-reduction goals. Building electrification is the transition of services that currently rely on fossil fuels to efficient use of renewable electricity. To achieve zero net emissions by 2050 and limit global temperature rise to 1.5°C, aggressively increasing electrification in new and existing buildings that are powered with renewably generated electricity is necessary.
