Commercial building electrification

Description: In San Francisco, CA, 44% of citywide emissions come from buildings (2.2 million metric tonnes CO2e in 2017), and half of those emissions come from the commercial sector. Within the commercial building sector, 28% of the emissions arise directly from electricity used to power these buildings.

San Francisco’s plan will require the largest commercial buildings to use 100% renewable electricity by 2022; other commercial buildings of 50,000 square feet and larger will be required to use 100% renewable electricity by 2030. By 2030 emissions will be reduced by over 317,000 metric tonnes.

The new clean electricity requirement will be the first in the nation and will reduce emissions from the City’s largest commercial buildings and accelerate San Francisco’s drive towards 100% renewable electricity by 2030.

Mayor London Breed also announced that she is directing the Department of the Environment to convene a public-private task force to examine how best to electrify San Francisco’s buildings (existing and new). The task force is expected to produce a decarbonization roadmap for buildings.

Goal: Commercial Building Electrification:
Reduce CO2 and other GHG emissions by requiring electricity used in commercial buildings to be renewably generated

Measurement: Annual decrease in CO2e emissions between 2022 and 2030 in large commercial buildings

Time to Implement: Phased implementation:

– Bldgs over 500,000 sqft by 2022
– 250,000 to 500,000 sqft by 2024
– 50,000 to 250,000 sqft by 2030.
