In 2022, the City of San Diego signed on to the Better Climate Challenge, committing to a 50% reduction in GHG emissions by 2030. The City of San Diego's new Climate Action Plan establishes a community-wide goal of net zero by 2035, committing San Diego to an accelerated trajectory for greenhouse gas reductions. The city’s portfolio consists of over 740 public facilities and the Climate Action Plan's strategies include 100 percent renewable electricity; water and energy efficiency; zero waste; bicycling, walking, transit and land use; and resiliency measures. 

As a Better Buildings Challenge Partner, the City will meet its energy efficiency goals in part by building on work completed through the Energy Efficiency and Conservation Block Grant (EECBG) program. Through EECBG, the City has made boiler upgrades to its Administration Building complex, implemented city gym lighting improvements, and completed broad-spectrum street lighting retrofit projects, all of which is expected to save about 18 million kilowatt-hours annually. Moving forward, the City will implement measures including but not limited to sustainable policies and provisions, completing retrofits and retro-commissioning, installing renewable energy, and conducting various education and outreach activities.
