    What's the deal with California and natural gas in buildings? It started with cities and counties requiring new construction projects to be all-electric. On Sept. 22, 2022, California policymakers voted unanimously to ban the sale of gas furnaces and water heaters after 2030. What's with all these restrictions, and why now?

    Over the last few years, California legislators have set increasingly aggressive greenhouse gas (GHG) reduction goals. Perhaps the most aggressive legislation is SB 100, the California 100% Clean Energy Act, signed into law by Jerry Brown on Aug. 29, 2018. SB 100 sets the goal of 100 percent carbon-free electricity by 2045. The state is aiming for emissions reductions across the board at the same time.

    To help meet this goal, researchers have categorized the state's leading sources of greenhouse gas emissions by sector. Most people would not be surprised to learn that transportation is the largest single source, responsible for roughly 40 percent of GHG emissions in the state. What may come as a surprise is that burning natural gas to heat buildings and water accounts for nearly 10 percent of GHG emissions in California.
