A new law in Seattle marks the latest in a wave of local efforts to electrify homes and other buildings. Under the city’s Building Emissions Performance Standard, signed into law last week, all existing commercial and multifamily residential buildings over 20,000 square feet will need to reach net-zero emissions by 2050. Meeting that target will effectively require building owners to replace oil and gas-powered furnaces, water heaters, gas stoves, and other appliances with electric alternatives like heat pumps and induction stoves. Buildings in Seattle generate 37 percent of the city’s total emissions, and the new law is expected to slash that number by more than a quarter.

Seattle’s ordinance reflects a growing push to eliminate the use of fossil fuels in buildings, which would reduce indoor air pollution and cut carbon emissions. But some other local electrification policies have hit a wall. In April, the 9th U.S. Circuit Court of Appeals struck down Berkeley, California’s first-in-the-nation ban on natural gas in new buildings. The ruling caused several cities across the 9th Circuit region, which spans 11 western states and territories including California, Oregon, and Washington, to suspend similar policies. Yet despite the setback, clean energy experts told Grist that governments still have plenty of options to electrify buildings. Cities and states like Seattle; Ashland, Oregon; and Washington state are sidestepping Berkeley’s legal challenges by finding creative alternatives to banning gas outright — including by setting emissions targets, updating building codes, and restricting indoor air pollution.

In 2019, Berkeley became the first city in the country to ban new buildings from connecting to natural gas lines. The California Restaurant Association quickly mobilized to file a lawsuit against the city for its policy, backed with more than $1 million in funding from SoCalGas, the nation’s largest gas distribution utility. In 2021, a federal district court ruled against the restaurant industry, but in April 2023, a panel of three judges on the 9th Circuit Court of Appeals overturned the lower court’s decision, shooting down Berkeley’s ordinance. The judges ruled that because national efficiency standards for appliances under the federal Energy Policy Conservation Act prevent cities and states from setting their own standards, local governments can’t ban infrastructure to prevent the use of fossil fuel-powered appliances. “The decision does not make a lot of sense legally,” Jan Hasselman, a senior attorney at Earthjustice, wrote at the time. Since the ruling, other cities in California, including Encinitas, Santa Cruz, and San Luis Obispo, have pulled back their own natural gas bans. Eugene, which was the first city in Oregon to adopt a natural gas ban modeling Berkeley’s, also suspended its ordinance in June. The Berkeley city attorney’s office has requested a rehearing of the case before 11 judges on the 9th Circuit, which could result in a new decision.

In the meantime, Hasselman told Grist that building emissions standards like the one passed in Seattle are one way for cities to dodge legal hurdles by avoiding an explicit ban on gas. The Seattle policy sets benchmarks that ramp up every five years for large buildings to reduce their greenhouse gas emissions, and lets building owners decide how they want to reach those standards. Theoretically, they could hold onto their oil and gas appliances, though Plummer pointed out that avoiding electrification will likely become more and more difficult over time. Commercial buildings covered under Seattle’s new law must reach net-zero emissions by 2045, and multi-family buildings by 2050 — a requirement that would effectively require swapping out fossil fuel appliances with heat pumps and other electric options. (Carbon offsets purchased by utilities would be allowed to count toward buildings’ net-zero calculations.) A handful of other cities have also passed building performance standards to cut emissions, including Boston, New York, and Washington, D.C.
