Four ways the initiative could affect Washington.

Burning gas to heat homes, generate electricity, and power industry bears responsibility for about a quarter of Washington's climate pollution. Washington State - and its cities-have enacted a suite of laws to help homes and businesses make the transition from gas to all-electric appliances such as heat pumps. Initiative Measure No. 2066 on Washington's November 2024 ballot would directly repeal some of the state's gas transition policies and could impact others.

Below we explain four policies and regulations in Washington that the initiative could impact.

1. Washington's 2021 Energy Code

Initiative 2066 reverses a requirement that Washington's energy code work toward emissions-free new construction by 2031 and prohibits the energy code from limiting gas in buildings. This change could affect Washington's latest energy code, which incentivizes electric heat pumps over gas appliances in new buildings.

Buildings make up a quarter of Washington's carbon emissions, polluting more than any other sector except transportation. Almost half of that pollution comes from burning fossil fuels, mostly gas, for space and water heating.

Fifteen years ago, Washington legislators recognized that constructing more and more buildings that burn fossil fuels would catapult the state's carbon pollution problem from bad to worse. In 2009 policymakers passed Senate Bill 5854, establishing new requirements for the state's energy code, which regulates the design and construction of new buildings. The law mandated that the energy code help achieve a statewide goal of constructing emissions-free homes and buildings by 2031.

In 2024 Washington's State Building Code Council (SBCC) finalized the state's latest residential and commercial energy code. In its initial draft of the 2021 code, SBCC required electric heat pumps in all new commercial and residential buildings. However, after the United States Court of Appeals for the Ninth Circuit overturned Berkeley, Califonia's prohibition on gas hookups in new buildings, SBCC voluntarily revised its draft code to bolster it against potential lawsuits from the gas industry.

Washington's final 2021 energy code does not require heat pumps or ban gas hookups, but it strongly incentivizes electric heat pumps. If builders choose to install a gas furnace or boiler, they will need to compensate with a slew of other (likely more expensive) efficiency measures. It's worth noting that building new all-electric homes is cheaper than building new homes that use both gas and electricity. Further, heat pumps can reduce people's energy bills and are a cooling solution as well as a heating one. Today nearly half of Washington homes lack air conditioning.

Initiative 2066 would repeal the state's longstanding requirement that the energy code work toward emissions-free new construction by 2031, and it would bar the code from "prohibiting, penalizing, or discouraging" gas appliances in buildings. This new prohibition might be used to challenge the 2021 energy code for incentivizing electric heat pumps over gas appliances.

Initiative 2066 strike-through: "The Washington state energy code shall be designed to: Construct increasingly energy efficient homes and buildings that help achieve the broader goal of building zero fossil-fuel greenhouse gas emission homes and buildings by the year 2031." Initiative 2066 addition: "The Washington state energy code may not in any way prohibit, penalize, or discourage the use of gas for any form of heating, or for uses related to any appliance or equipment, in any building."

2. Seattle's 2023 Building Emissions Performance Standard

Initiative 2066 prohibits cities and towns from actions that "prohibit, penalize, or discourage" the use of gas in buildings. This could affect Seattle's new Building Emissions Performance Standard, which requires large buildings to reach net zero emissions by 2050 - a goal that's difficult to achieve without transitio...
