Why the Bay Area’s Zero-Emission Appliance Rule is a Big Deal

BAAQMD’s trailblazing rule will ban the sale of latest gas furnaces and water heaters to combat nitrogen oxide pollution. It marks an enormous victory for public health and the planet.

Air quality officials within the San Francisco Bay Area just made history by moving to adopt the nation’s first rules phasing out latest gas-fueled water heaters and furnaces in homes and businesses inside about eight years. This motion serves as a serious step in the hassle to curb health-harming and planet-warming emissions from buildings.

Several cities in California, including Los Angeles and within the Bay Area, have outlawed latest gas hookups, but these are the primary regulations that might effectively ban the sale of gas appliances. Research shows that halting the burning of fossil fuels in homes and businesses is helpful for the health of residents and vital to combat climate change. It should thus be replicated throughout the state and nation. A policy transient published by the Emmett Institute in March 2022 outlines California air districts’ legal authority to adopt these sorts of regulations and suggests policy mechanisms to assist make sure the transition to electric appliances is equitable and reasonably priced.

The Threats of Gas Appliances

Day-after-day, domestic gas-powered constructing appliances emit 65 tons of toxic and highly reactive gases called nitrogen oxides (NOx) per day. That’s over 4 times as much as all the gas power plants within the state combined. These chemicals can irritate airways and exacerbate respiratory diseases, in line with the Bay Area Air Quality Management District (BAAQMD). Moreover, NOx react with other chemicals within the air to create other harmful pollutants, like fantastic particulate matter and ozone.

Gas stoves are a significant driver of childhood asthma, leaking methane even while turned off and releasing as much nationwide climate pollution every year as 500,000 cars. Furnaces and water heaters are even greater polluters, with major contributions to outdoor air pollution within the Bay Area. In line with experts at think-tank Rocky Mountain Institute (RMI), these appliances release “nearly 3 times as much smog-causing [NOx] pollution as all the cars within the region, and 7 times as much as all the region’s power plants.” In addition they produce many of the climate pollution that derives from fuel combustion in buildings.

There have been recent revelations in regards to the dangers of gas appliances, including research by RMI, the UCLA Fielding School of Public Health, Harvard T.H. Chan School of Public Health, and Stanford University, amongst others. It’s now evident that gas appliances not only pose substantial risks to residents’ health, but additionally obstruct efforts in California, in america, and the world over to “secure a protected climate future.”

The Rule and Other Potential Developments

By adopting this rule, BAAQMD is exercising its legal authority under each federal and state law to control nitrogen oxides. The rule would ban most latest gas water heaters (in latest construction and replacements in homes) after 2027, gas furnaces after 2029, and enormous gas water heaters (in apartments and business buildings) after 2031. The phaseout would apply throughout the air district’s territory and is anticipated to chop greater than 3,000 tons of NOx emissions every year. Additionally it is projected to forestall 85 early deaths, hundreds of asthma attacks, and lost school and workdays annually, with the best advantages to low-income communities and communities of color which are hardest hit by air pollution.

The foundations don’t apply to other appliances, like gas stoves or clothes dryers, which release far less pollution than water heaters and furnaces. Richard Trumka Jr., a member of the Consumer Product Safety Commission (CPSC), ignited debate around banning gas-burning stoves when he raised it as an option to deal with the risks of gas appliances. Although the CPSC clarified that a ban was not within the works, the agency voted earlier this month to hunt public input on the hazards of gas stoves. Such a Request for Information might be a possible first step toward implementing safety standards or other regulations governing their use.

Meanwhile, the California Air Resources Board adopted plans last 12 months to phase out gas water heaters and furnaces statewide by 2030 but is not going to consider setting regulations to accomplish that until 2025. Within the Los Angeles Basin, where ozone pollution is the worst within the nation, the South Coast Air Quality Management District can also be years behind. Regulators there and beyond are watching the Bay Area closely.

 Obstacles Related to the Rule

While this rule could have great advantages for the climate and health, it shouldn’t be without controversy. Several hundred speakers attended BAAQMD’s hearing each in-person and on Zoom to deliver public comment after public comment, much of it in support. Speakers representing the California Air Resources Board and quite a lot of public health and environmental advocacy groups cheered the proposal.

Businesses, manufacturers, and the development industry have requested delays and other changes to the principles and query the feasibility of the phaseout given the limited availability of warmth pumps and wiring in addition to air flow requirements that complicate installations in older homes. Nevertheless, the proposal includes 4 to eight years of lead time for every of the rule components before it begins to take effect. The foundations will send a very important signal to contractors and manufacturers regarding the demand, while providing them time to construct capability.

Opponents also argue it might place a big financial burden on many households that would not afford it. There are serious equity barriers around constructing electrification that elected officials within the Bay Area, Southern California, and other parts of the state could have to work hard to deal with with the intention to make sure the transition is successful.

The most important obstacle is up-front cost; electric appliances still cost greater than gas ones. In line with BAAQMD, installing a latest heat pump costs about $2,900 greater than a gas furnace, and a heat-pump water heater costs a median of $850 greater than a gas one. Nevertheless, they might be offset by cost savings, including reduced tax credits and utility bills, rebates, and other federal climate incentives which are becoming available under the federal Inflation Reduction Act, along with state programs designed for low-income households. An evaluation by SPUR, a nonprofit public policy organization, found that replacing gas furnaces and water heaters with heat pumps could actually end in $8,000 in cost savings with existing state and federal subsidies.

Now that the principles have passed, the air officials will initiate a stakeholder working group to be certain that market actors are creating the conditions mandatory for equitable and reasonably priced implementation by the planned dates. Two years before the principles take effect, staff may also evaluate market readiness and whether equitable implementation is possible, and adjust accordingly. These safeguards will help be certain that low-income households will indeed reap the advantages of clean-fueled appliances.


With its rule adoption, the Bay Area is leading the state on environmental innovation. It is crucial for California and air districts throughout the state to follow suit and swiftly address the harms from gas appliances. A switch to zero-emitting heat pumps from gas appliances in California would end in 350 fewer deaths and 900 fewer cases of respiratory illnesses, while saving $3.5 billion in health costs per 12 months. This transition is not going to occur overnight. Appliances can last for a minimum of 20 years, and it should take a long time for the Bay Area’s 1.8 million households that currently use gas-fueled appliances to modify them out. However the Bay Area’s groundbreaking rule marks a major move in the precise direction.
