The San Francisco Bay Area is taking a major step towards improving air quality by phasing out natural gas-fueled water heaters and furnaces. The Bay Area Air Quality Management District (BAAQMD) recently approved new rules that seek to eliminate harmful nitrogen oxide (NOx) emissions from these appliances. The rules will ban the sale of NOx-emitting natural gas water heaters in 2027 and prohibit NOx-emitting furnaces in 2029, with large commercial water heaters following suit in 2031.

NOx emissions from building appliances are on par with those generated by passenger vehicles in the Bay Area, and exposure to particulate Pollution is linked to respiratory conditions, neurological disease, heart attack, stroke, lung cancer, and premature death. The BAAQMD estimates that the 1.8 million water heaters and furnaces in the Bay Area significantly impact air quality, resulting in dozens of early deaths and a wide range of health impacts, particularly in communities of color.
“This groundbreaking regulation will phase out the most polluting appliances in homes and businesses to protect Bay Area residents from the harmful air Pollution they cause,” said Philip Fine, executive officer of the Air District.
Notably, however, the rules will apply only to new appliances and do not include those used for cooking, such as gas stoves. Gas stoves have sparked heated debate over the past few months, particularly after a member of the federal Consumer Product Safety Commission floated the idea of stricter regulations or even a possible ban on these appliances. While the Commission has since clarified that they do not intend to ban gas stoves, they are requesting information from the public about any hazards connected to gas stoves.
While the new regulations may not address all natural gas appliances, they are a significant step towards improving air quality in the Bay Area. The BAAQMD estimates that the new amendments will improve regional air quality and reduce exposure to particulate matter while saving up to $890 million annually in Pollution-related health impacts. The amendments are expected to prevent an estimated 85 premature deaths and dozens of new asthma cases in the Bay Area each year.
In addition to protecting public health, the phaseout of natural gas appliances will also create new opportunities for renewable energy. The only zero-NOx appliances currently available are electric appliances, and transitioning to electric-powered appliances will create new demand for renewable energy sources.
This move by the San Francisco Bay Area is an important example of how local governments can take action to protect the environment and public health. As individuals, we can also take action by supporting policies that reduce our reliance on fossil fuels and promote renewable energy sources. We can also make small changes in our daily lives, such as using energy-efficient appliances and reducing our overall energy consumption. Together, we can work towards a more sustainable and healthy future for all.
