Background Information:
It is no secret that Multnomah County residents breathe the dirtiest air in Oregon and face the highest risk of pollution-related cancer from air toxics. Air pollution disproportionately impacts low-income residents and people of color in City of Portland neighborhoods.
In November 2022, Multnomah County issued a report titled, “A Review of the Evidence: Public Health and Gas Stoves” and concluded that, “To protect against pollution-driven respiratory problems, we recommend a transition away from combusting appliances in favor of healthy electric alternatives whenever possible.” [source]
The Sierra Club then released a report in March 2024 alongside Verde, Oregon Physicians for Social Responsibility, Beyond Toxics, and RMI showing that methane gas appliances in Multnomah County release a cumulative 1,000 tons of nitrogen oxides (NOx) every year, the second-largest source of smog-forming air pollution after cars and trucks. The report calls on Multnomah County to establish air quality standards that will phase out NOx-emitting appliances over a reasonable period of time. There is a precedent for this: in 2023, San Francisco’s Bay Area Air Quality Management District decided to allow only zero-NOx appliances to be sold starting in 2027.
In addition to indoor appliances like furnaces, water heaters, and stoves, gas-powered leaf blowers also impair Portlanders’ quality of life, and their negative health impacts are felt by landscape workers, who are predominately people of color. Gas leaf blowers produce significant noise pollution that can lead to negative health outcomes such as stroke, high blood pressure, heart attack, tinnitus, and hearing impairment. Gas leaf blowers also emit significant amounts of air pollution. A recent study demonstrated that running a gas leaf blower for just one hour produces the same level of pollution as driving a midsize sedan 1,100 miles – the equivalent of a road trip from Portland to southern California.
In 2024, Portland City Council unanimously passed an ordinance to phase out the use of gas handheld or backpack leaf blowers on public and private property within Portland beginning in 2026, at which time the use of gas leaf blowers will still be allowed from October to December. A year-round prohibition will go into effect in 2028. The legislation will also offset costs for small businesses that experience a disproportionate hardship transitioning to electric leaf blowers.
