For more than 100 million years<\/a>, trees have dropped their leaves every fall, creating a protective layer of duff that provides cover<\/a> for snails, bees, and butterflies. Decaying leaves fertilized the soil and gave nutrients<\/a> back to the trees. Today, fallen leaves still provide a harvest festival of benefits<\/a> \u2014 unless they get blasted into oblivion with a leaf blower.<\/p>\n\n\n\n

Across the United States, some 11 million<\/a> leaf blowers roar into action every year, obliterating delicate debris with 200-mile-per-hour winds. Their distinctive, whining drone has been hard to escape. But restrictions on leaf blowers have been spreading across the country, permitting some lucky locales to experience the season as nature intended, at a humane decibel level. <\/p>\n\n\n\n

Outright bans on the gas-powered machines have recently taken effect in Washington, D.C.<\/a>; Miami Beach<\/a>, Florida; and Evanston<\/a>, Illinois. California will end the sale of gas-powered blowers next summer. Their hum will also be silenced in Portland<\/a> and Seattle<\/a> in the coming years. Barring a sudden acceptance of lawns scattered with leaves, rakes and battery-powered devices will slowly replace them.\u00a0<\/p>\n\n\n\n

Long the dream of noise-sensitive people everywhere, bans started taking off after pandemic lockdowns in 2020 forced office workers into their homes. Stuck in their neighborhoods all day, people discovered the beauty of birdsong<\/a>, along with a newfound loathing for the whine of the leaf blowers.\u00a0<\/p>\n\n\n\n

Communities that had tried and failed to get restrictions on the devices are now starting to see success, said Jamie Banks, the co-founder and president of Quiet Communities, a nonprofit dedicated to reducing noise pollution: \u201cThere’s a lot more consensus around doing something about it.\u201d Today, more than 200 towns across the United States have restrictions on leaf blowers in place, though many just put limits on what hours or times of year people can operate them. <\/p>\n\n\n\n

Another factor behind the spread of bans is research showing that leaf blowers emit a shocking amount of air pollution. The California Air Resources Board<\/a> has estimated that operating a gas-powered leaf blower for an hour emits as much smog-forming polluting as driving a Toyota Camry from Los Angeles to Denver. How is that even possible? Many leaf blowers use a wildly inefficient \u201ctwo-stroke\u201d engine, which mixes oil and gasoline and spits out as much as a third<\/a> of that fuel as unburned aerosol. The outdated design is cheap, powerful, and really loud and dirty<\/a>.<\/p>\n\n\n\n

\u201cI definitely think people underestimate the risks,\u201d said Michael Brauer, a professor of public health at the University of British Columbia. <\/p>\n\n\n\n

A study<\/a> in 2015 found that lawn mowers, trimmers, leaf blowers, and other lawn equipment accounted for a quarter of all emissions of cancer-causing benzene in 2011, the most data available. They also accounted for 17 percent of volatile organic compounds and 12 percent of nitrogen oxides, the primary pollutants<\/a> of smog, and were responsible for 20 million tons<\/a> of planet-warming carbon dioxide emissions \u2014 about 4 percent<\/a> of what passenger cars emitted in 2011.<\/p>\n\n\n\n

\u201cThe big picture is that cars have gotten cleaner and cleaner and cleaner and cleaner, and this kind of equipment has not,\u201d Brauer said. \u201cAnd so this has become evident as a more important source of pollution.\u201d Because vehicle regulations have become so strict in California, for example, small, off-road engines like those found in leaf blowers emit more smog-producing emissions than all the 14 million passenger cars<\/a> in the state. <\/p>\n\n\n\n

Even their noise poses a health concern. Gasoline-powered leaf blowers operate at a low frequency, allowing the noise to carry over long distances and penetrate through walls. \u201cPeople can’t get away from the sound,\u201d Banks said. \u201cSo you go in your house, you close your windows, you shut your doors, and you can still hear it.\u201d <\/p>\n\n\n\n

A study<\/a> conducted by Banks and the EPA in 2017 found that commonly used lawn equipment was louder than the World Health Organization\u2019s recommended limit of 55 decibels up to 800 feet away. And every 5-decibel increase in the average daily noise level around people\u2019s home leads to a 34 percent increase in heart attacks and strokes, according to Harvard research<\/a> in 2020.<\/p>\n\n\n\n

So why did such a dangerous device take off in the first place? The first leaf blower-like machines, invented in the late 1940s, weren\u2019t intended to blow leaves \u2014 they were backpack crop dusters<\/a>, meant for spraying pesticides. Then someone had the brilliant idea of removing the chemical canister so that all the machine could do was blast away debris. The invention coincided with the development of the suburbs after World War II, when having a carpet of grass around your home became part of the American dream<\/a>. Fallen leaves were seen as a nuisance that needed removing: They covered up the green lawns everyone wanted to show off and turned sidewalks slippery in the rain. <\/p>\n\n\n\n

So in the 1970s, the Japanese company that had invented the crop duster, Kyoritsu Noki, started selling what the people wanted. Lawn care ballooned into a huge industry, and the backlash soon followed: As early as 1975, Carmel, California, banned the machines outright; by 1999, 20 cities in California<\/a> had outlawed them, though it took a while for the trend to start spreading to the rest of the country. <\/p>\n\n\n\n

Those bans then set off their own backlash. In 1998, a ban on leaf blowers in Los Angeles neighborhoods sparked a protest<\/a>, where gardeners, many of them recent immigrants, staged a hunger strike in front of City Hall arguing that the ban was a severe blow to their jobs. Today, the fight to save gas-powered leaf blowers has gotten more organized. In May, Georgia\u2019s Republican Governor Brian Kemp signed a law<\/a> prohibiting local governments from regulating gas-powered leaf blowers differently from battery-powered ones. It mirrors laws in dozens of states<\/a> that prevent cities from restricting natural gas hookups in new buildings.<\/p>\n\n\n\n

To be sure, swapping gas for electric blowers isn\u2019t as simple as it might sound. Landscapers have adopted a business model that allows them to go from house to house quickly \u2014 a job that can drain batteries fast, meaning that some workers need to be swapping batteries out<\/a> two or three times a shift. \u201cIt’s going to take more time for them to do the same job,\u201d Banks said. \u201cSo either the customer pays for that extra time, or they relax their aesthetic expectations and say, \u201cOK, just do a cursory cleanup, but we can live with leaves on the ground.\u201d And electric lawn tools still have a long way to go: In California, even with all the bans on gas-powered tools, they make up about 6 percent<\/a> of the equipment used by lawn care workers.<\/p>\n\n\n\n

While battery-powered versions are typically cheaper<\/a> than gasoline ones, buying new equipment to comply with bans is expensive for landscapers. Some local governments that have adopted bans on gas-powered blowers have also tried to help offset the costs of switching: Ahead of the 2024 ban on the sale of gas-powered leaf blowers, California has set aside $27 million<\/a> for small landscaping businesses to buy electric equipment; Washington, D.C. introduced a rebate program<\/a> for the same purpose.<\/p>\n\n\n\n

It\u2019s worth noting that the status quo comes at a price for lawn workers, too: They\u2019re subject to the worst of the air and noise pollution from the equipment they\u2019re wielding. \u201cIt’s as though you\u2019re sucking the exhaust out of the tailpipe of a car,\u201d Brauer said. \u201cThat’s sort of what you’re doing if you’re using a leaf blower.\u201d<\/p>\n
