What You'll Learn
Gas-powered mowers produce a lot of air pollution
Gasoline-powered lawn mowers emit about 48 kilograms (106 lbs) of greenhouse gas in one season. They emit high levels of carbon monoxide, volatile organic compounds, and nitrogen oxides, producing up to 5% of the nation's air pollution and more in metropolitan areas. The California Environmental Protection Agency, Air Resources Board, found that operating a commercial lawn mower for an hour emits as much pollution as driving a Toyota Camry about 300 miles.
The process of mowing lawns also produces other types of pollution. For example, lawn clippings are often sent to landfills, where they decompose anaerobically and produce methane, a greenhouse gas that is 21 times more potent than CO2. Additionally, empty containers of lawn chemicals are transported to landfills, contributing even more CO2 to the environment. Even refilling lawn mowers damages the environment, with an estimated 17 million gallons of gas spilled annually during refills.
To reduce air pollution, homeowners can switch to electric lawn mowers, which produce no emissions and are lower maintenance, easier to store, and quieter than gas-powered mowers. While electric mowers may be more expensive upfront, the cost evens out over time due to fuel and maintenance savings. If an electric mower is not accessible, people can reduce the frequency of mowing or opt for manual push reel mowers.

Electric mowers produce zero emissions
The lawn care industry in America is huge, and lawn equipment, such as gas-powered leaf blowers and lawn mowers, is a significant source of pollution. Gas-powered lawn mowers contribute to air pollution and greenhouse gas emissions, with their two-stroke or four-stroke engines requiring about 800 million gallons of gasoline annually. In addition, two-stroke engines pose a unique environmental hazard as they lack an independent lubricant system, meaning fuel and oil are mixed, and about 30% of the fuel does not combust completely, releasing toxic gases.
Electric mowers, on the other hand, produce zero emissions at the point of use. They are a much more environmentally friendly option, removing the need for gasoline and the associated risks of handling volatile fuels. Electric mowers are safer for both users and the environment. They are more energy-efficient than their gas-powered counterparts, resulting in lower overall energy consumption during operation.
The U.S. Environmental Protection Agency (EPA) has found that operating a new gasoline lawnmower for one hour emits as many volatile organic compounds and nitrogen oxides as driving a new car for 45 miles. This highlights the substantial pollution generated by gas mowers. By switching to electric mowers, Americans can take a proactive step towards a greener future, reducing emissions, cutting energy use, and lowering their carbon footprint.
While electric mowers were once overlooked due to their higher cost and limited battery life, more affordable and long-lasting options are now available. Although they may be more expensive on average, the cost evens out over time due to reduced fuel and maintenance requirements. Electric mowers are also lower maintenance and easier to store, and modern options are cordless.
Overall, electric mowers are a promising alternative to traditional gas-powered models, offering zero emissions and a range of other environmental and practical benefits.

Gasoline mowers cause noise pollution
Gas-powered lawn mowers have long been popular among homeowners who want to keep their lawns neat and tidy. However, these machines come at an often-overlooked environmental cost. Gasoline mowers emit harmful gases and particles that contribute to air pollution and climate change. According to a study by Quiet Communities, lawn care equipment was responsible for releasing 26.7 million tons of pollutants in 2011. Gas-powered lawn mowers make up five per cent of total air pollution in the United States, with this figure being even higher in urban areas.
In addition to air pollution, gasoline mowers also cause noise pollution, which can disrupt wildlife and ecosystems. Recognizing the environmental impact of gasoline mowers, California will become the first state to ban the sale of new gasoline-powered lawn mowers and other landscaping tools in 2024. The ban aims to reduce emissions from small off-road engines, which are more polluting than all the cars in the state combined.
Homeowners can opt for more sustainable alternatives to gasoline mowers, such as electric, reel, or robotic mowers. Electric mowers are a quieter and more environmentally friendly option, emitting no pollutants. They are also low maintenance, easy to store, and can be plugged in and used immediately. Although electric mowers tend to be more expensive, the cost evens out over time due to reduced fuel and maintenance expenses. Reel mowers, which require no fuel or electricity and produce no emissions, are another option, but they demand more physical effort and may not be practical for larger lawns. Robotic mowers, a newer technology, offer an eco-friendly and convenient choice, as they use rechargeable batteries, produce no emissions or noise pollution, and help maintain a consistent grass height, reducing the need for fertilizers and pesticides.
To reduce the environmental impact of lawn care, people can also make smaller adjustments to their mowing habits, such as mowing less frequently. Additionally, choosing landscaping that minimizes the need for mowing, such as native shrubs and edibles, can create attractive and productive lawns while reducing the use of gasoline mowers. By adopting these sustainable alternatives and practices, homeowners can play a significant role in combating climate change and preserving the environment.

Lawn care produces 13 billion pounds of toxic pollutants annually
Lawn care is a major contributor to climate change, with the typical American lawn care routine producing 13 billion pounds of toxic pollutants annually. The process of mowing lawns produces a large amount of carbon dioxide (CO2) and other greenhouse gases, as well as air pollutants. According to the Environmental Protection Agency (EPA), a gas-powered lawn mower emits 89 pounds of CO2 and 34 pounds of other pollutants per year. In addition, the EPA estimates that hour-for-hour, gas-powered lawn mowers produce 11 times as much pollution as a new car.
The inefficiency of gas-powered lawn mowers means that despite their small size, they produce a significant amount of air pollution. Running an older gas-powered lawn mower for an hour can produce as much air pollution as driving a new car 550 kilometers. Gas-powered lawn equipment also emits high levels of carbon monoxide, volatile organic compounds (VOCs), and nitrogen oxides, which contribute to smog formation.
The impact of lawn care on the environment extends beyond air pollution. Lawn fertilizers are often overused, with Americans estimated to use ten times more fertilizer on lawns per acre than on food crops. In 2004, Americans used 70 million pounds of fertilizers on their lawns, contributing to nutrient waste and water pollution when excess fertilizers are washed away.
Additionally, the transportation of grass clippings to landfills produces CO2 and other forms of air pollution. Grass clippings that decompose anaerobically in landfills produce methane, a greenhouse gas that is 21 times more potent than CO2. The EPA also found that gasoline-powered lawn mowers emit eight times more nitrogen oxides, 3,300 times more hydrocarbons, and 5,000 times more carbon monoxide than cars.
To reduce the environmental impact of lawn care, homeowners can opt for electric lawn mowers, which produce no emissions and have lower maintenance and storage costs. Electric mowers are also quieter, generating noise levels about 50% lower than their gas-powered counterparts. If an electric mower is not accessible, people can reduce the frequency of mowing or switch to environmentally friendly alternatives to traditional lawns.
