What You'll Learn
Gas mowers emit as much pollution as cars
Gas-powered lawn mowers are a significant contributor to climate change. Despite their small size, gas-powered lawn mowers emit a significant amount of pollution. According to the U.S. Environmental Protection Agency (EPA), gas-powered lawn mowers are a public nuisance. Using a gas-powered lawn mower for an hour generates as many volatile organic compounds (VOCs)—dangerous airborne pollutants that exacerbate human respiratory and cardiovascular problems—as driving a typical car for 300 to 350 miles. The EPA estimates that with 54 million Americans mowing their lawns weekly, gas lawn mower emissions account for as much as 5% of the nation's total air pollution.
The EPA further reports that off-road gasoline-powered equipment, such as lawn mowers and leaf blowers, emit approximately 242 million tons of pollutants annually, comparable to the emissions from cars and homes. Nationally, this equipment accounts for 17% of all VOC emissions, 12% of NOx emissions, 29% of CO emissions, 4% of CO2 emissions, and 2-5% of particulates.
To put it into perspective, a push mower will produce the same HC+NOx in an hour as a car driven 257 miles, and the same CO as one driven 401 miles. Under tighter federal emissions standards for lawn mowers, a push mower may produce as much HC+NOx as a car driven 160 miles, meaning one lawn mower equals four cars in terms of emissions.
Switching to electric lawn care equipment is a more environmentally friendly option. Electric mowers create no exhaust emissions and run much cleaner, needing less maintenance and being easier to use. They are also cheaper to run, using about as much electricity as an ordinary toaster, with most owners spending around $5 a year on electricity. While electric mowers are more expensive upfront, they save money in the long term on maintenance, oil, and other costs associated with gas mowers.

Gas mowers produce volatile organic compounds
Gas-powered lawn mowers emit a significant amount of pollution and are a public nuisance. They produce volatile organic compounds (VOCs) and other emissions, which contribute to air pollution and can exacerbate human respiratory and cardiovascular problems.
According to the U.S. Environmental Protection Agency (EPA), gas-powered lawn mowers generate as many volatile organic compounds in an hour as driving a typical car for 350 miles. This equates to approximately 242 million tons of pollutants annually, accounting for 17% of all VOC emissions in the United States. Additionally, the EPA estimates that Americans spill around 17 million gallons of gasoline each year just from refuelling their lawn mowers, leading to soil pollution and degradation.
Other sources claim that running a gas-powered lawn mower for an hour can produce as much air pollution as driving a car between 20 and 300 miles, or even as much as 40 new automobiles running for an hour. This is because gas mowers are very inefficient, and despite their small size, they produce a lot of air pollution.
As a result, battery-powered or electric lawn mowers are recommended as a more environmentally friendly alternative. They produce no exhaust emissions and are more efficient, with lower noise levels and less maintenance required. However, it is important to note that the environmental benefits of electric mowers depend on the energy sources used to charge them.

Gas mowers are a public nuisance
Gas-powered lawn mowers are a significant contributor to climate change. Despite their small size, they emit a substantial amount of pollution and are a public nuisance. According to the U.S. Environmental Protection Agency (EPA), traditional gas-powered lawn mowers generate dangerous volatile organic compounds (VOCs), which are harmful airborne pollutants that exacerbate human respiratory and cardiovascular issues. The EPA estimates that with 54 million Americans mowing their lawns weekly, gas lawn mower emissions account for about 5% of the nation's air pollution, comparable to the emissions of two million cars.
The inefficiency of gas-powered lawn mowers contributes to their high pollution levels. A typical 3.5-horsepower gas mower emits the same amount of VOCs, nitrogen oxides, and carbon monoxide in an hour as a new car driven for 550 kilometers. This is due to the mower's small engine size and incomplete combustion of fuel. Older gas mowers are even worse, with one hour of use resulting in as much pollution as driving a car for 200 to 350 miles, or even burning a tire.
The environmental impact of gas mowers extends beyond air pollution. The EPA estimates that 17 million gallons of gasoline are spilled each year while refuelling lawn equipment, leading to soil pollution and degradation. Additionally, gas-powered equipment is extremely noisy, with noise levels exceeding 100 decibels, which is detrimental to the health of humans, pets, and wildlife. Hearing loss can occur at noise levels of around 90 decibels, highlighting the excessive noise pollution created by gas mowers.
The drawbacks of gas mowers have prompted a shift towards electric alternatives. Electric mowers are more environmentally friendly, producing no exhaust emissions and requiring less maintenance. They are also cheaper to operate, costing about $5 per year in electricity. While electric mowers have a higher upfront cost, they offer long-term savings by eliminating the need for oil changes and filter cleanings. Additionally, electric mowers are more convenient, with push-button starters and smaller sizes, making them easier to use and store.
However, it is important to acknowledge that electric mowers are not a perfect solution. Their runtime is limited, typically lasting only 30 to 60 minutes on a single charge, which may not be sufficient for large lawns or commercial use. Additionally, the environmental benefits of electric mowers are diminished if they are charged using electricity generated from coal-fired power plants, a significant source of greenhouse gas emissions. Nonetheless, when powered by clean and renewable energy sources, electric mowers offer a greener and more sustainable alternative to gas-powered equipment.

Frequently asked questions
A gas mower emits about 48 kilograms (106 lbs) of greenhouse gas in one season. In an hour, a gas mower can produce as much air pollution as driving a car 20 to 550 kilometres.
Electric mowers create no exhaust emissions and run much cleaner than gas mowers. They are also cheaper to run, using about as much electricity as an ordinary toaster, and require less maintenance.
Electric mowers tend to cost up to $150 more than gas mowers, and the plug-in varieties can only go 100 feet from the closest outlet without an extension cord. Cordless models last only 30-60 minutes on a charge, which may not be sufficient for landscaping beyond the average lawn.
Beyond switching to electric mowers, consider reducing the size of your lawn. Lawns are poor carbon sinks because most grass has a relatively shallow root system. That means that areas that could be covered with trees or larger plants, which trap carbon and help the environment, are now covered with grass which does not sequester carbon well.
