Lawn care in the United States contributes significantly to pollution. With over 40 million acres of lawn in the country, the energy required to maintain these spaces is immense. Gas-powered lawn equipment, such as mowers, leaf blowers, and trimmers, emit high levels of air pollution, comparable to that of cars and trucks. The pollution from this equipment includes nitrogen oxides, hydrocarbons, carbon monoxide, and carbon dioxide, all of which contribute to climate change. In addition to air pollution, the use of fertilizers and pesticides in lawn care can result in nutrient enrichment of water bodies, known as eutrophication, further polluting rivers and waterways. While lawns have the potential to capture carbon, the emissions required for their maintenance may offset this benefit. To reduce the environmental impact of lawn care, Americans can adopt eco-friendly practices, such as using electric lawn equipment, reducing mowing frequency, and minimizing fertilizer use.

Gas-powered lawn mowers emit high levels of carbon dioxide and other pollutants
The impact of gas-powered lawn mowers on air quality is significant. Using a gas-powered mower for an hour can generate as many volatile organic compounds as driving a car for 300-350 miles. The EPA found that gasoline-powered lawn mowers emit eight times more nitrogen oxides, 3,300 times more hydrocarbons, 5,000 times more carbon monoxide, and more than twice the carbon dioxide per hour of operation than electric lawn mowers. These emissions contribute to climate change and have negative effects on human health and the environment.
In addition to the direct emissions from gas-powered lawn mowers, there are also indirect environmental impacts associated with their use. For example, the EPA estimates that 17 million gallons of gas are spilled each year while refilling lawn mowers, leading to soil and water pollution. The small engines that power these mowers contribute to noise pollution, which can be detrimental to both users and bystanders.
The use of gas-powered lawn mowers has come under increasing scrutiny due to the availability of more environmentally friendly alternatives. Electric lawn mowers, for instance, have improved in performance and battery life, offering a viable option for those seeking to reduce their carbon footprint. While electric mowers typically have a higher upfront cost, their lower maintenance requirements and reduced environmental impact make them a more sustainable choice over time.
To address the environmental and health concerns associated with gas-powered lawn care equipment, many states and municipalities are taking action. Rebates are being offered to encourage the adoption of battery-powered alternatives, and almost 100 cities across the U.S. have banned or limited the use of gas-powered equipment. These efforts reflect a growing awareness of the impact of lawn care on the environment and a shift towards more sustainable practices.

Electric lawn mowers are a more environmentally-friendly alternative
Lawn care is a major source of US air pollution. The US lawn care industry is sizeable, with Americans spending about $76 billion a year on their yards. The country has about 40 million acres of lawn, with turfgrass covering 1.9% of the US, including 700,000 athletic fields and 14,500 golf courses. Lawn equipment with small engines, such as lawnmowers and leaf blowers, emit more air pollution than most cars and trucks. Gas-powered lawn mowers emit eight times more nitrogen oxides, 3,300 times more hydrocarbons, 5,000 times more carbon monoxide, and more than twice the CO2 per hour of operation than electric lawn mowers. Using a gas-powered mower for an hour generates as many volatile organic compounds as driving a car for 300-350 miles.
In addition to reducing air pollution, electric lawn care equipment can also help alleviate noise pollution. One in five Americans ranks lawn care as their most despised chore, in part due to the ear-damaging noise produced by gas-powered equipment. To promote the use of electric lawn care equipment, many states and municipalities offer rebates on battery-powered lawn equipment, and more people are making the switch. Local governments can also encourage eco-friendly lawn care by becoming AGZA Certified Green Zones and reevaluating code requirements for specific lawn care, such as grass height restrictions, which can hinder the adoption of more eco-friendly yards.
While lawn care can have a significant environmental impact, lawns can also act as a weapon against climate change. Dr Carly Ziter found that the typical American lawn is more effective at capturing carbon than the untouched environment. However, the effectiveness of carbon-capturing soil could be offset by the emissions required to maintain it. Therefore, it is essential to maximise the positive qualities of lawns and reduce the negatives, such as by transitioning to electric lawn care equipment.

Lawn chemicals can cause harm to wildlife and human health
Lawn care is a significant aspect of American culture, with Americans spending about $76 billion annually on their yards. However, the chemicals used in lawn care can have detrimental effects on both wildlife and human health.
The US Fish and Wildlife Service reports that Americans use ten times more chemical pesticides on their lawns than farmers use on their crops. These pesticides are designed to kill pests, and most are broad-spectrum biocides, meaning they are toxic to a wide range of organisms, including insects, plants, wildlife, pets, and humans. In fact, 19 out of 30 commonly used lawn pesticides are linked to cancer or carcinogenicity, with glyphosate, an ingredient in Roundup, being a well-known example. Other health risks associated with these pesticides include birth defects, reproductive issues, liver or kidney damage, neurotoxicity, and endocrine disruption. The EPA has identified neurological conditions, immuno-response deficiencies, and birth defects as additional adverse effects of these pesticides.
The impact of these chemicals on pollinators is particularly concerning. Bees, for instance, are highly vulnerable to certain insecticides, which can disrupt their learning, navigation, and immune systems, leading to population decline. Other chemicals, such as aryl triazinones and acetolactate synthase inhibitors, can destroy the plants that pollinators like caterpillars of butterflies and moths rely on for food and egg-laying, severely disrupting their life cycles. The phenomenon of bioaccumulation and biomagnification further exacerbates the issue, as chemicals are passed down from prey to predator, intensifying their effects as they move up the food chain.
The widespread use of lawn chemicals also significantly impacts local biodiversity. By eliminating crucial species within an ecosystem, these chemicals disrupt ecological balance and stability. Additionally, lawn chemicals can contaminate water sources. Pesticides and fertilizers can leach into private and public wells and water supplies, and certain chemicals have been detected in groundwater. This contamination poses risks to aquatic life, with chemicals harming fish and other vital aquatic organisms.
To mitigate these risks, it is essential to opt for less toxic alternatives when using pesticides. Many least-toxic pesticides are organic botanicals, essential oils, or derived from other plant or natural mineral sources. Natural lawn care practices, such as using corn gluten as a natural weed killer and fertilizer, can effectively create a healthy and pest-free lawn. Additionally, electric lawn equipment can be used instead of gas-powered tools, reducing air pollution associated with lawn maintenance.

Fertilizer and pesticide use is deadly and costly
Fertilizer and pesticide use has a significant impact on the environment and human health, and it comes at a cost. Firstly, the production and use of synthetic fertilizers and pesticides contribute to pollution. For example, gas-powered lawnmowers used for lawn care are a source of air pollution, emitting volatile organic compounds that contribute to climate change. In fact, using a gas-powered mower for an hour can generate as many pollutants as driving a car for 350 miles, according to Scientific American. This form of pollution is not limited to air quality; waterways are also affected by toxic chemicals from fertilizer and pesticide runoff. The U.S. Environmental Protection Agency (EPA) has reported that this runoff can contaminate lakes, streams, and rivers, harming aquatic life.
The chemicals in fertilizers and pesticides also pose risks to human health. They have been linked to various types of cancer, neurological issues, immune system deficiencies, and birth defects. For instance, glyphosate, a common synthetic weed-killing ingredient, has been implicated in cancer cases, leading to costly lawsuits against manufacturers like Monsanto. These health risks are not limited to humans; pets and wildlife are also vulnerable to the toxic effects of these chemicals.
The financial implications of fertilizer and pesticide use are also significant. Lawnmower maintenance and fuel contribute to the overall cost of lawn care, which amounts to about $76 billion annually in the United States. In addition, the environmental and health costs associated with pollution and toxic chemical exposure can be substantial.
To mitigate these issues, Americans can adopt more sustainable lawn care practices. This includes reducing the use of chemical fertilizers and pesticides, opting for electric lawn care equipment, and embracing more diverse and natural lawns that require less maintenance and water. By prioritizing the health of the soil and the overall ecosystem, individuals can play a crucial role in combating climate change and creating a safer, more sustainable environment for all.
