Avoid using gas-powered lawn equipment, especially on hot days
To avoid ozone pollution, it is important to avoid using gas-powered lawn equipment, especially on hot days. This is because gas-powered lawn equipment, such as lawnmowers, leaf blowers, trimmers, and chainsaws, emit large amounts of nitrogen oxides (NOx) and volatile organic compounds (VOCs). These gases are the essential raw ingredients needed to form ground-level ozone, which is a harmful air pollutant.
Nitrogen oxides are produced when fossil fuels like gasoline are burned, and VOCs are released into the air from common consumer products like paint and household chemicals. When these gases come into contact with sunlight, they react and form ozone smog. High levels of ozone are more likely to form in warmer temperatures, which is why it is especially important to avoid using gas-powered lawn equipment on hot days.
Ozone pollution can have negative impacts on human health, particularly for children, the elderly, and people with lung diseases such as asthma. It can also harm the environment. Therefore, it is crucial to take steps to reduce ozone pollution, such as avoiding the use of gas-powered lawn equipment.
There are alternative options available, such as electric lawn equipment, which do not produce the same levels of nitrogen oxides and VOCs as gas-powered equipment. Electric lawn equipment can be powered by batteries, which can be easily swapped out when needed. While some people may be concerned about the cost and efficiency of electric lawn equipment, the market is already shifting towards these more environmentally friendly options.
In some places, such as California and Colorado, there are even regulations and bans in place to restrict the use and sale of gas-powered lawn equipment. These efforts are part of a larger movement to reduce harmful pollutants and transition towards a carbon-free economy. By avoiding the use of gas-powered lawn equipment, especially on hot days, individuals can play a crucial role in reducing ozone pollution and improving air quality.

Limit outdoor activities when ozone levels are high
Ground-level ozone is an invisible, dangerous, and widespread pollutant in the United States. It is formed when gases from tailpipes, smokestacks, factories, and other sources react with sunlight. As a result, ozone levels tend to be higher on hot, sunny days in urban areas, although wind can carry it over long distances, affecting rural areas as well.
Ozone pollution is harmful to human health, especially for those with asthma, children, older adults, and people with lung diseases. The risk of harm increases with higher ozone levels, faster breathing due to exercise or work, and prolonged outdoor exposure.
To avoid the harmful effects of ozone pollution, it is advisable to limit outdoor activities when ozone levels are high. Here are some specific recommendations to consider:
- Stay indoors when possible: This is especially crucial for at-risk groups, including children, teenagers, older adults, and people with lung diseases like asthma, as well as those who work or exercise outdoors. Schools, childcare facilities, and employers should encourage indoor activities or schedule outdoor activities for mornings when ozone levels are typically lower.
- Adjust work and exercise schedules: If you must be outdoors, try to work or exercise in the mornings when ozone levels are generally lower. Take frequent breaks and consider discussing adjustments to your work schedule with your employer until air quality improves.
- Monitor air quality: Stay informed about air quality forecasts, which are often provided with weather forecasts. Utilize websites like airnow.gov or implement an Air Quality Flag Program to help you make informed decisions about outdoor activities.
- Suspend outdoor activities when necessary: Follow recommendations from health authorities, such as suspending outdoor activities and field trips for children when air quality is deemed unhealthy. Resume normal activities once the air quality improves.
- Take precautions during outdoor work: If your work demands physical exertion outdoors, consider adjusting your schedule or taking breaks to minimize exposure to high ozone levels. This is particularly important for those in occupations such as landscaping or construction, where outdoor work and strenuous activity overlap.

Reduce car trips and use public transportation
Ozone pollution, also known as smog, is a dangerous and widespread pollutant that is harmful to human health and the environment. It is caused by gases released from tailpipes, factories, and other sources, which react with sunlight to form ozone. As a result, ozone pollution levels tend to be higher during warmer temperatures. One of the most effective ways to reduce ozone pollution is to reduce car trips and use public transportation.
Reducing the number of car trips is a crucial step in lowering ozone pollution levels. This can be achieved by combining errands and planning trips in advance to minimise unnecessary journeys. When possible, consider walking, biking, or carpooling to your destination. Working from home, if feasible, can also help reduce the need for commuting by car.
Using public transportation instead of driving alone can significantly reduce ozone pollution. Switching from a solo car commute to public transportation can result in substantial reductions in carbon dioxide emissions. For example, an individual who switches from a 20-mile solo car commute to public transportation can reduce their annual carbon dioxide emissions by more than 48,000 pounds. This is equivalent to a 10% reduction in greenhouse gas emissions for a typical two-adult, two-car household.
Public transportation not only reduces emissions but also helps to decrease congestion. Research has shown that public transportation use saves time and reduces the overall congestion costs for urban areas. Additionally, it contributes to saving gasoline, with public transportation in the United States saving more than 11 million gallons of gasoline daily.
By reducing car trips and utilising public transportation, individuals can play a significant role in lowering ozone pollution levels. These actions directly contribute to decreasing emissions, improving air quality, and mitigating the harmful effects of ozone pollution on human health and the environment.

Conserve energy and electricity
Conserving energy and electricity is an important way to avoid ozone pollution. Ground-level ozone is a harmful air pollutant that is formed by chemical reactions between oxides of nitrogen (NOx) and volatile organic compounds (VOC). These reactions occur in the presence of sunlight and heat, and the resulting ozone is a key ingredient in "smog". As such, reducing energy consumption and conserving electricity can help to lower the occurrence of these chemical reactions.
One way to conserve energy is to reduce car usage. Cars are a significant source of NOx and VOC emissions, so opting for carpooling, public transportation, biking, or walking can significantly reduce energy consumption and lower ozone levels. Additionally, keeping car engines properly tuned, maintaining correct tyre pressure, and refuelling during cooler periods of the day can also help.
Another way to conserve energy and avoid ozone pollution is to improve energy efficiency at home and in the office. Look for the ENERGY STAR label when purchasing equipment, and consider using gas logs instead of wood. Upgrading air filters to MERV 13 or higher can also help improve indoor air quality. Additionally, using environmentally friendly paints and cleaning products can reduce the release of harmful chemicals that contribute to ozone formation.
Conserving electricity is crucial in reducing ground-level ozone pollution. Setting air conditioners no lower than 78 degrees Fahrenheit can help, as air conditioners contribute to energy consumption and associated emissions. Turning off electrical appliances when not in use and opting for energy-efficient alternatives can also reduce electricity usage and lower ozone levels.
By implementing these measures and conserving energy and electricity, we can collectively work towards reducing ground-level ozone pollution and improving air quality for ourselves and future generations.

Avoid using paints, solvents, and other consumer products that emit VOCs
Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. They are released into the air from some common consumer products like paints, varnishes, wax, and when household chemicals like paint thinners and solvents evaporate. VOCs are also emitted from motor vehicles, chemical plants, refineries, factories, and gas stations.
VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. The risk of health effects from inhaling any chemical depends on how much is in the air, how long and how often a person breathes it in. Breathing in low levels of VOCs for long periods can increase the risk of health problems, especially for those with respiratory problems like asthma, young children, and the elderly.
To reduce exposure to VOCs, it is recommended to minimize the use of VOC-containing products and materials. Opt for low-VOC options where available. For example, water-based paints are the safest option for craft paints. When using products that emit VOCs, increase ventilation by regularly opening windows and using exhaust fans.
Additionally, it is important to store products containing VOCs away from living spaces in well-ventilated areas. Even when not in use, some products still emit VOCs. Before bringing new products that may contain VOCs into your home, such as pressed-wood furniture or new carpets, unwrap them and keep them in a ventilated area outside for 7-10 days to allow many of the VOCs to vaporize before bringing them inside.
