What You'll Learn
Reduce energy use at home
Energy generation is a major source of air pollution. By reducing energy use at home, you can help improve air quality, curb greenhouse gas emissions, and save money.
Temperature Control
- Ideally, keep your home heated to 68 degrees Fahrenheit during the day and 60 at night. Use extra blankets and sweaters instead of turning up the heat.
- In the summer, dress for the weather and avoid air conditioning if possible. If you need to cool down, try using a ceiling fan first. Fans use significantly less energy than air conditioning.
- If you do use air conditioning, avoid setting the temperature too low.
- Lower your water temperature. Turn your heater down to 120 degrees Fahrenheit. You'll cut your water heating costs by 6-10 percent.
Appliances
- Purchase energy-efficient products and equipment. Look for the Energy Star label to reduce your energy bill by 30 percent and your electric lighting charges by 40 percent while cutting pollution.
- Clean your heating, ventilation, and air conditioning equipment. This will help them last longer, avoid costly downtime, and improve indoor air quality.
Natural Light and Ventilation
- Increase natural light in your home by painting your exterior and interior walls a light color. Paint the edges of windows in white so more light is reflected inside. During the day, open blinds to bring in natural light instead of turning on lights.
- Open windows to create a cross breeze, which can provide significant energy savings.
- Install ceiling fans to increase cooling by moving the air around.
Roofing
Consider a "reflective roof." A roof coated with a white or silvery color reflects solar energy away from the house instead of absorbing it. This reduces the cooling load and saves money on utility bills.
Insulation
Ensure your house is well-insulated. If heated or cooled, never leave windows or doors open. Raise shades on winter days and lower them in the summer.
Transport
Walk, bike, or carpool to reduce vehicle emissions.
Cooking
- Avoid burning firewood or trash.
- Use hand-powered or electric lawn care equipment instead of gasoline-powered.
- Consider solar stoves, microgrids, or home systems using photovoltaic solar or wind energy to power electrical lights or small appliances.
- Install low-emission biomass stoves with features such as secondary combustion, insulated combustion chambers, or fans to improve combustion efficiency and lower emissions.
Remember, small changes can make a big difference in reducing air pollution and creating a healthier environment for yourself and others.

Avoid outdoor activities when air quality is poor
When air quality is poor, it is best to avoid outdoor activities altogether. This is especially important for those who are older or have pre-existing health conditions such as respiratory or cardiovascular disease. Even low-intensity activities like walking can intensify the negative impacts of air pollution for these individuals.
If you are generally healthy, exercising outdoors during moderate air pollution may be safe, according to the EPA's Air Quality Index (AQI). However, it is crucial to monitor how you feel during and after such activities. If you experience any negative symptoms, such as coughing, dryness, or breathlessness, it is best to stop the activity and move indoors.
To make informed decisions about outdoor activities, it is essential to stay updated on the air quality in your area. You can do this by checking the AQI and signing up for alerts about elevated pollution levels. This proactive approach will enable you to plan your activities accordingly and take necessary precautions.
When air quality is poor, consider indoor alternatives for physical activity. Exercising indoors with an air purifier, such as a HEPA filter, can be a healthier option. Additionally, opting for indoor activities at locations with good air filtration systems, such as gyms or indoor sports facilities, can be a safer choice during periods of poor air quality.
It is worth noting that certain outdoor activities can be modified to reduce exposure to air pollution. For example, choosing locations away from traffic or areas with heavy congestion can decrease your exposure to pollutants. Additionally, wearing a tight-fitting mask during outdoor activities can offer some protection, especially when combined with appropriate physical distancing in areas with heavy foot traffic.

Use public transport, walk or cycle
One of the most effective ways to reduce air pollution is to use public transportation, walk, or cycle. By leaving your car at home, you can significantly reduce your carbon footprint and improve air quality.
Public transportation has a proven record of reducing congestion and vehicle emissions. Research shows that public transportation use saves the equivalent of 300,000 fewer automobile fill-ups every day in the United States alone. Additionally, public transportation systems are increasingly adopting more sustainable practices, such as expanding their metro networks and transitioning to electric buses and trains. These efforts contribute to further reductions in air pollution.
Walking and cycling are excellent alternatives to driving, especially for shorter trips. They not only improve your health and reduce physical inactivity but also play a crucial role in mitigating climate change and improving the environment. Evidence suggests that significant shifts toward walking and cycling can address issues related to emissions of air pollutants, greenhouse gases, and noise.
To promote active mobility, it is essential to create infrastructure that supports safe walking and cycling. This includes redesigning urban spaces to ensure daily needs can be met within accessible distances. Measures such as implementing dedicated cycle lanes, providing secure bike parking, and creating green spaces and trails can encourage more people to choose walking and cycling as their preferred mode of transportation.
By choosing to use public transportation, walk, or cycle, you can directly contribute to reducing air pollution and making a positive impact on the environment and your well-being.

Support local anti-pollution initiatives
Supporting local anti-pollution initiatives is a great way to get involved in tackling air pollution. Here are some ways to do this:
Get Informed and Stay Involved
Keep an eye on local developments and policy changes that focus on air pollution. For example, some areas in the UK are developing Clean Air Zones, also known as Low Emission Zones in London and Scotland, which aim to reduce motorised transport. Being aware of such initiatives can help you adapt your behaviour and support these changes.
Support Local Organisations
Get involved with local organisations that are working to improve air quality. For example, Sustrans is a UK-based organisation that encourages walking and cycling to reduce congestion and air pollution. They provide resources and tips to help people make the switch to more sustainable travel options.
Advocate for Change
Direct local businesses, city offices, and school districts toward programs that can help them reduce air pollution. For instance, the GreenStep Cities initiative in the US sees city and county officials passing local ordinances, creating incentives, and educating residents on best practices for sustainability.
Improve Local Air Quality
Support local garden initiatives or start your own to improve air quality in your neighbourhood. Plants help clean the air by consuming CO2. The Tree Council can provide advice on which trees are best suited for your neighbourhood.
Reduce Personal Emissions
On an individual level, you can reduce your carbon footprint by walking, cycling, or using public transport instead of driving. Combine your trips and buy in bulk to reduce the number of car journeys. Making these changes can have a significant impact when done collectively.

Avoid backyard fires
Backyard fires are a significant contributor to air pollution, especially in cities. Smoke from burning wood contains gases and fine particles, also known as particle pollution or particulate matter, which can cause unhealthy conditions for hundreds of people, particularly those with asthma and other respiratory conditions.
To reduce the impact of backyard fires on air quality, it is essential to follow these guidelines:
- Limit backyard fires, especially in urban areas. The smoke from these fires can have detrimental effects on people with asthma or other lung conditions, as cities already have higher pollution levels than rural areas.
- Keep fires small and brief, ideally three feet across or less, and avoid burning during air quality alerts or stagnant weather conditions.
- Only burn dry, seasoned firewood. Green wood, construction waste, plastic, garbage, and yard waste produce more smoke and can release toxic fumes.
- Consider switching to natural gas or propane burners, which are cleaner and easier alternatives to wood-burning.
- Be considerate of your neighbours' health and comfort. Even if they do not have respiratory issues, inform them beforehand so they can close their windows.
- Sign up for alerts or check daily updates to stay informed about elevated air pollution levels in your area.
By following these guidelines, you can help minimise the impact of backyard fires on air quality and create a healthier environment for yourself, your neighbours, and your community.
