There are many ways to reduce pollutants, especially when it comes to air pollution. Air pollution can be caused by nitrogen dioxide, particulate matter, and carbon dioxide emissions, which are often produced by cars and road transport. To reduce this, people can make changes to their travel behaviour by walking, cycling, or taking public transportation. In addition, people can service their cars regularly, switch to cleaner cars, and avoid refuelling during the hottest hours of the day. Aside from reducing air pollution, people can also lower their household pollution footprint by using natural, non-synthetic fertilizers, building healthy soil, and reducing the use of pesticides.

Reduce vehicle emissions by walking, cycling or taking public transport
Walking, cycling, and taking public transportation are all effective ways to reduce vehicle emissions and, thus, pollutants.
Walking and Cycling
Walking and cycling can significantly reduce vehicle emissions by substituting short car trips. A study found that half of all car trips are less than 3 miles long, and walking or cycling could realistically replace 41% of these short trips. This change could save nearly 5% of CO2e emissions from car travel, in addition to the emissions already avoided due to existing walking and cycling habits. While the impact of improved walking and cycling infrastructure on carbon emissions reduction is debated, the combination of methods for data collection in this study contributes to future research on the wider environmental impacts of active travel, including improved air quality, reduced noise, and reduced fossil fuel use.
Cycling is one of the greenest ways to travel, offering a lower carbon footprint per kilometre travelled than even electric cars. Replacing car journeys with cycling can be done immediately, whereas transitioning to electric vehicles will take decades. Cycling also addresses health problems associated with sedentary lifestyles, increases life expectancy, and reduces particulate air pollution, which has been linked to an increased COVID-19 death rate.
Public Transportation
Public transportation offers significant environmental benefits by reducing greenhouse gas emissions and conserving energy. In the United States, public transportation saves 37 million metric tons of carbon dioxide annually, equivalent to the emissions from generating electricity for 4.9 million households. Additionally, public transportation use saves the U.S. 4.2 billion gallons of gasoline annually. The move from diesel to compressed natural gas (CNG) fuel in public transportation systems also contributes to cost savings and environmental benefits, reducing greenhouse gas emissions and taking passenger cars off the road.

Use natural, non-synthetic fertilisers to prevent polluted runoff
Fertilisers are essential for agriculture and farming, which are necessary for human survival. For thousands of years, farmers relied on natural fertilisers like fish, manure, or ground bones. This natural agricultural process didn't harm the land. However, modern agricultural practices have introduced pollution processes, sometimes causing land, ecosystem, and environmental degradation, as well as agricultural runoff in drinking water.
One of the primary effects of fertiliser runoff is eutrophication, which occurs when a body of water becomes overly enriched with nutrients, leading to excessive plant growth and, eventually, oxygen depletion. This upsets the delicate balance of aquatic ecosystems, causing some species to dominate while others suffer. Eutrophication can lead to hypoxia, or "dead zones," resulting in fish kills and a decrease in aquatic life.
To prevent fertiliser runoff and its adverse effects, it is essential to use natural, non-synthetic fertilisers. Natural fertilisers tend to be slower-acting and release nutrients gradually, reducing the risk of excess nutrients washing away into nearby water bodies. Additionally, natural fertilisers often improve soil health, reduce erosion, and decrease the likelihood of runoff.
By contrast, synthetic fertilisers can quickly release high concentrations of nutrients, which can be easily washed away by rainfall or snowmelt, ultimately ending up in rivers, lakes, or groundwater. This process leads to nutrient pollution, adversely affecting water quality and aquatic ecosystems.
Farmers can adopt several strategies to manage fertiliser use and prevent runoff. These include installing fences along water bodies to restrict livestock access, implementing watershed management practices, and engaging with various stakeholders to reduce nutrient pollution. By combining natural fertilisers with proper management practices, farmers can minimise fertiliser runoff and its negative consequences on the environment and human health.

Avoid open burning of waste, especially trade waste and tyres
Open waste burning is a significant source of dangerous pollutants and a major health and environmental concern. It releases toxic chemicals and particulate matter, which can have severe health impacts, including respiratory and cardiovascular problems, and cognitive impairment. Vulnerable groups, such as children and the elderly, are particularly at risk. Therefore, it is crucial to avoid the open burning of waste, especially trade waste and tyres.
Trade waste and tyres, when burned, produce toxic emissions that are harmful to human health. The open burning of these materials is prohibited in many places due to the serious health and environmental risks they pose. For example, in the state of Illinois, the open burning of commercial/trade waste and specific types of waste, such as food, food scraps, and food packaging, is illegal.
To avoid open burning, it is essential to promote decentralized waste management systems at the community level. This reduces the likelihood of dumping and burning waste. Implementing measures such as waste segregation at the source, improving waste collection systems, and addressing behavioural issues through education and awareness are crucial steps.
Additionally, supporting the creation of integrated solid waste management systems and improving landfill management can help reduce the occurrence of open burning. This includes waste separation and the inclusion of informal waste pickers in the formal sector. Furthermore, preventing fires at dumpsites through the reduction of unsegregated organic waste and the promotion of biomining of legacy waste is essential.
By taking these proactive measures and working collaboratively between different departments and agencies, we can effectively address the issue of open burning, especially the burning of trade waste and tyres, and mitigate the associated health and environmental risks.

Fuel vehicles in the early morning or late at night during the summer
It is recommended that you fuel your vehicle in the early morning or late at night during the summer. This is because the emissions from the millions of vehicles on the road each day contribute significantly to air pollution. The power to move a car comes from burning fuel in an engine, and the combustion process produces exhaust and evaporates the fuel, both of which pollute the air.
Ozone, a secondary pollutant, is formed when hydrocarbons react with oxides of nitrogen in the presence of sunlight. This process is temperature-dependent, and higher temperatures increase the rate of reaction, leading to increased ozone levels. Therefore, it is advisable to refuel vehicles during the cooler parts of the day in the summer to mitigate the formation of ozone.
Additionally, gasoline vapors can escape into the atmosphere during refueling, especially in hot weather. Refueling during the early morning or late at night can reduce the amount of gasoline vapor released into the atmosphere, as lower temperatures can help contain the vapors.
To further reduce vehicle emissions and pollution, it is essential to maintain your vehicle and keep it in good repair. Regular oil changes, tire inflation checks, and addressing any “check engine” lights are crucial steps in ensuring your vehicle operates efficiently and cleanly. Newer vehicles tend to emit less pollution due to stricter emission standards and more advanced emission control technologies. When purchasing a new vehicle, consider choosing a fuel-efficient model with low greenhouse gas emissions, as these vehicles can help the environment and save you money on fuel costs.
Lastly, driving habits can also impact pollution levels. Reducing your driving speed, accelerating gradually, and avoiding rapid stops and starts can help decrease fuel consumption and lower emissions. Carpooling, using public transportation, or opting for walking or biking are also effective ways to reduce pollution and your carbon footprint.

Choose energy-efficient appliances and heating systems
Energy efficiency is one of the most cost-effective ways to reduce air pollution. By using energy-efficient appliances and heating systems, you can significantly lower your energy costs and reduce pollution.
Energy-efficient appliances are designed to use less energy to function optimally, which in turn releases fewer pollutants into the air and reduces your carbon footprint. For example, an energy-efficient washing machine can use 25% less energy and 33% less water than a traditional washer. Similarly, an energy-efficient dishwasher saves an average of over 3,800 gallons of water in its lifetime.
When it comes to heating, heat pumps are an efficient way to regulate the temperature in your home. Unlike traditional heating systems that create heat, heat pumps move heat from the surrounding air, making them more energy-efficient. Heat pump water heaters, in particular, can help a family save a significant amount of energy and money. On average, an ENERGY STAR-certified heat pump water heater uses 70% less energy and can help a family of four save over $550 a year compared to a standard electric water heater.
In addition to heat pumps, there are other ways to improve the energy efficiency of your heating system. For example, adding more insulation to your attic helps keep warm air inside during winter and prevents hot air from entering during summer, reducing the need for heating or cooling. Energy-efficient windows are also effective, as they are designed to reduce heat exchange and air leaks, making it easier to maintain a comfortable temperature indoors without using as much energy.
By choosing energy-efficient appliances and heating systems, you can play a crucial role in reducing air pollution while also enjoying the benefits of lower energy costs and a reduced carbon footprint.
