Air Pollution: Strategies For A Cleaner Tomorrow

Air pollution is a serious problem, but it is not an unsolvable one. In 2019, 99% of the world's population lived in areas where air quality did not meet the World Health Organization's guidelines, leading to 4.2 million premature deaths worldwide. While the problem is severe, there are many ways to reduce air pollution and improve air quality. At the individual level, people can reduce their energy consumption, use less gasoline, and opt for public transportation, biking, or walking. At the community level, local businesses, city offices, and school districts can be directed toward programs that help them reduce air pollution and become more sustainable. At the national level, governments can pass laws and regulations to restrict air pollution and improve air quality.

Reduce vehicle emissions

Motor vehicles are a significant source of air pollution. Cars, trucks, buses, off-road vehicles, and planes all contribute to the problem. Burning gasoline and diesel fuel creates harmful byproducts like nitrogen dioxide, carbon monoxide, hydrocarbons, benzene, and formaldehyde. Additionally, vehicles emit carbon dioxide, a common greenhouse gas.

• Reduce idle time: Idling vehicles pollute the air and waste fuel. Modern vehicles do not need to be "warmed up" in the winter, so there is no need to turn on the engine until you are ready to drive. If you anticipate being stopped for more than 10 seconds, turn off your engine, as this will use less fuel than restarting the engine. Many hybrid and electric vehicles now have an automatic start and stop system that turns off the engine when the speed is zero.
• Drive efficiently: Observing speed limits and accelerating gradually can help to reduce fuel consumption and emissions. Getting a vehicle moving from a complete stop uses the most energy, so go easy on the accelerator and try to anticipate the road ahead.
• Choose a fuel-efficient vehicle: Electric, hybrid, and compact fuel-efficient gas vehicles emit fewer pollutants than traditional gasoline engines. While the initial cost of these vehicles can be high, prices are becoming more affordable as they become more common. If a larger vehicle is required, compare the fuel economy of available options.
• Reduce the amount you drive: Opt to walk or bike to your destination if possible. Using public transportation or participating in car cooperatives can also help to reduce vehicle emissions.
• Maintain your vehicle: Regularly changing your engine oil and using the correct grade of oil is vital for maintaining efficiency. Using premium fuel that contains additives can also improve fuel efficiency and reduce emissions. Additionally, ensure you regularly check your tire pressure, as underinflated tires can reduce fuel economy.
• Use alternative equipment: Gas-powered lawn and garden equipment emit significant amounts of pollutants. Opt for hand-powered or electric alternatives instead.

Limit backyard fires

Backyard fires are a significant contributor to air pollution, especially in cities where pollution levels are already high. Smoke from burning wood contains gases and fine particles, which can cause eye and lung irritation, headaches, dizziness, coughing, wheezing, and asthma. It can even be deadly, especially for children, older people, and those with heart or lung conditions.

To limit the negative impact of backyard fires, it is important to follow certain guidelines. Firstly, keep fires small and brief, ideally 3 feet across or less. Only burn clean, dry, seasoned firewood, as green wood creates more smoke and toxic air pollutants. Avoid burning waste, such as construction materials, plastic, garbage, or yard waste, as these can release dangerous toxins. Check local regulations and avoid burning wood during air quality alerts or Spare the Air Alert days, when air pollution is already high.

Additionally, consider switching to natural gas or propane burners, which produce fewer harmful air pollutants. If you use a wood-burning device, ensure it is EPA-certified. Be mindful of your neighbours and wind direction when lighting a fire, as smoke can impact the health of those nearby.

Finally, consider alternatives to burning wood altogether. Electric or hand-powered lawn equipment, for example, can reduce pollution compared to gas-powered engines.

Use energy-efficient appliances

Energy efficiency is one of the easiest and most cost-effective ways to reduce air pollution. It involves using less energy to complete the same tasks, cutting energy bills and reducing pollution in the process. Energy efficiency can be achieved by using energy-efficient appliances, such as those with the Energy Star label from the US Environmental Protection Agency (EPA). These products are certified to deliver efficiency performance and savings, helping to protect your health, the environment, and your wallet.

Energy-efficient appliances can be more expensive upfront, but they typically save you money in the long term by reducing energy costs. For example, an energy-efficient electric heat pump water heater could cost $700 more than a standard electric water heater, but it is estimated that the energy savings would add up to $3,500 over the lifetime of the equipment. Many utilities offer rebates and discounts to help offset the initial cost.

The EPA estimates that the Energy Star program has reduced carbon pollution by 4 billion metric tons while saving $500 billion on household energy bills. Energy-efficient appliances can include heat pump water heaters, which use 70% less energy, as well as windows made with materials that reduce heat exchange and air leaks, and insulation to keep warm air inside during winter and out during summer.

By reducing the amount of energy required for certain tasks, energy efficiency can help reduce air pollution from coal- and gas-fired power plants and improve air quality, leading to a healthier and happier world.

Plant and care for trees

Trees are an excellent way to combat air pollution. They act as the “lungs” of an ecosystem, absorbing carbon dioxide and releasing oxygen into the atmosphere. They also act as the "liver" of an ecosystem, filtering atmospheric pollutants like sulphur dioxide and nitrogen dioxide through their leaves.

When planting trees to combat air pollution, it is important to choose the right species. The US Forest Service provides free software called iTree Species, which ranks species based on variables including air-pollution removal abilities, carbon storage, and VOC emissions. For example, the municipality of Oakville in Ontario, Canada, found that the Norway maple provided more benefits to air quality than any other tree. However, because Norway maples already accounted for more than 10% of their urban canopy, they chose not to plant more to preserve biodiversity.

It is also important to consider the location of the trees. Trees and other vegetation planted in the right places can form a barrier between people and pollutants, providing cleaner, healthier air. For example, trees can be planted to create green spaces in cities, allowing people to walk or cycle through parks instead of alongside busy roads, inhaling the fumes and detritus of urban traffic.

Once the right species and location have been chosen, it is important to care for the trees properly. This includes regular maintenance, such as pruning and watering, to ensure the trees remain healthy and effective at reducing air pollution.

In addition to planting and caring for trees, there are other ways to reduce air pollution. For example, reducing emissions from vehicles, power plants, and industrial facilities can help improve air quality. This can be done by driving less, using public transportation, or switching to electric vehicles. Improving energy efficiency and reducing the use of fossil fuels can also help reduce air pollution.

Support government initiatives

Individuals can support government initiatives to reduce air pollution in several ways. Firstly, staying informed about local and national air quality standards and regulations is essential. Understand the specific air pollution challenges facing your community and the measures that local, state, and federal governments are implementing to address them. This knowledge will enable you to make informed decisions and actively participate in improving air quality.

Another way to support government initiatives is to advocate for stronger policies and ensure their effective implementation. Contact your local representatives and express your support for policies that address air pollution. Encourage them to prioritize clean air initiatives and provide the necessary resources for enforcement. By holding our leaders accountable, we can ensure that air pollution remains a political priority and that regulations are translated into tangible actions.

In addition, individuals can actively participate in government-led programs and campaigns aimed at reducing air pollution. For example, the US Environmental Protection Agency (EPA) offers various programs, such as the SmartWay program, which helps companies move goods more sustainably and efficiently, reducing emissions and improving air quality. The EPA also provides guidance and incentives for businesses, cities, and communities to reduce their environmental impact and air pollution levels. By enrolling in or promoting these programs, individuals can contribute to larger-scale efforts to tackle air pollution.

Furthermore, supporting government initiatives can involve engaging with local communities and grassroots organizations working towards cleaner air. These groups often have a deep understanding of the unique air pollution challenges faced by specific regions and collaborate with local governments to implement effective solutions. Individuals can join or volunteer with these organizations, helping to spread awareness, educate community members, and advocate for change at the local level. This bottom-up approach ensures that diverse community needs are represented and addressed in air pollution reduction efforts.

Lastly, individuals can amplify the impact of government initiatives by adopting sustainable practices in their daily lives. This includes reducing vehicle emissions by carpooling, using public transportation, or switching to electric vehicles; conserving energy at home; and properly managing waste to prevent the release of harmful substances into the atmosphere. By combining individual actions with support for government initiatives, we can collectively make a significant difference in improving air quality and protecting public health.
