Mitigating Air Pollution: Strategies For A Cleaner Tomorrow

Air pollution is a serious global health problem that affects the environment and our health. In 2019, 99% of the world's population lived in places where the air quality did not meet the World Health Organization's (WHO) guidelines. This is due to the harmful particles, chemicals, and gases released into the air, which can cause respiratory and cardiovascular issues, and cancers. While policies to reduce emissions at their sources are important, individual actions can also help reduce exposure and health risks. This includes reducing the use of cars, particularly on days with high air pollution, and opting for more environmentally friendly modes of transportation such as walking, biking, or taking public transportation. Additionally, reducing energy consumption, choosing sustainable products, and limiting the use of products that contain smog-forming chemicals can help improve air quality.

Reduce car usage

Motor vehicles are a significant source of air pollution. In the UK, for example, CO2 emissions from cars make up 13% of the total, and in California, about half of the state's air pollution comes from cars and trucks. Vehicle exhaust is a major source of air pollution, and the increase in road traffic has had a devastating impact on the environment and public health.

To reduce car usage and its impact on air pollution, individuals can make a conscious effort to walk or cycle to their destination, especially for shorter distances and when travelling within their local area. This not only reduces air pollution but also contributes to a healthier and more active lifestyle. For longer distances, consider using public transportation, such as buses or trains, and try to combine trips to reduce the overall number of journeys.

Another way to reduce car usage is to carpool or share rides with colleagues or neighbours travelling in the same direction. This not only reduces the number of vehicles on the road but also fosters a sense of community and can lead to cost savings for all parties involved. Additionally, when purchasing a new vehicle, individuals can opt for fuel-efficient or electric cars. Electric vehicles, hybrid cars, and even compact fuel-efficient gas vehicles produce fewer emissions and are more environmentally friendly alternatives.

Proper maintenance of vehicles is also essential. Keeping your car well-maintained, ensuring proper tyre inflation, and fixing any issues, such as exhaust or oxygen sensor problems, can help reduce emissions. Observing speed limits and driving efficiently by avoiding rapid acceleration and anticipating the road ahead can also contribute to lower emissions.

Switch to electric vehicles

Electric vehicles (EVs) are an essential part of a clean energy future. A recent report by the Electric Power Research Institute (EPRI) and the NRDC confirms that transitioning our transportation sector from its near sole dependence on oil to electricity can lead to big reductions in carbon pollution, along with improvements in air quality.

EVs produce zero direct emissions, while conventional vehicles with internal combustion engines (ICEs) produce direct emissions through the tailpipe, as well as through evaporation from the vehicle's fuel system and during the fueling process. Even PHEVs (plug-in hybrid electric vehicles), which can produce evaporative and tailpipe emissions when using their ICE, generally have lower emissions than comparable conventional vehicles.

According to the EPRI-NRDC study, electrifying all passenger vehicles with renewably generated, zero-carbon electricity by 2050 would address a significant portion of the climate challenge in the transportation sector, which currently accounts for about 60% of carbon pollution. This transition to electric transportation, in combination with a continued clean-up of the electric sector, is crucial for achieving our long-range climate targets and improving air quality.

The benefits of switching to electric vehicles are significant, especially for disadvantaged communities that tend to live in more polluted areas. A 2023 study of air quality levels in the Chicago region found that replacing just 30% of all vehicles with electric versions would save over 1,000 lives and more than $10 billion annually due to reduced pollution-related deaths. Additionally, a recent American Lung Association report estimates that by 2050, a switch to zero-emission vehicles and a decarbonized electric grid could prevent 2.79 million pediatric asthma attacks, 147,000 cases of acute bronchitis in children, and 508 infant deaths.

Therefore, switching to electric vehicles is a crucial step towards reducing air pollution, improving public health, and addressing environmental justice issues.

Improve energy efficiency

Improving energy efficiency is a highly effective way to reduce air pollution. Energy generation is one of the greatest sources of air pollution, releasing pollutants such as particulate matter, nitrogen oxide, sulfur dioxide, volatile organic compounds (VOCs), and carbon monoxide.

One way to improve energy efficiency is to reduce the amount of energy required for certain tasks. This can be achieved by using more efficient appliances, heating systems, buildings, vehicles, and equipment. For example, replacing energy-hungry incandescent light bulbs with compact fluorescent or LED bulbs. "Green" buildings are another way to improve energy efficiency. These are designed, constructed, and operated with energy-efficient principles in mind, such as placing windows where the sun shines on a building in the winter, allowing the building to benefit from natural heat and rely less on heating with fossil fuels.

Another way to improve energy efficiency is to generate more energy per unit of air pollution. Fossil fuel plants, for example, can employ carbon capture and storage technology to reduce carbon emission levels per unit of electricity generated. Smart combustion unit design can also improve efficiency by using the thermal heat gained from one unit to power others, reducing heat loss and, therefore, the need for combustion.

On a larger scale, mandatory energy savings programs for industry, building retrofit and heat-metering reform programs, and the use of standards for personal vehicles have been effective in reducing air pollution. For example, China's improvements in energy intensity between 2000 and 2014 saved 11% of the total primary energy supply and avoided 1.2 gigatonnes of CO2 emissions in 2014. Similarly, the US Clean Air Act from 1970 continues to deliver reductions in air pollution through stringent vehicle emission standards, and it is estimated that for every USD 1 spent on reducing emissions, the return on investment is USD 9 in benefits to public health, environmental improvements, productivity, and consumer savings.

Use eco-friendly products

Using eco-friendly products is a great way to reduce air pollution and its harmful effects on the environment and human health. Eco-friendly products are made from sustainable materials, use renewable energy sources, and reduce waste. They are also free from harsh chemicals and toxins, making them safer for both the environment and personal use.

One of the most significant contributors to air pollution is vehicle emissions. To tackle this, you can switch to electric vehicles or opt for more sustainable transportation methods such as walking, biking, or using public transportation. When flying, choose airlines with strong sustainability initiatives and consider carbon offset programs to mitigate the environmental impact of air travel. Additionally, keeping your car well-maintained and reducing the number of car trips can also help lower emissions and improve air quality.

In your daily life, there are numerous eco-friendly alternatives you can embrace to reduce air pollution. For example, you can switch to biodegradable garbage bags made from natural materials like cornstarch or bioplastic. These bags are environmentally friendly and decompose much faster than traditional plastic bags. Similarly, you can opt for reusable shopping bags made from sustainable materials like cotton, jute, or recycled PET plastic. This simple switch helps reduce the demand for single-use plastic bags and promotes sustainability.

Another area to consider is your cleaning products and personal care items. Traditional cleaning products often contain harsh chemicals that can pollute the air and be unsafe for your health. Eco-friendly cleaning products, on the other hand, are made from natural ingredients such as vinegar, baking soda, lemon juice, or plant-based oils like coconut or olive. These natural alternatives are not only better for the environment but also safer for use around children and pets. Additionally, personal care items like bamboo toothbrushes and biodegradable laundry detergent sheets are excellent choices for reducing plastic waste and conserving natural resources.

Lastly, making small changes in your home can also contribute to reducing air pollution. For example, replacing incandescent light bulbs with compact fluorescent or LED light bulbs reduces electricity consumption and the need for frequent replacements. Using a fan instead of air conditioning, installing low-flow showerheads, and adding insulation to your home are also effective ways to reduce energy consumption and lower your carbon footprint.

Encourage green policies

Encouraging green policies is a crucial step in reducing air pollution and its detrimental effects on the environment and public health. Green policies can be implemented at various levels, from individual choices to industry-wide regulations, to mitigate pollution from significant sources such as vehicles, industries, and power plants.

At the individual level, people can be incentivized to adopt more sustainable practices through policies that promote public transportation, carpooling, biking, and walking. For example, implementing a free public transportation program or offering subsidies for the use of electric vehicles can reduce the number of private cars on the road and, consequently, decrease vehicle exhaust emissions, a major source of air pollution. Policies that encourage the use of energy-efficient appliances, light bulbs, and renewable energy sources like solar or wind power can also help reduce energy consumption and lower air pollution.

Industries and businesses play a significant role in contributing to air pollution, especially in the transportation and energy sectors. Governments can enact and enforce strict emissions standards for vehicles, engines, and power plants, targeting specific pollutants like smog, soot, greenhouse gases, and particulate matter. The Diesel Emissions Reduction Act (DERA) in the United States, for instance, provides funding for owners to replace their diesel equipment with cleaner alternatives, leading to significant reductions in NOx and particulate matter emissions.

Additionally, policies that promote the use of renewable and clean energy sources, such as wind, solar, and hydroelectric power, can reduce the reliance on solid fuels and subsequently decrease air pollution from power plants. International agreements like the Paris Agreement, which focuses on reducing greenhouse gas emissions, have been shown to be effective in controlling air pollution.

By encouraging and implementing these green policies, significant strides can be made in reducing air pollution, protecting public health, and mitigating the environmental impact of human activities. These policies empower individuals, industries, and governments to make sustainable choices that collectively contribute to cleaner air and a healthier planet.
