What You'll Learn
Transportation is a major contributor to air pollution
The transport sector is responsible for a large proportion of air pollution, as well as being a leading source of greenhouse gas emissions. In 2010, the transport sector accounted for 14% of global greenhouse gas emissions, and this figure is expected to grow. Transport is a significant and growing contributor to particulate air pollution, with road transport responsible for a substantial share of particulate matter emissions, particularly diesel traffic. Heavy-duty vehicles make up only 10% of all vehicles on the road, yet they generate over 25% of global warming emissions, almost 60% of direct PM2.5 emissions, and a large amount of air pollution.
The impact of these emissions on public health is significant. Pollutants from vehicle exhausts have been linked to adverse impacts on nearly every organ system in the body. Exposure to these pollutants is inequitable, with Latinos, Blacks, and lower-income households disproportionately affected. Higher air pollution concentrations increase the risk of cardiovascular and respiratory diseases, cancer, adverse birth outcomes, and higher death rates. It is estimated that 4.2 million premature deaths are attributed to outdoor air pollution.
However, there are ways to reduce the impact of transportation on air pollution. The EPA has implemented national programs and standards for fuels and vehicles that reduce air pollution, and these have resulted in better air quality and improved health for Americans. The EPA's Clean School Bus Program will replace existing school buses with zero-emission and low-emission models, and the Diesel Emissions Reduction Act provides funding for projects that improve air quality by reducing harmful emissions from diesel engines.
Individuals can also make a difference. People can choose to commute by walking or riding to work instead of driving, and when replacing a car, they can opt for a fuel-efficient vehicle.

The dangers of air pollution to human health
Transport is one of the biggest contributors to air pollution, with motor vehicle emissions remaining the most significant source of common air pollutants. Air pollution is the presence of one or more contaminants in the atmosphere, such as dust, fumes, gas, mist, odours, smoke or vapour, in quantities that can be harmful to human health.
The main pathway of exposure from air pollution is through the respiratory tract. Pollutants such as fine particulate matter, carbon monoxide, ozone, nitrogen dioxide, and sulphur dioxide can penetrate deep into the lungs, enter the bloodstream, and travel to organs, causing systemic damage to tissues and cells. This can lead to inflammation, oxidative stress, immunosuppression, and mutagenicity in cells throughout the body, impacting the lungs, heart, and brain, ultimately leading to disease.
The World Health Organization (WHO) estimates that each year, indoor and outdoor air pollution is responsible for nearly seven million deaths worldwide. The health problems caused by air pollution include lung cancer, ischemic heart disease, chronic obstructive pulmonary disease, pneumonia, and stroke. Maternal exposure to air pollution is also associated with adverse birth outcomes, such as low birth weight, pre-term birth, and small gestational age births.
In addition, air pollution is linked to climate change, with methane, ground-level ozone, and vehicle exhaust contributing to both crises. By trapping the earth's heat in the atmosphere, greenhouse gases lead to rising sea levels, more extreme weather, heat-related deaths, and the increased transmission of infectious diseases.
To reduce the impact of air pollution on human health, individuals can make changes to their commuting habits, such as walking or riding to work instead of driving, and choosing fuel-efficient vehicles.

How to reduce air pollution
Transportation is one of the biggest contributors to air pollution. Motor vehicle emissions are the most significant source of common air pollutants, with more than 55% of all NOx gas emissions originating in the transportation sector. Driving personal vehicles is one of the leading causes of air pollution and greenhouse gas emissions, with personal cars making up more than half of the transportation sector's emissions.
To reduce air pollution during your commute, consider alternatives to driving alone, such as walking, riding a bike, carpooling, vanpooling, or telecommuting. These options can help reduce the number of vehicles on the road and improve air quality. For example, during the COVID-19 pandemic, many pollutants decreased significantly as most people worked from home.
If you must drive, consider choosing a fuel-efficient or electric vehicle. The Green Vehicle Guide provides ratings on the environmental performance of new vehicles sold in Australia. Additionally, maintaining your vehicle properly can help reduce emissions.
Another way to reduce air pollution during your commute is to advocate for better infrastructure for walking, biking, and public transit. Strategic plans like the TCI-P aim to invest in these areas to make eco-friendly commuting options more accessible to communities.
Finally, be mindful of the impact of your daily choices on the environment. Small changes, such as saving energy by turning off appliances and lights when not in use, can collectively make a significant difference in reducing air pollution and creating a cleaner and more sustainable future.
