Drive less, walk or cycle
Driving less and opting to walk or cycle instead is a simple yet effective way to reduce air pollution. Transportation is the largest source of carbon emissions, with vehicle exhaust being a major contributor to air pollution. By choosing to walk or cycle for shorter distances instead of driving, you can significantly reduce your carbon footprint and improve air quality.
Walking and cycling not only reduce greenhouse gas emissions but also offer numerous health benefits. According to the World Health Organization (WHO), active commuting is associated with a 10% decrease in the risk of cardiovascular disease and a 30% decrease in type 2 diabetes risk. Additionally, cancer-related mortality is 30% lower among those who commute by bicycle. Walking for 30 minutes or cycling for 20 minutes on most days can reduce mortality risk by at least 10%.
While active travel has its advantages, it is important to consider air pollution exposure, especially in areas with high levels of air pollutants. In such cases, the benefits of physical activity may be outweighed by the negative impact of air pollution. However, in most urban environments, the benefits of physical activity outweigh the risks associated with air pollution. To maximize the benefits of active travel, individuals can opt for routes with lower air pollution levels or utilize resources like the WHO Ambient Air Pollution Database to make informed decisions.
To promote walking and cycling as viable alternatives to driving, it is essential to address safety concerns. This includes implementing infrastructure improvements, such as dedicated bike lanes and pedestrian-friendly designs, to ensure the well-being of cyclists and pedestrians. Additionally, initiatives like the Clean Air Council's Vision Zero aim to reduce traffic fatalities to zero by advocating for better road design and data-driven approaches to road safety.
By driving less and embracing walking or cycling, individuals can play a crucial role in reducing air pollution, improving their health, and contributing to a more sustainable future. This shift towards active transport can also lead to a reduction in traffic congestion and a more enjoyable commuting experience for everyone.

Choose efficient appliances
Energy efficiency is one of the best ways to reduce air pollution. The energy system contributes significantly to economic and social progress, but it also has negative side effects. Scaling up the use of energy-efficient appliances and lighting reduces the demand for electricity generation and, therefore, reduces air pollution.
The average household has a larger carbon footprint than the average car. The energy used in our homes comes from power plants that burn fossil fuels, causing air pollution. By using energy-efficient appliances, we can significantly reduce air pollution.
When it comes to choosing efficient appliances, there are a few things to keep in mind. Firstly, consider the size of the appliance and how it fits your usage needs. For example, an inflatable hot tub uses less energy than a fitted one because it is only connected to power when in use. Secondly, look for appliances with energy-saving settings. An 'eco' setting lets you save energy and water without compromising performance. Thirdly, don't just consider the upfront cost of a new appliance; think about the cost of operating it as well.
In addition to choosing efficient appliances, there are other simple steps you can take to reduce air pollution in your daily life. For example, you can walk, bike, carpool, or take public transportation instead of driving alone. You can also reduce your use of fuel-burning appliances, such as gas stoves, and opt for more energy-efficient alternatives.

Use public transport
Using public transport is a great way to reduce air pollution. Firstly, it reduces the number of people driving single-occupancy vehicles, which have a very low fuel efficiency per rider. In fact, public transport produces 95% less carbon dioxide, 92% fewer volatile organic compounds, 45% less carbon monoxide, and 48% less nitrogen oxide per passenger mile than single-occupancy vehicles. This means that for every person who takes public transport instead of driving, the amount of harmful pollutants entering the atmosphere is significantly decreased.
Public transport also helps to reduce air pollution by reducing vehicle emissions. Most public transport does not offer door-to-door service, so riders usually have to walk a few blocks to get to and from their stop. This reduces the number of vehicles on the road and therefore the amount of pollution in the air. A study conducted following the 1996 Atlanta Olympic Games found that expanded public transportation services reduced peak auto use by 22.5% and led to decreased amounts of mobile source emissions from single-occupancy vehicles. During the Games, emergency rooms and hospitals saw a 42% decrease in the amount of asthma-related admissions due to lower levels of air pollution.
Another benefit of using public transport is the potential for increased social inclusion and mobility for lower-income citizens. This has been demonstrated in the Estonian capital, Tallinn, where public transport has been free for residents since 2013. This initiative increased public transport usage by 14% in the first year and greatly benefited lower-income households. However, some critics argue that free public transport does not necessarily reduce car use and that investing in improved services and penalizing car use may be more effective in reducing air pollution.
Overall, using public transport is a great way to reduce air pollution, and it also offers social and economic benefits. By choosing public transport over driving, individuals can help to improve air quality and reduce the region's carbon footprint, leading to a healthier environment for everyone.
