Smart Swaps To Breathe Cleaner Air

Making small changes in our daily lives can have a significant impact on reducing air pollution. One of the most effective substitutions is choosing to use a bike instead of a car. Bicycles emit fewer polluting particles and harmful gases, such as sulfur dioxide, carbon dioxide, and nitrogen oxide, which contribute to air pollution. In addition to biking, carpooling, using public transportation, walking, and conserving energy are all simple yet powerful ways to improve air quality.

Using a bike instead of a car

Reducing Harmful Emissions

Cars emit a range of harmful pollutants, including carbon dioxide, sulfur dioxide, nitrogen oxide, and particulate matter. By choosing a bike over a car, we can cut down on these emissions and improve air quality. Bicycles are human-powered and do not rely on gasoline, so they don't add pollution to the atmosphere.

Decreasing Fossil Fuel Use

Cars burn fossil fuels, releasing greenhouse gases and contributing to climate change. A typical passenger vehicle emits almost five metric tons of carbon dioxide annually from fuel combustion. Biking reduces fuel consumption and our reliance on fossil fuels, leading to a lower carbon footprint.

Improving Health

Air pollution has detrimental effects on human health, including respiratory issues and heart disease. By reducing air pollution, we can improve the health of individuals and communities. Additionally, biking as a form of active transport has its own health benefits, including a reduced risk of cardiovascular disease and type 2 diabetes.

Reducing Noise Pollution

Cars contribute to noise pollution with their engine noise and traffic congestion. Replacing cars with bikes results in quieter environments, which has a positive impact on ecosystems and human health.

Saving Costs

Apart from the environmental and health benefits, biking is also more affordable than driving. It eliminates fuel costs and can save money on maintenance and parking fees.

Policy Support

Recognizing the benefits of bicycling, organizations like the Intergovernmental Panel on Climate Change have identified it as a solution for a sustainable future. Additionally, the World Health Organization (WHO) has published evidence-based recommendations for policymakers to promote safe cycling and walking, emphasizing their positive impact on health, climate change mitigation, and the environment.

Using dumps instead of landfills

The creation of landfills often involves destroying natural habitats, and the required liners for landfills tend to have leaks, which can result in leachate contaminating nearby water sources and further damaging ecosystems. Additionally, landfills bring hazards such as odour, smoke, noise, bugs, and water supply contamination.

On the other hand, dumps are openings on the ground used for burying trash. They are typically uncontrolled and found in many developing countries. While dumps may not have the same level of environmental controls as landfills, they can still play a role in reducing air pollution by avoiding the use of liners and the creation of leachate.

However, it is important to note that dumps may have their own set of environmental and social challenges. For example, they can still contribute to air pollution through the suspension of particles and odour pollution from deposited waste. Additionally, dumps may not effectively control the spread of diseases, as they are often uncontrolled.

Overall, while using dumps instead of landfills may help reduce some forms of air pollution, it is important to consider the potential trade-offs and challenges associated with dumps. Proper waste management practices, such as recycling, composting, and reducing single-use plastics, can also play a significant role in reducing the negative impacts of both landfills and dumps on the environment and human health.

Using electric vehicles

Electric vehicles (EVs) are a crucial step towards sustainable transportation and can significantly reduce air pollution. They are a cleaner and more cost-effective alternative to traditional internal combustion engine (ICE) vehicles. By eliminating exhaust emissions, EVs help reduce a fleet's greenhouse gas emissions, making them a more environmentally friendly option.

One of the most significant benefits of EVs is their ability to produce zero tailpipe emissions. Unlike traditional engines that combust gasoline or diesel, EVs use rechargeable batteries that are completely emission-free. The most common type, lithium-ion batteries, can be recharged and depleted repeatedly without contributing to air pollution. This makes EVs, especially battery electric vehicles (BEVs), a much cleaner option as they do not have a tailpipe, gasoline engine, fuel tank, or other components that ICE vehicles typically have.

In addition to reducing tailpipe emissions, EVs also lower pollution from brakes. Conventional ICE vehicles primarily use disc brakes, which emit particle pollution. In contrast, EVs utilise regenerative braking, where the electric motor is used for braking, reducing the need for traditional brakes and resulting in less particle emissions. This technology is expected to lead to a substantial reduction in particle pollution as EVs maximise regenerative braking to increase their electric range.

While tyre pollution has been a concern for EVs due to their heavier weight, it is important to note that special tyres designed for EVs aim to minimise wear and tear. Moreover, tyre pollution is not unique to EVs; it is an issue for all road vehicles, including heavy SUVs. Therefore, blaming EVs for tyre pollution is misleading as it ignores the overall air quality benefits they provide.

EVs also offer a reduction in particle pollution. While primary particle mass (PM) emissions from exhaust, tyres, and brakes are often compared between EVs and ICE vehicles, it is important to consider the secondary particle pollution caused by ICE vehicles. These secondary particles, formed from other pollutants such as nitrogen oxides (NOx), hydrocarbons (HC), and ammonia (NH3), contribute to PM2.5 and PM10 pollution, worsening air quality. When all particle sources are considered, studies show that BEV passenger cars and SUVs produce less PM2.5 and PM10 pollution than diesel or petrol cars.

Furthermore, switching to EVs eliminates all toxic tailpipe emissions associated with ICE vehicles, including nitrogen oxides (NOx), carbon monoxide (CO), and hydrocarbons (HC). Nitrogen dioxide (NO2), a harmful pollutant emitted by ICE vehicles, is responsible for tens of thousands of premature deaths in Europe annually. It causes respiratory and cardiovascular issues and can be deadly for asthma sufferers. By transitioning to EVs, we can significantly improve air quality and protect public health.

In summary, electric vehicles offer a range of benefits that contribute to reduced air pollution. From zero tailpipe emissions to lower particle pollution and toxic tailpipe emissions, EVs are a crucial step towards a cleaner and more sustainable future.

Using public transport

Reduced Vehicle Emissions

Public transportation helps to reduce the number of people driving single-occupancy vehicles, which in turn decreases vehicle emissions. This is because public transport moves a greater number of people per vehicle, so there are fewer vehicles on the road. For example, a bus carrying 20 passengers replaces the need for approximately 20 individual cars, significantly reducing the amount of harmful pollutants entering the air.

Fuel Efficiency

Public transport is far more fuel-efficient than single-occupancy vehicles. A full-size diesel-powered bus with just seven passengers offers better fuel economy than the average car. A fully occupied bus has a fuel efficiency six times greater, and a fully occupied train is 15 times more fuel-efficient than the average single-occupancy car. By increasing public transport ridership, fuel consumption is reduced, leading to lower air pollution levels.

Cleaner Fuels

Many cities are now investing in cleaner fuels for their public transportation systems. This means that not only are more people using public transport, but the vehicles themselves are emitting fewer pollutants. This two-pronged approach has a significant positive impact on air quality.

Reduced Traffic Congestion

With more people opting for public transport, there are fewer private vehicles on the roads, reducing traffic congestion. This has a knock-on effect of improving air quality, as vehicles spend less time idling in traffic, emitting pollutants.

Health Benefits

Air pollution has serious health impacts, including respiratory problems, increased cases of pneumonia, premature death, cancer, and other diseases. By reducing air pollution through increased public transport use, these health risks are also reduced. Cleaner air leads to improved respiratory health and a lower risk of developing related diseases.

Economic Benefits

Using hand-powered lawn equipment

Switching to hand-powered lawn equipment is a simple way to reduce this pollution. Many smaller yards can be easily maintained with hand-powered tools like manual mowers, rakes, and shears. These tools are not only better for the environment, but they are also cheaper and easier to maintain than their gas-powered counterparts.

For example, a typical battery-powered lawn mower may be more expensive upfront, but over its lifetime, it will save you money on fuel and maintenance. Plus, you'll be reducing your carbon footprint and helping to improve air quality.

If you're concerned about the time and effort required to use hand-powered tools, consider reducing the grass coverage in your yard. You can replace grass with native plant beds or low-maintenance ground cover, reducing the time and effort needed for lawn care while also supporting the local ecosystem.

So, if you want to do your part in reducing air pollution and improving your carbon footprint, consider making the switch to hand-powered lawn equipment. It's a small change that can have a big impact on the environment.
