What You'll Learn
Choose fuel-efficient vehicles with low emissions
When shopping for a car, it is important to look for fuel-efficient vehicles with low emissions to help the environment and save money on fuel costs.
Firstly, it is important to understand the different types of engines and their effects on the environment. Petrol and diesel engines have different impacts. Diesel engines generally produce less CO2 but emit more air pollutants than petrol engines. As a rule of thumb, if you intend to use the vehicle for long-distance or motorway driving, a diesel engine is more fuel-efficient and has lower CO2 emissions. If the vehicle will be used in urban areas, where air quality is a greater consideration, a fuel-efficient petrol engine is a better option.
Secondly, it is good to be aware of the various vehicle options available. There are now many hybrid models and even all-electric vehicles on the market. Electric, hybrid, and even compact fuel-efficient gas vehicles may not meet all drivers' needs, but they are becoming more common and affordable. Organisations like the Vehicle Certification Agency (VCA) can help you identify the most efficient vehicle in each class, reducing your CO2 emissions and cutting fuel bills. For those in the European Union, it is recommended to opt for the most recent EURO (European Emissions Standards) classification. Electric vehicles are particularly recommended in countries with a low-carbon energy mix.
Thirdly, it is worth considering buying second-hand. This can help reduce emissions from the production phase. When buying second-hand, it is important to assess the safety, financial, and technical implications, as well as the availability of parts and maintenance services.
Finally, it is beneficial to utilise resources and tools that can help you make an informed decision. The US EPA's Green Vehicle Guide and Fuel Economy and Environment Label can help you learn about and compare different vehicle models to find the most fuel-efficient and environmentally friendly option for your needs. Similarly, the Energy Saving Trust can help you improve your carbon footprint and reduce costs.

Drive less, walk or bike more
Driving less and walking or biking more is one of the most effective ways to reduce car pollution. Motor vehicles are the largest source of air pollution in many places, such as Washington State. By driving less, you can significantly reduce your carbon footprint and improve air quality.
Walking or biking instead of driving is a form of active mobility, which has been shown to have numerous benefits. Active mobility can help reduce physical inactivity, which causes approximately one million deaths per year in the European Region, according to the World Health Organization (WHO). It is also associated with a lower risk of cardiovascular disease, type 2 diabetes, and cancer-related mortality.
In addition to the health benefits, active mobility can help reduce air pollution. Vehicles emit harmful pollutants such as nitrogen dioxide, carbon monoxide, hydrocarbons, benzene, formaldehyde, and carbon dioxide, a significant contributor to climate change. By choosing to walk or bike instead of drive, you can help curb these emissions and improve the environment.
To implement this solution, individuals can make a conscious effort to choose walking or biking for shorter distances instead of driving. This can be supported by infrastructure improvements, such as safe walking and biking trails, secure bike parking, and access to public transportation for longer distances. Additionally, maintaining your vehicle and choosing a fuel-efficient car when necessary can further reduce pollution.
By driving less and choosing active mobility options, individuals can play a crucial role in reducing car pollution, improving their health, and contributing to the mitigation of climate change. It is a simple yet impactful step towards a more sustainable future.

Maintain your vehicle and keep it in good repair
Maintaining your vehicle and keeping it in good repair is essential to reducing car pollution. Here are some ways to do this:
Firstly, keep your vehicle well-maintained by following the manufacturer's maintenance schedule and guidelines. This includes getting regular tune-ups and using the recommended motor oil. Regular oil changes are crucial, as well as ensuring your car is in alignment. Properly inflating your tires can make your vehicle more fuel-efficient, and you can find the correct tire pressure in your owner's manual.
Additionally, tighten the gas cap after every fill-up until you hear it click. A loose, cracked, or missing gas cap leads to lower gas mileage and increased harmful emissions. It is also important to note that modern vehicles do not require "warming up" in the winter, so there is no need to turn on the engine until you are ready to drive. Idling for more than 10 seconds uses more fuel and causes more pollution than restarting your engine.
Another way to maintain your vehicle is to opt for a commercial car wash when cleaning it. This can significantly reduce water consumption and prevent oil and gasoline from entering storm drains.
Finally, be mindful of choosing a trustworthy mechanic and auto shop. Some shops may push expensive specialty products and services that do not deliver on their promises and could even damage your car.

Avoid idling and accelerating rapidly
The way you drive can significantly impact your vehicle's emissions. Observing posted speed limits and avoiding rapid acceleration are essential steps in reducing pollution. When you drive faster, your vehicle burns more fuel and emits more pollutants. Instead, accelerating gradually and gently helps to reduce fuel consumption. Getting a vehicle moving from a complete stop requires the most energy, so it is best to be gentle on the accelerator. Anticipating the road ahead and avoiding unnecessary acceleration can also help.
Idling your vehicle, whether a car, truck, or bus, contributes to air pollution, fuel wastage, and excess engine wear. Modern vehicles do not require "warming up" in cold weather, so it is best to avoid idling and only turn on the engine when you are ready to drive. Restarting your vehicle does not use more fuel than letting it run and will not cause excessive wear on the starter or other parts.
Reducing idling is especially important for diesel vehicles, as idling diesel engines emit diesel exhaust, a harmful greenhouse gas. By reducing idling, you can decrease your vehicle's emissions and improve fuel efficiency. This is particularly relevant for school buses, as idling buses expose children to diesel exhaust and increase pollution.
To reduce idling, you can implement strategies such as planning your route to minimise stops, turning off your engine when parked, and using vehicle accessories that reduce idling, such as start-stop systems or idle-reduction technologies. Additionally, when shopping for a new vehicle, consider fuel efficiency and choose vehicles with lower greenhouse gas emissions.
By following these driving tips and reducing idling, you can significantly contribute to reducing car pollution and improving air quality. Remember, small changes in your driving habits can make a big difference in reducing vehicle emissions and mitigating climate change.

Support public transport and carpooling
Supporting and encouraging the use of public transportation and carpooling can be a highly effective strategy to reduce car pollution. Firstly, it is important to acknowledge that vehicles are a significant contributor to air pollution, with a typical passenger car emitting approximately 4.6 metric tons of carbon dioxide annually. This issue is particularly prominent in urban areas, where the concentration of cars leads to increased congestion and higher levels of pollution.
Public transportation offers a solution by removing vehicles from the road. A bus or train can transport a significant number of people, reducing the need for multiple cars, which would otherwise emit pollutants individually. This shift can lead to a substantial decrease in congestion, improving traffic flow and resulting in shorter journey times. Additionally, public transportation systems often utilize more energy-efficient vehicles and optimize routes to minimize fuel consumption, further reducing pollution.
Carpooling is another effective strategy to reduce car pollution. By having multiple passengers in a single vehicle, carpooling decreases the number of cars on the road. This approach can significantly reduce infrastructure requirements, pollution levels, costs, and congestion. For example, by filling all five seats in a car, we can transport people with only 20% of the infrastructure and pollution of single-occupancy vehicles.
To encourage the use of public transportation and carpooling, several measures can be implemented. Firstly, investing in infrastructure improvements, such as Transit Signal Priority (TSP), can help reduce idling and keep public transportation routes on schedule, making it a more attractive option for commuters. Implementing low-emission or zero-emission zones in cities can also incentivize the use of public transportation and carpooling by discouraging the use of highly polluting private vehicles. Additionally, providing dedicated lanes for high-occupancy vehicles and increasing congestion pricing can make carpooling a more appealing choice.
In conclusion, supporting public transportation and carpooling offers a significant opportunity to reduce car pollution. By removing vehicles from the road, optimizing fuel efficiency, and reducing congestion, we can create a healthier and more sustainable environment for our communities. Implementing the right measures and incentives can encourage the adoption of these practices, leading to tangible benefits in addressing car pollution and its impact on climate change.
