What You'll Learn
Choose fuel-efficient vehicles with low emissions
When shopping for a new car, it is important to consider fuel efficiency and emissions. Burning gasoline and diesel fuel creates harmful byproducts like nitrogen dioxide, carbon monoxide, hydrocarbons, benzene, formaldehyde, and carbon dioxide, which is the most common human-caused greenhouse gas. By choosing a fuel-efficient vehicle with low emissions, you can help reduce air pollution and combat climate change.
There are several options available when it comes to fuel-efficient vehicles with low emissions. Electric vehicles, for example, are a great choice, especially in countries with a low-carbon energy mix. Hybrid vehicles, such as the Chevrolet Tahoe, Ford Escape, and Toyota Prius, offer the benefits of both electric and gasoline engines, resulting in lower emissions. Some vehicles, like the Honda Civic and Toyota Camry, also have hybrid versions. If you require a larger vehicle, consider the latest hybrid SUVs, which produce lower emissions without compromising on power.
When evaluating fuel-efficient vehicles, it is essential to consider safety, financial implications, and technical aspects. Opting for a second-hand car can be a cost-effective option while also reducing emissions from the production phase. Ensure that you assess the availability of parts and maintenance services to keep your vehicle in good condition. Additionally, consider the context of your usage, as fuel type selection depends on specific factors such as safety and financial constraints.
To make informed choices, utilise available resources such as the EPA's Green Vehicle Guide and Fuel Economy and Environment Label in the United States. These tools allow you to compare vehicle models and identify the most fuel-efficient and environmentally friendly options that meet your needs. Similar resources are available for vehicles purchased in the European Union, where you can refer to the EURO (European Emissions Standards) classification. By choosing fuel-efficient vehicles with low emissions, you can play a part in reducing greenhouse gas emissions and creating a cleaner environment.

Maintain your car and keep it in good repair
Maintaining your car and keeping it in good repair is essential to reducing its environmental impact. Firstly, it is important to regularly change your car's engine oil to maintain optimal efficiency. Check your vehicle's handbook for the recommended service intervals and oil level, and be sure to use the correct grade of oil.
Another key area to focus on is the air filter. A clogged air filter restricts airflow to the engine, causing issues and premature wear and tear. Check the recommended service intervals for air filter replacement, and consider replacing it more frequently if you live in a dusty area.
Additionally, it is important to regularly check your tyre pressure. Underinflated tires can reduce fuel economy and increase fuel consumption and CO2 emissions. Follow the manufacturer's recommendations for tyre pressures, and consider choosing tires with low rolling resistance to further reduce fuel consumption.
It is also beneficial to use a cleaning agent in your fuel system to remove harmful deposits and lower emissions. Premium fuels often contain active cleaning agents that remove dirt from the engine, improving fuel efficiency and reducing emissions.
Finally, modern vehicles have complex emission controls to ensure they run as cleanly as possible. Ensure these controls are functioning as designed, as a malfunctioning system will cause the vehicle to pollute more than it should.

Drive less, walk or bike more
Driving less and walking or biking more is a highly effective way to reduce air pollution from motor vehicles. Motor vehicles are the largest source of air pollution in Washington State, and vehicles produce one-third of all US air pollution. By choosing to walk or bike, you can significantly lower your carbon footprint and decrease your risk of cardiovascular disease and type 2 diabetes.
Walking and biking offer numerous benefits beyond reducing pollution. They can help tackle physical inactivity, which causes one million deaths per year in the European Region, and obesity, which is a significant issue in the same region, with two-thirds of adults and one in three children being overweight or obese. Active commuting, such as walking or biking, can reduce the risk of cardiovascular disease by about 10% and lower the risk of type 2 diabetes by 30%. Additionally, cancer-related mortality is 30% lower among those who commute by bike.
To encourage walking and biking, it is essential to address safety concerns and improve infrastructure. This includes redesigning urban spaces to ensure that daily needs, such as jobs, education, healthcare, and recreation, are accessible within distances that can be safely covered by walking or biking. The development of green spaces, parks, and trails can also promote these active forms of transportation. Additionally, implementing secure parking for bikes near public transportation and workplaces can provide a convenient backup option for those who wish to combine active travel with other modes of transportation.
Furthermore, investing in public transportation infrastructure and services is crucial. By providing efficient and attractive public transportation options, such as buses and trains, more people can be encouraged to leave their cars at home, reducing the number of vehicles on the road and the overall emissions. Implementing low-emission zones and making electric vehicles more accessible are also strategies that can help reduce pollution from motor vehicles.
By driving less and choosing to walk or bike more, individuals can play a crucial role in reducing air pollution, improving their health, and contributing to the mitigation of climate change. It is a simple yet powerful step towards creating a more sustainable and healthier future for ourselves and generations to come.

Carpool or use public transportation
One of the best ways to reduce air pollution from motor vehicles is to drive less. If you can, try walking, biking, or scooting for shorter trips. This not only reduces air pollution but also makes individuals and communities healthier and more sustainable. It also reduces noise pollution and water runoff from road construction. Many cities and counties have community groups organized around active transportation, with classes and events to encourage biking and walking.
For longer distances, carpooling is an effective way to reduce the impact of your commute. Even driving with just one other person can reduce your annual carbon footprint by 2,000 pounds (1 ton) of CO2e or more. Carpooling can also save you time and money, as you may be able to use the HOV (High Occupancy Vehicle) lane.
Public transportation is another great way to reduce pollution. It produces lower emissions per passenger mile than private vehicles and continues to get cleaner with innovations like Transit Signal Priority (TSP) and the adoption of cleaner fuels. A single person who switches from a 20-mile solo commute by car to public transportation can reduce their annual CO2 emissions by 20 pounds per day, or more than 48,000 pounds in a year. Public transportation also reduces congestion and saves money compared to driving, with no need to pay for parking or fuel.
If you must drive, there are still ways to reduce your impact. Driving efficiently by observing speed limits, accelerating gradually, and avoiding hard braking can reduce fuel consumption and emissions. Maintaining your vehicle according to the owner's manual, including regular oil changes, can also keep it running as clean and efficiently as possible. When shopping for a new car, look for fuel-efficient vehicles with low greenhouse gas emissions.

Accelerate gradually, observe speed limits
Accelerating gradually and observing speed limits are effective ways to reduce pollution from your vehicle. When you accelerate rapidly, your vehicle uses more energy and fuel, increasing emissions and air pollution. By going easy on the gas pedal and gradually building up speed, you can reduce the amount of fuel consumed and lower your vehicle's emissions.
Observing posted speed limits is another way to reduce pollution. Driving faster burns more fuel and emits more pollutants into the atmosphere. Research has shown that in built-up areas, higher speeds lead to more frequent acceleration, deceleration, and braking, all of which contribute to increased air pollution. By adhering to speed limits, you can help reduce the incidence of these polluting events.
Additionally, driving at slower speeds has safety benefits, particularly in areas with higher pedestrian traffic. Lower speed limits in urban areas can reduce the risk of fatal accidents, especially those involving children and other vulnerable road users. While there may be concerns about increased pollution at lower speeds, the overall impact of reduced speeds on emissions is favourable when coupled with gradual acceleration and deceleration.
To further reduce pollution, it is beneficial to anticipate the road ahead and maintain a steady pace. Avoid aggressive acceleration and sudden braking, as these actions waste fuel and increase emissions. Try to maintain a smooth driving pattern and anticipate traffic flow to minimize the need for abrupt speed changes.
By combining gradual acceleration with adherence to speed limits, you can significantly reduce your vehicle's emissions and contribute to improved air quality. These simple driving habits can make a substantial collective impact on reducing pollution from motor vehicles.
