Motor vehicles are a significant source of air pollution, emitting harmful pollutants and greenhouse gases that contribute to climate change. Vehicle emissions have become the dominant source of air pollutants in many areas, with traffic-related emissions responsible for air quality standard exceedances. To reduce car pollution, individuals can opt for fuel-efficient vehicles, maintain their cars, and drive efficiently. Electric vehicles, hybrid cars, and fuel-efficient gas cars are more environmentally friendly options. Regular car maintenance and efficient driving practices, such as avoiding unnecessary idling, can also reduce emissions. Additionally, seamless traffic management and urban design improvements can play a significant role in reducing traffic-related air pollution.

What You'll Learn
Maintain your car
Maintaining your car is essential to reducing its pollution output. Firstly, it is important to keep your car in good repair. This includes scheduling regular oil changes and other maintenance as outlined in your owner's manual. Newer vehicles have very complex emission controls, so it is important to ensure these are functioning as designed. If your check engine light comes on, take your vehicle to a qualified automotive technician for repairs or maintenance.
Keeping your tires properly inflated is another way to maintain your car's efficiency. You can find the correct tire pressure in your owner's manual. Properly inflated tires make your vehicle burn less fuel and run more efficiently. This is another way to maintain your car and reduce its pollution output.
Regular maintenance and servicing of your car can also help to reduce emissions. Accumulated debris and dust can cause your car to produce more emissions, so seasonal or regular servicing is important to prevent this. Servicing your car also increases its longevity, so you won't need to replace it as soon.
Another way to maintain your car is to avoid idling. Idling wastes fuel and causes excess engine wear. Modern vehicles do not need to be warmed up in winter, so there is no need to turn on the engine until you are ready to drive. When waiting for long periods in traffic or at a red light, turn off your engine to reduce emissions.

Drive efficiently
Driving efficiently is a key way to reduce car pollution. Here are some tips to drive more efficiently:
Firstly, be mindful of your acceleration and braking. Aggressive acceleration increases fuel consumption and emissions. Try to accelerate gently and smoothly, and avoid heavy braking by leaving a greater distance between you and the car in front. This will also make your driving safer.
Secondly, try to maintain a constant speed. This is more efficient than constantly accelerating and decelerating, and modern vehicles are designed to run optimally within a certain speed range, usually between 45 and 65 miles per hour. Observing speed limits will also help you achieve this, and is safer.
Thirdly, avoid idling. Modern vehicles do not need to be warmed up in winter, so only turn on the engine when you are ready to drive. Idling wastes fuel and causes excess engine wear, and the emissions are more concentrated at ground level, which is worse for people's health.
Finally, keep your tires properly inflated. This will make your vehicle more efficient and burn less fuel. Check your owner's manual for the correct tire pressure.

Choose fuel-efficient vehicles
Choosing fuel-efficient vehicles is one of the most effective ways to reduce car pollution. Electric, hybrid, and even compact fuel-efficient gas vehicles are all options to consider when looking for a fuel-efficient car. While the initial cost of some of these vehicles can be high, prices are becoming more affordable as they become more common.
When shopping for a new car, look for vehicles with low greenhouse gas emissions. Cleaner-burning gasoline vehicles, for example, are a good option. You can use the EPA's Green Vehicle Guide to learn about vehicles that are more efficient and less polluting. The EPA's Fuel Economy and Environment Label is another useful tool to compare different vehicle models and find the most fuel-efficient and environmentally friendly vehicle that meets your needs. This information is also available on the joint DOE and EPA website, fuel economy.gov.
If your job or lifestyle requires a larger vehicle, you can still compare the fuel economy of the available options and choose the most efficient one. Driving the most efficient vehicle you can get reduces pollution and saves you money.
In addition to choosing a fuel-efficient vehicle, there are other things you can do to reduce car pollution. Properly maintaining your vehicle and keeping it in good repair is important. Follow your owner's manual and schedule regular oil changes and other maintenance. Keeping your tires properly inflated also makes your vehicle more efficient and reduces fuel consumption.

Use alternative fuels
Using alternative fuels is a great way to reduce car pollution. Alternative fuels are any fuels or power sources that can be used instead of fossil fuels for transport, helping to decarbonize the sector.
Electricity is one of the most common alternative fuels, used to power electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). While the initial cost of these vehicles can be high, prices are becoming more affordable as they become more common. Most new electric vehicles now have a range of over 100 miles, which meets most people's daily commuting needs. However, the changeover to electric vehicles would require billions of batteries, and the availability of resources for their sustainable use is often questioned.
Another alternative fuel is ethanol, a renewable fuel made from crops such as corn. Flex-fuel vehicles can use ethanol blends that are up to 85% ethanol, while regular cars newer than 2001 can use blends with up to 15% ethanol. Ethanol is a widely used alternative fuel that helps support American farmers.
Hydrogen is another alternative fuel that is often used for heavy-duty road vehicles. Hydrogen is extracted from water or organic compounds and has the potential to contribute to a substantial reduction in overall CO2 emissions, as its only by-products are water and nitrogen. However, hydrogen is still in its early stages of development and requires massive amounts of the gas, which is difficult to produce and handle.
Biofuels are also an option for existing vehicles, as they can be manufactured from vegetable oils, animal fats, or recycled cooking grease for use in diesel vehicles. However, procuring the required amounts of feedstock and mitigating food-versus-fuel issues remain challenges for the widespread use of biofuels.
By using alternative fuels, individuals and governments can help improve efficiency, cut costs, and reduce emissions from the transport sector.

Support public transport
Supporting public transportation is a highly effective way to reduce car pollution. Firstly, public transportation has a proven record of reducing congestion. Research shows that in 2011, the use of public transportation in the US saved 865 million hours in travel time. Without this, congestion costs in 2011 would have increased by a massive $21 billion.
Reducing congestion is directly linked to reducing pollution. When there is less congestion, there are fewer cars on the road, and therefore less vehicle pollution. This is supported by the fact that public transportation in the US saves 37 million metric tons of carbon dioxide annually. This is the same as the emissions from the electricity generated for use in almost 5 million households.
Additionally, when individuals opt for public transportation over driving, they are often choosing a cleaner mode of transport. For example, 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 48,000 pounds in a year. This is a significant reduction in emissions, and it is equivalent to a 10% reduction in greenhouse gases produced by a typical two-adult, two-car household.
Public transportation also encourages the use of alternative fuels. For instance, buses are increasingly using compressed natural gas (CNG) instead of diesel fuel. This move from diesel to CNG fuel creates cost savings and environmental benefits. KCATA, for example, has reduced its greenhouse gas emissions by 1,870 metric tons through the use of CNG.
Finally, by supporting public transportation, individuals are incentivized to drive less and walk, bike, or carpool more. This inherently reduces car pollution as there are fewer cars on the road.
