To reduce gasoline consumption, individuals can adopt more sustainable transportation methods. This includes opting for walking, cycling, scootering, skateboarding, or e-biking for shorter distances. For longer distances or when weather conditions are unfavorable, individuals can utilize public transit, rideshare services, or electric rental options. Carpooling and trip-consolidation are also effective ways to reduce gasoline consumption by lowering the number of vehicles on the road.

Switching to electric vehicles is a significant step towards reducing air pollution. Electric vehicles produce zero tailpipe emissions, which helps lower air pollution and greenhouse gas emissions from the transportation sector. While the production and charging of electric vehicles can contribute to carbon pollution, especially with certain energy sources, overall, they are responsible for lower levels of greenhouse gases than gasoline-powered cars.

To further reduce gasoline consumption, individuals can also focus on improving their fuel efficiency. This includes maintaining proper tire pressure, reducing vehicle weight by removing unnecessary items, minimizing the use of air conditioning, and driving at or near the speed limit. Additionally, driving habits like smooth acceleration and braking, avoiding hard accelerations, and maintaining a safe distance from the vehicle ahead can also improve fuel efficiency.

By combining reduced gasoline consumption with a switch to electric vehicles, individuals can play a significant role in lessening air pollution, improving air quality, and reducing the health risks associated with harmful pollutants.

Improve energy efficiency at home and work

Improving energy efficiency at home and work is a great way to lessen air pollution. Homes and commercial buildings consume 40% of the energy used in the United States, so there is a lot of potential for improvement.

One way to improve energy efficiency is to reduce energy consumption. This can be achieved by making small changes, such as turning off lights and appliances when they are not in use, using energy-efficient light bulbs, and sealing cracks and leaks to improve insulation. Upgrading to more efficient appliances, such as ENERGY STAR-qualified products, can also help. Additionally, consider using a microwave instead of a stove, washing clothes in cold water, and turning down the thermostat on your water heater.

Another way to improve energy efficiency is to take advantage of local climate and site conditions. For example, designers can incorporate passive solar heating and cooling strategies, such as using cool roofs that reflect more light and absorb less heat, to reduce the energy needed for heating and cooling. If you're building a new home or remodeling an existing one, consider investing in energy-efficient design and construction techniques, such as advanced house framing, which improves energy efficiency in wood-framed houses.

Finally, completing a home energy evaluation can help identify specific measures to make your home more energy-efficient. This might include upgrading heating and cooling systems, installing programmable thermostats, and improving insulation and air sealing. By making these improvements, you can save money and reduce your impact on the environment.

Avoid idling and consolidate car trips

Automobile emissions are the leading cause of air pollution in the United States, with gasoline and diesel vehicles releasing harmful pollutants such as carbon monoxide and nitrogen oxides. As such, one of the most effective ways to reduce air pollution is to avoid unnecessary car trips.

If you live in a place with access to public transportation or ridesharing services, consider switching to walking, cycling, scootering, skateboarding, or e-biking to work. If you have control over your work schedule, you can also try to plan your trips during off-peak hours to avoid traffic congestion. This will help to reduce the amount of time that your car is idling, emitting pollutants, and wasting fuel.

If you do need to drive, there are still ways to consolidate your car trips. Try to plan your trips in advance and combine multiple short trips into one longer trip. You can also save time and reduce pollution by skipping the drive-thru and going inside instead, or by choosing longer time windows for deliveries so that delivery trucks can optimize their routes and avoid extra trips.

Another way to reduce air pollution from vehicles is to switch to an electric vehicle (EV). Electric vehicles produce zero tailpipe emissions and can significantly reduce air pollution and greenhouse gas emissions over the lifecycle of the vehicle. In addition, you can maintain your vehicle regularly, ensure that your tires are properly inflated, and stop at the click when filling up your fuel tank to avoid overfilling.

Create green spaces to improve air quality

Creating and maintaining green spaces in urban areas is an effective way to improve air quality and combat air pollution. Plants absorb gaseous pollutants and release clean oxygen into the atmosphere, thereby improving air quality. Trees and vegetation can reduce levels of harmful gases and particulate matter, such as carbon monoxide, nitrogen oxides, and sulphur dioxide, which are common air pollutants.

Urban green spaces act as oases or buffers, providing areas of higher air quality compared to their surroundings. They can also encourage behavioural changes, promoting healthier and more sustainable choices such as walking and cycling, which can further reduce air pollution by decreasing the use of gasoline-powered vehicles.

The positive impact of green spaces on air quality has been observed in various places. For example, an experiment in the French city of Strasbourg found that public trees reduced approximately 7% of PM10 in the city's atmosphere. Similarly, electric and plug-in hybrid vehicles in the US have contributed to reducing emissions, with policies supporting the adoption of electric vehicles playing a crucial role.

However, it is important to recognise that the effectiveness of urban green spaces in mitigating air pollution can be limited by factors such as the scale of implementation and maintenance. To maximise their impact, green spaces should be well-designed, attractive, accessible, and properly maintained. This requires addressing challenges like the costs of creating and maintaining green spaces in densely populated urban areas.

Overall, creating and maintaining green spaces in urban environments can be a valuable strategy to improve air quality and reduce air pollution, especially when complemented with other measures such as energy conservation and the use of energy-efficient power sources.

Use public transport, carpool, walk or cycle

As automobiles are the primary source of air pollution, opting for alternative means of transportation is crucial to reducing air pollution. This includes using public transportation, carpooling, walking, or cycling.

Public transportation, such as buses, trains, and subways, can significantly reduce air pollution by decreasing the number of cars on the road.
