What You'll Learn
Stricter vehicle emission standards
The transportation sector is the largest direct source of U.S. greenhouse gas emissions, with cars and light-duty trucks responsible for 57.5% of transportation emissions. Medium- and heavy-duty vehicles, including tractor-trailers, large pickups and vans, delivery trucks, buses, and garbage trucks, produce about 26% of transportation emissions.
To enforce stricter vehicle emission standards and decrease pollution, governments can implement the following measures:
Incentivize the Adoption of Electric Vehicles
Governments can provide financial incentives, such as subsidies or tax breaks, to encourage the purchase of electric vehicles (EVs). This can be coupled with voluntary targets for automakers to increase EV sales and production. For example, leading U.S. automakers like Ford, General Motors, and Stellantis have set targets to make 40-50% of their sales electric by 2030.
Establish Stringent Emission Regulations
Governments can set mandatory emission standards for vehicles, specifying the permissible levels of pollutants such as nitrogen oxides (NOx) and sulphur oxides (SOx). These regulations can be based on vehicle weight and cargo capacity, with stricter standards for heavier vehicles that typically emit more pollutants. California, for instance, has implemented the Low-Emission Vehicle (LEV) program, which defines six automotive emission standards stricter than the U.S. national Tier regulations.
Promote Public Transportation and Active Commuting
Encouraging the use of public transportation, such as buses and trains, can help reduce vehicle emissions. Additionally, promoting active commuting options like biking or walking can further decrease pollution and improve air quality.
Regular Vehicle Maintenance and Inspection
Governments can mandate regular vehicle maintenance and inspection programs to ensure that vehicles meet emission standards. This includes checking for proper tyre pressure, as under-inflated tyres can lower fuel efficiency and increase emissions.
Educate the Public on Pollution Prevention
Educational programs can raise awareness about the impact of vehicle emissions and provide guidance on pollution prevention. This includes simple measures such as carpooling, keeping vehicles well-maintained, and avoiding idling engines, which create hotspots of pollution.

Incentivising the use of electric vehicles
Electric vehicles (EVs) are an important part of the solution to decreasing pollution. They are a more environmentally friendly alternative to traditional cars, as they do not produce emissions from burning gasoline or diesel.
To encourage the use of electric vehicles, governments and organizations can offer a range of incentives. These incentives can be targeted at both commercial and non-commercial vehicle owners to promote the 'electrification' of their fleets. For example, in the United States, privately owned cars and vans are responsible for a significant proportion of transportation-related emissions. Therefore, incentives that encourage the adoption of EVs over traditional internal combustion engine vehicles (ICEVs) can offer substantial carbon emissions reduction opportunities.
One such incentive is the provision of rebates and tax deductions. Many states in the US offer these to make the transition to electric vehicles more financially attractive. For instance, California offers rebates of up to $7,500 for new and leased zero-emission vehicles, including electric, plug-in hybrid, and fuel cell vehicles. Similarly, the Clean Cars 4 All (CC4A) initiative provides incentives for lower-income consumers to replace their old, polluting vehicles with newer, cleaner transportation options.
In addition to rebates, some electricity providers offer discounted rates for EV owners. For example, Alabama Power offers a discounted time-of-use rate for those who lease or own an EV or plug-in hybrid. The Chugach Electric Association provides a similar incentive, offering a $200 bill credit per residential charger. Furthermore, certain states allow EV drivers to use the High Occupancy Vehicle (HOV) lane, regardless of the number of occupants in the vehicle. This incentive can help reduce travel times for those choosing to drive EVs.
While these incentives are important, it is also crucial to consider the behavioural characteristics of EV adopters. The environmental effectiveness of these incentives depends on how, when, and by whom the EVs are used. Therefore, it is essential to educate EV owners on best practices to ensure that the incentives achieve the desired emissions reduction outcomes.

City planning to reduce exposure
City planning is a crucial aspect of reducing pollution exposure in urban areas. Here are several strategies that can be employed to achieve this:
Incorporate Greenery and Urban Gardens: Urban gardens and green spaces can significantly improve air quality by absorbing pollutants and releasing oxygen. This approach, known as urban greening, has been effective in cities like Phoenix, Arizona, where increased tree coverage and vegetation have helped cool urban heat islands and reduce the need for energy-intensive air conditioning. Urban gardens that provide food to local residents can also reduce transportation needs and associated emissions.
Address Transportation and Traffic Congestion: Transportation is a significant contributor to air pollution in cities, with vehicle emissions releasing nitrogen dioxide and particulate matter. To mitigate this, cities can encourage the use of public transportation, bicycles, and electric vehicles. Implementing subway systems and establishing incentives for carpooling or using low-emission vehicles can also help reduce traffic congestion and lower air pollutant levels.
Relocate Sensitive Infrastructure: Local governments can utilize air quality data to guide city planning decisions, ensuring that sensitive infrastructure such as housing developments, hospitals, and schools are located away from areas with high pollution levels, such as freeways. This proactive planning can help protect residents, especially children and the elderly, from the harmful effects of air pollution.
Implement Air Filtration Systems: Cities can require the installation of commercial high-efficiency air filtration systems in homes and buildings located in polluted areas. Los Angeles, for example, deployed teams to inspect buildings and ensure they were outfitted with proper air filters to protect residents from pollutants. Local governments can also provide funding for these filtration systems, improving indoor air quality and reducing exposure to harmful pollutants.
Educate and Engage the Community: City planning should also involve educating and engaging residents in pollution reduction efforts. This includes providing guidance and incentives for businesses and communities to reduce emissions, promoting sustainable practices, and encouraging residents to report elevated air pollution levels. By involving the community, cities can foster a collective sense of responsibility for improving air quality and reducing pollution exposure.
