• The EPA has worked with state, local, and tribal governments, as well as other agencies and stakeholders, to implement the Clean Air Act and reduce air pollution.

Health Benefits:

• The reduction in air pollution has led to dramatic improvements in air quality. From 1990 to 2020, there were significant improvements in the national concentrations of several pollutants: carbon monoxide (73% improvement), lead (86% improvement), annual nitrogen dioxide (61% improvement), ozone (25% improvement), 24-hour coarse particle concentrations (26% improvement), annual fine particles (41% improvement), and sulfur dioxide (91% improvement).
• These improvements have enabled many areas to meet national air quality standards, protecting public health. For example, all areas with unhealthy levels of carbon monoxide in 1991 now meet the health-based standards.
• The Clean Air Act has helped reduce the risk of premature death, respiratory problems, and other health issues for Americans. A 2011 EPA study estimated that in 2020 alone, the Act avoided more than 2,300,000 premature deaths, prevented millions of cases of respiratory problems, and kept children healthy and in school.
• The Act has also addressed toxic air pollutants, which can cause cancer and other serious health issues. EPA standards and initiatives have successfully reduced emissions of hazardous air pollutants from diverse sources, including industrial facilities, motor vehicles, and small "area" sources.

Economic Benefits:

• The Clean Air Act has proven to be a good economic investment. Multiple studies show that the public health and environmental benefits of the Act far exceed the costs of achieving them. The 2011 EPA study estimated that the benefits of clean air programs established by the 1990 amendments would exceed compliance costs by a factor of more than 30-to-1.
• Cleaner air leads to improved economic welfare and growth rates. Reduced air-pollution-related illnesses result in lower medical expenses and higher worker productivity, contributing to a stronger economy.
• The Act has also created market opportunities and encouraged innovation in cleaner technologies, with the US becoming a global market leader in this sector.

Environmental Benefits:

• The Clean Air Act has helped reduce environmental damage caused by air pollution. Lower pollution levels mean less harm to ecosystems, crops, and timber yields.
• The Act has also contributed to clearer scenic vistas in national parks due to reductions in pollution-caused haze.
• Additionally, actions taken under the Act to protect the stratospheric ozone layer are saving millions of people from skin cancers and cataracts.

Reducing air pollution is a universally acknowledged goal

The Clean Air Act has played a significant role in reducing air pollution over the past 45 years, cutting down on six common pollutants: particles, ozone, lead, carbon monoxide, nitrogen dioxide, and sulfur dioxide. The Act has also addressed numerous toxic pollutants, and new cars, trucks, and non-road engines are now equipped with state-of-the-art emission control technologies. Additionally, new plants and factories are required to install modern pollution control technology, and power plants have significantly reduced emissions that cause acid rain and harm public health.

To further reduce air pollution, individuals can take several actions in their daily lives. Conserving energy, carpooling, using public transportation, biking, or walking whenever possible are effective ways to reduce pollution. Properly maintaining car engines and keeping tires inflated can also help. Using environmentally safe paints and cleaning products, mulching or composting leaves and yard waste, and opting for gas logs instead of wood are other simple yet impactful actions.

On days with high ozone or particle levels, taking additional steps such as choosing a cleaner commute, reducing trips, avoiding idling, and deferring the use of gasoline-powered equipment can make a significant difference.

While reducing air pollution is a widely recognized goal, it is important to acknowledge the challenges and complexities involved. For instance, fuel changes may not always lead to significant reductions in nitrogen oxide emissions and, consequently, ozone production. Additionally, shutting down a power source may increase emissions from other sources to meet demands. Therefore, a comprehensive approach that considers various factors is necessary to achieve the goal of reducing air pollution and protecting public health and the environment.

In addition to vehicle emissions, the EPA addresses pollution from industrial sources. Power plants, for example, are required to install modern pollution control technology, such as devices that capture sulfur dioxide and nitrogen oxide emissions. The EPA has also taken steps to limit emissions from aircraft, locomotives, and marine vessels. By working with governments and industries, the EPA ensures that new and existing power plants meet the required standards.

The EPA's partnership programs play a crucial role in reducing air pollution. These voluntary programs complement regulatory efforts and involve collaboration with various sectors. For example, the SmartWay program empowers companies to adopt cleaner and more energy-efficient practices for transporting goods, resulting in significant emissions reductions. The Diesel Emissions Reduction Act (DERA) is another example, providing funding for owners to replace their diesel equipment, leading to reduced nitrogen oxide and particulate matter pollution.

Furthermore, the EPA provides support and resources to local communities. The agency offers guidance and incentives to reduce air pollution, including programs for businesses, cities, nonprofits, and communities. This includes initiatives such as the National Clean Diesel Campaign and Clean School Bus USA, which aim to minimize pollution from diesel engines and school buses, respectively. The EPA also encourages the use of electric or hand-powered lawn equipment and promotes energy conservation through the Energy Star label.
