Air pollution kills
Despite the existence of laws such as the Clean Air Act, which gives the Environmental Protection Agency (EPA) the authority to regulate air pollutants, air quality continues to deteriorate. This is due in part to the challenges of embedding air quality standards in legislation and the lack of international consensus on air quality standards. Many countries' laws do not meet the World Health Organization (WHO) guidelines, which are designed to protect human health from the harmful effects of air pollution.
The impact of air pollution is felt disproportionately by vulnerable populations, including children with respiratory diseases, and low-income communities. The cost of air pollution to pediatric health and economic development is significant and cannot be ignored. Air pollution contributes to childhood lung diseases and exacerbates respiratory conditions such as asthma.
To address this critical issue, countries must prioritize the implementation of stringent air quality laws that comply with WHO guidelines. Pollution prevention and control strategies, such as those outlined in the Pollution Prevention Act (P2 Act), are crucial. This includes reducing or eliminating waste at the source, promoting the use of non-toxic substances, and implementing conservation techniques.
By taking decisive action and adopting comprehensive legislation, we can curb the deadly impact of air pollution and protect the health and well-being of millions of people worldwide.

It's the greatest environmental threat to public health
Air pollution is the greatest environmental threat to public health. According to a UNEP report, indoor and outdoor air pollution are "among the leading avoidable causes of diseases and death globally, and the world's largest single environmental health risk". It kills 7 million people a year, more than COVID-19. Air pollution is particularly harmful to vulnerable populations, including children with respiratory diseases, and it disproportionately affects women, children, the elderly, and low-income populations.
The Clean Air Act, enacted in 1970 and strengthened in 1990, has played a crucial role in improving air quality and protecting public health in the United States. It gave the federal government and the Environmental Protection Agency (EPA) the authority to regulate air pollutants and polluting industries, combat climate change, and enforce regulations that limit air pollution. The EPA has also implemented initiatives such as the Acid Rain Program, which has successfully reduced sulfur dioxide and nitrogen dioxide emissions.
Despite these efforts, air pollution remains a significant issue. Many countries lack comprehensive air quality laws, and even in countries with air quality legislation, the standards often do not meet the guidelines set by the World Health Organization (WHO). The challenge of implementing effective air quality standards lies in the social and economic choices that must be made to achieve those standards, as well as the lack of an international regime on air quality that could provide guidance to individual nations.
To address this global health crisis, countries need to prioritize the development and enforcement of ambitious air quality standards. This includes reducing pollution at its source, promoting the use of non-toxic substances, and implementing conservation techniques. By following the WHO guidelines and working together to address the root causes of air pollution, nations can improve public health outcomes and reduce the devastating impact of air pollution on our planet and its inhabitants.
Additionally, organizations like the NRDC play a crucial role in advocating for stronger protections and pushing back against loopholes that prioritize industry over public health. Citizen organizations and public advocacy efforts help ensure that elected officials and governments fulfill their legal responsibilities to combat air pollution and prioritize the well-being of their citizens.

It disproportionately affects vulnerable populations, including children
Air pollution is the greatest environmental threat to public health globally, and it disproportionately affects vulnerable populations, including children. According to the World Health Organization, air pollution increases the risk of certain diseases, such as lung cancer, heart disease, and acute respiratory infections. While this impacts people of all ages, babies, newborns, and young children are more at risk.
Children are more susceptible to air pollution because their bodies, organs, and immune systems are still developing. Exposure to air pollution at a young age can hinder lung growth and development, inhibit brain development, and increase the risk of conditions such as asthma, low birth weight, and respiratory infections. Children are also more physically exposed to air pollution because they are shorter and closer to the ground, where pollutants like dust and vehicle exhaust are more concentrated. They also breathe faster, taking in more air relative to their body weight. As a result, children walking on busy roads may be exposed to up to a third more air pollution than adults.
The impact of air pollution on children's health is a significant concern, with over 1,200 deaths in people under 18 years of age estimated to be caused by air pollution every year in EEA member and collaborating countries. In 2021, air pollution was the second leading risk factor for death among children under five, after malnutrition, with a total of 709,000 deaths linked to air pollution. Additionally, almost half of all deaths due to lower respiratory tract infections in children under five were caused by particulate matter from household air pollution.
The effects of air pollution on children are not limited to physical health but also extend to cognitive development. Studies have linked air pollution to decreased cognitive performance in children and suggested that poor air quality is especially dangerous to them. UNICEF-supported research found that children were exposed to higher levels of pollution, particularly while walking to school and on playgrounds, and that the impact of this pollution was more severe on them than on adults.
Therefore, it is essential to prioritize the reduction of air pollution to safeguard the health and well-being of children and other vulnerable populations. This can be achieved through legislation, such as the Clean Air Act, which empowers regulatory bodies to enforce standards and hold polluters accountable. By taking proactive measures and adhering to scientific guidelines, we can protect vulnerable populations from the detrimental effects of air pollution and ensure a healthier future for generations to come.

Existing legislation isn't enough
The World Health Organization (WHO) has established air quality guidelines that reflect a high degree of scientific consensus and are intended to protect human health from the harmful effects of air pollution. However, many countries' air quality laws do not meet these standards, and even in countries with air quality laws, most of them do not comply with WHO guidelines. This is due to a variety of social, economic, and political factors, as well as the lack of an international regime on air quality standards, which makes it challenging for public authorities to embed air quality standards in legislation.
While there have been some successes in reducing air pollution, such as the Clean Air Act in the United States, which has helped keep air clean, combat climate change, and protect public health, more needs to be done. The Clean Air Act, for example, is facing obstacles and pushback from industries trying to gut the legislation. Additionally, the Supreme Court's conservative majority has restricted the Environmental Protection Agency's (EPA) ability to limit climate pollution from power plants.
Furthermore, existing regulations and industrial resources focus on treatment and disposal rather than source reduction, which is a more desirable approach to waste management and pollution control. Pollution prevention involves reducing or eliminating waste at the source by modifying production processes, promoting the use of non-toxic substances, implementing conservation techniques, and reusing materials. By focusing on source reduction, we can more effectively address the issue of air pollution and protect public health and the environment.
To effectively curb air pollution, countries need to develop ambitious global air quality standards that comply with WHO guidelines and address the social, economic, and political factors that hinder progress. Additionally, there is a need for international cooperation and a unified approach to air quality standards, as well as a continued push for stronger protections and the closure of loopholes that favor polluting industries.

Stronger laws can reduce pollution and save lives
Air pollution is the single greatest environmental threat to public health worldwide. It is responsible for 7 million deaths per year, a greater number than the official death toll of COVID-19. Despite this, many countries still do not have laws governing air quality. This is partly due to the challenge of embedding air quality standards in legislation, which requires social and economic choices to be made. In addition, the absence of an international regime on air quality standards means that a variety of national laws may act as a barrier to adopting contemporary approaches.
The Pollution Prevention Act (P2 Act) of 1990 is another example of legislation that helps to reduce pollution. It requires the EPA to establish a source reduction program that collects and disseminates information, provides financial assistance to states, and implements other activities. Source reduction is more desirable than waste management and pollution control because it reduces or eliminates waste at the source by modifying production processes, promoting the use of non-toxic substances, and reusing materials.
The World Health Organization (WHO) has also developed air quality guidelines that countries can use to inform legislation and policy. While these guidelines are not binding, they are based on scientific consensus and are designed to protect human health from the harmful effects of air pollution. By following these guidelines, countries can ensure that their laws are effective in reducing pollution and protecting their citizens' health.
In addition to legislation, public advocacy and the courts play a crucial role in ensuring that governments fulfill their legal responsibilities and strengthen laws to reduce pollution. Citizen organizations, such as the NRDC, have successfully pushed for stronger protections and defended the integrity of existing laws, such as the Clean Air Act. By combining stronger laws with public advocacy and judicial action, we can make significant progress in reducing pollution and saving lives.
