Social Solutions To Clean Our Air

Air pollution is a pressing issue that poses a significant threat to human health and the planet. According to the World Health Organization (WHO), approximately 99% of people worldwide breathe air that exceeds the recommended guideline limits for pollutants, leading to about seven million premature deaths annually. While air pollution affects everyone, it disproportionately impacts marginalized and low- to middle-income communities. Society plays a crucial role in addressing this issue through various initiatives and interventions. For instance, community-led organizations, such as the Clean Air Fund, work alongside governments and agencies like the United States Environmental Protection Agency (EPA) to implement policies and programs aimed at reducing air pollution and mitigating its harmful effects. These efforts include adopting cleaner technologies, improving energy efficiency, regulating emissions, and raising awareness about the risks associated with air pollution.

Marginalised communities are disproportionately affected by air pollution

Socioeconomic status plays a significant role in the impact of air pollution on marginalised communities. Multiple studies have shown that low-income communities bear the brunt of polluted air. They are often the least responsible for harmful emissions but suffer the most exposure in their daily lives. For example, a 2008 study of Washington, DC, found a positive correlation between poverty and worsened asthma due to poor air quality. Additionally, children under five living in lower-income countries are 60 times more likely to die from air pollution.

Racial and ethnic disparities also contribute to the disproportionate impact of air pollution on marginalised communities. People of colour and minority groups are more likely to reside in areas with heavy pollution and face higher exposure to pollutants. Studies have found that African Americans and Hispanics have a higher risk of premature death from particle pollution compared to whites, even when controlling for income. This suggests that factors such as chronic stress due to discrimination may play a role in the increased health risks faced by these communities.

Unequal access to resources and support further exacerbates the issue. Marginalised communities often lack access to basic environmental resources and face discrimination in environmental policymaking and implementation. Additionally, pollution sources tend to be located near disadvantaged communities, increasing their exposure to harmful pollutants.

The intersection of these factors creates a cycle where marginalised communities are disproportionately affected by air pollution and face greater health risks and impacts. While some efforts are being made to address these disparities, such as President Biden's focus on environmental justice and investments in disadvantaged communities, much more needs to be done to ensure equal protection and access to a clean and healthy environment for all.

The Clean Air Act helps regulate harmful air pollutants

The Clean Air Act (CAA) is a comprehensive federal law that gives the Environmental Protection Agency (EPA) the authority to regulate air pollutants and polluting industries. The Act was established in 1970 and has been amended several times since then, with the most recent amendment being made in 2022. The EPA works with state, local, and tribal governments, other federal agencies, and stakeholders to reduce air pollution and protect public health and welfare.

One of the key roles of the EPA under the Clean Air Act is to establish National Ambient Air Quality Standards (NAAQS) to protect public health and welfare and regulate emissions of hazardous air pollutants. These standards set levels of pollution that are deemed safe over different periods. The EPA also issues federal emissions standards for new motor vehicles and non-road engines, as well as national emissions standards for categories of new industrial equipment, such as power plants and industrial boilers.

The Clean Air Act has been instrumental in reducing air pollution in the United States. Since 1990, there has been an approximate 50% decline in emissions of key air pollutants. The Act has also helped to improve air quality in communities, especially those that are marginalized and disproportionately affected by air pollution. The EPA encourages and supports area-wide air toxics strategies through initiatives such as the National Clean Diesel Campaign, Clean School Bus USA, and the SmartWay Transport Partnership.

The Clean Air Act also addresses emerging pollution threats and works to combat climate change. The 2022 amendment to the Act reinforced that carbon dioxide emitted from fossil fuels is an air pollutant and that the EPA has the authority and responsibility to regulate it. This amendment also provided new funding, including grants and incentives, to help industries, states, and localities make deeper pollution cuts.

The EPA has helped reduce toxic air pollution

The United States Environmental Protection Agency (EPA) has been instrumental in reducing toxic air pollution. Since 1970, the EPA has set and implemented emissions standards to control pollution from passenger vehicles, heavy-duty trucks and buses, and construction. The Clean Air Act, established in 1970, authorises the EPA to regulate the emissions of harmful air pollutants to safeguard public health.

The EPA has been successful in reducing toxic air pollution through various initiatives. Firstly, they have set standards for carbon emissions from passenger cars, trucks, and buses, and are now working to develop standards for aircraft. The EPA has also been successful in phasing out lead in gasoline, resulting in a 94% decrease in lead levels in the air between 1980 and 1999.

Furthermore, the EPA has issued emissions standards for 174 categories of major sources, such as chemical plants and oil refineries, and 68 categories of small "area" sources, representing 90% of the worst urban toxic pollutants. The EPA has also proposed measures to cut methane emissions and reduce smog-forming air pollution, particularly targeting the oil and gas industry.

In addition to these initiatives, the EPA has implemented the Mercury and Air Toxics Standards for power plants, requiring them to reduce emissions of mercury and other toxic pollutants. This has protected Americans from illnesses and premature deaths associated with these pollutants, such as asthma and other respiratory diseases.

The EPA has also helped states meet standards for common pollutants by issuing federal emissions standards for new motor vehicles and non-road engines, as well as providing technical and policy guidance for state implementation plans. Overall, the EPA's efforts have significantly improved air quality and public health in the United States.

WHO raises awareness about the risks of air pollution

Air pollution is responsible for nearly seven million deaths worldwide each year, according to the World Health Organization (WHO). Ninety-nine per cent of people currently breathe air that exceeds the WHO's guideline limits for pollutants, with those in low- and middle-income countries suffering the most.

WHO's Air Quality and Health Unit works in three cross-cutting areas: knowledge, evidence and measuring progress; institutional capacity building and technical support; and leadership and coordination. The organization has also developed and implemented a strategy for raising awareness about the risks of air pollution and the solutions that can mitigate exposure.

Through its BreatheLife campaign, WHO has increased the political commitment of policymakers to lead urban, national and regional campaigns to build awareness of the health impacts of air pollution. The campaign has also helped to scale up local policy interventions and anchor health as a lever for action on climate change.

The campaign supports WHO's awareness-raising strategy through a global communications platform that visualizes WHO's data in combination with web content to drive forward the global story of air pollution. It also provides an online space for members to share experiences, challenges and best practices for local governance, and for promoters to share tools and resources for implementing solutions.

The global Health and Energy Platform of Action (HEPA) is another initiative that aims to improve the health and livelihoods of the poorest populations through the adoption of clean and sustainable energy. With an initial focus on clean cooking and healthcare facility electrification, the platform aims to catalyse the scale of results required to achieve health, energy, gender and climate goals.

Individuals can use tools to monitor air quality and protect themselves

Individuals can take an active role in monitoring air quality and protecting themselves from the harmful effects of air pollution. While air pollution is often thought of as an outdoor issue, it is important to remember that indoor air quality can also be poor and have negative health impacts.

There are several tools and strategies that individuals can use to monitor and improve air quality. Firstly, individuals can utilise mobile applications such as the Environmental Protection Agency's AirNow app, which provides real-time air quality data. This app offers information on the current air quality index (AQI) and can help individuals make informed decisions about their exposure to outdoor air pollution. For example, if the AQI is poor, individuals can choose to stay indoors with windows and doors closed to minimise their exposure.

Additionally, individuals can invest in low-cost air pollution monitors for their homes. These devices have become increasingly accessible and can provide valuable insights into indoor air quality. They can detect specific pollutants and environmental factors, such as particulate matter, temperature, and humidity, and help individuals identify when to take action to improve the air they breathe. For example, if a monitor indicates high levels of particulate matter, one can use an air purifier or install HVAC filters to reduce these pollutants.

Personal air quality monitors are another option for individuals who want real-time data on the go. These portable devices can be carried on a keychain or necklace and measure air quality wherever one travels. While some reviews suggest that these devices may have connectivity issues and inaccurate readings, they can still offer a general indication of air quality when combined with other sources of information, such as AQI apps.

Furthermore, individuals can take proactive measures to improve the air quality in their immediate surroundings. For example, if there is a lot of traffic pollution in the area, one can choose to walk or cycle instead of driving, thus reducing their contribution to local air pollution and also minimising their exposure to exhaust fumes. Additionally, when indoor air quality is good, briefly opening windows and doors can help ventilate and flush out any built-up pollutants, creating a healthier living environment.

By utilising these tools and strategies, individuals can actively monitor and improve the air they breathe, protecting their health and contributing to a collective effort to reduce the impact of air pollution.
