Heroes Fighting To End Air Pollution

Air pollution is a critical global health issue, causing millions of premature deaths annually. It is caused by mobile and industrial sources, as well as neighbourhood activities, and affects people in low-, middle-, and high-income countries. The World Health Organization (WHO) has developed global air quality guidelines (AQG) to address this issue, and governments, independent organizations, and individuals are working to reduce air pollution through various means. This includes implementing clean air programs, passing local ordinances, creating incentives, educating residents, and adopting environmentally friendly practices in daily life.

Individuals: reduce car usage, switch to electric, use less energy

Individuals can play a significant role in reducing air pollution by adopting simple measures in their daily lives. One of the most effective ways to achieve this is by reducing car usage. Cars, especially those with diesel engines, contribute significantly to air pollution. By opting for alternative modes of transportation, such as walking, biking, or using public transportation, individuals can substantially decrease their carbon footprint. Carpooling and ride-sharing are also excellent ways to reduce the number of vehicles on the road and, consequently, the amount of pollutant emitted.

Switching to electric vehicles is another powerful way to combat air pollution. Electric cars produce zero emissions, which is particularly beneficial for improving air quality in disadvantaged communities, often comprising people of colour and lower-income groups. These communities are often disproportionately affected by air pollution. While electric vehicles are a step in the right direction, it is important to note that the benefits are limited unless they are paired with a clean source of power, such as hydroelectric or solar energy. This is because the source of electricity must also be clean for electric vehicles to be truly environmentally beneficial.

In addition to reducing car usage and switching to electric, individuals can make a substantial impact by using less energy at home. Household air pollution can be mitigated by adopting cleaner technologies and fuels for cooking, heating, and lighting. For instance, electric stoves, including lower-cost induction cookers, are much cleaner than traditional stoves when paired with a clean electricity supply. In areas with ample wind or sunlight, solar stoves and micro-grids powered by renewable energy sources can be utilised for cooking and powering electrical appliances. Furthermore, strategic placement of windows, insulated walls, and reflective roofs can reduce the demand for space heating, leading to reduced energy consumption and lower emissions.

Behavioural changes can also contribute significantly to reducing household air pollution. Simple actions such as opening windows and doors while cooking or cooking outside can reduce exposure to harmful pollutants. Additionally, ensuring proper ventilation in households by installing chimneys or hoods can mitigate indoor air pollution, although it is important to note that vented smoke can re-enter the home and contribute to outdoor air pollution. Therefore, combining ventilation with cleaner fuels and low-emission stoves is essential for optimal results. Marginalised groups, who are often disproportionately affected by air pollution, can be empowered through education and awareness campaigns to make informed choices and drive community action for improved air quality.

Businesses: comply with environmental rules, reduce waste and emissions

Businesses play a crucial role in reducing air pollution and improving air quality. By complying with environmental rules and regulations, businesses can significantly reduce their carbon footprint and contribute to a cleaner, healthier environment.

In the United States, the Environmental Protection Agency (EPA) creates and enforces environmental regulations for businesses. These regulations aim to reduce air pollution, waste, and emissions, protecting both the environment and public health. For example, the EPA's Clean Air Act requirements for the oil and natural gas industry help reduce emissions of harmful air pollutants, including volatile organic compounds (VOCs) that contribute to ground-level ozone and hazardous air pollutants like mercury. Additionally, the EPA has implemented CO2 emission standards for commercial aviation and large business jets, consistent with international standards.

To comply with environmental rules, businesses should be aware of federal, state, and local laws and regulations. For instance, the Resource Conservation and Recovery Act (RCRA) establishes a comprehensive program for managing hazardous waste, while the Toxic Substances Control Act (TSCA) gives the EPA authority over certain toxic materials. The National Emission Standards for Hazardous Air Pollutants (NESHAP) program, meanwhile, focuses on reducing asbestos exposure during renovations, demolitions, and waste disposal. Businesses that perform incineration, chemical manufacturing, glass manufacturing, or metal processing operations are likely to be subject to specific regulations due to the release of small air pollution particles.

By complying with these regulations, businesses can avoid fines and sanctions while also improving their public image and qualifying for special incentives. For example, companies that install renewable energy systems to meet emissions requirements may receive tax breaks. Additionally, environmental compliance can lead to cost reduction, improved efficiency, and a better brand image, as customers, investors, and potential employees often favour environmentally conscious companies.

Furthermore, businesses can actively reduce waste and emissions through various initiatives. This includes reducing energy consumption, choosing sustainable products, and limiting the use of toxic chemicals. Implementing recycling programs, encouraging double-sided printing, and turning off equipment when not in use are simple yet effective measures. Additionally, companies can promote sustainable practices among their partners, suppliers, and contractors, further extending their positive impact.

Governments: pass local ordinances, incentivise good behaviours, educate residents

Governments play a crucial role in combating air pollution through various measures, including passing local ordinances, incentivising good behaviours, and educating residents. Here are some ways governments can address air pollution:

Passing Local Ordinances

Local governments can implement air pollution management plans to improve air quality in their communities. This includes holding industries such as agriculture, transportation, construction, and manufacturing accountable for adhering to environmental laws and reducing their pollution levels. For example, local governments can enforce the use of modern pollution control technology in new plants and factories, as seen through the Clean Air Act in the United States.

Incentivising Good Behaviours

Incentives can be offered to local businesses to encourage environmentally friendly practices and reduce their carbon footprint. For instance, the Minnesota Pollution Control Agency provides incentives for businesses, cities, nonprofits, and communities to address environmental issues, including air quality. Governments can also incentivise residents to adopt cleaner transportation options, such as prioritising walking, biking, or using public transit, and offering incentives for purchasing electric vehicles.

Educating Residents

Education is a powerful tool for empowering residents to take action against air pollution. Governments can raise awareness about the impacts of air pollution and provide guidance on simple actions that can collectively make a significant difference. For example, residents can be encouraged to reduce car usage, carpool, or maintain their vehicles to reduce emissions. Additionally, education can focus on the benefits of electric vehicles and the importance of reducing idling, as idling engines contribute to harmful pollution levels.

Furthermore, governments can promote the positive impact of planting and caring for trees in local communities, as trees act as natural air filters and help absorb carbon dioxide. Educating residents about the dangers of backyard fires in urban areas and encouraging alternative methods during air quality alerts can also mitigate air pollution.

By passing local ordinances, incentivising good behaviours, and educating residents, governments can effectively contribute to the global effort to reduce air pollution and improve the health and well-being of their citizens.

Policy-makers: support cleaner transport, energy-efficient homes, better waste management

Policy-makers play a crucial role in driving the transition to cleaner transportation, promoting energy-efficient homes, and improving waste management practices to combat air pollution.

Cleaner Transportation

Policy-makers are instrumental in pushing for cleaner transportation options. This includes supporting the development and adoption of zero-emission vehicles, such as electric cars and trucks. For example, TRC Companies has secured over $1 billion in grants and funding for clean transportation projects, including the "Electrify the Empire State" initiative, which aims to deploy 38 electric medium- and heavy-duty vehicles in underserved communities in New York. Additionally, public policies and financial incentives are encouraging transportation companies to transition to new power technologies and move away from diesel engines.

Energy-Efficient Homes

Policy-makers can also promote energy-efficient homes by providing resources and guidelines for homeowners and builders. The U.S. Department of Energy recommends conducting a home energy assessment to identify areas where energy use can be reduced, such as through advanced house framing, cool roofs, passive solar design, and energy-efficient landscaping. Policy-makers can further incentivize the use of renewable energy systems, such as solar water heating and electricity, to reduce a home's environmental footprint.

Better Waste Management

Proper waste management is crucial in reducing air pollution. Policy-makers can establish strong regulations to prevent open dumping and burning of waste, which releases harmful substances into the air. Instead, promoting recycling, composting, and safe waste treatment methods can help maintain clean air and protect public health. Additionally, policy-makers can assist local waste management teams in improving their practices, ensuring safer working conditions for waste workers and reducing the release of harmful chemicals into the air and water.

By implementing policies that support cleaner transportation, energy-efficient homes, and better waste management, policy-makers can significantly contribute to improving air quality and mitigating the health risks associated with air pollution. These initiatives are essential to protecting the environment and ensuring a sustainable future for generations to come.

International organisations: provide toolkits, set guidelines, promote gradual change

International organisations play a pivotal role in combating air pollution by providing toolkits, establishing guidelines, and advocating for gradual change. Their efforts are directed towards mitigating the severe health risks posed by poor air quality, which claims millions of lives annually and disproportionately affects vulnerable and marginalised communities.

One prominent organisation, the World Health Organization (WHO), has developed Global Air Quality Guidelines (AQGs) to address the detrimental effects of air pollution on human health. These guidelines, last updated in 2021, provide clear evidence of the harm caused by air pollution, even at lower concentrations than previously understood. By recommending new air quality levels, the guidelines aim to protect populations from key air pollutants, many of which contribute to climate change. WHO's guidelines also offer practical strategies for managing specific types of particulate matter, such as black carbon and ultrafine particles. Recognising the challenges in achieving recommended air quality levels, WHO proposes interim targets to facilitate stepwise improvements, thereby gradually improving public health.

The Clean Air Fund, a philanthropic initiative, collaborates with governments, funders, businesses, and campaigners to address global air pollution. They provide grants, scholarships, technical assistance, and training materials to local community groups, empowering them to drive change. Additionally, the Clean Air Fund offers the only global analysis of international development funding for tackling air pollution, highlighting funding trends and providing recommendations for governments and development finance institutions. Their work extends to promoting air quality data, raising public awareness, and influencing policymaking to accelerate progress towards cleaner air.

Another notable organisation, the Clean Air Task Force (CATF), is a US-based non-profit that has been working since 1996 to reduce air pollution, protect public health, and mitigate climate change. CATF collaborates with federal and state partners, research institutions, and industry leaders to develop policy solutions and strategies that improve air quality on a global scale. Their efforts demonstrate the power of collaboration in tackling this pressing issue.

In addition to these initiatives, other international organisations are making significant contributions. For example, the Clean Air Society of Australia and New Zealand (CASANZ) is a non-profit dedicated to improving air quality and promoting public health and well-being. CASANZ achieves this through education, advocacy, research, and policy recommendations, utilising workshops, conferences, and dialogues with policymakers to drive change. Similarly, Future Cleantech Architects (FCA) seeks to find innovative solutions to climate change and air pollution by bringing together experts from various sectors to work on creative technology solutions. FCA aims to make clean tech accessible everywhere, fostering healthier cities with cleaner air.

Through their toolkits, guidelines, and promotion of gradual change, these international organisations provide essential leadership and support in the global fight against air pollution, ensuring that communities worldwide can breathe healthier air and mitigate the harmful impacts of air pollution on human health and the environment.
