Air Pollution: Who's At Risk And Why?

Air pollution is a global issue that affects everyone, regardless of location or income level. It is caused by various sources, including household combustion devices, vehicles, industrial facilities, and forest fires, and has detrimental effects on both human health and the planet. According to the World Health Organization (WHO), air pollution is responsible for approximately seven million deaths worldwide each year, with those in low- and middle-income countries suffering the most. The pollutants released into the air can cause respiratory and other diseases, and are major sources of morbidity and mortality. As a result, air pollution has become a public health emergency, and addressing it has become a priority for governments and organizations worldwide.

Everyone is affected by air pollution, whether they realise it or not

Air pollution is a global issue that affects everyone, regardless of their location or socioeconomic status. It is caused by various human activities and natural processes, and its impact on human health and the environment is well-documented.

According to the World Health Organization (WHO), about 99% of the global population breathes air that exceeds the recommended guideline limits for pollutants. This means that almost everyone is exposed to harmful levels of pollutants, such as particulate matter, carbon monoxide, ozone, nitrogen dioxide, and sulfur dioxide. These pollutants come from household combustion devices, motor vehicles, industrial facilities, and forest fires. They can cause a range of health issues, from respiratory problems to more serious conditions like lung cancer and cardiovascular disease.

People with underlying health issues, such as heart or respiratory problems, are especially vulnerable to the effects of air pollution. For example, prolonged exposure to high levels of pollutants can aggravate existing illnesses and increase the risk of stroke and cancer. Even in otherwise healthy individuals, air pollution can cause minor symptoms like wheezing, coughing, and eye and nose irritation.

Children are also particularly vulnerable to the effects of air pollution due to their smaller size and developing bodies. Globally, 93% of children breathe air with higher concentrations of pollutants than what is considered safe by the WHO. As a result, 600,000 children die prematurely each year due to air pollution, and those who survive can experience cognitive and motor impairments. Household air pollution is especially harmful to children, as they are more affected by ground-level pollution from exhaust fumes.

Air pollution also intersects with social justice and inequality, disproportionately impacting low-income communities and contributing to global health inequalities. Clean cooking and heating fuels and technologies may be unaffordable for low-income families, forcing them to rely on polluting alternatives. Additionally, people living in low- and middle-income countries suffer from higher exposures to air pollution and experience higher rates of adverse health outcomes as a result.

Air pollution is a global public health emergency, causing millions of premature deaths annually

Air pollution is a pressing issue that affects people worldwide, regardless of their location or socioeconomic status. It is a significant public health concern, causing approximately seven million premature deaths annually, according to the World Health Organization (WHO). This figure represents a staggering 800 deaths every hour or 13 deaths every minute. It is worth noting that air pollution is not limited to outdoor environments; indoor air pollution, caused by sources such as household combustion devices, also poses a significant threat to human health.

The sources of air pollution are diverse and context-specific. Outdoor pollution arises from various activities, including residential energy use for cooking and heating, vehicles, power generation, agriculture, waste incineration, and industrial processes. On the other hand, indoor air pollution is influenced by factors such as cooking and heating systems, with solid fuels and kerosene being common sources of harmful emissions.

The health impacts of air pollution are extensive and affect people of all ages. In healthy individuals, air pollution can cause minor symptoms such as wheezing, coughing, and irritation of the eyes and nose. However, for people with pre-existing health conditions, particularly heart problems and respiratory diseases, air pollution can aggravate their illnesses significantly. Prolonged exposure to polluted air, especially at high levels, has been linked to severe health conditions, including stroke, lung cancer, and other types of cancer. Additionally, air pollution has been associated with cardiovascular disease, diabetes mellitus, obesity, and reproductive, neurological, and immune system disorders.

Children are especially vulnerable to the detrimental effects of air pollution. Globally, 93% of children breathe air that exceeds the WHO's safe limits for pollutant concentrations. As a result, approximately 600,000 children die prematurely each year due to air pollution. Exposure to polluted air during pregnancy has also been linked to adverse birth outcomes, with research indicating that reducing PM2.5 exposure could lead to a decrease in low-birth weight and pre-term births worldwide.

Air pollution also intersects with social justice and inequality, disproportionately impacting underprivileged communities. Low-income families often rely on cheaper, polluting fuels and technologies for cooking and heating, leading to higher exposure to harmful pollutants. Additionally, people living in low- and middle-income countries bear the brunt of air pollution, as they experience the highest exposures to pollutants.

In conclusion, air pollution is a critical global public health emergency that demands immediate attention and action. The staggering number of premature deaths and the far-reaching health consequences underscore the urgency of implementing effective measures to mitigate air pollution. By transitioning to cleaner fuels, adopting sustainable practices, and supporting policies that prioritize air quality, we can collectively address this crisis and improve the health and well-being of people worldwide.

Household air pollution is especially harmful to women and children

Air pollution is a significant health concern for everyone, but women and children are especially vulnerable to its harmful effects, particularly in low- and middle-income countries. According to the World Health Organization (WHO), indoor and outdoor air pollution is responsible for nearly seven million deaths worldwide each year, with household air pollution accounting for an estimated 3.2 million of those deaths in 2020.

Household air pollution is caused by the use of inefficient and polluting fuels and technologies, such as open fires, kerosene stoves, and biomass fuels like wood, animal dung, and coal. These sources release harmful pollutants, including particulate matter, carbon monoxide, ozone, nitrogen dioxide, and sulfur dioxide. In poorly ventilated homes, indoor smoke can reach dangerously high levels, with fine particle concentrations up to 100 times higher than acceptable limits.

Women and children are disproportionately affected by household air pollution due to their traditional household roles. They are typically responsible for household chores such as cooking and collecting firewood, which exposes them to harmful smoke and pollutants for extended periods. The use of inefficient devices and the time-consuming process of gathering and preparing fuel further increase their exposure. As a result, women and children bear the greatest health burden, with higher risks of developing non-communicable diseases and respiratory infections.

The ingestion of kerosene is a leading cause of childhood poisonings, and the use of polluting fuels is linked to severe burns and injuries, particularly in low- and middle-income countries. Additionally, gathering fuel increases the risk of musculoskeletal injuries and exposes women and children to potential violence and injury in unsafe environments. The time spent on fuel-related tasks also limits their time for education and other productive activities.

Household air pollution contributes to a range of adverse health outcomes, including acute lower respiratory infections, chronic obstructive pulmonary disease (COPD), lung cancer, stroke, and heart disease. It is a significant risk factor for premature mortality, especially among vulnerable populations. Therefore, addressing household air pollution through interventions such as improved ventilation, the adoption of cleaner fuels and technologies, and the implementation of health-sector initiatives, is crucial to reducing the disproportionate impact on women and children's health.

Air pollution is closely linked to climate change, with similar mitigation strategies

Air pollution is a major concern for human health and the planet. According to the World Health Organization (WHO), nearly seven million deaths occur annually due to indoor and outdoor air pollution. The primary sources of outdoor pollution include residential energy use, vehicles, power generation, agriculture, waste incineration, and industry. Fine particles, carbon monoxide, ozone, nitrogen dioxide, and sulfur dioxide are among the pollutants of significant concern.

Climate change and air pollution are closely intertwined issues. Many drivers of air pollution, such as the combustion of fossil fuels, are also sources of greenhouse gas emissions. Addressing these sources of pollution can simultaneously mitigate climate change and improve air quality. For instance, transitioning to cleaner fuels and industrial processes, such as renewable energy sources like wind and solar power, can reduce air pollution while curbing global warming and its associated health impacts.

The World Bank has recognized the connection between air pollution and climate change, investing approximately $52 billion in pollution reduction efforts over two decades. One successful project in China's Hebei region, the country's largest contributor to air pollution, achieved a reduction of almost 40% in PM2.5 concentration between 2013 and 2017. This was accomplished through stringent industrial emission standards, the adoption of electric buses, the replacement of coal stoves with gas stoves, and improved fertilizer efficiency in agriculture.

To effectively tackle air pollution and climate change, a multi-faceted approach is necessary. This includes focusing on cities, investing in cross-sector energy efficiency, promoting low-carbon technologies, and fostering inclusive governance. Cities play a critical role in driving climate action and improving air quality, as they can implement policies that promote sustainable land use, cleaner household energy, energy-efficient housing, and better waste management practices.

Additionally, individuals can make a difference by making conscious choices about transportation, such as opting for walking, biking, or using public transportation whenever possible. Supporting leaders who advocate for clean air, water, and responsible climate change policies is also crucial. By addressing air pollution and climate change together, we can improve public health, strengthen economies, and build a more sustainable future.

Air pollution affects businesses, from traffic changes to manufacturing plant shutdowns

Air pollution is a pressing issue that affects everyone, from individuals to entire industries. While it poses significant health risks to people, it also has a substantial impact on businesses, influencing traffic changes and even leading to manufacturing plant shutdowns.

Traffic Changes and Business Operations

The relationship between traffic and air quality is intricate, especially in urban areas. Traffic-related air pollution (TRAP) is a significant concern, primarily due to vehicle emissions, evaporative emissions, and non-combustion emissions such as road dust and tire wear. This type of pollution is considered the leading cause of poor air quality in cities, affecting the environment and contributing to climate change. As a result, governments, city planners, and transport providers are increasingly focused on promoting sustainable transport patterns. The concept of "smart" or "green cities" has emerged as a potential solution, emphasizing improved traffic management, environmentally friendly transport options, infrastructure upgrades, and the adoption of newer technologies. These changes can have both positive and negative impacts on businesses. For instance, businesses may benefit from reduced congestion and improved sustainability, but they may also need to adapt to changing transportation methods and infrastructure upgrades.

Manufacturing Plant Shutdowns

Industrial pollution, including emissions from manufacturing plants, significantly contributes to air pollution. This type of pollution arises from various industrial activities, such as manufacturing, processing, and extracting raw materials, resulting in harmful waste products and emissions. Inadequate emission control regulations, poor enforcement of environmental standards, and the use of older, less efficient technologies contribute to the problem. Petrochemical plants, refineries, and steel mills emit several airborne pollutants, including PM2.5, sulfur dioxide, nitrogen oxides, volatile organic compounds (VOCs), and hazardous air pollutants. These emissions have severe health and environmental consequences, and in some cases, they may lead to manufacturing plant shutdowns or stricter regulations to control emissions.

Business Performance and Sustainability

Air pollution has a direct impact on business performance and sustainability. Poor air quality leads to reduced employee productivity, increased absences, and higher rates of premature deaths, resulting in significant economic losses. For example, in 2019, air pollution cost India's economy $95 billion due to these factors. Additionally, cities with severe air pollution may struggle to attract talent, as employees may view these locations as less desirable places to work. Businesses can play a crucial role in mitigating air pollution by adopting sustainable practices and reducing their carbon footprint. Initiatives like the Alliance for Clean Air, which includes companies such as Google, Siemens, Ikea, and Maersk, aim to tackle air pollution and improve sustainability. By addressing air pollution, businesses can enhance their ESG (Environmental, Social, and Governance) performance, consumer loyalty, brand value, and talent attraction and retention.

Regulations and Reporting

With growing concerns over air pollution, businesses are facing impending regulation on emissions, such as the European Commission's Corporate Sustainability Reporting Directive (CSRD). This directive includes the adoption of sustainability reporting standards, requiring companies to disclose air pollutants. Such regulations will likely become more common, and businesses that fail to address their air pollution contributions may face reputational and legal consequences. Therefore, businesses have a strong incentive to take proactive measures to reduce their environmental impact and contribute to cleaner air.
