Air pollution is a critical issue that affects billions of people worldwide. According to the World Health Organization (WHO), an estimated 9 out of 10 people, or around 3 billion individuals, breathe air with high levels of pollutants. This issue is more prevalent in low and middle-income countries, where indoor pollution rates are high due to the use of solid fuels for cooking, and outdoor pollution increases during industrialization. The health impacts of air pollution are significant, contributing to an estimated 7 million deaths annually from diseases such as stroke, heart disease, and lung cancer. The situation is worsening due to the vicious cycle of climate breakdown and inequality, with those in poverty, women and girls, Indigenous communities, and Global South countries bearing the brunt of climate impacts. However, there is hope, as some data suggests that we may be approaching peak pollution deaths and that death rates from air pollution are falling even in highly polluted countries. Addressing the excessive emissions of the super-rich and investing in public services and renewable energy sources are crucial steps in tackling this global challenge.

What You'll Learn
Air pollution kills 7 million people annually
Air pollution is a combination of outdoor and indoor particulate matter and ozone. It is a major health and environmental issue worldwide, with indoor pollution being a particular problem in low-income countries due to the reliance on solid fuels for cooking. Outdoor air pollution tends to increase as countries industrialize and shift from low to middle incomes.
According to the World Health Organization (WHO), air pollution kills 7 million people every year. The Institute for Health Metrics and Evaluation (IHME) gives a similar number of 6.7 million. Some scientists think this number could be even bigger, with some of the most recent and widely cited studies estimating that at least 9 million people die every year from air pollution.
Air pollution increases the risk of respiratory disease, stroke, cardiovascular disease, lung cancer, heart disease, diabetes, and chronic obstructive pulmonary disease (COPD). It is responsible for more deaths than smoking, which kills around 8 million people annually, and road accidents, which kill 1.3 million. It also causes long-term health problems such as asthma and reduces children's cognitive development.
While air pollution is falling in many countries, it is still one of the world's biggest killers. It is caused by the burning of fossil fuels for power and transport, the chemicals and mining industries, the open burning of waste, the burning of forests and fields, and the use of dirty indoor cooking and heating fuels.
To improve air quality and reduce the number of deaths from air pollution, individuals can make informed decisions about the levels of air pollution in their area and choose green purchases. Businesses and governments can also implement policies and investments that support sustainable land use, cleaner household energy and transport, energy-efficient housing, and better municipal waste management.

9/10 people breathe polluted air
Air pollution is a serious issue that affects people all over the world. According to the World Health Organization (WHO), 9 out of 10 people worldwide breathe air containing high levels of pollutants. This means that approximately 7 million people die prematurely each year due to the combined effects of outdoor and household air pollution. The problem is especially severe in low- and middle-income countries, where exposure to unhealthy air is significantly higher than the global average.
Outdoor air pollution is caused by a variety of sources, including residential energy use for cooking and heating, vehicles, power generation, agriculture/waste incineration, and industry. In recent years, there has been a growing awareness of the impact of fossil fuel combustion on both air quality and the climate. Fine particulate matter, such as PM2.5, can penetrate deep into the lungs and even enter the bloodstream, causing cardiovascular, cerebrovascular, and respiratory issues. These particles have been linked to an increased risk of heart disease, stroke, lung disease, cancer, and pneumonia.
Household air pollution is also a significant contributor to the overall problem. It is estimated that around 2.4 billion people are exposed to dangerous levels of indoor air pollution, primarily from the use of polluting open fires or simple stoves fueled by kerosene, biomass (wood, animal dung, and crop waste), and coal. The impact of indoor air pollution is felt most heavily in low-income countries, where solid fuels are commonly used for cooking.
Despite these grim statistics, there is some progress being made. More than 6,000 cities in 117 countries are now monitoring air quality, and countries are working together to implement solutions for sustainable transport, renewable energy production, and waste management. Additionally, organizations like WHO and the UN are actively raising awareness, providing guidance, and promoting interventions to reduce air pollution levels and mitigate risks associated with exposure.

Fossil fuels and household energy are major sources
Fossil fuels are a major source of pollution. They are formed from the decomposition of carbon-based organisms that died and were buried millions of years ago. Coal, oil, and gas are the three types of fossil fuels, and they currently supply around 80% of the world's energy. When burned, fossil fuels release nitrogen oxides into the atmosphere, contributing to smog and acid rain formation. They also emit ammonia, which, in excess, is toxic to aquatic life.
The combustion of fossil fuels is a significant contributor to greenhouse gas emissions and air pollution. Oil releases a large amount of carbon when burned, accounting for about a third of the world's total carbon emissions. Similarly, natural gas, often promoted as a cleaner alternative to coal and oil, still accounts for a fifth of the world's carbon emissions. Coal is the most carbon-intensive fossil fuel, responsible for over 0.3 degrees Celsius of the 1-degree increase in global average temperatures.
Household energy use is another major source of pollution. Energy poverty and indoor air pollution have long been a problem, with approximately 2.4 billion people exposed to dangerous levels of household air pollution. This is often due to the use of polluting open fires or simple stoves for cooking, fueled by kerosene, biomass (wood, animal dung, crop waste), and coal. Solid fuels, in particular, are a significant contributor to indoor pollution in low-income countries.
Outdoor air pollution is also a concern, especially in industrializing countries. Residential energy for cooking and heating, vehicles, power generation, agriculture, waste incineration, and industry are all major sources of outdoor pollution. Policies and investments that support sustainable land use, cleaner household energy, and energy-efficient housing can help reduce ambient air pollution.
The impact of air pollution on health and the environment is significant. It has been linked to various diseases and causes approximately seven million deaths worldwide each year. Air pollution also affects the quality of life for many people, contributing to respiratory and heart issues, as well as other health problems.

Pollution levels vary across countries
Air pollution is a critical health and environmental issue worldwide, but its severity varies significantly across different countries and regions. It is one of the leading risk factors for death, contributing to an estimated seven million deaths annually worldwide. The impact of air pollution extends beyond premature mortality, also affecting the quality of life for those exposed to it.
The sources of air pollution are diverse and context-specific, with outdoor pollution stemming from residential energy use, vehicles, power generation, agriculture, waste incineration, and industrial activity. While indoor air pollution is also a significant concern, especially in low-income countries, where the use of solid fuels for cooking is prevalent.
The burden of air pollution tends to be disproportionately higher in low and middle-income countries. This disparity arises from a combination of factors. Firstly, indoor pollution rates are typically elevated in low-income countries due to their reliance on solid fuels for cooking, which contributes to hazardous indoor air quality. Secondly, as countries industrialize and transition from low to middle-income statuses, their outdoor air pollution levels tend to increase. This correlation underscores the intricate link between industrialization and air pollution.
However, it is important to acknowledge that air pollution is not solely an issue in developing nations. Even within high-income countries, certain areas consistently exhibit higher pollution levels. For instance, in the United States, approximately 140 million people resided in counties with pollution levels exceeding the primary NAAQS standards in 2023. Nonetheless, the overall trend in the US has been positive, with a 74% reduction in air toxic emissions between 1990 and 2017, driven by regulatory measures and technological advancements.
To address air pollution effectively, a multifaceted approach is necessary, encompassing policies and investments that promote sustainable land use, cleaner household energy, improved waste management, and energy-efficient housing and transportation. By tackling these issues, countries can significantly reduce ambient air pollution and mitigate its adverse health and environmental impacts.

The poorest are most affected by pollution
Air pollution is a significant health and environmental issue worldwide, causing approximately seven million deaths annually. While pollution affects everyone, the poorest are disproportionately impacted by its adverse effects. This disparity is evident across various regions, from Lagos to London, where low-income communities bear the brunt of the consequences.
One of the primary reasons the poorest suffer the most from pollution is their proximity to pollution sources. Marginalised, low-income communities are often situated near industrial plants, highways, and rubbish dumps, exposing them to higher levels of harmful pollutants. Additionally, those in poverty tend to be priced out of cleaner, leafy suburbs with better air quality. This inequality in exposure contributes to a higher risk of health issues among the poor.
Indoor air pollution also disproportionately affects the poorest. In developing countries, indoor air quality is often poor due to the reliance on solid fuels, such as wood, charcoal, kerosene, or biomass (including wood, animal dung, and crop waste) for cooking, heating, or lighting. Approximately 2.4 billion people are exposed to dangerous levels of household air pollution from using polluting open fires or simple stoves fuelled by these solid fuels. The inability to afford cleaner fuels or alternative technologies exacerbates the problem, impacting the health and well-being of vulnerable populations.
Socioeconomic status also plays a significant role in the impact of air pollution. Multiple studies have found a link between low socioeconomic status and an increased risk of premature death from fine particle pollution. This disparity is evident in communities with higher African American populations, lower home values, and lower median incomes. Additionally, poverty-stricken areas often offer poorer job opportunities, have dirtier workplaces, and provide less access to healthcare, further increasing the vulnerability of residents to the detrimental effects of pollution.
Furthermore, the poorest countries, which account for nearly 60% of the world's population, are more vulnerable to the impacts of climate change driven by pollution. Climate change has disrupted growing seasons, destroyed crops, and killed livestock, severely affecting the livelihoods of the rural poor, who heavily depend on natural resources. The lack of insurance coverage, which is common in low-income countries, further hinders their ability to recover from climate-related disasters.
Overall, while pollution is a global issue, it is the poorest who are most vulnerable to its detrimental health, environmental, and economic consequences. Addressing this inequality requires interventions that improve access to clean fuels, promote sustainable practices, and reduce exposure to harmful pollutants among vulnerable communities.
