The amount of pollution generated by people varies across countries, generations, and income groups. According to the World Health Organization (WHO), 99% of people breathe air that exceeds the guideline limits for pollutants, with those in low- and middle-income countries suffering the highest exposures. The richest 1% of the world's population, approximately 77 million people, produce a disproportionate amount of pollution. Their carbon-intensive lifestyles and investments in polluting industries contribute significantly to global warming. Oxfam estimates that the richest 1% emitted as much carbon pollution in 2019 as the poorest two-thirds of humanity (around five billion people). This inequality in emissions has severe health and environmental consequences, with nearly seven million deaths attributed to indoor and outdoor air pollution annually.

The richest 1% produce more carbon pollution than the poorest two-thirds of humanity
Air pollution is the contamination of the indoor or outdoor environment by any chemical, physical, or biological agent that modifies the natural characteristics of the atmosphere. According to the World Health Organization (WHO), indoor and outdoor air pollution causes nearly seven million deaths worldwide each year. WHO data shows that 99% of the global population breathes air that exceeds the guideline limits for pollutants, with those in low- and middle-income countries suffering the highest exposures.
The richest 1% of the world's population, comprising 77 million people, produced more carbon pollution in 2019 than the poorest two-thirds of humanity, or five billion people. This stark disparity is highlighted in a report by Oxfam, titled "Climate Equality: A Planet for the 99%." The report reveals that the richest 1% were responsible for 16% of global consumption emissions in 2019, exceeding emissions from all car and road transport.
The excessive emissions of the super-rich are driven by their carbon-intensive lifestyles and investments in polluting industries, such as fossil fuels. Their lavish consumption includes the use of private jets and yachts, contributing to significantly larger carbon footprints than the average person. Additionally, the influence of the super-rich over media, politics, and policymakers allows them to protect their financial interests and hinder progress toward renewable energy.
The consequences of this inequality in carbon emissions are severe. The emissions of the richest 1% will lead to approximately 1.3 million heat-related deaths between 2020 and 2030. Moreover, the excessive emissions contribute to global warming, threatening the survival of millions and exacerbating climate change. To address this crisis, Oxfam proposes taxing the incomes of the richest 1%, which could generate funds to transition to renewable energy and reduce emissions.

Household air pollution: open fires or simple stoves for cooking
According to the World Health Organization (WHO), around 2.4 billion people are exposed to dangerous levels of household air pollution. This is caused by the use of polluting open fires or simple stoves for cooking, fuelled by kerosene, biomass (wood, animal dung, and crop waste), and coal. The indoor air pollution resulting from these practices can be up to 20 times worse than the WHO's air quality guidelines.
Burning solid fuels, such as wood, charcoal, coal, and kerosene, releases dangerous particulate matter, carbon monoxide, and other toxic pollutants. These pollutants are associated with various diseases, including childhood pneumonia, chronic obstructive pulmonary disease, acute respiratory infections, heart disease, stroke, and lung cancer. The ingestion of kerosene is the leading cause of childhood poisonings, and it also contributes to severe burns and injuries, especially in low- and middle-income countries.
The use of polluting fuels and technologies disproportionately affects women and children, who are typically responsible for household chores such as cooking and collecting firewood. They are exposed to harmful smoke and bear a greater health burden, including an increased risk of musculoskeletal injuries. Additionally, pregnant women exposed to these pollutants have infants at risk for stillbirth, low birth weight, and decreased lung function.
To address household air pollution, it is essential to expand the use of clean fuels and technologies. These include solar, electricity, biogas, liquefied petroleum gas (LPG), natural gas, alcohol fuels, and improved biomass stoves that meet emission targets. Clean cooking programs that promote these alternatives can receive carbon credits, as they significantly reduce emissions and improve health and environmental outcomes.
While the richest 1% of the world's population produces a significant amount of carbon pollution, the use of polluting open fires and simple stoves for cooking by billions of people also contributes to overall air pollution levels and has severe health consequences. Therefore, addressing household air pollution through the adoption of cleaner alternatives is crucial for protecting public health and the environment.

Outdoor air pollution: vehicles, power generation, industry
Outdoor air pollution is a major environmental health problem affecting everyone in low-, middle-, and high-income countries. According to the World Health Organization (WHO), nearly seven million premature deaths worldwide each year are caused by indoor and outdoor air pollution. Outdoor air pollution alone caused 4.2 million premature deaths in 2019. These deaths are due to exposure to fine particulate matter, which causes cardiovascular and respiratory disease, and cancer.
One of the major sources of outdoor air pollution is vehicles. Vehicle emissions include greenhouse gases (GHGs) such as carbon dioxide and methane, which contribute to smog, haze, and health problems. Conventional vehicles with internal combustion engines (ICE) produce direct emissions through the tailpipe, as well as through evaporation from the vehicle's fuel system and during fueling. Gasoline, for example, produces emissions during extraction, refinement, distribution to stations, and burning in vehicles. While all-electric vehicles and plug-in hybrid electric vehicles (PHEVs) have zero tailpipe emissions, electricity production for these vehicles, such as through power plants, may still generate emissions. In areas with higher-emissions electricity, electric vehicles may not demonstrate as strong a life cycle emissions benefit.
Another significant contributor to outdoor air pollution is power generation. Nearly all types of electric power plants affect the environment, but some have larger effects than others. In the United States, about 62% of total electricity generation in 2022 was produced from fossil fuels, which release harmful substances during combustion. These substances include carbon dioxide (CO2), a greenhouse gas; sulfur dioxide (SO2), which causes acid rain and worsens respiratory illnesses; nitrogen oxides (NOx), which contribute to ground-level ozone and irritate and damage lungs; and fine particulate matter (PM), which is linked to asthma, chronic bronchitis, emphysema, and lung cancer. Additionally, power plants produce ash, which contains hazardous materials captured by pollution control devices. The improper storage or disposal of ash, such as through landfills, can lead to groundwater pollution and extensive environmental damage.
Industrial facilities are also significant sources of outdoor air pollution. Industrial activities, including combustion processes, release various pollutants into the atmosphere. Nitrogen dioxide (NO2), a common pollutant from the combustion of fuels, is often released from the industrial sector. Particulate matter (PM), a proxy indicator for air pollution, includes components such as sulfates, nitrates, ammonia, sodium chloride, black carbon, mineral dust, and water. These pollutants have negative health impacts, contributing to respiratory and other diseases. Additionally, people living near industrial areas are at a much higher risk for respiratory disease, cardiovascular disease, neurological damage, cancer, and premature death.

People of colour are more likely to live in areas with poor air quality
People are responsible for generating a significant amount of pollution, with human activities leading to the release of various pollutants into the atmosphere. This includes indoor and outdoor air pollution, which has detrimental effects on both human health and the planet. According to the World Health Organization (WHO), nearly seven million premature deaths occur globally each year due to air pollution. Additionally, about 2.4 billion people are exposed to dangerous levels of household air pollution from the use of polluting cooking methods.
While pollution affects people across the globe, it is important to recognize that the burden of pollution is not shared equally. People of colour are disproportionately impacted by air pollution and are more likely to live in areas with poor air quality. This disparity is evident in the United States, where people of colour are 1.5 times more likely than white people to reside in areas with poorer air quality. This inequality is not solely based on income or socioeconomic status but is deeply rooted in historical and systemic racism.
Racist zoning policies and discriminatory lending practices, such as redlining, have played a significant role in this disparity. Redlining involved marking predominantly Black neighbourhoods as risky for real estate investments, leading to a lack of investment and the concentration of polluting industries and highways in these areas. As a result, communities of colour, especially Black communities, have been exposed to higher levels of pollution from industrial facilities, diesel emissions, and traffic pollution. This pattern is not limited to a specific region or income level but is widespread across states, urban and rural areas, and different socioeconomic groups.
Furthermore, socioeconomic status also influences the impact of air pollution. Studies have found that low socioeconomic status increases the risk of premature death from fine particle pollution. People of colour often face higher exposure to pollutants and experience greater health responses due to their social position and proximity to pollution sources. Additionally, they may have limited access to healthcare, healthy food options, and job opportunities, further exacerbating the impact of air pollution on their health and well-being.
Addressing these disparities requires recognizing the intersection of race and socioeconomic factors in exposure to air pollution. Initiatives focused on improving air quality, such as those led by the Environmental Protection Agency (EPA), aim to provide equal protection from environmental hazards and promote access to decision-making processes for all communities. By understanding the specific concerns of overburdened communities and addressing health impacts, these initiatives strive to ensure that all people can breathe clean air and enjoy an improved quality of life.

Frequently asked questions
On average, a person in the United States has a carbon footprint of 16 tons, one of the highest rates in the world. The global average is closer to 4 tons. However, this average is heavily skewed by the super-rich, with the top 1% of emitters each having carbon footprints of over 50 tons in 2021.
Individual emissions can be categorized into household consumption, personal transport, and emissions embodied in consumed goods and services. Household heat and electricity consumption are essential for all and thus remain relatively uniform across income groups. However, personal transport emissions vary significantly, with aviation-related emissions being especially unequal.
Emissions vary significantly across income groups. In 2021, the average North American emitted 11 times more energy-related carbon dioxide than the average African. The top 1% of emitters globally produced over 1,000 times more carbon dioxide than the bottom 1%.
The richest 1% of the world's population, approximately 77 million people, were responsible for 16% of global consumption emissions in 2019. This is more than all car and road transport emissions and equivalent to the emissions of the bottom 5 billion people, or the poorest two-thirds of humanity.
Governments can play a crucial role in tackling this issue by targeting the excessive emissions of the super-rich. Oxfam suggests that a 60% tax on the incomes of the richest 1% could significantly reduce emissions and raise funds for the transition to renewable energy sources.
