Types of Airport Pollution
Airports are complex ecosystems that generate various types of pollution, each with its own set of environmental and health implications. Let’s understand the basics to see the bigger picture:
- Air Pollution: Probably the first type of pollution that comes to mind when we think of airports. It comes from aircraft engine emissions, ground support equipment, and vehicular traffic around the airport. This air pollution includes the release of greenhouse gases, volatile organic compounds, nitrogen oxides, and particle matter. These pollutants also contribute to climate change statistics and pose a significant threat to our health.
- Noise Pollution: Airports generate high levels of noise due to aircraft takeoffs, landings, and ground operations. This noise can have massive effects on nearby communities, causing annoyance, sleep disturbance, and even long-term health issues like stress and cardiovascular problems.
- Water Pollution: Airport operations can lead to water pollution through runoff, accidental chemical spills, and waste disposal of hazardous substances.
- Land Pollution: Airport construction and operation can contribute to land pollution through soil contamination (aviation fuel chemicals) or waste generation.
Each of these pollution types plays a role in the total sum of airport pollution facts. You’ll find related statistics for them below.
Air Pollution & Airports — Facts & Stats
Let’s explore how the aviation industry contributes to air pollution stats.
Aviation contributes just 2.5% of the world’s total CO2 emissions.
(Source: Our World in Data)
The reason behind aviation’s CO2 emissions is that most flights are fueled by jet gasoline, which when burned converts into CO2. Aviation’s impact on global warming, including other greenhouse gases, is about 3.5%. This is lower than other industries, and we currently don’t have many options to reduce it further.
The top 1% wealthiest people produce half of the global aviation emissions.
In other words, if you’re panicking that your few vacations a year with a plane generate a huge amount of airplane CO2 emissions — don’t. The rich can afford to fly daily, and their produced emissions affect us all. You can panic about that instead. One suggestion is introducing a tax based on traveled air miles, but we’re yet to see it implemented.
Emissions from global aviation cause 16,000 premature deaths per year worldwide.

These premature deaths are due to people being exposed to harmful particles (PM2.5) and ozone from aviation. Among these deaths, 87% are linked to PM2.5, 13% to ozone, and 25% are caused by emissions during takeoff and landing. The findings indicate that approximately 5,000 premature deaths occur within 12 miles of 1,000 airports. This accounts for about 32% of all premature deaths attributed to both PM2.5 and O3 from aviation. Among these deaths near airports, 25% are in North America, 38% in Europe, 22% in Asia, and the remaining 15% in other regions.
In 2020, CO2 emissions from aviation declined by 60%.
This shows the unprecedented impact of the global pandemic on the travel industry. With widespread travel restrictions and lockdowns, air travel saw a dramatic decrease, leading to a substantial decrease in aviation carbon emissions. This reflects the delicate balance between economic activities and environmental sustainability. As the world recovers and travel resumes, it’s time to reevaluate and implement strategies that can maintain this positive trend by incorporating more sustainable practices into the aviation sector.

The US accounts for 23% of CO2 emissions, while the European Union and China account for 19% and 13%, respectively. The US contributed over 175 million metric tons of CO2 emissions. China generated over 90 million metric tons, and it’s projected to become the world’s biggest aviation market by 2050.
In 2021, Ryanair flights within the EU resulted in 4.9 million metric tons of emissions.
Unsurprisingly, this is consistently the airline that causes the most aviation pollution within the EU. While affordability has made air travel more accessible to us, this also emphasizes the need for adopting and investing in greener aviation technologies and practices. As air travel demand continues to grow, striking a balance between economic expansion and environmental responsibility is crucial.
More than 65,000 students in California are exposed to airport pollution daily during the school year.
It’s clear that schools near airports expose children to harmful emissions. There’s also a correlation between indoor and outdoor air pollution, so they’re actually exposed to the pollution throughout their time in school. These can lead to long-term health risks, especially for economically disadvantaged children.
Ultrafine particles (UFPs) from jet aircraft emissions contribute to pre-term birth among others living within 15 km of LAX.
The study involved over 145,000 mothers and found that the emissions exacerbate the issue, regardless of noise and traffic pollution. The results raise significant public health worries since exposure to UFPs near airfields is widespread and could impact heavily populated residential areas.
Just 5 hours of exposure to aviation-related UFP is linked to slight declines in lung function.

The air quality near airports is bad, and this study proves it. The effects were modest but were observed after just 5 hours of exposure among young, healthy adults. However, the study doesn’t draw conclusions about how this might affect health over a long period.
Noise Pollution & Airports
It’s clear that airports are noisy, but what impact does that noise have on our lives? Well, if you live near an airport, you have causes to worry:
Nearly 300,000 Americans live in areas near airports with significant noise pollution.
Noise pollution not only disrupts daily life but also has a range of potential health impacts, including sleep disturbances, stress, and even cardiovascular issues. These findings show the need for comprehensive urban planning that considers the balance between infrastructure development and the well-being of local residents.
People exposed to airplane noise are more likely to sleep less than seven hours a night.
While we often focus on airplane carbon emissions, we tend to forget about the noise. Noise pollution should be considered in urban environments, and its potential impact on our sleep shows the need for better planning. It not only affects personal well-being but also raises questions about the design of airport locations and flight paths, along with the implementation of noise mitigation strategies.
Students in Korea exposed to airplane noise pollution showed significantly lower reasoning and IQ scores.

The study suggests a link between chronic noise exposure from military airfields and decreased cognitive functions in Korean children. However, we need more research to see how noise might influence cognitive function and how we can mitigate these effects and prioritize healthier learning environments for children living near such high-noise areas.
Older people exposed to regular airplane noise have a 3.5% higher chance of hospitalization for cardiovascular diseases.
The results contribute to existing evidence linking aviation pollution from noise to various cardiovascular conditions, including hypertension, ischemic heart disease, and heart attacks. These findings show the far-reaching health impact of noise pollution in environments near airports or flight paths. It’s clear that measures to reduce noise exposure can play a big role in safeguarding the well-being of the elderly.
Water Pollution & Airports
Let’s explore how airports impact nearby water sources and how that contributes to growing water pollution statistics.
Water runoff from airports can carry dangerous pollutants, including benzotriazoles, heavy metals, and pesticides.
The pollutants can enter runoff waters during activities like refueling, aircraft maintenance, and cleaning. These contaminants are highly toxic and can potentially cause cancer. This issue is a significant concern for people living near airports.
Chemical spills from airports can lead to water contamination and toxicity to aquatic life.
Discharged substances like ammonia, heavy metals, and jet fuel can be detrimental to plant and fish species, which can disturb the whole ecosystem. But they can also wreak havoc in other ways. For instance, when some of these substances break down into water that could lead to oxygen depletion.
De-icing agents used at airports affect groundwater and soil quality.
This refers to commonly used de-icing agents like propylene glycol and potassium formate. They get into the soil as the snow melts, affecting plant and animal life nearby. This issue also affects the oxygen levels of the soil.
The Health Risks of Living Near an Airport
Living near an airport can expose you to a range of health risks due to noise pollution, air quality, and potential chemical exposure. Here are a few:
- Noise Effects: Airports are noisy due to takeoffs, landings, and ground operations. Prolonged exposure to this noise has been linked to sleep disturbances, stress, anxiety, and cardiovascular problems. It can also impact cognitive development in children.
- Air Quality Concerns: Airports produce harmful emissions with pollutants such as nitrogen oxides, volatile organic compounds, and particle matter into the air. Poor air quality can exacerbate respiratory conditions like asthma and increase the risk of respiratory infections.
- Chemical Exposure: You can be exposed to chemicals for aircraft maintenance, de-icing, and other operations. Some of them can have adverse health effects if not properly managed or if they enter water systems and soil.
- Psychological Effects: Constant exposure to aircraft noise and the potential safety risks associated with living near an airport can contribute to stress and anxiety.
The extent of the health risks of living near an airport can vary depending on the airport’s size, location, operations, and the surrounding environment. Still, if you have a choice, it’s best to live away from the airport. But if you don’t, you should look into ways to improve your air quality at home.
