Introduction

A study commissioned by the campaign group Transport & Environment (T&E) reveals that the health of over 50 million people residing within a 20-kilometre radius of Europe’s busiest airports is being negatively impacted by high levels of ultrafine air pollution emitted by jet engines.

The Impact of Ultrafine Particles

Studies suggest that ultrafine particles can increase the risk of various health conditions, including respiratory diseases, cardiovascular diseases, neurological conditions, diabetes, and pregnancy issues. The research conducted by consultancy CE Delft in the Netherlands aimed to estimate the Europe-wide impact of ultrafine pollution based on these studies.

Uncertainties and Lack of Monitoring

Ultrafine pollution is a relatively understudied aspect of air pollution, leading to significant uncertainties. There is limited research in this area, and the evidence is often inconclusive. Monitoring of ultrafine particle levels is also lacking, with only local studies conducted around individual airports.

Estimating the Europe-wide Impact

The researchers estimated the levels of ultrafine pollution around Europe’s 32 busiest airports by extrapolating data from studies conducted at individual airports. They assumed a linear relationship between ultrafine pollution and the number of flights, without considering wind patterns. Based on studies examining the health impacts of ultrafine particles, the team estimated that the pollution near these airports has resulted in additional cases of high blood pressure, diabetes, and dementia.

Limitations and the Need for Further Research

The estimates provided by the study are considered a first-order approximation and should be further refined through epidemiological research. The study’s scope is limited to 32 airports and individuals living within a 20-kilometre radius, excluding airport workers. More comprehensive research is necessary to fully understand the risks associated with ultrafine particles from aviation.

Potential Solutions

To reduce ultrafine pollution levels, several measures can be implemented. Modifying jet fuels, such as reducing the sulphur content, can help decrease ultrafine particle emissions. The use of sustainable aviation fuels (SAF) also results in lower ultrafine pollution. However, scaling up SAF production to have a significant impact may take time. Limiting airport expansion, reducing flight numbers, and promoting alternative forms of transportation can also contribute to reducing both ultrafine pollution and the climate impacts of flying.
