Record number of complaints filed against Copenhagen Airport over noise and air pollution

A record 38,479 complaints about noise and air pollution were lodged against Copenhagen Airport last year, according to new figures obtained by Danish broadcaster DR from the Environmental Protection Agency.

The total marks a more than sixfold increase compared to just two years prior, with 939 individuals submitting complaints in 2023. Many residents near the airport report health concerns linked to ultrafine particle emissions, particularly when aircraft operate on the ground.

Louise Raaschou Petersen, a resident living roughly two kilometres from the airport and spokesperson for the citizen group Borgere mod Lufthavnsforurening (Citizens Against Airport Pollution), described the impact on daily life.

“We skip runs and keep our windows closed,” she said. “We’re worried we’re exposed to something harmful to our health. It gives us a sinking feeling in our stomachs.”

Health studies underway
The Danish Cancer Society is currently investigating whether residents over 40 who have lived near the airport for at least 20 years show increased respiratory symptoms. Results are expected within a year. Separately, a three-year research project will examine particle pollution levels and their effects on airport employees.

Political pressure for stricter regulations
Several political parties are pushing for tighter controls. Leila Stockmarr, a parliamentary candidate for the Red-Green Alliance (Enhedslisten), called for immediate measures, including banning night flights, relocating cargo operations, and setting emission reduction targets.

“Freight transport shouldn’t be concentrated in a city-centre airport,” Stockmarr said. “We need transparency on particle measurements and stricter rules on where planes taxi and idle.”

Justice Minister Peter Hummelgaard of the Social Democrats also backed stricter oversight, advocating for low-aromatic fuels to cut harmful emissions and greener flight operations.

Airport claims progress on emissions
Copenhagen Airport acknowledged the issues but stated that pollution levels are improving. Sustainability director Maria Skotte cited a 28% reduction in ultrafine particles between 2019 and 2025, attributed to newer aircraft, faster auxiliary engine shutdowns, and collaboration with Amsterdam’s Schiphol Airport on air filtration technology.

Last year, the airport handled a record 32.4 million passengers, surpassing the previous high of 30.3 million in 2018.
