Zurich Airport has faced operational and environmental scrutiny amid rising activity levels. In July 2026, Eurocontrol data indicated that the airport recorded only 46% on-time departures, the lowest punctuality rate among the 20 busiest European hubs.

By August 2026, the region faced simultaneous environmental pressures, including record heatwaves and low water levels in Lake Zurich. Despite these local climate challenges, flight activity at the airport reached record levels. Data shows that the average Zurich resident flew 10,500 kilometers in 2024, resulting in approximately 3.2 tons of CO2 emissions—a figure described as 1.5 times the total CO2 output of the city’s combined heating, transport, and electricity usage.
