Copenhagen's air quality is generally good, benefiting from consistent Baltic and North Sea westerlies that provide reliable maritime ventilation across the low-lying Danish capital. Traffic on the ring roads contributes the primary local emissions, while the flat Danish landscape and Copenhagen's strong cycling culture limit vehicle emissions compared to comparable European capitals.
