Woerden's air quality reflects the flat Dutch Randstad Green Heart position between Utrecht and The Hague, with vehicle traffic on the A12 motorway and surrounding suburban and dairy farming operations contributing local sources. North Sea westerlies carry relatively clean Atlantic air, while the flat Dutch polder landscape allows reasonable dispersal and the surrounding greenhouse and dairy agriculture contributes localised ammonia and NOₓ, generally maintaining Woerden at moderate Dutch Randstad urban air quality levels throughout the year.
