Sittard-Geleen's air quality reflects its position as a rolling loess-hill town in Limburg, with local industry and A2 traffic together accounting for most urban emissions here. With the loess hill country of South Limburg close by supporting air movement, and the former coal-mining region turned chemical industry hub shaping the local climate, conditions generally track the wider Dutch average.
