Low-emission zones in Hesse

Hesse has six active low-emission zones, all of them green: Frankfurt am Main, Darmstadt, Offenbach am Main, Wiesbaden, Marburg and Limburg an der Lahn. The state is responsible for the clean-air plans, specifically the Environment Ministry in Wiesbaden; the southern zones are based on sub-plans of the clean-air plan for the Rhine-Main conurbation, while Marburg and Limburg rest on the plan for central and northern Hesse. Frankfurt is the oldest Hessian zone, set up in 2008 and green since 2012. Wiesbaden followed in 2013, together with Mainz, whose part has since been lifted. Offenbach and Darmstadt joined in 2015, Marburg on 1 April 2016 and Limburg in early 2018. For Limburg the city and the state give different dates: the city says 31 January 2018, the state 1 January 2018; the German Environment Agency follows the city. In Marburg, according to the state, federal road B 3 is excluded from the zone. Darmstadt has also had bans on older diesels on two streets since 2019. The city pages on this were unreachable during our check, and the state only mentions the zone; whether the route bans still apply in 2026 is therefore not confirmed. No zone in Hesse has been lifted so far.
