Clean air values improved thanks to successful implementation of the city of Offenbach am Main's overall strategy

40 micrograms of nitrogen oxides is the maximum value that was set in 2010 on the basis of an EU directive from 1999. However, because air knows no city limits and selective individual measures do not reduce the levels of nitrogen oxides (NOx) in the air permanently and, above all, quickly enough, the "Green City Master Plan" was developed together with the city of Frankfurt.

On the basis of this plan, the city compiled an inventory and analysis of mobility behavior and then developed an overall strategy with a comprehensive catalog of measures.

The current clean air plan of the state of Hesse, which has been legally binding since October 2020, adopted these measures.

The city favors traffic reduction through traffic-dependent digital traffic light control, the expansion of cycling infrastructure, the strengthening of local public transport, the electrification of the bus fleet and a 40 km/h speed limit. Due to the already falling values, the city has decided to forego a ban on trucks driving through the city and the installation of gateway traffic lights, for example on Bieberer Berg.

The introduction of a 40 km/h speed limit on three particularly congested stretches of road, such as Mainstraße Initially, a permanent speed limit of 40 km/h is planned for three sections from March 2021. This applies to Mainstrasse (around 1.1 kilometers from Arthur-Zitscherstrasse to Kaiserstrasse), Waldstrasse (around 130 meters from Geleitsstrasse to Bleichstrasse) and Kaiserstrasse (a good 150 meters from Geleitsstrasse to Große Marktstrasse).

Other measures relate to the strengthening of cycling and local public transport. The development of Offenbach into a cycling city is being driven forward with great enthusiasm. For example, one-way streets have been opened to cyclists, the infrastructure has been improved and an e-bike rental system has been established. In addition, campaigns such as the STADTRADELN (CITY CYCLING) climate protection initiative have inspired many people to take up this form of transportation: In the last CITY CYCLING campaign in 2020, 705 cyclists in 40 teams covered the impressive distance of 172,955 kilometers.

E-mobility is also an important building block, with the expansion of car and bike sharing services and the development of additional charging stations being driven forward. This also includes the electrification of municipal and commercial fleets, with all company vehicles at the city administration gradually going electric.

The buses operated by Offenbacher Verkehrsbetriebe (OVB) are now also silent and low-emission, with the first 7 buses in operation and more to follow this year. The planners hope that the use of real-time displays at the bus stops will make the service even more attractive and allow passengers to plan their journey in the best possible way. Anyone who still needs a car for part of the journey can leave it at the planned park and ride parking lots at the Nassen Dreieck or at the stadium.
