Climate and Environmental Policy in Potsdam: March 2026 in Focus

Traffic Planning and Environmental Friendliness in the Spotlight

March 2026 in Potsdam was marked by an intensive discussion of the future of the city's traffic planning. The Committee for Climate, Environment, and Mobility decided to initiate several pilot projects to further develop the city's climate and traffic concept. Particularly noteworthy is the new planning for the middle section of Rudolf-Breitscheid-Straße. The idea of closing certain sections to motor vehicle traffic, combined with the creation of safe bicycle lanes and barrier-free tram stops, signals a clear trend away from motorized individual transport toward more environmentally friendly mobility options.

The current traffic load in Rudolf-Breitscheid-Straße amounts to approximately 5,600 to 6,300 vehicles per day. A closure would redirect car traffic, which could in turn expand to other streets such as Karl-Liebknecht-Straße or Großbeerenstraße. Nevertheless, examining such measures is a decisive step toward sustainable traffic policy.

Noise Protection and Social Justice

Another central topic was the improvement of noise protection in Alt Nowawes. The committee recommended the installation of motivational display boards as proposed in the 2024 Noise Action Plan. The aim is to remind drivers of the speed limit, especially during night and morning hours, to reduce noise pollution for residents. In addition, a noise measurement was commissioned to ensure that the load remains below legal guideline values.

The discussion on noise protection is not only an environmental issue but also a matter of quality of life and social justice. In Alt Nowawes, a district with a high proportion of residential areas, noise pollution is particularly noticeable due to the compact urban structure. The measures are therefore intended to take both ecological and social aspects into account.

Socio-Ecological Water Tariff as a Pilot Project

Another significant topic was the evaluation of a socio-ecological water tariff, inspired by the model of the French city of Dunkirk. The concept provides for a progressive, three-tiered tariff: a low tariff for basic needs, a higher tariff for useful additional consumption, and an even higher tariff for comfort consumption. Low-income households would receive automatic discounts.

Potsdam already has one of the highest water tariffs in the country, and further increases due to rising costs for water and sewage could particularly burden low-income households. The Dunkirk model offers an alternative that combines social and ecological goals: a fair distribution of costs, incentives for water conservation, and climate protection. The city administration will submit a report on implementation possibilities and legal conditions by September 2026.

30 km/h Zones as a Climate Protection Measure

The expansion of 30 km/h zones is another key element of Potsdam's climate and traffic policy. The committee decided to continue the evaluation of the installation of 30 km/h signs in residential areas of the district Marquardt. In addition, a general status report on "30 km/h in the city area" will be presented, summarizing past experiences.

Creating 30 km/h zones not only contributes to noise protection and safety but also to the reduction of CO₂ emissions. Slower speeds lead to lower fuel consumption and thus fewer greenhouse gases. In combination with other measures such as bicycle traffic lights and environmentally friendly mobility options, this is a central component of the city's climate protection strategy.

Conclusion: Toward Climate Neutrality by 2035

March 2026 marks an important milestone in Potsdam's climate and environmental policy. The measures decided—ranging from traffic re-planning and the socio-ecological water tariff to the transition to fossil-free energy—show that the city is on a clear path toward climate neutrality by 2035. The challenge now lies in concrete implementation, long-term financing, and public acceptance. However, with the current developments, Potsdam has a clear roadmap for the coming years.
