Paderborn on the Path to Climate-Neutral Heating – Analysis of the March 2026 Meeting

Paderborn has established itself as a pioneer in municipal climate protection in recent years. In March 2026, the Committee for Environment, Climate, and Mobility decided on further steps toward a climate-neutral heating supply. With a clear roadmap until 2040 and a detailed division of the city area into heating supply zones, Paderborn is pursuing a future-proof and sustainable energy strategy.

## Heating Transition Strategy and Climate Neutrality

The heating transition strategy is the central building block of climate protection policy in Paderborn. The goal is to achieve a greenhouse gas neutral heating supply by 2040. To this end, the city has developed a roadmap that takes both technical and financial aspects into account.

Key aspects of the strategy:

• Electrification of the heating supply: Heat pumps (air, water, geothermal) are the key technologies.
• Decentralized solutions: In areas where a heating network is not economically viable, heat pumps and solar thermal energy are preferred.
• Central heating networks: In densely built and infrastructurally favorable areas, pipeline-bound solutions are being examined and expanded.

The strategy will be reviewed and updated every five years to adapt to technological advances and political framework conditions. In addition, the expansion of heating networks in the city center and industrial areas is prioritized.

## Division of the City Area into Heating Supply Zones

A central aspect of the March meeting was the detailed division of the city area into three categories:

1. Heating network suitability areas: In these areas, a heating network is economically and technically sensible. Examples include the old town and the Penzlinger Feld. Pilot projects and initial expansion stages are planned here.
2. Heating network evaluation areas: In these areas, further analyses are to be carried out to assess the suitability for heating networks. Here, technical, economic, and social factors must be weighed.
3. Individual supply areas: In these areas, decentralized solutions such as heat pumps and solar thermal energy are the preferred option.

The division was carried out using a utility value analysis that takes technical, economic, ecological, and social indicators into account. The results show that densely built and infrastructurally favorable areas are particularly suitable for central heating networks.

## Renewable Energy Sources and Technologies

Paderborn is relying on a broad range of renewable energy sources to decarbonize the heating supply:

• Geothermal energy: Both deep and shallow geothermal energy are used. Ground heat probes with a potential of 637.82 GWh/year are particularly promising.
• Waste heat: Industrial waste heat, especially in the areas of Mönkeloh and Schloss Neuhaus, offers a high potential.
• Photovoltaics: With a total potential of 1,780 GWh/year, PV is a key technology.
• Heat pumps: As the most efficient technology for using environmental heat, heat pumps are central to the heating transition strategy.

The city has also launched pilot projects for the use of river heat (Pader) and wastewater heat. These technologies will be further developed within the framework of heating network planning.

## Costs, Financing, and Risks

The implementation of the heating transition strategy is associated with considerable investment costs. The municipality plans to use funding from the federal and state governments and consider financing models such as project financing, crowdfunding, and citizen participation.

Challenges:

• Technical risks: Narrow, historical building structures complicate the construction of new pipelines.
• Legal risks: Water law requirements for river heat increase planning effort.
• Social risks: High coordination needs due to a heterogeneous ownership structure and limited site acceptance in the city center.

Despite these challenges, Paderborn is pursuing a gradual implementation that also takes into account financial resources and political priorities.

## Conclusion and Outlook

The March 2026 meeting marks another milestone on the way to climate neutrality in Paderborn. With a clear heating transition strategy, a detailed division of the city area, and the use of renewable energy sources, the city has laid a solid foundation for the coming years. The challenges are great, but the city's ambitions are impressive.

The next steps will show whether Paderborn can actually realize a climate-neutral heating supply by 2040 – not just as a goal, but as a lived project of the energy transition.
