Offenburg's Climate Protection and Biodiversity Strategy: A Month in Focus

Offenburg anchors climate protection and biodiversity firmly in urban development

In February 2026, the city of Offenburg further developed and implemented its Climate Protection and Biodiversity Strategy through several central decisions. With a clear focus on climate-neutral buildings, renewable energy, and the enhancement of biological diversity, Offenburg has demonstrated that the implementation of climate protection goals is feasible in practice – and what it looks like in concrete terms.

Climate protection concept: A roadmap for a climate-neutral community by 2040

Offenburg has set itself the goal of becoming climate-neutral by 2040. In February 2026, the Climate Protection Action Plan 2026/2027 was adopted, building on the existing Climate Protection Concept. The plan encompasses six key action areas, including "Sustainable Housing," "Climate Adaptation," and "Public Outreach."

Central to this is the reduction of greenhouse gas emissions through the replacement of fossil fuels with renewable energy sources. Heat pumps combined with photovoltaic systems are being installed in energy centers, and the district heating network is being expanded. The district heating lines in the core city are to be fully converted to renewable energy sources by 2040.

Another focal point is the renovation of municipal buildings. The Georg-Monsch School reduced its heating energy demand by 46%, and the Eichendorff School even achieved a 60% reduction compared to 2015. The city is also developing a roadmap for the climate-neutral renovation of its building stock.

Biodiversity: Flower meadows, nesting aids, and green spaces

Within the framework of the "Green and Biodiversity" action program, Offenburg has made significant progress in recent years. In February 2026, the program was reaffirmed and implemented in practice.

Since 2018, more than 5.3 hectares of flower meadow areas have been created in the core city. Extensive perennial meadows add up to approximately 6,800 m². The city is using native plants and integrating nesting aids for insects, birds, and bats.

Another highlight is the project "Natur nah dran," supported by the city. This initiative includes the use of native shrubs and wild perennials, as well as the installation of nesting aids for insects. These measures are being implemented at locations such as Stegermattstraße and Ahornallee.

In addition, Offenburg is involving the public in environmental projects. Over 16 schools and kindergartens participated in seeding actions, and the photo competition "In the Image of Nature" promotes awareness of biodiversity.

Energy report 2024: Progress and challenges

The 2024 Energy Report provides a detailed overview of the energy consumption of municipal buildings from 2022 to 2024. The heat consumption decreased from 14.5 million kWh in 2021 to 12.6 million kWh in 2024 – a clear success attributable to optimizations and the expansion of the district heating network.

Electricity consumption, however, rose to 4.1 million kWh (2024), partly due to the use of heat pumps and IT infrastructure. At the same time, the share of renewable energy is increasing: photovoltaic systems now generate 297,000–319,000 kWh per year, with the self-generated electricity share at about 7%.

The city is working on a new energy strategy that includes the expansion of photovoltaic systems and the digitalization of its energy management system. A new energy management system will enable more precise real-time monitoring of energy consumption in the future.

Climate adaptation: From heat plans to tree planting

Climate adaptation is a central component of urban development. In February 2026, an emergency plan for heatwaves was developed in collaboration with the Karlsruhe Institute of Technology (KIT). The plan includes action briefs for heat-vulnerable groups and a communication cascade for heat warnings.

Another focus is tree planting. Climate-adapted trees have been planted along Werderstraße and Zepplinstrasse, and the city plans a tree-lined avenue along the bike path towards Fessenbach. In addition, a mini-forest is being created on the forecourt of the Evangelical City Church.

Conclusion: Offenburg as a model for climate protection and sustainability

February 2026 shows that Offenburg is on the right path to achieving its climate protection goals. With a combination of technical measures, public participation, and long-term planning, the city has developed a clear guideline for a climate-neutral future. Implementation remains a challenge, but the developments in Offenburg demonstrate that it is possible – and that a sustainable urban environment invites all citizens to live well.
