Aarhus, Denmark, is one of the 112 cities participating in the EU Mission to establish 100 climate-neutral and smart cities. Under the Pilot Cities Programme, Aarhus is piloting innovative climate initiatives in Spárring, a peri-urban community, aiming for rapid decarbonization through the CO-SHAPE project. This initiative focuses on creating a 1000-hectare circular energy park that integrates multiple renewable energy sources and storage solutions while reimagining governance and citizen engagement.

Led by Martin Kaae Riis, the project emphasizes a holistic approach to land use and energy systems, targeting a reduction of over 100,000 tonnes of CO2 equivalent annuallyãpproximately 10% of Aarhus' total emissions. Key components include biogas production from agricultural residues, a pyrolysis plant for biochar, and future plans for solar power and energy storage.

A significant innovation in CO-SHAPE is the participatory planning process, termed "solution rooms," where local citizens, landowners, and energy developers collaborate from the outset to shape the project's trajectory. This contrasts with traditional planning methods, which often exclude community input until later stages.

Riis emphasizes that addressing complex societal challenges requires a shift in governance culture and fostering trust among stakeholders. The pilot project aims not only for technological advancements but also for institutional changes that embed co-creation principles into the cityás climate action framework.

Ultimately, the CO-SHAPE initiative showcases how integrated spatial planning and innovative governance can drive systemic change, setting a precedent for future urban climate strategies. By promoting a collaborative environment, Aarhus aims to transform the green transition from a top-down imposition into a collective journey shaped by community involvement.
