CoreWeave and Conapto Partner for Sustainable AI Cloud Expansion in Stockholm

In a significant move for sustainable digital infrastructure, CoreWeave has joined forces with Swedish data center operator Conapto to launch two new AI cloud campuses in Stockholm. This collaboration, detailed in an article published on June 30, 2026, aims to expand Europe's AI cloud capacity while strictly adhering to environmental sustainability principles. The partnership underscores a growing industry trend towards integrating green practices into high-demand computing operations, particularly those driven by artificial intelligence. The new Stockholm facilities are designed to operate exclusively on renewable energy, aligning with broader European mandates for eco-friendly technology adoption. This commitment to 100% renewable power sources is crucial for minimizing the environmental impact of training and running large foundation models, which are known for their substantial energy consumption. The initial capacity at the Stockholm 4 South facility is already operational, marking a swift deployment of this sustainable infrastructure. Beyond renewable energy, a standout feature of this partnership is Conapto's innovative approach to waste heat recovery. Instead of simply venting the thermal energy produced by the AI compute clusters, the data centers are equipped with mechanical systems that capture this heat. This recovered energy is then channeled into the municipal infrastructure, directly supporting Stockholm's district heating network. This closed-loop system transforms what would typically be a waste byproduct into a valuable resource, further enhancing the environmental credentials of the project and contributing to the local community's energy needs. Håkan Björklund, CEO of Conapto, highlighted that this partnership exemplifies how advanced AI infrastructure can seamlessly integrate with sustainability objectives. The collaboration provides AI developers with access to CoreWeave Cloud, ensuring that the increasing demand for AI processing power in Europe is met with resilient, high-density infrastructure that also champions environmental responsibility. This initiative sets a precedent for future AI cloud deployments, demonstrating that high performance and ecological stewardship can indeed go hand-in-hand.
