Germany eases data centre heat rules to boost AI, risking climate backlash

Germany aims to double its data centre fleet and quadruple AI compute capacity by 2030, seeking to reduce reliance on the US and support its economy. However, the original Energy Efficiency Act, which required new data centres to recycle waste heat, faced strong industry opposition. Developers argued that the rules could make new projects unviable if there was no local demand for recycled heat. In response, the government amended the bill so operators only need to assess feasibility, not guarantee heat reuse.

Industry figures say this change could revive stalled data centre projects, making Germany more attractive for digital infrastructure investment. Yet critics, including former officials, warn that relaxing the rules may undermine Germany’s climate commitments and invite public opposition. Recent local decisions in Germany have already blocked major data centre projects over environmental concerns.

For banks, insurers and pharma companies, the amended rules may ease access to domestic AI infrastructure but create uncertainty around future environmental compliance. The balance between digital growth and climate targets remains unsettled, with further regulatory shifts likely as public scrutiny increases.
