C40 Cities Launches Global Pact for Greener Data Centres

In a significant move towards mitigating the environmental impact of digital infrastructure, C40 Cities has launched the Global Urban Data Centres Pact. This initiative establishes a unified vision among mayors for the development of sustainable urban data centers, structured around four fundamental pillars: strategic city integration, resource efficiency, accountability, and shared prosperity. A core commitment of the pact requires participating mayors to ensure that data center energy demands are met solely through new renewable energy generation, explicitly prohibiting the construction of new fossil-fuel power plants or the reopening of existing ones for this purpose. This commitment underscores a dedication to transitioning away from carbon-intensive energy sources for digital operations. Beyond energy, the pact emphasizes best-in-class water-use standards, aiming to prevent reliance on potable water sources. It actively encourages the capture and reuse of waste heat generated by data centers, transforming it into a valuable resource for community benefit. Furthermore, cities signing the pact pledge to publish measurable sustainability and public health benchmarks, ensuring transparency and progress tracking. Revenue generated from fair-share pricing mechanisms will be directed towards local sustainability and social infrastructure initiatives, fostering a symbiotic relationship between technological growth and community welfare. This comprehensive approach demonstrates how cities are actively working to align the expansion of digital infrastructure with pressing climate goals, responsible resource management, and broader community benefits, setting a new standard for urban data center development.
