Cooling Under Pressure: Navigating the sustainability-cooling nexus in modern data centres 

The region's higher temperatures and requirements for additional cooling drive up PUEs, making sustainability an additional challenge. Despite pushback on sustainability, it remains crucial to many leading customers and operators of data centres. 

• Is liquid cooling the inevitable future—or are hybrid and passive systems viable alternatives? 
• How are operators managing the energy-water-carbon trade-offs in cooling strategy? 
• How are suppliers addressing water scarcity and regulatory constraints? 
• What role do heat reuse, smart materials, and predictive maintenance play?
