NTT Global Data Centers Advances AI-Powered Cooling and Heat Reuse for Net-Zero Goals

NTT DATA, a global leader in digital business and technology services, announced the release of the first sustainability report for its data center division, NTT Global Data Centers.


The report highlights NTT DATA’s ongoing commitment to environmental stewardship and its accelerated progress toward achieving Net-Zero emissions within its data centers.


In FY23, NTT Global Data Centers achieved 51% renewable energy usage for non-IT load globally and secured 1.7 TWh of renewable energy through Power Purchase Agreements (PPAs) to support its transition to achieving Net-Zero emissions in our operations by 2030.


Global Sustainability Report Highlights


NTT Global Data Centers continues to drive measurable progress toward its Net-Zero goals with ambitious targets: achieving Net-Zero across Scope 1 and 2 emissions by 2030, and across Scope 1–3 by 2040, ten years ahead of the timeline of the Paris Agreement.


To improve efficiency and reduce environmental impact, NTT Global Data Centers is advancing AI-driven cooling technologies, optimizing Power Usage Effectiveness (PUE) across its facilities, and deploying battery energy storage systems to store renewable energy and enhance grid resilience, reducing reliance on fossil fuels during peak demand. These innovations ensure that as AI and digital demands grow, data center sustainability keeps pace.


NTT Global Data Centers’ sustainability initiatives continue to deliver real-world impact across its global operations:


Germany: Waste heat reuse of 2MW will supply heating and warm water to over 1,000 buildings in the Marienpark Berlin commercial district, reducing fossil fuel dependency and maximizing efficiency. Future plans include expanding this initiative to extract up to 37MW of thermal output of the campus in total. NTT Global Data Centers also recentlyannounced another new heat waste recovery project in Berlin that will supply 8MW of thermal waste heat from its data center to a residential district in Berlin.


United Kingdom: Implementation of a reverse osmosis filtration system reduced annual water usage by 35,000m³, cutting chemical waste and generating $120,000 in cost savings per year. Additionally, a smart sensor upgrade in U.K. data centers cut fan energy use by 50%, saving 2.6 GWh annually through optimized temperature and pressure settings, further enhancing energy efficiency and sustainability.


Mumbai, India: Deployment of liquid immersion cooling and direct contact liquid cooling improved energy efficiency by 30%, enabling high-density AI workloads while reducing power consumption.


Looking forward, NTT Global Data Centers is committed to deepening its impact by focusing on emissions reduction through renewable and low-carbon energy procurement and energy efficiency, circular economy principles, and innovative data center design development. The company is expanding its heat reuse initiatives, aiming to provide heating and warm water to even more buildings in multiple communities.


As the world’s third-largest data center provider, NTT Global Data Centers is backed by more than $10 billion in capital development through 2027 to drive future expansion of its data center business in current and new markets.
