NTT Global Data Centers as a Green Data Center Provider
NTT Global Data Centers (NTT GDC) is a major player in the digital infrastructure industry, recognized for its ambitious sustainability goals and innovative approach to reducing the environmental impact of its operations. As the world’s third-largest data center provider, NTT GDC is actively aligning its rapid expansion and technological advancements-especially in AI-with a robust environmental strategy.
Net-Zero and Emissions Reduction Targets
NTT GDC has set clear and ambitious targets:
Achieve net-zero emissions across its direct operations (Scope 1 and 2) by 2030.
Reach net-zero across its entire value chain (Scope 1, 2, and 3) by 2040, a decade ahead of the Paris Agreement timeline.
These targets are guided by the Science Based Targets initiative (SBTi) and the United Nations’ Sustainable Development Goals (SDGs), ensuring NTT’s approach is both credible and globally relevant.
Renewable Energy and Energy Efficiency
NTT GDC is accelerating its renewable energy transition:
In FY23, it achieved 51% renewable energy usage for non-IT loads globally, securing 1.7 TWh of renewable energy through power purchase agreements (PPAs).
The company has increased its investment in renewables by 25% and reduced operational emissions by 25% compared to FY21.
Advanced AI-driven cooling technologies and battery energy storage systems (BESS) are being deployed to optimize power usage effectiveness (PUE) and enhance grid resilience.
Innovative Cooling and Resource Management
NTT GDC is at the forefront of deploying alternative cooling technologies:
Liquid Immersion Cooling (LIC) and Direct Contact Liquid Cooling (DCLC) have been implemented in Mumbai, India, improving energy efficiency by 30% and enabling high-density AI workloads while reducing power consumption.
In the UK, smart sensor upgrades have cut fan energy use by 50%, saving 2.6 GWh annually.
In Austria, NTT GDC uses HVO100 (100% hydrotreated vegetable oil) as a renewable backup generator fuel, reducing greenhouse gas and particulate emissions significantly.
Circular Economy and Heat Reuse
NTT GDC’s sustainability strategy includes circularity and community impact:
Waste heat reuse projects in Germany supply heating and hot water to thousands of buildings, with plans to scale up to 37MW of thermal output in Berlin alone.
The company encourages recycling, reusing waste, and purchasing lower-carbon materials throughout its supply chain.
Water Stewardship
Water efficiency is a priority:
In the UK, a reverse osmosis filtration system reduced annual water usage by 35,000 m³, cutting chemical waste and saving $120,000 per year.
Continuous optimization of energy and water efficiency is built into daily operations.
Transparency and Reporting
NTT GDC’s 2025 Global Sustainability Report details its progress and outlines a holistic framework for decarbonization, energy efficiency, and social responsibility. The company regularly benchmarks its performance and shares results with stakeholders.
