ST Telemedia Global Data Centres (STT GDC) today published its 2025 Environmental, Social and Governance (ESG) Report, detailing how the Singapore-headquartered global data centre provider is meeting accelerating demand, including from AI-driven workloads, through infrastructure that is more resilient, efficient and sustainable by design. The report highlights 83.2% renewable energy usage, a 70.5% reduction in carbon intensity from its 2021 baseline, 41.2% improvement in water usage effectiveness (WUE) from the 2020 baseline, and continued progress in embedding ESG considerations into how STT GDC designs, builds, finances and operates its data centres at scale.
The report positions responsible growth as a core business discipline for STT GDC, linking sustainability performance to long-term asset resilience, customer trust and operational excellence. Across its global platform, STT GDC is integrating ESG considerations into capital allocation, site selection, design, operations, risk management and workforce development to support reliable digital infrastructure at scale. Bruno Lopez, President and Group Chief Executive Officer, ST Telemedia Global Data Centres, says, "The next phase of digital growth will be defined by how the industry resolves the tension between rising demand — particularly from AI — and the finite nature of energy, water and land. Responsible scaling is therefore not a sustainability commitment alone; it is a commercial and operational imperative that shapes where we build, how we design, and how we run our data centre platform."
STT GDC continued to advance its decarbonisation strategy in 2025, delivering measurable reductions in emissions and improvements in resource efficiency while scaling its global data centre platform to meet rising digital demand. Key environmental achievements include: furthered renewable energy adoption, with 83.2% of electricity consumption sourced from renewables, supporting STT GDC's transition towards carbon-neutral operations by 2030; reduced carbon intensity by 70.5% from the 2021 baseline, surpassing STT GDC's 2028 target three years ahead of schedule, alongside a 15.2% year-on-year reduction in absolute Scope 1 and 2 emissions; improved energy efficiency across operations, achieving an average Power Usage Effectiveness (PUE) of 1.44, a 13.0% improvement from the 2020 baseline; enhanced water stewardship, with Water Usage Effectiveness (WUE) improving by 41.2% from the 2020 baseline; and continued progress in sustainable infrastructure, with 48% of its data centres achieving green building certification.
As STT GDC continues to scale its global data centre platform, investing in people, safety and workforce capabilities remains central to delivering reliable and sustainable operations. Key social achievements include: maintained strong safety performance, with zero work-related fatalities and a Total Recordable Incident Rate (TRIR) of 0.1 across more than 41 million hours worked; strengthened workforce capability, with an average of 18 training hours per employee; advanced diversity and inclusion, with 21.7% women representation across the Group; expanded talent development initiatives, including the DC Power Up programme and partnerships with 10 Institutes of Higher Learning; and deepened community and workforce engagement through skills development programmes.
Strong governance, disciplined risk management and robust operational controls underpin STT GDC's ability to scale responsibly. Key achievements include: strengthened governance and ethical business practices, with 100% of employees completing anti-corruption training; enhanced enterprise-wide risk management, incorporating climate, cybersecurity and operational risks; advanced cybersecurity and operational resilience through initiatives such as executive-level cyber exercises; improved supply chain governance, embedding ESG criteria into procurement processes; and strengthened organisational alignment through the inaugural Group ESG Summit.
