ST Telemedia Global Data Centres (STT GDC) today published its 2025 Environmental, Social and Governance (ESG) Report, announcing it has surpassed its 2028 carbon intensity target three years early. The report details how the Singapore-headquartered data centre provider is meeting accelerating demand, including from AI-driven workloads, through infrastructure that is more resilient, efficient and sustainable by design.
Key environmental achievements include 83.2% renewable energy usage, a 70.5% reduction in carbon intensity from its 2021 baseline, a 41.2% improvement in water usage effectiveness (WUE) from the 2020 baseline, and an average Power Usage Effectiveness (PUE) of 1.44, a 13.0% improvement from the 2020 baseline. The company also noted that 48% of its data centres have achieved green building certification.
Bruno Lopez, President and Group Chief Executive Officer of STT GDC, said, "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."
On the social front, STT GDC reported zero work-related fatalities and a Total Recordable Incident Rate (TRIR) of 0.1 across more than 41 million hours worked. The company provided an average of 18 training hours per employee and achieved 21.7% women representation across the Group. Talent development initiatives include the DC Power Up programme and partnerships with 10 Institutes of Higher Learning.
In governance, 100% of employees completed anti-corruption training, and the company strengthened enterprise-wide risk management incorporating climate, cybersecurity and operational risks. Supply chain governance was enhanced by embedding ESG criteria into procurement processes. The inaugural Group ESG Summit supported capability building across markets.
