ST Telemedia Global Data Centres (STT GDC) today published its 2025 Environmental, Social and Governance (ESG) Report, highlighting significant progress in responsible scaling. The Singapore-headquartered global data centre provider reported 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 continued progress in embedding ESG considerations into its operations. These achievements underscore the company's ability to meet accelerating demand, including from AI-driven workloads, through infrastructure that is more resilient, efficient and sustainable by design.
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, stated, "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."
Key environmental achievements include furthering renewable energy adoption, with 83.2% of electricity consumption sourced from renewables, supporting STT GDC's transition towards carbon-neutral operations by 2030. The company reduced carbon intensity by 70.5% from the 2021 baseline, surpassing its 2028 target three years ahead of schedule, alongside a 15.2% year-on-year reduction in absolute Scope 1 and 2 emissions. Energy efficiency improved across operations, achieving an average Power Usage Effectiveness (PUE) of 1.44, a 13.0% improvement from the 2020 baseline. Water stewardship enhanced with WUE improving by 41.2% from the 2020 baseline, supported by a balanced approach to managing energy and water use in cooling systems. Additionally, 48% of its data centres achieved green building certification, reflecting the integration of sustainability considerations across the lifecycle of its facilities.
On the social front, STT GDC 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. The company strengthened workforce capability with an average of 18 training hours per employee and advanced diversity and inclusion with 21.7% women representation across the Group. Talent development initiatives include the DC Power Up programme and partnerships with 10 Institutes of Higher Learning across its markets.
In governance, STT GDC reinforced its commitment to integrity with 100% of employees completing anti-corruption training. The company enhanced enterprise-wide risk management, incorporating climate, cybersecurity and operational risks into planning and decision-making. It also advanced cybersecurity and operational resilience through initiatives such as executive-level cyber exercises and risk assessments, and improved supply chain governance by embedding ESG criteria into procurement processes. The inaugural Group ESG Summit supported capability building and consistent application of ESG priorities across markets.
These efforts come as data centre operators face growing expectations to deliver capacity while managing energy, water, climate and cybersecurity risks with greater transparency and accountability. The full 2025 ESG Report is available at https://www.sttelemediagdc.com/about-us/our-esg-progress.
