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, and a 41.2% improvement in water usage effectiveness (WUE) from the 2020 baseline. These achievements position the company to meet accelerating demand, including from AI-driven workloads, through infrastructure that is more resilient, efficient, and sustainable by design.
The report underscores responsible growth as a core business discipline, 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 of ST Telemedia Global Data Centres, emphasized that 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. He stated, “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.”
Key environmental achievements in 2025 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, achieving an average Power Usage Effectiveness (PUE) of 1.44, a 13.0% improvement from the 2020 baseline. Water stewardship advanced 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 sustainability integration across facility lifecycles.
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 included the DC Power Up programme and partnerships with 10 Institutes of Higher Learning across its markets.
In governance, STT GDC strengthened enterprise-wide risk management, incorporating climate, cybersecurity, and operational risks into planning and decision-making. The company reported that 100% of employees completed anti-corruption training, and it enhanced cybersecurity through executive-level cyber exercises and risk assessments. Supply chain governance was improved by embedding ESG criteria into procurement processes.
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.
