ST Telemedia Global Data Centres (STT GDC) today published its 2025 Environmental, Social and Governance (ESG) Report, highlighting significant progress in responsible scaling amid surging demand for digital infrastructure, particularly from AI-driven workloads. The Singapore-headquartered global data centre provider reported a 70.5% reduction in carbon intensity from its 2021 baseline, surpassing its 2028 target three years ahead of schedule, with 83.2% of electricity consumption sourced from renewables.
The report underscores STT GDC's commitment to integrating sustainability into core business operations. Key environmental achievements include a 41.2% improvement in water usage effectiveness (WUE) from the 2020 baseline and an average Power Usage Effectiveness (PUE) of 1.44, representing a 13.0% improvement from the 2020 baseline. Additionally, 48% of its data centres have achieved green building certification, reflecting lifecycle sustainability integration.
Bruno Lopez, President and Group Chief Executive Officer of STT GDC, emphasized that responsible scaling is a commercial and operational imperative. "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 said. "Our 2025 progress reflects disciplined execution of a strategy we have been advancing for years, delivering meaningful improvements in energy efficiency, emissions and resource management across our global platform."
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 provided an average of 18 training hours per employee and advanced diversity 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 to build a pipeline of industry-ready talent.
In governance, STT GDC strengthened enterprise-wide risk management, incorporating climate, cybersecurity and operational risks into planning. All employees completed anti-corruption training, and the company enhanced supply chain governance by embedding ESG criteria into procurement processes.
