SINGAPORE – Media OutReach Newswire – 21 July 2026 – ST Telemedia Global Data Centres (STT GDC) today published its 2025 Environmental, Social and Governance (ESG) Report, setting out 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. 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. As we scale further, we will continue to advance with the same discipline — in the infrastructure we build, the governance that underpins it, and the positive impact we create for the communities and ecosystems we are part of.”
Scaling efficient, lower-carbon infrastructure
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. The Group’s approach focuses on embedding sustainability into the design and operation of its infrastructure, enabling long-term performance while managing growing energy and resource requirements. 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, reflecting continued optimisation of data centre design and operations.
Enhanced water stewardship, with Water Usage Effectiveness (WUE) improving by 41.2% from the 2020 baseline, supported by a balanced approach to managing energy and water use in cooling systems.
Continued progress in sustainable infrastructure, with 48% of its data centres achieving green building certification, reflecting the integration of sustainability considerations across the lifecycle of its facilities.
Building a safe and future-ready workforce
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. In 2025, the Group maintained a strong focus on safeguarding its workforce, strengthening organisational capability and supporting the development of future-ready talent to meet the growing demands of the digital economy. 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, reflecting robust health and safety management across construction and operations.
Strengthened workforce capability, with an average of 18 training hours per employee, supporting the development of technical, operational and leadership skills across the organisation.
Advanced diversity and inclusion, with 21.7% women representation across the Group, reinforcing ongoing efforts to build a more inclusive and balanced workforce.
Expanded talent development initiatives, including the DC Power Up programme and partnerships with 10 Institutes of Higher Learning across our markets, helping to build a pipeline of industry-ready talent for the growing digital infrastructure sector.
Deepened community and workforce engagement, through skills development programmes and industry-academic partnerships that support long-term talent development and contribute to local economic growth.
Strengthening Governance and Resilience at Scale
Strong governance, disciplined risk management and robust operational controls underpin STT GDC’s ability to scale responsibly in an increasingly complex digital environment. In 2025, the Group continued to strengthen its enterprise-wide approach to governance, embedding ESG considerations into decision-making, risk management and day-to-day operations to support long-term resilience and performance. Key achievements include:
Strengthened governance and ethical business practices, with 100% of employees completing anti-corruption training, reinforcing STT GDC’s commitment to integrity and accountability across its global operations.
Enhanced enterprise-wide risk management, incorporating climate, cybersecurity and operational risks into planning and decision-making, ensuring infrastructure resilience as the Group scales.
Advanced cybersecurity and operational resilience, including strengthened governance, technical controls and preparedness through initiatives such as executive-level cyber exercises and risk assessments across key facilities.
Improved supply chain governance, embedding ESG criteria into procurement processes and reinforcing responsible sourcing practices across its global vendor network.
Strengthened organisational alignment and execution, through the inaugural Group ESG Summit, supporting 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.
STT GDC’s 2025 ESG Report reflects a continued evolution in how the Group approaches sustainable growth, with a stronger focus on disciplined execution, operational resilience and long-term performance as it scales its global platform. As digital infrastructure becomes increasingly critical to economies and societies, STT GDC will continue to embed sustainability, risk management and governance into how it designs, builds and operates its data centres.
