ST Telemedia Global Data Centres (STT GDC) announced today that it has surpassed its 2028 carbon intensity reduction target three years ahead of schedule, achieving a 70.5% reduction from its 2021 baseline. The milestone was detailed in the company's 2025 Environmental, Social and Governance (ESG) Report, which also highlighted that 83.2% of its electricity consumption now comes from renewables, positioning the Singapore-headquartered data centre provider to meet carbon-neutral operations by 2030.
The report underscores how STT GDC is balancing rapid expansion—particularly driven by artificial intelligence workloads—with sustainability. Bruno Lopez, President and Group Chief Executive Officer, stated that "responsible scaling is therefore not a sustainability commitment alone; it is a commercial and operational imperative." The company improved Power Usage Effectiveness (PUE) by 13.0% from its 2020 baseline to an average of 1.44, and Water Usage Effectiveness (WUE) improved by 41.2% from the 2020 baseline. Additionally, 48% of its data centres now hold green building certifications.
These environmental gains come as the company scales its global platform to meet rising digital demand. The report emphasizes that STT GDC is integrating ESG considerations into capital allocation, site selection, design, operations, risk management, and workforce development. Absolute Scope 1 and 2 emissions fell 15.2% year-on-year, even as the company expanded.
On the social front, STT GDC maintained zero work-related fatalities and a Total Recordable Incident Rate (TRIR) of 0.1 across more than 41 million hours worked. Employees received an average of 18 training hours, and women now represent 21.7% of the workforce. Talent development initiatives, including the DC Power Up programme and partnerships with 10 Institutes of Higher Learning, aim to build a pipeline of industry-ready talent for the digital infrastructure sector.
Governance and resilience also saw advances. The company reported 100% of employees completed anti-corruption training, and it strengthened enterprise-wide risk management incorporating climate, cybersecurity, and operational risks. Supply chain governance was improved by embedding ESG criteria into procurement processes. STT GDC also held its inaugural Group ESG Summit to align priorities across markets.

The company operates across Singapore, the UK, Germany, Italy, India, Thailand, South Korea, Indonesia, Japan, the Philippines, Malaysia, and Vietnam. As data centre operators face growing expectations to deliver capacity while managing energy, water, climate, and cybersecurity risks, STT GDC's report positions responsible growth as a core business discipline linked to long-term asset resilience, customer trust, and operational excellence.
