STT GDC sources 83.2% of electricity from renewables

The data centre operator is working towards carbon-neutral operations by 2030.

ST Telemedia Global Data Centres (STT GDC) said renewable sources accounted for 83.2% of its electricity consumption in 2025 as it works towards carbon-neutral operations by 2030.

The data centre operator reduced its carbon intensity by 70.5% from its 2021 baseline, exceeding its 2028 target three years early, according to its environmental, social and governance report.

Absolute Scope 1 and Scope 2 emissions fell 15.2% year-on-year, it added.

Scope 1 covers emissions from sources controlled by the company, whilst Scope 2 covers indirect emissions from purchased energy.

STT GDC recorded an average power usage effectiveness of 1.44, representing a 13% improvement from its 2020 baseline.

The operator said that the metric measures the total energy used by a data centre relative to the energy consumed by its computing equipment, with a lower figure indicating greater efficiency.

Meanwhile, water usage effectiveness improved by 41.2% from the 2020 baseline. The company said 48% of its data centres had obtained green building certification.

A NOTE FROM SINGAPORE BUSINESS REVIEW

If you've been wondering whether SBR could work for your company — yes, probably.

A lot of the companies we partner with started as readers. They'd been following our coverage for a while, saw their own customers and competitors in it, and eventually asked the obvious question: could we do something with you? The answer is usually yes. The shape of it depends on what you're trying to do.

The options are broader than most people assume — thought leadership articles, sponsored content, industry summits across Southeast Asia, regional awards programmes, podcasts, and media placements in print and digital. Some partners use one channel; most use a mix. We figure out the right combination by starting with your brief, not with our rate card.

So if the question has been on your mind, here's the easy way to ask it.

We'll tell you honestly whether we can help, and how. It's a better use of everyone's time.
