Environment, Social & Governance

Our central role as a digital infrastructure and data centre services provider gives us a platform to contribute to a more sustainable society through innovation and the promotion of technological solutions.

ESG is at the heart of everything we do, the solutions we offer and the pioneering innovations we create.

Our Environmental, Social, Governance strategy comprises four pillars, with the concept of ESG by Design running throughout and digital trust, responsibility and governance wrapping around everything we do.
