The detailed breakdown of our GRESB assessment reveals consistent excellence across all three core pillars of evaluation:
Environmental excellence
Our environmental score of 21 out of 23 surpasses the peer group average of 19, reflecting our commitment to reducing environmental impact through innovative technologies, energy efficiency measures, and sustainable operational practices. This achievement demonstrates our proactive approach to environmental stewardship within the energy-intensive data centre industry.
Social responsibility leadership

Governance strength
Our governance score of 23 out of 24 far exceeds the peer group average of 17, showcasing our robust corporate governance frameworks, transparency, and accountability measures. This score reflects our commitment to ethical business practices and responsible corporate citizenship.
A holistic approach to sustainability
What makes these results particularly meaningful is the comprehensive nature of the GRESB assessment, which is based on a thorough examination of our entire business ecosystem.
The assessment encompasses client interactions, examining how we engage with our clients and deliver value whilst maintaining sustainable practices.
Health and safety protocols form a crucial component of the assessment, reflecting our commitment to creating safe working environments and protecting the wellbeing of our employees, contractors, and visitors. Our leadership practices are scrutinised to ensure they demonstrate genuine commitment to sustainability integration at all organisational levels.
Day-to-day operations receive particular attention, as these reflect the practical implementation of our sustainability policies and demonstrate whether our commitments translate into meaningful action across all business functions.
Continuous improvement and future commitments
Whilst we’re celebrating these outstanding results, they also reinforce our commitment to continuous improvement. The slight gaps between our scores and the maximum possible points highlight opportunities for further enhancement across all areas of our operations.
Our 2025 GRESB results validate our comprehensive approach to sustainable business practices whilst motivating us to maintain our leadership position through ongoing innovation and operational excellence.
These achievements reflect the dedication of our entire team, whose daily efforts to integrate sustainability principles into every aspect of our operations have created measurable value for our stakeholders and the broader data centre industry.
As we move forward, these results provide a solid foundation for continued leadership in sustainable data centre operations, demonstrating that environmental responsibility and business excellence go hand in hand at Datum Datacentres.
