London,UK February 25th 2026 – Colt Technology Services (Colt), the global digital infrastructure company, today announced independent recognition for its journey to sustainability as it secures two outstanding ESG ratings. Colt secured a Platinum rating from EcoVadis for the fourth consecutive year and a CDP Climate Change Score of A-for the third year in a row.
EcoVadis is the world’s largest and most trusted sustainability ratings provider, with Platinum the highest achievable rating reserved for just 1% of all rated companies globally. Colt achieved a score for 2025 of 86 out of one hundred, marking a five-point improvement from the previous year and positioning Colt among the top-performing companies in its sector. Colt has scored a Platinum rating consistently for the past four years.
The CDP (formerly the Carbon Disclosure Project) Climate Change Score is a global rating that evaluates how well a company measures, manages and reports its climate-related risks, emissions and strategy and is widely considered one of the most trusted benchmarks for corporate climate transparency. Colt has secured one of the top ratings - an A- Climate Change Score - for the third consecutive year, maintaining a score above the global industry average and surpassing the global category average across many of the key assessment areas.
Caroline Griffin Pain, chief legal officer, ColtTechnology Services, said, “Sustainability is built into every decision we make. We’re transparent, we're ambitious and we measure our performance against world‑class standards. Our fourth consecutive Platinum EcoVadis rating and third A- CDP score prove our long‑term commitment to making a meaningful difference for our customers and the planet.”
