Colt DCS Reports 27% Reduction in Greenhouse Gas Emissions

• Delivered 27% reduction in greenhouse gas emissions in Scope 1, 2 (market based) and 3 compared to 2019 base year
• Achieved 100% renewable electricity in Scope 2 and 90% renewable share of total energy consumption (Scopes 1, 2 and 3).
• Advanced Global Reference Design (GRD), embedding lower-carbon materials, energy-efficient systems, and near-zero wastewater cooling into new architectural developments.

LONDON, June 25, 2026 /PRNewswire/ -- Colt Data Centre Services (Colt DCS), a global provider of AI-ready, hyperscale and large enterprise data centre solutions, today announced the publication of its fourth annual Sustainability Report. 

The report outlines the company's sustainability performance over 2025 and includes data across its environmental, social, and governance (ESG) material topics, identified and prioritised through a Double Materiality Assessment conducted in 2024.

It reveals that Colt DCS has delivered a 27% reduction in greenhouse gas emissions in Scope 1, 2 (market-based) and 3 compared to the 2019 base year. 

Last year, the data centre provider also sourced 100% renewable electricity in Scope 2, through renewable energy certificates, and a 90% renewable share of total energy consumption (Scopes 1, 2 and 3).

This reduction reflects the company's continued commitment to decarbonising the design, development, and operation of its data centres. 

Building on this approach, Colt DCS advanced its Global Reference Design (GRD) in 2025, further developing a repeatable, standardised blueprint that is flexible enough to adapt to local requirements while maintaining consistency in its core principles across future developments. The GRD embeds energy-efficient systems, lower embodied carbon materials and near-zero wastewater cooling technologies into all new data centre architecture, while targeting an annualised PUE below 1.2 and waste diversion rates of 75% in construction and demolition and 90% in operations.

Addressing water use, the GRD incorporates chilled water systems using low-GWP refrigerants with near-zero water consumption, alongside rainwater harvesting for non-potable indoor use. Closed-loop liquid cooling systems circulate coolant in a sealed loop, transferring heat without relying on evaporation.

Further key features from the 2025 Sustainability Report include:

• Achieved the Great Place To Work certification, with 92% of employees recommending Colt DCS as a top employer (up from 87% in 2024).
• Won The Best Talent Developer of the Year at the Data Centre World Awards.
• Attained TRUE Zero Waste certification across 3 sites, including London North, Tokyo Inzai 1-3 and Osaka Keihanna.
• Reached a global PUE of 1.41.
• Secured ISO 27001 Information Security Management System certification globally, and ISO 14001 Environmental Management System certification across the UK and Europe.

Anthea van Scherpenzeel, Head of Environmental Sustainability at Colt DCS, stated:

"We are proud of the progress made in reducing absolute emissions in 2025 as we continue advancing towards our 2045 net zero target. Whole life carbon assessments are helping customers and partners identify key sources of value-chain emissions and understand the impact of design and procurement decisions. Through close collaboration with suppliers and industry partners, we are confident we can continue delivering projects at speed and scale while making steady progress towards our SBTi targets."

Dina Nassar, Sustainability Analyst at Colt DCS, added:  "As the growth of AI introduces new efficiency challenges for data centre operators across the globe, we continue to advance how we design, build and operate our data centres. Our revised GRD underpins the efficiency gains made in 2025, by ensuring lower embodied carbon materials and advanced cooling technologies are baked in at the design stage."

Colt DCS Reports 27% Reduction in Greenhouse Gas Emissions

GUIYANG, China, June 25, 2026 /PRNewswire/ -- A news report by Huanqiu.com

From June 14 to 19, Guiyang Confucius Academy leveraged the festive occasion to host a rich array of Dragon Boat Festival activities including folk custom experiences, international cultural exchanges, cultural and creative product launches, and immersive site tours. These interactive offerings bring traditional culture closer to the public and add profound humanistic charm to the city brand of "Cool Guiyang".

On June 14, international students of various nationalities from Guizhou Medical University visited Guiyang Confucius Academy and kicked off the event with a 24-style Tai Chi demonstration. Chen Xin (transliterated), a student from Pakistan, had only learned about the Dragon Boat Festival through reading previously. After weaving a bamboo boat by hand under the guidance of an intangible cultural heritage inheritor, he came to understand that the festival features more than rituals and delicacies, and bears profound humanistic heritage.

At the event, lecturers from Guiyang Confucius Academy integrated Dragon Boat Festival folk traditions with Confucian teachings. Illustrating Qu Yuan's moral integrity and the collective spirit of dragon boat culture, they guided international students to uphold virtue, pursue goodness, and foster loyalty to family and country.

Meanwhile, the modern transformation of traditional culture is newly embodied in cultural creations. As night breezes glide through the dancers' sleeves at Longchang Post Station and ripples of the Wuyang River reflow in paper-cut lanterns, the spiritual pursuit of five centuries ago is infused with contemporary warmth. On June 18, the Yangming cultural and creative space "Guizhou's Twelve Scenes of Enlightenment" was officially launched. The scenario dance drama "Guizhou's Twelve Scenes of Enlightenment: Enlightenment and Spiritual Inheritance" recreates iconic scenes through dance, including Wang Yangming's enlightenment in Longchang, academic preaching in Guiyang, and literary legacy in Zhenyuan.

Beyond the stage, over 20 original cultural and creative products integrate Wang Yangming's ideological heritage into daily life. The tea gift sets feature twelve hand-painted landscape scrolls, with exclusive aesthetics and connotations corresponding to each scene. Zhenyuan paper-cut lanterns overlay light and shadow that echo the ancient charm of the Wuyang River and Qinglong Ancient Town. Brass paperweights inscribed with Record of the Elephant Shrine replicate the timeless classic, bringing peace and serenity to the study space. Daily items including postcards, fridge magnets and tap night lights subtly embed Wang Yangming's philosophies of "Nothing exists outside the mind" and "The unity of knowledge and action" into everyday life.

Dai Jianwei, Director of Guiyang Confucius Academy Cultural Communication Center, stated that "Guizhou's Twelve Scenes of Enlightenment" shall step out of history and integrate into modern life, offering citizens perceptible and touchable cultural experiences. Up to now, five cultural and creative venues have opened their doors, namely Cuiwei Garden at Jiaxiu Tower, the Former Site of Dade School, and Fuquan Intangible Cultural Heritage Inheritance & Exhibition Hall.

On June 19, the themed activity "Guizhou's Twelve Scenes of Enlightenment: A Refreshing Dragon Boat Festival Tour" brought the celebration to a crescendo. The immersive story-based garden quest stood out as the prime attraction. Twelve scene seals match the twelve landmarks that Wang Yangming visited during his sojourn in Guizhou. Visitors carrying a ceremonial Pass Scroll kick off their journey with herb identification and herbal tea tasting.

On the same day, eleven departments of the First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine co-hosted free medical consultations. Treatments such as acupuncture, auricular plaster therapy and cupping moxibustion connect age-old Dragon Boat customs of fending off diseases with professional healthcare services. Local resident Yuan Jing made a special trip with her kid, noting that only through witnessing and creating things by their own hands can children fully comprehend the profound meaning of the festival.

This six-day Dragon Boat Festival program links tradition to the present via three highlights: cultural exploration by overseas young participants, innovative development of Yangming cultural creations, and immersive experiences open to locals and visitors. It reveals that traditional culture is inherently vibrant; its lasting vitality lies in rediscovery, sincere storytelling and hands-on heritage inheritance.
