Top 10 Most Sustainable Data Centre Operators

Data centres are one of the most critical infrastructures. We’re taking a look at 10 of the most sustainable data centre operators, in no particular order

Data centres are still one of the most important and critical business infrastructures in the world. However, as we continue to produce and consume more data than ever, it's becoming more important for data centre operators to become more sustainable. Their impact on the environment has not gone unnoticed and with COP26 now coming to an end, there is a real push for the industry to do better. 

Below, we’re taking a look at 10 of the most sustainable data centre operators, in no particular order, who are making great efforts to become more sustainable in order to help minimise their environmental impact. 




AirTrunk was founded in 2015 and their vision is ‘to continuously redefine and deliver the hyperscale data centres of tomorrow, in order to meet the needs of the world’s most influential technology companies today and into the future’. They deliver the lowest PUE in the Asia-Pacific region through efficient design and operations as well as optimising their water efficiency through water conservation strategies for all of their operational data centres. They are also aligned to the United Nations Sustainable Development Goals and the Paris Climate Agreement.


Scala Data Centers


Scala Data Centers is Latin America’s leading, sustainable hyperscale data centre operator. Founded in 2020, their mission is to ‘support Latin America in the construction and operation of the necessary infrastructure for the evolution of countries to a new level of digitalization’. They believe that a company’s success should be measured not only by its financial results, but also by its commitment to the environment, it’s ethical behaviours and its contributions to society. They have reduced their environmental impact by obtaining renewable energy and in doing so they have become the first data center operator in the LATAM region to use 100% renewable and certified energy.




Echelon are a Dublin based data centre owner, developer and operator who are building large-scale data centre campuses across Europe to meet the expanding global demand for data processing and storage solutions. They have also realised the importance of sustainability in recent years and are dedicated to developing ‘halfway house’ solutions in the short to medium term to help mitigate the environmental impact of the industry. For example, they will use waste heat at their DUB20 site to dry the by-products to produce valuable fertiliser for agriculture and their LCY10 site in London Docklands will use the adjacent dock resource as a heat exchange to reduce the energy consumption of the data centre.


Ark Data Centres


Ark Data Centres design, build and operate the UK’s most efficient data centres. They are committed to leading the industry in reducing the environmental impacts and are dedicated to taking steps to minimise any negative impacts. The company maintains an environmental management system that reflects their business requirements and they continually seek to improve the effectiveness of the systems in order to reduce environmental impact.

They are also minimising toxic emissions through the careful selection and use of machinery and promoting recycling both internally and externally amongst clients, suppliers and visitors.
