That is why we are committed to a responsible and caring approach to development, playing our part in delivering a shared and prosperous future. Environmental sustainability at CloudHQ is grounded in engineering rigor and operational excellence, focusing on measurable outcomes across the full facility lifecycle.
CloudHQ employs innovative cooling approaches that save millions of gallons of water annually. The hybrid heat rejection cooling architecture deployed at facilities today is reflective of this approach which combines the best attributes of air-cooled and water-cooled systems to maximize both energy efficiency and water preservation.
By dynamically adjusting cooling modes based on seasonal conditions and local environmental constraints, CloudHQ facilities operates at low-to-no water consumptive cooling when ambient conditions allow, transitioning to water consumptive methods only when necessary. This flexibility delivers exceptional PUE and WUE performance across a wide operating range.
In Ashburn, Virginia, our facilities that require the use of evaporative water for heat rejection will be served by grey water, a source of wastewater that is lightly treated and not fit for human consumption.
In Milan, Italy, our campus will use non-potable ground water and discharge excess to irrigation channels that serve nearby farmers’ fields, increasing the supply of water to sensitive land uses that would not have it otherwise while also reducing pressure on potable aquifers and overall energy consumption.
Our CDG campus outside of Paris is housed in France, where in 2025, the volume of low-carbon (nuclear and renewable) electricity generated reached an all-time high of 521.1 TWh. This represents 95.2% of the electricity generated in mainland France, demonstrating that our customers can grow responsibly at hyperscale.
Where permitted globally, CloudHQ uses diesel-equivalent, low-carbon Hydrotreated Vegetable Oil (HVO) fuel and advanced after-treatment systems to reduce emissions of our back-up generators.
We are also actively exploring utility-scale batteries as a strategic alternative to diesel backup generators – they deliver greater reliability, lower emissions, and stronger support for long-term resilience and sustainability goals.
CloudHQ’s Green Finance Framework formalizes our commitment to ensuring that the capital we raise directly supports the development and operation of sustainable data center infrastructure. Through Green Finance Instruments – including green bonds, loans, and asset-backed securities – proceeds are allocated exclusively to projects that meet rigorous environmental eligibility criteria.
Concrete production and transportation represent a large source of embodied carbon in construction projects. CloudHQ consistently commissions carbon reduction studies for concrete applications – analyzing mix designs, cement substitutes, and local supply chains early in the design process. Through common analysis in every project, CloudHQ can make material decisions that reduce the carbon footprint of our buildings without compromising structural performance.
