Brookfield Infrastructure’s European data centers business, Data4, has continued to improve water efficiency and reduce landfill waste through targeted operational measures.

To limit water use, Data4 does not use cooling towers nor adiabatic cooling systems, which consume high amounts of water. As a result, they achieved a Water Usage Effectiveness (WUE) of 0.04 liters/kWh at the group level in 2025, compared with 0.06 liters/kWh in 2021. In 2026, Data4 plans to further reduce its WUE by using gray water, rainwater or industrial wastewater in its processes.

Data4, under its waste management policy, implemented waste sorting processes increasing the share of waste reused or recycled from 10% to 98% between 2021 and 2025. Data4 also obtained the Green Circle “zero waste to landfill” certification for its data centers in France, Italy, Spain and Poland. It is also engaging suppliers through its sustainable procurement policy.
