The European Commission unveiled a common energy and water rating system for data centers above 500 kW, designed to disclose transparent metrics on energy and water use, waste-heat reuse, and clean energy sourcing, with first sustainability labels due in 2027 as capacity is expected to triple in the coming 5–7 years.

Member states have two months to raise objections; if there are none, the rules will enter into force, paving the way for a Europe-wide labeling framework.

The plan supports Europe’s target to expand data-center capacity to about 28 GW by 2030, linked to AI development and reducing reliance on externally sourced technology, while addressing resource and grid pressures.

Policy developments, corporate sustainability efforts, and investments in decarbonisation and resilience span energy, water, procurement, and carbon markets, illustrating a broad sustainability push.

For operators and investors, the labels would serve as a benchmark to compare facilities, potentially shaping site selection, financing, and interactions with local authorities, and informing future costs and compliance risk.

Locally, the practical impact includes waste-heat reuse to help meet heating needs for millions of households and greater disclosure that lets residents and officials assess nearby data-center water use.

The framework emphasizes transparency over caps, requiring efficiency metrics and disclosures on water stress and interactions with local energy systems, rather than total consumption.

In essence, the labeling seeks to raise transparency about efficiency and contextual factors without mandating total energy or water use limits at this stage.

Brazilian carbon removal startup Mombak signed a multi-year deal with Salesforce to sell credits, joining other buyers like Google and Microsoft, as part of growing corporate investment in nature-based and tech-enabled decarbonisation.

The label’s purpose is to enable comparisons across facilities based on resource efficiency per computing activity and design, not solely on total power use, reflecting cooling, climate, and energy-source differences.

The scheme aims to enable regional comparisons, drive better design and efficiency, reduce energy and water use, promote low-emission energy, and support heat-recovery in nearby systems, with potential gains shown in improved PUE and WUE metrics.

Mandatory metrics include total energy and water consumption, PUE, WUE, share of renewable energy, and confirmation of waste-heat reuse.
