The European Commission unveiled a common energy and water rating system for data centers above 500 kW, focusing on transparency of energy and water use, with waste-heat reuse and clean energy considerations recognized, and first sustainability labels expected in 2027 as data-center capacity is projected to triple in 5–7 years.

Member states have two months to raise objections; in the absence of objections, the rules will enter into force.

The plan supports Europe’s goal to expand data-center capacity to 28 GW by 2030, tied to AI development and reducing reliance on non‑EU tech, while addressing resource and grid pressures.

For operators and investors, the labels will provide a benchmark for comparing facilities, potentially shaping site selection, financing, and relations with local authorities, as well as informing future costs and compliance risk.

The brief highlights ongoing policy developments, corporate sustainability initiatives, and investment in decarbonisation and resilience across energy, water, procurement, and carbon markets.

Locally, the impact is tangible: waste-heat reuse could meet heating needs for about 4 million households, and disclosure will help residents and officials assess nearby facilities’ water use.

Brazilian carbon-removal startup Mombak signed a multiyear deal with Salesforce to sell credits, joining buyers like McLaren Racing, Google, and Microsoft, as Amazon Reforestation Fund II aims to raise $150 million after its $120 million first fund, with 15 million native trees planted across 15 Amazon farms.

The framework emphasizes transparency over hard caps, requiring efficiency metrics and water-stress disclosures, plus information on interactions with local energy systems and grid services rather than total power consumption.

In short, the labeling system seeks to boost transparency on efficiency while not setting total energy or water-use limits.

The label’s purpose is to enable facility comparisons by assessing resource efficiency relative to computing activity and design, reflecting cooling, climate, and energy-source differences rather than just total consumption.

Development of the rating scheme included broad stakeholder engagement in 2025–2026, with a aim to harmonize standards across Member States and reduce regulatory fragmentation.

The scheme aims to drive better design and efficiency, reduce energy and water use, promote low-emission energy, enhance grid efficiency, and enable nearby waste-heat reuse, with expected gains such as PUE from 1.6 to 1.2 and WUE from 1.0 to 0.5.
