Japan is expected to issue data center regulations in 2026: data centers that do not meet a 1.4 PUE limit will face penalties. However, enterprise data centers appear to have evaded the stipulations.
A last-minute revision to the European Commission’s plans to simplify regulations has brought some companies back under the scope for CSRD reporting.
Data4 needed to test how to build and commission liquid-cooled high-capacity racks before offering them to customers. The operator used a proof-of-concept test to develop an industrialized version, which is now in commercial operation.
Competition for grid power is increasing; data center operators need to use reserved grid power responsibly — to support business objectives, maintain strong relationships with authorities and avoid negative publicity.
Enhanced geothermal systems use advanced drilling and hydrofracturing techniques to access geothermal energy in more locations. Some data centers may use enhanced geothermal energy for on-site, low-carbon power.
The European Commission published the final assessment of the data center label and minimum performance standards (MPS) in October. The final delegated act could require posting a label in 2026 or 2027, with MPS values likely to be 2 years away.
The proposed Scope 2 Guidance updates radically alter current accounting methodologies. These changes will complicate Scope 2 offset markets (e.g., EACs, RECs and GOs), adding unnecessary complexity and resource demands to Scope 2 accounting.
The European Parliament plans to simplify environmental reporting beyond what the Omnibus proposed in early 2025. Under the new reporting thresholds, only the largest 10% of companies would remain subject to CSDDD and CSRD requirements.
China wants to expand its data center capacity, and to achieve net-zero emissions. To this end, the nation is regulating for efficiency and renewable energy, as well as harnessing centralized control, to balance growth with sustainability.
Uptime's 2025 cooling survey found that fewer respondents cited sustainability as a primary driver for direct liquid cooling (DLC). Gradual advancement of DLC plans may be refining operator understanding of its incentives.
The public wants to understand data center resource use and performance metrics. Data center operators need to propose a label format that shares appropriate performance metrics while protecting confidential information.
Currently, the most straightforward way to support DLC loads in many data centers is to use existing air-cooling infrastructure combined with air-cooled CDUs.
This report analyzes facility-level PUE data from the Global Data Center Survey 2025, highlighting differences by region, facility size and age. It assesses the vulnerability of the industry to PUE minimum performance standards.
Large-scale AI training is an application of supercomputing. Supercomputing experts at the Yotta 2025 conference agree that operators need to optimize AI training efficiency and develop metrics to account for utilized power.
Fewer people in the industry are talking about sustainability. But why has the collection of data also declined, when such data is often required by reporting regimes?
