Data centre & AIDC

Sustainability due diligence for the AI data-centre era

Singapore’s data centres consume roughly 7% of national electricity, and the government decides who grows. Getting — and keeping — capacity now depends on an ESG scorecard and a credible technical roadmap. CarbonEase Asia brings a Beyond PUE framework and a BESS + CFE accessibility model to developers, REITs and their financiers.

The pressure

Capacity is now conditional on sustainability

Singapore paused new data-centre builds, then reopened them on strict terms: higher efficiency, greener power and reporting. The same logic is spreading across the region.

The compliance shift. Hourly / 24-7 clean-firm-energy (CFE) reporting is becoming the norm, and REC-only procurement is no longer sufficient. The market needs provable green-power provenance, not certificates of intent.
Our framework

Beyond PUE — six dimensions of AIDC sustainability

PUE alone hides the risk. Our due-diligence framework scores a facility across six dimensions and returns a red-flag register, not a scorecard.

Energy

PUE, part-load efficiency, cooling architecture, IT-power density and load profile.

Water

WUE, water-stress exposure, cooling-water sourcing and discharge strategy.

Carbon

CUE trajectory, Scope 1–3 and CFE procurement structure, 24/7 matching.

Materials

Embodied carbon, equipment lifecycle, circularity and e-waste pathways.

Lifecycle

Design-to-decommission assumptions, refit and capacity-expansion scenarios.

Social licence

Community, grid-impact and disclosure posture — the non-technical veto.

PUE ≤ 1.25

WUE ≤ 2.0

Accessibility model

Why Singapore caps at 3–5% CFE without storage

Our APAC BESS + CFE model quantifies a fact most developers only feel: intermittent renewables alone cannot deliver clean-firm energy at the utilisation a data centre needs. Storage changes the answer entirely.

The market

Five unmet needs across the region

Southeast Asia’s data-centre build-out is outrunning the services built to make it defensible.

01

MRV

Measurement, reporting and verification that lenders and regulators can rely on.

02

Scope 3 data

Supplier-level emissions for equipment, construction and logistics.

03

PUE abatement

Quantified, costed efficiency measures — not generic advice.

04

Carbon-tax filing

Exposure modelling and compliance for Singapore and the wider region.

05

Green-power provenance

Hourly, traceable CFE rather than certificate-only claims.
