Green Data Centres Forecast to Hit $160.9 Bn by 2031 on AI‑Driven Energy Efficiency

Why It Matters

The projected $160.87 bn market size underscores how climate‑tech is becoming inseparable from the digital economy. Data centres now account for roughly 1% of global electricity use, and their carbon footprint is set to rise as AI models grow larger. By quantifying the financial scale of green infrastructure, the forecast signals that investors, regulators and corporate buyers will increasingly allocate capital to low‑carbon cooling, renewable integration and digital‑twin design. This shift could accelerate the decarbonization of the broader tech sector and create new revenue streams for firms that master sustainable power architectures. Moreover, the concentration of spending among large enterprises and North American operators suggests that early adopters will set industry standards for energy‑efficiency metrics, water reuse and carbon accounting. As these standards solidify, smaller players and emerging markets may face higher entry barriers, potentially reshaping the competitive landscape and prompting consolidation among technology providers.

Key Takeaways

• Global green data‑centre market projected to reach $160.87 bn by 2031, up from $57.84 bn in 2023.
• Compound annual growth rate of 18.87% for 2026‑2031, driven by AI workloads and stricter emissions targets.
• Solution segment generated $44.59 bn in 2024, representing the largest share of market value.
• Large enterprises accounted for $50.72 bn in 2024 spending, highlighting enterprise‑scale deployment focus.
• North America leads regionally; Equinix and Digital Realty recognized for sustainability leadership.

Pulse Analysis

The green data‑centre forecast marks a watershed for climate‑tech capital, moving the conversation from niche retrofits to core infrastructure investment. Historically, data‑centre sustainability was a cost‑center concern; today, it is a growth engine. The 18.9% CAGR dwarfs the average 5‑7% growth seen in broader IT hardware markets, indicating that sustainability is no longer a compliance add‑on but a market differentiator. Companies like Schneider Electric and ABB are leveraging partnerships with AI leaders to embed digital‑twin tools into the design phase, effectively turning sustainability into a performance metric that can be simulated, optimized and sold to customers.

From a competitive standpoint, the rise of AI‑ready green facilities could accelerate consolidation. Vendors that can bundle power‑management hardware, liquid‑cooling technology and carbon‑tracking software into a single, validated blueprint will likely capture the bulk of enterprise spend. This creates a strategic advantage for firms with deep engineering capabilities and strong OEM relationships, potentially marginalizing pure‑play cooling startups that lack integrated offerings.

Looking ahead, policy will play a pivotal role. As governments tighten data‑centre emissions standards and introduce green‑financing incentives, the cost differential between conventional and sustainable designs will narrow. Companies that have already built a portfolio of certified green projects—such as Equinix, which leverages green financing—will be better positioned to tap emerging funding streams. Investors should watch for a surge in green bonds tied to data‑centre projects and for M&A activity as larger players acquire niche technology firms to close capability gaps. The $160.87 bn horizon is not just a revenue forecast; it is a roadmap for where climate‑tech capital will flow over the next decade.
