Prime Data Centers Matches 100% of Scope 2 Emissions With Clean Energy, But Coverage Sits at 68% Overall

Prime Data Centers' 2026 Sustainability Report states the company matched 100 percent of its Scope 2 greenhouse gas emissions with clean energy sources in 2025, up from roughly 36 percent coverage the prior year, but overall clean energy coverage across its US operating portfolio, once combined with customer procurement, reached 68 percent. The company's Dallas and Sacramento facilities earned ENERGY STAR certification, placing them among the top 25 percent of US data centers for energy efficiency, and Prime purchased water credits equal to 120 percent of its 2025 operating water withdrawals.

 

Why "100% Matched" and "68% Coverage" Are Both True but Describe Different Things

 

The apparent gap between these two headline figures is not a contradiction but a reflection of how Prime's own emissions accounting methodology allocates responsibility for electricity use inside its data centres. Prime's report explains that for its single-tenant data halls, the majority of its facilities, electricity consumed by customer IT equipment and by the cooling systems serving that equipment is categorised as Prime's Scope 3 emissions rather than Scope 2, since customers control server selection, utilisation and operating conditions even though Prime physically operates the cooling infrastructure. Only overhead power, covering offices, lighting and administrative functions, falls under Prime's own Scope 2.

That means Prime's "100% Scope 2 matched" claim applies to a comparatively small slice of the electricity actually consumed within its data centres, the administrative and overhead portion, while the much larger share tied to customer IT load and cooling sits in Scope 3, where clean energy coverage depends on both Prime's and its customers' separate procurement decisions. The blended 68 percent figure reflects that combined picture, giving a more complete but less flattering view of how much of the electricity actually powering Prime's data centres comes from clean sources.

Why the Carbon Intensity Metric Moved in the Wrong Direction

 

Buried within the report's metrics table is a detail that runs counter to the report's generally positive framing: Prime's Carbon Usage Effectiveness, a metric measuring Scope 1 and 2 emissions per unit of customer IT electricity consumption, worsened from 0.109 in 2024 to 0.178 in 2025, and design Power Usage Effectiveness similarly increased from 1.20 to 1.33 over the same period, with a PUE closer to 1.0 indicating greater efficiency. Both metrics moving in the less favourable direction in the same year the company reports achieving 100 percent Scope 2 clean energy matching suggests the portfolio's underlying operational efficiency, independent of the clean energy sourcing question, declined somewhat during 2025, possibly reflecting the mix of newer, less optimised facilities entering the operating portfolio, though the report itself does not explain the specific driver behind this shift.

That distinction matters because clean energy sourcing and operational efficiency are two separate levers, and improving one, matching more electricity consumption with renewable certificates, doesn't necessarily mean the other, how efficiently the underlying facility converts total power into usable IT capacity, is improving in parallel.

 

Why Prime Explicitly Declined to Set Long-Term Emissions Targets

 

Unusually candid for a corporate sustainability report, Prime states directly that despite completing a comprehensive climate risk assessment and decarbonisation roadmap in 2025, "we continue to evaluate which long-term emissions reduction targets would be the most actionable and meaningful for our business at this time," and that it "would be premature to establish long-term targets without a clear and achievable implementation roadmap." That reasoning centres on the company's acknowledgment that meeting rapidly growing AI-driven customer demand may require energy solutions beyond traditional grid electricity, including onsite natural gas generation, a technology path the company states is "not fully aligned with our long-term commitment to decarbonize."

That admission is a genuinely unusual level of transparency in a sustainability report, most companies frame fossil fuel bridge strategies in more favourable terms than an outright acknowledgment of misalignment with their own stated climate commitment, similar to the tension flagged elsewhere in this batch around gas-fired power serving AI infrastructure and grid-balancing roles. Prime's decision to avoid setting a binding long-term target while this tension remains unresolved is a more conservative approach than issuing an ambitious target the company may not have a credible pathway to achieve, though it also means external stakeholders have no fixed benchmark against which to measure the company's future progress.

What the Water and Waste Figures Reveal About Genuine Versus Offset-Based Progress

 

Prime's water strategy relies heavily on non-evaporative closed-loop cooling systems across its portfolio, reporting an extremely low Design Water Usage Effectiveness of 0.001, alongside annually purchasing water credits equal to 120 percent of its operating water withdrawals to fund external watershed restoration projects. That combination, genuine operational water efficiency through closed-loop design, paired with an offset-style credit mechanism for the water still consumed, mirrors the structure of Google's water replenishment programme covered elsewhere in this batch, both companies pairing direct consumption reduction with external replenishment funding rather than relying on either approach alone.

On waste, Prime reported an 88.6 percent construction and demolition waste diversion rate across active US construction sites, but the company was notably candid about a limitation in how that figure is calculated: much of it relies on single-stream recycling, which "can overstate true recycling rates" since materials collected together are sorted off-site and contamination can reduce actual diversion. In response, Prime introduced new contractual requirements for source-separated waste streams in 2025, explicitly acknowledging that resulting diversion rates measured under the new methodology may appear lower than the current single-stream figure despite representing more reliable underlying data, a rare instance of a company flagging that its own improved measurement approach might produce a less impressive-looking number going forward.

 

What the Embodied Carbon and Refrigerant Details Signal About Construction-Phase Emissions

 

Beyond operational emissions, Prime conducted a whole-building life cycle assessment identifying concrete, mechanical and electrical equipment, and steel as its largest embodied carbon contributors, setting a target to reduce embodied carbon in cast-in-place concrete by 20 percent relative to industry benchmarks. That focus on cement specifically, which the report notes accounts for approximately 8 percent of global greenhouse gas emissions, connects to the same low-carbon concrete challenge Neocrete's additive technology targets, covered earlier in this batch, illustrating how data centre construction intersects with the broader industrial decarbonisation challenges facing the cement and concrete sector generally.
