Sustainability andclimate reporting

For Andria Zou

The negative-grid-impact claim is publishable, not just marketable. NGEP is the framework that makes a 1 MW pod a net-positive site for the host city, and the white paper is the artifact that makes it a recognised category in the NCP rubric.

06 The Thesis
The Equinix-NVIDIA blog of March 2025 is the only public NCP sustainability artifact and it is a 7-minute post, not a framework. The closed-loop, biogas-prime, server-heat-to-digester pattern lives in the silences of that post. NGEP is the metric that makes the silence publishable. San José is the live deployment that produces the data. The white paper is the artifact that makes it the rubric.

The Equinix-NVIDIA blogis the entire public commitment#

The only publicly-indexed NCP sustainability artifact authored by NVIDIA today is a March 2025 blog post. We start there because everything else is white space.

The artifact is a co-authored Equinix blog post of 6 March 2025, written by Tiffany Osias of Equinix xScale and Andria Zou of NVIDIA Global AI DC Strategy. It is seven minutes long. Andria Zou's other public statements on NCP sustainability are LinkedIn posts, Data Center World speaking engagements, and her Equinix author page. No standalone NVIDIA-domain technical paper authored solely by NVIDIA on NCP sustainability has been published.

This is the published commitment surface. It is small. It is also the only thing the rest of the partner ecosystem has to navigate by. The silences in that surface are the topography of the white paper.

What the blog commits to
The published surface
  • PUE 1.30 annual average
  • ASHRAE A1A 27 °C inlet
  • Direct-to-chip liquid cooling at 100 IBX worldwide
  • 96% renewable energy coverage
  • NVLink copper interconnect efficiency
  • GPU efficiency as the unit of progress
What the blog is silent on
Where MicroLink sits
  • Heat recovery to district heating, industrial process loops, or wastewater anaerobic digesters
  • Embodied carbon and circular economy framing
  • WUE target alongside PUE
  • Hydrogen, fuel cells, or biogas as primary power
  • Grid-mix transparency at hourly resolution
  • Negative-grid-impact measurement

The white paper opportunity is additive, not duplicative
San José's design choices map cleanly onto the silent column. The white paper is therefore the first systematic articulation of an NCP sustainability rubric in a single document. Andria Zou as co-author, with the MicroLink CTO and the City of San José sustainability lead. Target publication twelve months after first commercial operation, allowing four full quarters of operational data.

NGEP is the metric thatnames what is not yet named#

No standards body publishes a metric for the case where the host facility's own generation displaces more grid energy than the data centre draws. NGEP is the proposed name and the proposed methodology.

The framework lives in the silences. There is no IEEE, ISO, IEC, FERC, EPRI, LBNL, Uptime, or Green Grid metric for what happens when an industrial host's existing cogeneration is freed by the AI workload's heat return, and the result is a net export of grid-displacing electrons. The vocabulary does not exist because the configuration does not exist at scale.

We propose the name. Net Grid Energy Position.

NGEP = biogas cogen kWh that displaces RWF grid import − data-centre kWh imported from the utility
Metering Revenue-grade accuracy at ANSI C12.20 Class 0.2 or IEC 62053-22 Class 0.2S. Hourly time-matched, annualised reporting.
Boundary Defined per ISO/IEC 30134-1 and ISO/IEC 30134-6. Site-edge as the integration point. Tenant import isolated from cogen export.
Assurance GHG Protocol Scope 2 Quality Criteria against double-counting with RECs or LCFS credits. ISO 14064-3 third-party assurance recommended.

Why NGEP > 0 is a credible claim at this sitespecifically

The San José Regional WWTP runs an existing ~14 MW cogeneration nameplate against a documented ~11 MW plant load. The 1 MW IT pod plus auxiliaries at PUE 1.12 adds ~1.12 MW total facility draw, equivalent to ~9,811 MWh per year. Combined demand stays under cogen capacity. The NGEP > 0 claim is supportable subject to the metering and exclusivity rules above.

Why NGEP needs a sponsor beforeit gets named

A metric without a sponsor is a footnote. The NCP rubric is the only sustainability framework with NVIDIA's name on it that other partners actually consult. Andria Zou is the named owner of the rubric in publicly-traceable form. If NGEP is to become a category alongside PUE, ERE, ERF, and WUE inside that rubric, it has to enter through her.

!
California AB 1305 makes the framework necessary, not optional
If MicroLink markets "negative grid impact" anywhere public-facing, AB 1305 disclosures become mandatory. The Voluntary Carbon Market Disclosures Act requires anyone making net-zero or significant-emissions-reduction claims to publish source-and-methodology disclosures with annual updates, under penalty up to $2,500 per day capped at $500,000. The NGEP framework is the disclosure compliance, not just the marketing claim.

The regulatory laddereveryone else is climbing#

EU EED 2027, the German EnEfG steps, California SB 253 and SB 261, and AB 1305 disclosure liability. The San José design clears the strictest 2028 benchmark from day one.

Disclosure

The ladder structure is the answer to the implicit question every regulator and every reviewer asks: does the claim survive the most demanding active rule? San José's design clears the German 2028 benchmark from day one because the closed thermodynamic loop is engineered, not bolted on. The white paper externalises the proof.

The white paperis the artifact of record#

The framework is the contribution. The site is the proof. The white paper is the artifact every other city reads before commissioning their own.

The audience is not the meeting attendees. It is the next thirty NCP candidates, the EU member-state authorities preparing for EED Article 26 enforcement, and the US municipal CIOs and sustainability directors who will read it before approving anything similar in their own city. The artifact is the carrier that makes San José cloneable.

Distributionwhere the paper lives

Primary distribution on the NVIDIA Technical Blog, cross-posted via nvidianews.nvidia.com. Industry reach via Data Center Dynamics, where Andria's profile already lives. Methodology section to Uptime Institute Journal. Preprint to arXiv under cs.CY plus cs.DC. Co-presentation at NVIDIA GTC, OCP Global Summit, SC, and Data Center World. The negative-grid-impact methodology submitted to ASHRAE TC 9.9 and The Green Grid for inclusion in the xUE family.

Sections 04 and 05 are the Andria sections
The NGEP definition lives in §04. The PUE/ERE/ERF/WUE production data lives in §05. These are the two sections where Andria Zou's name carries the contribution into the NCP sustainability rubric. Everything else in the paper supports those two sections.
