Dr. Noah J. Planavsky

Professor of Geology & Geophysics, Yale University; Scientific Leadership Team, Yale Center for Natural Carbon Capture; co-founder, CREW Carbon; scientific advisor to Verra and Ceezer; Senior Contributing Scientist at EDF and Cascade Climate. The single highest-leverage first contact in the Trellison carbon capture portfolio.

Who he is

Noah J. Planavsky is a Professor of Geology and Geophysics at Yale University's Department of Earth & Planetary Sciences, and a member of the Scientific Leadership Team of the Yale Center for Natural Carbon Capture. He co-founded CREW Carbon, a Yale spin-out that pairs enhanced mineral weathering with wastewater treatment, and serves as a scientific advisor to Verra (the world's largest carbon-credit registry), Ceezer (a carbon-credit platform), the Environmental Defense Fund, and Cascade Climate.

No other individual in the Trellison carbon capture portfolio sits at as many boundary points between academic research, commercial deployment, registry governance, NGO policy, and philanthropic funding. That is why he is the single highest-leverage first contact on the list.

Planavsky is a Packard Fellow, was part of the Yale-led team that received a $5M US DOE grant for enhanced mineral weathering and ocean alkalinity enhancement modelling, and is a recipient of Bezos Earth Fund support for AI-enabled MRV of geochemical carbon dioxide removal. He is also a frequent co-author with Christopher T. Reinhard (Georgia Tech), David Beerling (Sheffield), and the Hartmann / Renforth enhanced-weathering research community.

Selected publications

Selection through April 2026. Weighted toward the CDR-MRV and enhanced-weathering track relevant to proof-pack alignment.

Five networks unlocked from one conversation

Engaging Planavsky opens downstream conversations with multiple institutions where he already holds a seat:

  1. Yale Center for Natural Carbon Capture (YCNCC) — steering committee. Host for joint research fellowships and the Bezos Earth Fund AI-MRV programme.
  2. Verra — scientific advisor. The standing to propose proof-pack schemas as a methodology enhancement to Verra registry practice is non-trivial and only available through someone inside.
  3. Ceezer — scientific advisor. A commercial carbon-credit platform that could be a first integration target for proof-pack-verified tonnes.
  4. Environmental Defense Fund (EDF) — Senior Contributing Scientist. Bridge into US federal policy dialogue on CDR integrity.
  5. Cascade Climate — Senior Contributing Scientist. A non-profit host for a joint Proof Pack research fellowship (Reinhard is also here).
Why this matters: Planavsky is both a scientific advisor to Verra and a co-author of a public paper arguing for reforms Verra has historically resisted. He is inside the tent and on the record about change. Proof packs offer him an operational instrument for the reform he has already argued for.

Alignment with Trellison / LedgerWell work

The paper prescribes a set of transparency properties. The proof-pack schema and the LedgerWell verification stack are engineered to produce exactly those properties. We map:

Reinhard & Planavsky 2026 prescriptionProof-pack / LedgerWell implementation
Open data on CDR methodologiesMethodology attestation record (per-tonne, source-traceable, signed)
Open data on dollar-per-ton costsCost decomposition schema: capex / opex / energy source + carbon intensity / feedstock / logistics / MRV cost
Standardised MRV protocols (cross-methodology comparable)CVR framework — a methodology-neutral verification schema that maps onto ERW, DAC, OAE, soil, biochar
Counter to mitigation deterrenceHonest cost + scale reporting surfaces the gap between CDR claims and mitigation need; proof packs make the gap legible
Co-benefit quantificationProof-pack co-benefit ledger: soil health, water quality, yield, biodiversity, community outcomes
Independent verification pathwaysProof-pack audit chain with third-party attestation hooks and replication packages
Policy / regulatory openness mandates (Verra, ICVCM, SBTi, CRCF)Proof pack as an interoperability substrate: CCP labelling, VCMI claim codes, CRCF attestation mapping

Co-authorship opportunities

The same five co-authorship concepts detailed on Reinhard's profile apply — Planavsky is a first-named candidate on papers 1, 4, and 5. Two additional concepts are stronger with Planavsky specifically because of his Verra advisory standing and CREW wastewater focus:

Paper A

Proof-pack integration with the Verra registry: an interoperability specification

Leverages Planavsky's scientific advisory role with Verra. Specifies how per-tonne proof packs interoperate with VCS (Verra's VM standards), VCU issuance metadata, and the ICVCM Core Carbon Principles labelling. Target: ICVCM or Verra white paper, or a commentary in Nature Climate Change.

Candidate co-authors: N. J. Planavsky, R. Stillwell, Verra standards counterparts

Paper B

Wastewater-integrated enhanced weathering under radical transparency: the CREW Carbon case

Field-scale proof-pack deployment at a CREW Carbon site. Documents the wastewater-ERW workflow end-to-end: mineral input, flow monitoring, alkalinity measurement, ocean-export accounting, cost decomposition, co-benefits (nutrient removal, pH control). Target: Environmental Science & Technology.

Candidate co-authors: N. J. Planavsky, CREW Carbon technical leads, Trellison data team, potentially Hartmann

Paper C

AI-MRV for geochemical CDR: an open-data benchmark

Operationalises the Bezos Earth Fund AI-MRV grant thesis with a shared open-data benchmark hosted on proof-pack infrastructure. Bridges YCNCC's ML modelling with Trellison's data-layer. Target: Nature Sustainability or Nature Climate Change.

Candidate co-authors: N. J. Planavsky, YCNCC AI-MRV team, Trellison, independent benchmarkers

See also Reinhard's profile for papers 1 – 5 (jointly applicable).

Co-sponsorship and sponsored-by opportunities

Co-sponsorship with programmes where Planavsky is already the PI or co-PI

Sponsored-by: funders with stated open-MRV alignment

Outreach approach

Why Planavsky first

He sits at more boundary points (Verra advisor, Ceezer advisor, EDF Senior Contributing Scientist, Cascade Climate, YCNCC steering committee) than any other researcher on our roster. His advisory role with Verra gives him standing to propose proof-pack schemas as registry-methodology enhancements — standing that cannot be acquired from outside.

Proposed opening message (template)

Subject: A reference implementation for the radical-transparency agenda

Dr. Planavsky,

Your January 2026 npj Climate Action paper with Dr. Reinhard landed with
us as a design specification rather than an opinion piece. At Trellison
Institute we have been building a per-tonne open-data verification
instrument — we call the artefact a "proof pack" — that tries to
implement the framework you argue for: methodology attestation,
dollar-per-ton cost decomposition, co-benefit ledger, independent-audit
hooks.

We would welcome a 30-minute conversation to show you the current alpha.
We're not asking for endorsement; we're asking for methodology critique
and, if it's useful to you, offering alpha access tied to a CREW Carbon
deployment. Independent negative evaluations would be published alongside
positive ones.

A one-page methodology brief that maps your paper's prescriptions to
proof-pack schema fields — with the gaps flagged honestly — is attached.

With respect,
Rob Stillwell
Director, Trellison Institute

Leave-behind artefact

A one-page Trellison methodology brief that maps each paper prescription to a proof-pack field and explicitly flags the gaps — where the current implementation falls short of the paper's ambition. Honesty about the gaps is the reputational asset.

Follow-on sequence

  1. If the first call is productive: introduce Reinhard via the Cascade Climate or shared-co-author vector.
  2. Offer a Cascade-hosted joint workshop on proof-pack schema + Verra interoperability.
  3. Draft paper 1 (reference implementation) with Planavsky + Reinhard as co-authors.
  4. Use the published paper as the academic affiliation that reframes every downstream conversation on our Tier 1 / Tier 3 / Tier 4 outreach list.
