Dr. Jonathan Sanderman

Methodology focus

Senior Scientist at the Woodwell Climate Research Center. Author of the 2022 Science paper calling for regional consistency in agricultural soil-carbon crediting. His 'empty promises' critique of current soil-carbon protocols is the single most cited empirical basis for proof-pack development.

Trellison / LedgerWell intersection. Direct alignment with proof-pack value. High match.

Alignment with proof packs

Their methodology / role	Proof-pack / Trellison fit
Empirical-first methodology	Proof pack centres measurement, not model assumption
Regional consistency requirement	Proof-pack schema enforces region-appropriate calibration
Woodwell institutional strength	Joint Woodwell / Trellison output opens additional funding pathways

Collaboration concepts

Concept 1

Concept 3

Soil carbon data standards workshop

Co-hosted workshop with Woodwell and Colorado State.

Outreach approach

Proposed opening message

Subject: A multi-scale MRV composition engine for your work

Dear Jonathan Sanderman,

Your multi-method MRV framework for nature-based carbon removal has been a design reference for a per-tonne open-data verification instrument that Trellison Institute has been building. We call the artefact a proof pack.

I would welcome a 30-minute conversation to show you the current alpha. We are not asking for endorsement; we are asking for methodology critique and, if useful, an offer of alpha access for your active work. Independent negative evaluations would be published alongside positive ones.

A one-page methodology brief that maps your work to proof-pack schema fields — with gaps flagged honestly — is attached.

With respect,
Rob Stillwell
Director, Trellison Institute

What we do not ask for

Endorsement of Trellison, LedgerWell, DaedArch, or any affiliated entity.
Exclusivity or first-look rights on research findings.
Unpaid labour. Any advisor role is compensated with a modest honorarium and disclosed on the record.
