Outreach approach

Proposed opening message

Subject: A verification substrate for engineered-CDR claims

Dear Howard Herzog,

Your work on engineered carbon removal has defined the technical bar for what a credible claim looks like. At Trellison Institute we have been building a per-tonne open-data verification instrument — the proof pack — that aims to make your integrity criteria legible at market scale.

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
