Same Borrower, Different Numbers

to make those numbers comparable and auditable across institutions.
Why this table, and why now
In 2026, climate risk moved from disclosure into prudential supervision. Banks must now carry it inside credit, capital and stress testing, and supervisors have begun to enforce it. Yet the same borrower still walks into the market with several different climate-risk numbers: different models, different proxies, different vintages, and few that survive questioning about how they were derived. The result is trillions in exposure priced on data that cannot be compared across institutions, and a supervisory system asked to compare portfolios that do not, in fact, compare. The same weakness runs through fossil fuels, mining and minerals.
The collapse of the voluntary bank climate alliances in 2025 settled one question: self-certification is not a substitute for interoperable, auditable standards. What remains open is what those standards should say, who should shape them, and where the first narrow, practical pilot should sit. That is the conversation this table exists to have.
Why this room can have it
Most institutions cannot discuss shared definitions with their competitors, for good legal reasons. This table can, because it is convened under The Open Group — the standards body behind TOGAF, OSDU and Open Footprint — pre-approved by both the SEC and the EU to operate on an assumed pre-competitive basis. That standing is what allows firms that compete fiercely in every other setting to sit together and agree what certain definitions need to be, for the benefit of all of them.
The Open Group has done this in sectors as demanding as military aviation, healthcare and energy; ODCF applies that machinery to climate finance: a comparability and audit standard that sits across the models each institution already uses. It is not a data provider, not a climate score, and not a rival to the data utilities. No participant will be asked to surrender models, feeds or their own view of a borrower.
What the session is
A closed-door, off-the-record working conversation during Climate Week NYC. There is no panel, no pitch and no press. Ninety minutes, a small table, two questions worth the time of the people around it: what does genuinely comparable, provable climate and finance data make possible in what gets financed, insured and supervised — and what still stands in the way.
A likely first pilot, deliberately narrow, would make counterparty transition-plan data and the inputs to climate stress tests comparable and auditable across participating institutions. The table will pressure-test whether that is the right starting point, or propose a better one.
“We are not selling a product. We are convening the people who can decide whether this is the right thing to do — and how to start.”
Who is at the table
A small group of senior practitioners who make and use these decisions — people who can make things happen, in a room convened to make things happen. Drawn from:
- Banks
- Investors and asset managers
- Insurers
- Supervisors and regulators
- Industry associations
