Commitment Debt Audit

Model

Commitment debt behaves like carbon debt: the balance grows, interest accrues, and a new note is written before payment day arrives. The difference is that carbon debt has a physical counterparty — the atmosphere — while commitment debt has a diffuse one, the public whose attention shifts to the next pledge. The audit forces four items into the same document: the pledge, its baseline, its revision rule, and the party entitled to enforce it. A pledge that lacks any of the four is not a target; it is a headline.

Components

1. Component 1

   The Pledge Stock

   All outstanding commitments made by the entity — net-zero, 2030 target, nature-positive, resource-reduction — enumerated as a single list rather than a rolling narrative.

2. Component 2

   The Baseline

   The explicit reference year, scope boundary, and measurement standard against which the pledge is evaluated. A drifting baseline is a debt restructuring, not a target.

3. Component 3

   The Revision Rule

   The pre-committed protocol for revising the pledge — interim milestones, escalation triggers, and the criteria that would count as a miss. Without this, a miss is absorbed as narrative.

4. Component 4

   The Counterparty

   The party entitled to enforce the pledge — regulator, standard-setter, board committee, independent auditor. If no counterparty exists, the pledge is denominated in reputation, not accountability.

Use cases

• COP outcome reviews across cycles rather than within a single summit.
• Corporate net-zero disclosure design that closes the audit gap between pledge and capex.
• Sovereign NDC updates evaluated as a debt schedule, not a fresh announcement.
• ESG fund methodology reviews focused on additionality and verification, not label count.
