Claims are not evidence.
The Verifiable turns complex sustainability claims into clear, credible, traceable reporting, so readers can tell what is real, what is measurable, and what is worth trusting.
Every claim carries its level of support.
We classify each finding against a five-tier evidence system, so the distinction between what is measured, what is verified, and what is mapped never disappears into the body copy.
Activity logs, internal program outputs, volunteer counts. Useful for scope and context. Does not independently verify outcomes.
Verified by a named partner organization or co-reporting entity. Stronger than self-report. Credibility depends on the partner’s own evidence standards.
Claim is attached to a cited dataset, peer-reviewed study, or lab report. The underlying source can be checked independently.
Third-party review or assurance exists — but with disclosed scope boundaries. The limits of what was reviewed are stated.
Aligned to a standard (GRI, ESRS, ISSB) with explicit boundary language. Framework alignment is named, not assumed.
Three running investigations.
Each series is a sustained inquiry into a dimension of sustainability where the evidence is thin, contested, or miscategorized.

Curious skeptics
Anyone who reads a sustainability report and wonders: how much of this is actually measurable?
What you can expect from every issue.
Every claim names its level of support.
We use the five-tier evidence system on every article, so you always know how strongly a finding is backed.
Sources are cited, not summarized.
Primary documents, peer-reviewed papers, and regulatory texts — linked in full, so you can verify independently.
Limitations are stated, not buried.
Where evidence is thin, contested, or context-dependent, we say so explicitly. No false precision.
Evidence that changes how you read a claim.
New issues on sustainability, climate, and reporting discipline — delivered when they are ready, never on a schedule that dilutes the work.
