Cite activities precisely. See across jurisdictions.

Why regulators and supervisors use ACT-ID

Guidance, consultations, and market monitoring all need to refer to specific financed activities — and those references need to keep working as taxonomies are revised, and be legible to market participants operating under a different jurisdiction's taxonomy entirely. A phrase in a policy document doesn't survive either requirement well; a permanent identifier does.

Jurisdiction-to-jurisdiction comparison

The crosswalks are downloadable comparison tables showing how the same activity is treated across taxonomies — useful when assessing how a proposed rule or threshold compares with peer jurisdictions' existing treatment of the same activity.

Real market documents carrying the IDs

/examples shows real green and sustainability bond frameworks and opinions, tagged with ACT-IDs, so you can see how the identifiers appear in actual market documentation rather than in the abstract.

Open, verifiable data

The full registry is open, CC-BY licensed, and hash-verified — every taxonomy version carries a SHA-256 content hash, and every mapping carries its source document, page, method, and confidence rating. Nothing needs to be taken on trust; it can be checked directly.

A public governance trail

The changelog is a public record of every substantive change to the registry — architecture, schema, and individual identifier decisions — each with a dated rationale. It functions as a governance trail for anyone citing an identifier in official guidance.
