About ACT-ID.io
ACT-ID.io is a project to create and promote standard activity identifiers for sustainable finance — making financed activities easier to identify, compare, and reference across the bond market.
The project
ACT-ID.io was created to address a simple but persistent problem in sustainable finance: the same financed activity gets described in many different ways by different market participants, making comparison, mapping, and data quality unnecessarily difficult.
The project builds a registry of standard activity identifiers — Act IDs — that can be used freely in disclosures, frameworks, SPO opinions, and public reporting. Each Act ID is a stable, hash-derived reference for a specific financed activity, with associated criteria, mappings, and provenance records.
The goal is broad market adoption — not to replace existing language or frameworks, but to add a shared reference layer that makes every participant's work easier to connect with every other participant's work.
Design principles
ACT-ID.io is designed to be:
- Open for public use. Act IDs can be freely referenced in any non-commercial context.
- Market-facing first. The system is designed for adoption by practitioners, not academics.
- Methodologically sound. Activities, criteria, mappings, and provenance are tracked as independent, citable objects.
- Low-friction to adopt. You add an Act ID alongside your existing description — you do not replace it.
- Financially sustainable. A simple vendor licence supports the ongoing maintenance and growth of the registry.
Who is behind it?
ACT-ID.io is an independent project. More information about the team and governance structure will be added here as the project develops.
