Our guiding principles
Five principles guide ARC and ensure a solution that is practical, inclusive and future-ready.
The system and data belong to the country, permanently.
Configure to fit your regulatory and institutional reality.
Works with existing MRV and climate data systems, not against them.
No vendor lock-in, no donor dependency.
Free in its standard version, with predictable, modest costs for customisation.
ARC, the Adaptable Registry for Carbon, was created by GIZ on behalf of the Team Europe Data Governance in Africa Initiative and technically developed by Verst Carbon.
