FAQ

Common questions, clear answers.

Which registries does Tanso integrate with?

We connect to Verra, Gold Standard, ART TREES, Puro.earth, ACR, and CAR. New corridors are added quarterly based on client demand.

How is settlement risk managed?

All transfers are registry-linked with dual approval. We hold no client credits in custody outside official registry accounts, eliminating commingling risk.

Can we use Tanso alongside our existing ETRM?

Yes. We provide REST and FIX APIs and ship native connectors for Allegro, Endur, and SAP. Most integrations go live in under six weeks.

How are credit ratings produced?

Each project is scored against the ICVCM Core Carbon Principles using a blended methodology that combines Sylvera, BeZero, and our internal diligence team.
