Case Study: TUV Rheinland achieves tamper-evident carbon credit verification with Focaloid Technologies

TUV Rheinland seals every carbon credit with Focaloid Technologies using RS256 signatures and public verification proofs

Focaloid Technologies partnered with TUV Rheinland, an international testing, inspection, and certification body that validates greenhouse-gas reduction projects and issues carbon credits. The client faced a significant challenge as their manual process, reliant on spreadsheets and emailed PDFs, lacked tamper-evidence, separation of duties, and a way for third parties to independently verify a credit's authenticity without contacting the authority directly.

Focaloid implemented a dual-workflow registry platform that enforces a maker-checker audit lifecycle and cryptographically seals every credit with a signature from a managed key vault. The solution provides public, hash-addressable verification opinions, allowing any third party to confirm a credit's authenticity without an account. This transformed the process from an unverifiable manual system into one with non-repudiable issuance, system-enforced separation of duties, and a consolidated multi-tenant registry, setting targets to reduce verification time and eliminate disputed credits.
