Certifications and Labels

The OCP partners with several organizations to allow Project Developers to seek additional certifications and eligibility designations for their projects and credits.

All another certifications and eligibilities are additional designations on top of standard OCP credit issuance. All standard OCP requirements, including third-party validation and verification, permanence and buffer pool obligations, and no double-counting rules, continue to apply in full.

Label or Certification	Label Applied To	Managing Organization	Current Status

CORSIA-Eligible	Credit Issuances	International Civil Aviation Organization (ICAO)	Assessment in Progress (March 2026 - current)

Want to apply another certification, label or framework to your OCP projects and credits? Get in touch with the OCP team to discuss next steps.

Project Ratings

We have relationships with all the major carbon credit rating agencies and provide input to them as part of specific project rating assessments. Project developers, or their investors or buyers, can ask for introductions to the relevant rating teams, but the assessment process (and associated costs) will be run independently of the OCP.

We are in discussions to show project ratings on the OCP Registry.
