Rainbow Becomes Ninth Program Approved as CCP-Eligible by Integrity Council

The Integrity Council for the Voluntary Carbon Market has confirmed Rainbow, formerly known as Riverse, as the ninth carbon crediting program to achieve CCP-Eligible status under version 7 or later of its Standard Rules. The France-based program has over 80 registered projects spanning biochar, enhanced rock weathering, and electronic device refurbishment.

Rainbow's CCP-Eligible approval covers Standard Rules v7 or later, which incorporates significant governance and integrity upgrades including clearer roles for governing bodies, tighter validation and verification body accreditation and rotation rules, and stronger additionality and crediting-period requirements. Additional improvements include enhanced reversal risk assessment and buffer pool rules, expanded environmental and social safeguard provisions covering Free Prior and Informed Consent, and greater registry transparency through expanded public disclosure of project documentation and credit status. Rainbow was previously assessed under its former name Riverse using version 5 of its standard and found partially consistent by CORSIA, then reassessed under the ICVCM's non-CORSIA pathway.

As of February 2026, the ICVCM's assessment decisions to date cover nine approved programs: ACR, ART TREES, CAR, Equitable Earth, Gold Standard, Isometric, Puro.Earth, Rainbow, and Verra. The Governing Board has approved 38 methodologies and found 22 did not meet requirements. An estimated 106 million credits have been approved to use the CCP label, with approximately 52 million available in the market. Rainbow's portfolio of over 80 projects — covering methodologies not yet assessed by the ICVCM — will now enter the methodology assessment pipeline under the two-tick process.

Ludovic Chatoux, Co-founder and CEO of Rainbow, stated that the recognition confirms the platform's vision of combining scientific rigour, field engineering, and operational excellence to meet the market's highest integrity standards. ICVCM Board Chair Annette Nazareth highlighted Rainbow's adoption of the CCPs as the global reference point for quality, consistent with the growing list of programs that have strengthened their governance to meet the threshold. Rainbow's inclusion expands the diversity of CCP-eligible approaches in carbon removal, adding novel European-based methodologies to the global high-integrity credit supply pipeline.
