ICVCM approves six engineered carbon removal methodologies for CCP-labelled credits

**On October 1, 2025, the ICVCM approved six engineered carbon dioxide removal methodologies and two forestry methodologies to issue Core Carbon Principles-labelled credits. The expanded high-integrity supply gives Indian carbon project developers and corporate buyers a broader, credibility-assured pool of voluntary market credits. **

On October 1, 2025, the Integrity Council for the Voluntary Carbon Market approved six new methodologies for engineered carbon dioxide removal to issue Core Carbon Principles-labelled credits, having previously approved three biochar methodologies in July 2025. The six cover Gold Standard accelerated carbonation of concrete aggregate and five Isometric methods spanning biomass and bio-oil geological storage, subsurface biomass carbon removal, biogenic carbon capture and storage, and direct air capture. The Council also fully approved two forestry methodologies, CAR Mexico Forest Protocol v3 and VM0047 v1.1, for immediate market use, with engineered CDR currently below one percent of issued market volume.

Carbon project developers and integrity-focused buyers globally are affected, with 24 Isometric projects anticipating 3.2 million credits yearly and the Gold Standard methodology expecting over 9,000 yearly credits from 15 registered projects. The CAR Mexico Forest Protocol, under which over 8.1 million credits were already issued, now allows a market leakage rate up to 40 percent and CCP labelling subject to a minimum 40-year permanence commitment. Indian carbon project developers and corporate buyers seeking credible voluntary market credits gain access to a wider range of high-integrity methodologies across removal and forestry categories.

Indian project developers should evaluate which newly approved engineered CDR or forestry methodologies suit their projects, noting that VM0047 v1 has 52 projects in early registration collectively expected to produce 6.5 million credits annually, while v1.1 has 11 projects projected to issue 3 million credits yearly. Corporate buyers should prioritise CCP-labelled credits to ensure integrity. Developers using the CAR Mexico Forest Protocol must meet the minimum 40-year permanence commitment and the specified market leakage rate conditions to qualify for the CCP label.
