The UNFCCC will permanently cancel all CDM credits on 25 November 2026. Furthermore, legacy data is scattered across isolated systems with no unified way to consolidate your portfolio, and traditional validation bodies take months to approve simple transfers.
C-AIR provides a single gateway to sync, standardize, and preserve your credits. Our AI-powered framework verifies credit integrity, detects double-spend, and confirms additionality in under 3 days.
Machine learning cross-references your project against global baselines, UNFCCC records, and existing registries to verify environmental integrity and additionality.
