REGISTRY

A Trusted and Transparent GHG Registry

ACR established the world’s first carbon registry in 1996 and has been a global leader ever since. We operate a robust, secure and fully transparent registry system with reduction and removals projects to record the issuance, transfer and retirement of serialized, independently verified carbon credits.

About the ACR Registry

The contracting of credits for purchase or retirement takes place directly between buyer and seller through over-the-counter (OTC) transactions outside of the ACR Registry system or on an approved, linked exchange platform. After a transaction takes place, the counterparties record the transfer of ownership or retirement of credits on the ACR Registry.
