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, powered by APX, to register carbon emission reduction and removals projects and to record the issuance, transfer and retirement of serialized, project-based and 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.

Public reports

The use of a fully transparent registry system is fundamental to carbon market credibility. We ensure transparency by requiring that project registration and verification documents be made public. We ensure no double counting or double selling by serializing carbon credits and by linking to online credit issuance and retirement logs.

Opening an ACR
Registry Account

All project developers, validation/verification bodies (VVBs), traders, and retailers must have an ACR account. The process for opening an ACR account is initiated online, with supplemental documentation submitted via email. Each organization that applies for an account will create a single Account Manager login, which will be activated if the application is approved by the ACR Administrator. The named Account Manager will then be able to create additional logins for other account users as needed.

ACR charges account and transaction fees

The steps involved in the Account Opening process are listed below. You can find all the ACR Registry account documents and the application forms within the steps below.

You will be presented with an online Account Information screen. You must complete all required fields, which are noted by an asterisk (*). The email address entered for the Account Manager must be their own direct email address; group email addresses cannot be used. When complete, click “Submit.”

Note: The organization’s name, account type, city/state/country and website are publicly available after approval unless you mark the account as a Private Account. The Account Manager’s contact information will also be available to other current ACR Account Holders only unless you mark the account as a Private Account.

Upon submitting the Account Information form, the Account Manager will receive a New Account Request email. The Account Manager must validate the new account application profile using the unique link contained in the automatically generated email and the newly established login credentials.

This appears as the next screen after clicking “Activate”. Acceptance of the Terms of Use must be done by the authorized Account Manager, identified in step 1 above. The Account Manager must review all terms, checking the box for each section, and agree to the Terms of Use on behalf of the Applicant Organization by typing their full name and title (this serves as their electronic signature) and pressing the “I Agree” button.

Note: Do not use your browser’s “Back” button to view a previous screen during this process or information you enter may be lost.
