Verification Process

PDF Print Email


Consistency Applications and Monitoring and Verification Reports must include a signed verification statement and verification report from a state-accredited independent verifier. 

State Accreditation

Each independent verifier must be accredited by the RGGI State in which the offset project is located, although a RGGI State may acknowledge accreditation by another RGGI State.

Pre-Engagement COI Filing

Prior to engaging with an offset project sponsor to provide verification services, an accredited verifier must submit a pre-engagement conflict of interest (COI) disclosure filing to the appropriate regulatory agency in the state where the offset project is located.  This filing is required for disclosure of potential relationships or other issues that could lead to a COI situation between the verifier and the offset project sponsor or a related party.

The links below lead to each state's offset program webpage, which contain state-specific verifier accreditation instructions, verifier accreditation application materials, and pre-engagement COI submittal forms.

Project sponsors should contact state offset program staff with specific program questions. Contact information can be found through the link on the right hand side of this page.
