Scheme Evaluation
GRESB’s accepted assurance and verification standards, as well as criteria for accepted standards, are aligned with the Carbon Disclosure Project (CDP).
Scheme Recognition Criteria
The six criteria for a third-party assurance/verification scheme to be recognized by GRESB are defined as follows:
Relevance: The standard must relate to a third-party audit or verification process. For a program-related standard, the 3rd party verification should be specified as part of the program compliance.
Competency: The standard should include a statement about the competency of verifiers. Where a program and verification parties are stipulated, competency is assumed to be determined by the second party and need not be explicitly stated in the standard.
Independence: the standard must ensure impartiality when the same external organization compiles and verifies a reporting company’s inventory.
Terminology: The standard should specify the meaning of any terms used to describe the level of assurance (e.g., limited assurance, reasonable assurance).
Methodology: The standard should describe a methodology for verifying the process and/or system controls and the associated data.
Availability: the standard should be available for scrutiny.
Additional schemes may also receive recognition if they meet GRESB’s criteria. To submit a new scheme for review, please contact the GRESB team. The final deadline for submitting a new assurance/verification scheme for review by the GRESB team is March 15. Schemes submitted for review after March 15th will not be reviewed until the subsequent reporting year.
