No. The verification and certification processes for RECs and GOs, such as those required by Green-e® or the I-REC Standard, only confirm that two RECs are not registered for a single MWh of generation from a renewable energy generator (i.e., no double issuance).
None of the substantive criteria that are standard for environmental accounting or impact verification in the context of a consequential environmental accounting or GHG emission reduction projects and offset credits occur in the case of REC or GO certifications. For instance, verification of a REC will confirm that 1 MWh was generated from a qualified resource and that the certificate was only claimed once. But, the certification does not provide credible assurance that a certificate meets other environmental integrity principles.
