Validation
Validation is the process of independent evaluation of a A6.4 project activity or PoA by a DOE against the requirements of the A6.4 rules, modalities and procedures and relevant decisions of the Paris Agreement and the Supervisory body (SB), on the basis of the PDD or PoA-DD and CP-DDs.
A validation contract will be signed between CEC and the A6.4 activity participant(s). CEC will start the formal validation process when related application documents (including the PDD) were received. the validation process includes: determine the changes of PDD or PoA-DD, desk review, on-site visit and assessment (if applicable), and completion of draft validation report, internal technical review, completion of final validation report and submission of request for registration to SB. SB will conduct completeness check and substantive check, then register this project as an official A6.4 project if no other issues were identified.

Verification/ Certification
Verification is the periodic independent evaluation and ex post determination by a DOE of monitored GHG emission reductions or net GHG removals that have occurred as a result of the registered A6.4 project activity or PoA. 
Certification is the written assurance by a DOE that, during a specified time period, the A6.4 project activity or PoA achieved the GHG emission reductions or net GHG removals, as verified.
A verification contract will first be signed between CEC and the A6.4 activity participants for the verification/certification process. CEC will start the formal verification process after the related application documents received. The verification process includes: desk review, on-site assessment, completion of draft verification/certification report, internal technical review, competition of final verification/certification report, submission of request for issuance to SB. Then SB will conduct completeness check and substantive check, then issue A6.4ERs  if no other issues were identified.
