Validation for large-scale projects is defined in 3/CMP.1, Annex, paragraph 35.
3/CMP.1, Annex, paragraph 37 sets out the requirements for validation. The additionality requirement was further clarified by the Executive Board in EB 11, Annex 6 and EB 24, paragraph 79, and the requirements for host Party letters of approval were clarified at EB 8, Annex 3, paragraph 2(a).
Note: Whilst EB 54, Annex 28 has replaced EB 11, Annex 6 and EB 8, Annex 3, the previous procedures remain informative and may provide guidance where the new procedures are otherwise silent.
Additional validation requirements apply where project proponents intend to use a new or revised baseline and monitoring methodology: 3/CMP.1, Annex, paragraph 38-39.
The validation process was confirmed by the Executive Board at EB 13, paragraph 39.
Requirements for validation and verification reports are set out in the Validation and Verification Manual (VVM) (EB 55, Annex 1).
