VER project activities. VER project activities must use either an approved UNFCCC CDM methodology or a GS VER methodology to be eligible for Gold Standard registration (see section T.2.2 for applicable methodologies). All project activity documentation submitted to the Gold Standard must apply the most recent version of the selected methodology available at the time of first submission of the project activity for Gold Standard registration. This methodology and version may be used by the project activity until it is registered under the Gold Standard as long as the project activity is submitted for validation within 3 months after the time of first submission for Gold Standard registration.
