What additionality test should be applied when using a CDM methodology?
If the project uses a CDM methodology, it must adhere to the specifications of the methodology which may, for example, require use of the Tool for demonstration and assessment of additionality or the Combined tool to identify the baseline scenario and demonstration of additionality. If the Project Proponent wants instead to use an alternative approved additionality tool (e.g., a tool approved by under the VCS Program or CDM), it must document this as a Methodology Revision and have the Methodology Revision approved under the VCS Double Approval Process. Likewise, if the Project Proponent wants to propose directly in the methodology an alternative approach for the demonstration of additionality based on the VCS additionality guidance outlined in Section 5.8 of the VCS 2007.1 document, it must document this as a Methodology Revision and have the Methodology Revision approved under the VCS Double Approval Process.
