I am developing a new methodology. What VCS additionality requirements must it meet?

New VCS methodologies must provide a complete method for demonstrating and assessing additionality, based on VCS additionality requirements. A methodology can either reference and explicitly require the use of the CDM Tool for the Assessment and Demonstration of Additionality. Or it can develop its own approaches and tools for demonstrating and assessing additionality.  VCS additionality requirements set out three types of additionality tests (project test, performance test and technology test). These additionality requirements do not constitute a complete additionality tool.
