All methodologies must include procedures for assessing the additionality of the project interventions. In addition to this, projects must complete a barrier analysis as part of their Project Design Document (PDD). These assessments are reviewed by the Secretariat, Technical Review Panel (TRP), and Validation and Verification Body (VVB) or Independent Expert (IE) (depending on the review process taken) to ensure that they align with the project’s described baseline scenario and project logic, and align with what is visible in the project area.

Additionality must be reassessed by projects every 10 years throughout the project period.

The Standard will adapt and evolve over time to continue to minimise risks to additionality.
