Aggregating the Impacts of Non-State and Subnational Climate Actions: An Exploration of Methods An Accompaniment to the ICAT Non-State and Subnational Action Guide
The Initiative for Climate Action Transparency (ICAT) has prepared an assessment guide called the ICAT Non-State and Subnational Action (NSA) Guide (ICAT NSA guide) for aggregating the ex-ante GHG emissions impact of non-state and subnational climate actions, but variations in assumptions and methodology still occur in practice. This makes it difficult to communicate and interpret the results of individual assessments and determine the extent to which the results may be comparable.
