This paper discusses methodological assumptions to estimate the collective impact of mitigation commitments and targets of non-state and subnational entities. It serves as a supplement to the ICAT Non-State and Subnational Action Methodology. The paper will facilitate users in employing methods that are suitable for their specific objectives when determining the collective impact of mitigation actions taken by cities, businesses and states. It will also promote greater transparency in reporting impact assessment results.
