This paper offers a structured approach to making these decisions on which mitigation actions are reported as NAMAs (Nationally Appropriate Mitigation Actions) and which of the emerging categories of NAMAs they are assigned to. Building on the review of climate negotiations, and national policies in developing countries along with stakeholder consultations, it develops an approach arranging a range of criteria clubbed under key desirable outcome clusters. Recognising that each criterion within an outcome cluster may have different significance for a country, and scoring against a criterion may involve multiple options, towards which countries may have different positions, the approach allows individual countries to reflect their weighting for each criterion within an outcome cluster and attitudes towards various options for a criterion. Accordingly, each outcome cluster gets positive and negative scores depending upon the specific project details.
