IAM_COMPACT_D4.2_From_policy_needs_to_scenario_frameworks_Update

This report is a follow-up to and update of D4.1 (DOI 10.5281/zenodo.10464780); it therefore shares the same approach, by processing the policy needs identified during the realisation of the IAM COMPACT project with the aim of translating them into scenario frameworks. This deliverable also provides a first robust version of the policy catalogue (MS9) in which all 1st PRM cycle policy needs are categorised. It begins with an update of the mapping of modelling capabilities (in the form of heatmaps) carried out by surveying the modelling teams. This information is helpful for associating policy needs and questions to the most suitable models. This is followed by an overview of the modelling work conducted during the 1st PRM cycle—both in setting it up and in the implementation of the studies. It also addresses the new policy needs in the framework of the second modelling cycle, encompassing pending tasks, new policy assumptions and a second package of research questions from policymakers. Finally, all information gathered during D4.1 and this report itself are used to build the policy catalogue in a three-step process: first, a classification of the modelled policies according to their geographical scope and associated policy type and/or instrument; second, a linkage between policy types and the project's set of IAMs; and, third, also based on the literature, a connection between policy types and their impacts on the SDGs, divided into synergies and trade-offs. This analysis has been applied to the policy needs of both the 1st and 2nd PRM cycle.
