NAVIGATE Project: Report on the workshop “Robustness and legitimacy of models for climate policy assessment”
The first NAVIGATE stakeholder and expert workshop on “Robustness and legitimacy of models for climate policy assessment” took place online on 26-27 May 2020.
European Union’s Horizon 2020 project NAVIGATE aims to develop the next generation of IAMs, and includes a series of activities to create and sustain a continuous stakeholder exchange between NAVIGATE and the key groups of experts and stakeholders, in order to gather feedback on the design of the project’s research activities, the choice of the stakeholder-relevant IAM outputs and policy-relevant scenarios, and on the documentation needs of the stakeholders.
This report presents the outcomes of the Workshop. Robustness refers to the analytical and technical adequacy of the models as well as the validity of modeling results given deep uncertainties and limits to state-of-the-art knowledge. Legitimacy encompasses transparency, traceability and accessibility of the modeling itself as well as the design of participatory processes at the modeling-policy interface. Although often discussed in the last decade, robustness and legitimacy of models face new challenges today because, as in the case of NAVIGATE, the models need to account for increasingly richer structural, regional and distributional information as well as for transformative change in social, technological and economic systems.
