Evaluation of economic approaches under high-end scenarios

IMPRESSIONS WP5 aims to use information gathered in WP1-4 to analyse the synergies and tradeoffs between adaptation and mitigation pathways. The focus is mainly on the level and distribution of societal and economic risks, vulnerabilities, opportunities, costs and benefits within the context of high-end scenarios (HES). This report considers the specific challenges related to appraising policy options under HES. It provides a review of methods for assessing the impacts of adaptation and mitigation pathways, and evaluates the applicability of these methods under the specific context of HES. The report concludes with recommendations for integrating the process of method selection in the IMPRESSIONS workplan, and in particular the stakeholder workshops.
