Abstract

This report presents a new tool for downscaling outputs from Integrated Assessment Models (IAMs) from model-native regions to the country level. The algorithm produces a range of pathways consistent with the underlying IAM-results, based on a range of criteria. Criteria used for the downscaling include historical data, planned capacities, country-available resource in the form of supply cost-curves, quality of governance as well as regional benchmarks based on IAM results. The tool can be used to explore the implications of Paris Agreement compatible pathways for energy systems and CO2 emissions at the country level and to enhance the regional comparison of IAMs. Finally, results could be used as inputs to other models, to provide national level information consistent with global IAM results.
