Technical report on the integration of sufficiency into scenario models

This report summarises the process of preparing for the integration of sufficiency in energy system models and provides an overview of the existing models in the partner countries, TIMES in Hungary and MESSAGE Lithuania. Analysing the scenario models’ status quo, it aims to provide the first insights for the modelling activities in the project.

The scenario models are also analysed from a sufficiency perspective, identifying the potentials and barriers in the modelling approach. In addition, the impacts of sufficiency and potential outputs of the models are discussed in this report. To make the impacts of sufficiency measures visible in the target countries and initiate a joint dialogue with the policymakers and modellers, the report concludes by analysing the quantitative and qualitative effects of sufficiency and recommending strategies for addressing non-quantifiable impacts.
