Supporting European and national energy efficiency action with the REFEREE tool

Referee is an online decision-support tool for energy efficiency measures. The European and national tool calculates energy and non-energy impacts of energy efficiency measures at EU and national level based on a predefined set of reference scenarios to be selected by the users.

Everyone can use the Referee tool: no specific sofware or modelling skills are required. Simply enter the policy measures that you are interested in and click on ‘Run’. You will get an overview of the most relevant indicators and will also be able to download a comprehensive in-depth report (excel file) for further analysis.


Click on the green button to run your own policy simulation for European and national energy efficiency measures.
