A new approach to assess individual contributions to energy transition goals

This paper introduces an innovative system for quantifying and enhancing individual engagement in sustainable energy consumption behaviours that support the energy transition goals set by the European energy policy. Focusing on residential energy use and transportation, the study proposes an innovative labelling system that monitors and evaluates personal energy habits, linking them to CO 2 emissions and energy demand reductions. The algorithm, developed using publicly available data from reputable sources, is tailored for application across the 27 EU member states and the UK, facilitating meaningful regional comparisons. The paper outlines the design methodology, algorithm development, and insights from a peer review involving 12 international experts, along with feedback from over 1800 users across Europe. By providing an accessible, data-driven framework, this research fosters citizen engagement in the energy transition, contributing to sustainable development goals and advancing global sustainability initiatives. • The study introduces an innovative labelling system designed to quantify individual energy behaviours, integrating residential and transport energy use. • This system is applicable to all 27 EU member states and the UK, enabling regional comparisons and advancing energy citizenship metrics. • Data from 1,800 European users were collected to refine and optimize the algorithm supporting the labelling system. • The study identifies key challenges citizens face when recognising and analysing their energy behaviour patterns.
