According to the European Green Deal, achieving a decarbonized, prosperous, fair and inclusive European economy by 2050 requires urgently tackling a complex equation encompassing not only economic and environmental challenges, but also social aspects. This entails a strong commitment to ensuring access to clean, affordable and safe energy for all Europeans. Yet millions of European households cannot afford essential energy services needed to guarantee a healthy standard of living. In fact, in 2022, 9.3% of the European population reported being unable to keep their homes adequately warm, a 35% increase from the year before. A series of measures must thus be taken to reverse this situation.
