As Europe seeks to enhance its competitiveness and resilience while addressing climate and social goals, a transformative approach to energy has become more urgent than ever.
This white paper introduces Energy System Efficiency (ESE) as a critical pillar for ensuring energy security, affordability, and decarbonisation. A holistic focus on ESE will allow Europe to boost its industrial competitiveness, strengthen energy security, and lead the global effort against climate change.
Achieving Europe’s energy transition will require cooperation across sectors. Policymakers, industries, and civil society must collaborate to align legislation, investment strategies, technologies, infrastructure, and practices that will drive the future energy system. By adopting and implementing Energy System Efficiency, Europe can secure a sustainable, competitive, and carbon-neutral future by 2050, ensuring stronger energy security and a higher quality of life for all.
In a fast-changing political and economic environment, 2025 was a year of continued efforts to strengthen security, stability, and competitiveness for European businesses.
Throughout the year, our work demonstrated that energy efficiency is not only essential to achieving climate goals, but also a key driver of innovation, energy independence and sustainable long-term growth across Europe.
Strong engagement with policymakers, combined with the successful organisation of the 4th European Energy Efficiency Day, highlighted the importance of collaboration and dialogue in advancing shared objectives. Partnerships across sectors and institutions remained central to delivering impact and shaping effective energy policies.
Looking ahead to 2026, we will intensify our efforts to secure the regulatory certainty that can accelerate the energy transition, while providing businesses with the investment confidence they need and strengthening Europe’s competitiveness.
