The Urban Waste Water Treatment Directive to fully realise water and energy savings (updated)
Overall, the Urban Waste Water Treatment Directive (UWWTD) has played a substantial role in improving the quality of European water resources and reducing pollution levels in water bodies. However, Europe remains some way from full compliance with collection and treatment requirements and has made little progress with water reuse. We believe the 28-year-old Directive should be updated to better address these critical issues and today’s challenges including climate change, resource scarcity, increased energy consumption and population growth.
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.
