En ce qui concerne le Green Deal pour l’UE, la rénovation est prioritaire car la plupart des bâtiments existants seront encore utilisés dans des décennies. Les solutions Reynaers Aluminium peuvent vous aider à réduire l’impact carbone opérationnel de votre projet, grâce à des niveaux supérieurs d’isolation thermique et d’étanchéité à l’air. ## What is the EU Green Deal? The EU Green Deal is the European Union’s strategy to make Europe climate-neutral by 2050. The framework aims to reduce greenhouse gas emissions, boost clean energy, and promote circular economy principles across industries, including the construction sector. To reduce the environmental footprint of buildings, there are two revolutionary waves ongoing. Circularity is one major topic, the other priority is **Energy Efficiency & Renovation**. 75% of European buildings are not energy efficient. We need to focus on reducing their operational carbon – which still account for 70% of a building’s total emissions. - By 2030, 100% of new constructions should have operational carbon levels close to zero. - By 2030, 80% of existing energy-inefficient buildings should be renovated with an aim to cut their operational carbon levels by 50%, compared to 1990 figures. ![Deux installers de Reynaers Aluminium démontent d’anciennes fenêtres sur place.](/sites/default/files/public/styles/image_max_width/public/2025-05/reynaers-aluminium-lifecycle-2.jpg?itok=7WfxEY1H) ![Femme entrant dans la villa moderne par des portes coulissantes dorées.](/sites/default/files/public/styles/image_max_width/public/2025-05/reynaers-aluminium-product-masterpatio_0.jpg?itok=m7Ll0LHI) ## How can we help?
