RE-BD AR2024, the 2024 Assessment Report on Renewable Energy and Biodiversity, addresses the critical balance between expanding renewable energy (RE) and better protecting biodiversity in Switzerland, with a special focus on the Alpine regions. It is the result of the project “Towards new renewable energy developments in Switzerland that preserve biodiversity”, supported by CLIMACT, the Center for Climate Impact and Action of UNIL & EPFL, conducted between June 2023 and September 2024. The project reviewed published scientific literature in order to define the conditions needed to reach three key societal goals: climate action, energy security, and ecological integrity. It unites experts in RE, climate, and biodiversity from diverse scientific bodies and universities across Switzerland, aiming to foster mutual understanding and collaboration to achieve the outlined societal goals.
