Unofficial AI-generated summary based on the public title and abstract. Not an official translation.

🔬研究者:Provides a methodological framework for integrating LCA and MCDA in energy planning, useful for comparative studies.

🏢実務担当者:Offers insights for energy communities and utilities on optimizing renewable systems while considering environmental trade-offs.

🏛政策担当者:Highlights the need for multi-criteria approaches in national energy strategies to balance carbon reduction with resource constraints.

This report investigates the integration of environmental impact assessments into decision-making processes for energy system planning, with a focus on aligning national and community transitions with planetary boundaries. Conducted within the FEDECOM framework, it employs advanced methods, including Life Cycle Assessment (LCA) and Multi-Criteria Decision Analysis (MCDA), to evaluate decarbonization strategies across Switzerland, Spain, and Belgium. The study balances trade-offs between greenhouse gas reductions, material use, and land use, providing actionable insights for sustainable energy development. The EnergyScope model establishes the national context, exploring scenarios for reducing greenhouse gas emissions by 55% to 95%. Results reveal significant differences: Switzerland’s advanced decarbonization highlights challenges in material use, Spain leverages renewable resources while contending with water and mineral depletion, and Belgium’s constrained renewable potential emphasises the need for balanced optimisation. MCDA enables the simultaneous evaluation of multiple criteria such as cost, environmental impact, and resource efficiency. Optimization algorithms, including Genetic Algorithm and Simulated Annealing, identified weight distributions that minimise planetary boundary risks while maintaining economic feasibility. Building on the national framework, the study evaluates energy communities at the pilot scale, including Lugaggia (Switzerland), Ur Beroa (Spain) and Voorhout (Belgium). The findings demonstrate the potential of photovoltaic systems, batteries, and heat pumps to enhance sustainability while addressing trade-offs in mineral depletion and related land use. The MCDA approach ensured these solutions were optimised for both environmental and economic performance, enhancing community self-sufficiency while maintaining alignment with planetary boundaries. The report highlights critical challenges, such as the significant environmental impacts of renewable infrastructure construction, particularly electric vehicle batteries, photovoltaic and biomass production. It identifies these as hotspots requiring targeted mitigation strategies, ranging from improved material efficiency to systemic reductions in consumption. Overall, this deliverable emphasises the importance of integrating multi-criteria approaches into energy planning. By addressing both carbon emissions and broader planetary boundaries, the study provides a robust framework for achieving sustainable and resilient energy systems at national and community levels.
