Life Cycle Assessment (LCA) is a methodological framework for evaluating the environmental impacts of a product from inception to end-of-life. It involves goal setting, inventory analysis, impact assessment, and interpretation to reduce ecological footprints. Challenges include data quality and methodological choices, while case studies provide practical insights into sustainability.
