This practical course introduces students to the principles and framework for Life Cycle Assessment (LCA) as guided by the ISO 14040 standard and teaches how to conduct 'dummy' LCAs per ISO 14044 standard's requirements. By being involved in fieldwork and using openly available LCA software and datasets, students will perform dummy LCAs for chosen products and investigate their environmental impacts. By doing so, students apply and solidify their theoretical and practical knowledge about sustainability analytics. They learn the basics of life cycle inventory collection, impact assessment methodologies, hot spot analysis, eco-designing, and eco-optimization basics. Besides, students also learn to write official LCA reports.
