Assess learners' ability to apply life cycle assessment (LCA) to compare environmental impacts of single‑use versus reusable foodservice packaging by defining goal and functional unit; selecting system boundaries and end‑of‑life scenarios; compiling life‑cycle inventory (materials, production, transport, use-phase including washing and drying for reusables); choosing relevant impact categories (GHG emissions, energy, water, waste); performing sensitivity and scenario analyses (reuse rate, wash frequency, transport distance); conducting allocation and uncertainty assessments; and interpreting results to make evidence‑based recommendations. Tasks include sample calculations, scenario comparisons, and critical evaluation of assumptions and data quality.
