Assess learners' ability to apply life-cycle assessment (LCA) methods to compare environmental impacts of single-use versus reusable food packaging in municipal programs. The quiz will test goal and scope definition, selection of functional unit, system boundaries, inventory data needs (materials, production, transport, use/cleaning, end-of-life), choice of impact categories (e.g., GWP, water use, eutrophication), basic calculations or interpretation of LCA results, sensitivity/uncertainty analysis, and translating findings into policy or program recommendations for municipal implementation. Include scenario comparison and justification of assumptions.
