The video explains life cycle assessment (LCA), a method to evaluate the environmental impact of a product throughout its life cycle. It covers the four stages of LCA: obtaining raw materials, manufacturing, usage, and disposal. The video discusses the environmental consequences of each stage, such as energy consumption and pollution. It also includes a worked example comparing three cars based on CO2 emissions, waste production, water usage, and lifespan, concluding that Car B is the best overall choice despite not being the best in every category.
