What is life cycle assessment in sustainable engineering?

Life cycle assessment (LCA) in sustainable engineering is focused on assessing a product's environmental impacts throughout its entire life cycle. This includes all stages from the extraction of raw materials through production, distribution, use, and disposal. By considering each phase of a product's life, LCA provides a comprehensive view of the environmental consequences associated with it. This approach is essential for identifying areas where improvements can be made to reduce negative impacts, promote sustainability, and inform strategic decision-making in design and production practices.

Unlike the other options, which focus on marketing strategies, costs, or recycling methods in isolation, the concept of LCA examines the broader context of a product's environmental footprint, making it a critical tool in sustainable engineering practices. This holistic view is vital for ensuring that all aspects of a product's life are considered in efforts to minimize harm to the environment.
