Lifecycle assessment

Definition

Lifecycle assessment (LCA) is a systematic process for evaluating the environmental impacts of a product or system from its initial raw material extraction through to its end-of-life disposal. This assessment considers all stages of a product's lifecycle, including manufacturing, transportation, use, and recycling or disposal, allowing for a comprehensive understanding of its overall environmental footprint.
