Life Cycle Assessments

Definition

Life cycle assessments (LCAs) are comprehensive evaluations that analyze the environmental impacts of a product or service throughout its entire life cycle, from raw material extraction to production, distribution, use, and disposal. This systematic approach helps businesses identify opportunities to reduce their environmental footprint and make informed decisions for sustainable practices.
