Life cycle assessmentLCA
A methodology for evaluating the environmental impacts of a product, process, or service across its entire life cycle — from raw material extraction to disposal.
Life cycle assessment (LCA) is standardised under ISO 14040 and 14044. It quantifies environmental impacts across multiple categories (global warming potential, acidification, eutrophication, resource depletion) for each life cycle stage: raw material extraction, manufacturing, distribution, use, and end-of-life. LCAs inform product design (design for environment), environmental product declarations (EPDs), and regulatory compliance. In QEHS platforms, LCA data feeds ESG reporting, supplier scorecards, and sustainability disclosures.
