Introduction
· Life Cycle Assessment (LCA) is a systematic tool used to evaluate the environmental burdens associated with a product, process, or activity by identifying energy and materials used and wastes released.
· The ISO 14040 series provides the international standard requirements for conducting a high-quality, transparent LCA.

Information Booster
· ISO 14040 is the overarching standard that defines the four essential phases of LCA and ensures the study is scientifically and technically valid.
· The Life Cycle Inventory (LCI) (ISO 14041) is often the most time-consuming phase, as it requires detailed accounting of every "cradle-to-grave" input like raw materials and energy.
· Impact Assessment (ISO 14042) converts inventory data into common units (like CO_2 equivalents) to understand global warming potential or acidification.
· The Interpretation phase (ISO 14043) ensures that the findings are consistent with the initial goal and scope and identifies significant issues.
· In recent years, ISO 14041, 14042, and 14043 have been consolidated into the updated ISO 14044:2006 standard, while ISO 14040 remains the framework guide.

Additional Information
· Interpretation (i): Mentioned in ISO 14043, this is the final check-and-balance phase of the LCA process.
· Impact assessment (ii): Standardized under ISO 14042, it translates technical data into environmental consequences.
· Principles and framework (iii): Governed by ISO 14040, this is the foundational document for any environmental management study.
· Inventory Analysis (iv): Covered by ISO 14041, it is the "accounting" phase of the life cycle.
