Life Cycle Inventory (LCI) Data and Environmental Metrics

Increased environmental awareness in recent years, driven by regulatory and market demands for improved environmental performance, has given rise to the importance of life cycle assessment (LCA) as a decision-making tool.

LCA provides a systematic framework to compile and evaluate the inputs, outputs and potential environmental impacts of a product system throughout its life cycle (ISO 14040). The collection of global aluminium industry data for use in LCAs was initiated by the IAI in 1998, although the Institute has been collecting energy and other relevant data for over 40 years.

LCA can be used to inform policy, material and design choices as well as provide a foundation to support broader sustainability efforts. The growing importance of LCA necessitates the availability of robust and up-to-date information on key stages in the product system.
