Life-cycle Assessment (LCA) [Lecture]

Описание

The twelfth video in a series of very (very!) shortened lecture notes for an introductory environmental process engineering undergraduate course.

This video looks at the basics of life cycle assessment (LCA). The four stages of an LCA, the basics of the ISO standards, system boundaries, and who or why an LCA might be performed.
