[LCA] Chap. 1 개요

LCA is a concept to evaluate the environmental effects associated with any given activity

from the initial gathering of raw material from the earth until the point

at which all residuals are returned to the earth.

LCA consists of three complementary components:

inventory analysis,

impact analysis,

and improvement analysis.

The newest aspects of LCA are goal definition and scoping analysis

which serve to tailor the scope and boundaries to the study.
