Step 4: Interpretation
LCA results are reported in the most informative way possible, and
the need and opportunities to reduce the impact of the product(s) or
service(s) on the environment are systematically evaluated. The
outcome of this step is directly useful in making environmentally
friendly decisions. LCA can be an iterative process; therefore, the
interpretation of the LCA can lead to changes in the proposed design,
which then leads back to Step 2 in the process.
