We have seen the basis of LCAs, learned about the goal and scope,
and looked at life cycle inventories.
Now it's time to review the procedure for conducting a lifecycle impact assessment.
The lifecycle impact assessment is the last major phase
of conducting an LCA, and is the focus of this module.
In this module, will identify the key elements in an LCIA,
as well as the optional steps that are involved in the process.
Later, we will go on to outline how to select which impacts to measure,
along with the most common impact categories,
many of which you may already be familiar with.
In the final section of this module,
we will examine impact assessment models.
There are some published models, such as Impact World + and IPCC,
and we will understand how using different models
can affect our LCIA in terms of yielding different results.
