0:00:02.519,0:00:06.656
We have seen the basis of LCAs,[br]learned about the goal and scope,

0:00:06.656,0:00:08.588
and looked at life cycle inventories.

0:00:08.928,0:00:13.830
Now it's time to review the procedure for[br]conducting a lifecycle impact assessment.

0:00:14.364,0:00:17.450
The lifecycle impact assessment[br]is the last major phase

0:00:17.450,0:00:20.687
of conducting an LCA,[br]and is the focus of this module.

0:00:21.471,0:00:25.825
In this module,[br]will identify the key elements in an LCIA,

0:00:26.042,0:00:29.212
as well as the optional steps[br]that are involved in the process.

0:00:29.763,0:00:34.464
Later, we will go on to outline[br]how to select which impacts to measure,

0:00:34.701,0:00:37.438
along with the[br]most common impact categories,

0:00:37.618,0:00:39.859
many of which you may[br]already be familiar with.

0:00:40.553,0:00:42.679
In the final section of this module,

0:00:42.809,0:00:45.662
we will examine impact assessment models.

0:00:46.196,0:00:50.817
There are some published models,[br]such as Impact World + and IPCC,

0:00:50.817,0:00:53.670
and we will understand[br]how using different models

0:00:53.903,0:00:57.924
can affect our LCIA[br]in terms of yielding different results.
