-
Will the results of an LCA
always be 100% certain? No.
-
There are too many variables
with too much uncertainty for that.
-
As we saw in the first case study,
looking at different hand drying methods,
-
there was no real or absolute answer
to the question of
-
which method
was the most environmentally friendly.
-
This module looks at uncertainty
and variables as they relate to LCAs.
-
We will sketch out an idea
of different types of uncertainty,
-
and how we can go about calculating it.
-
You will learn how there are both
-
qualitative and quantitative methods
for such calculations,
-
the results of which will serve
as a starting point
-
for informed decision making,
-
the final topic of this module.
