1
00:00:02,719 --> 00:00:06,512
Carbon footprinting refers to an LCA
that is just tracking

2
00:00:06,512 --> 00:00:10,560
carbon dioxide or greenhouse gases
as the impact assessment metric.

3
00:00:10,910 --> 00:00:12,679
This is a common occurrence

4
00:00:12,679 --> 00:00:16,678
given the high profile of efforts
to mitigate the impacts of climate change.

5
00:00:17,484 --> 00:00:21,842
Some carbon footprints are about products,
whereas others are about companies.

6
00:00:22,372 --> 00:00:25,551
For corporate carbon footprints,
we divide emissions into

7
00:00:25,551 --> 00:00:27,811
direct and indirect emissions,

8
00:00:27,811 --> 00:00:31,131
and we will discuss how to define
the scope of those emissions.

9
00:00:31,548 --> 00:00:35,001
This is important
because it enables companies to understand

10
00:00:35,001 --> 00:00:38,455
where they should prioritize
their mitigation efforts.

11
00:00:39,572 --> 00:00:43,760
Reducing indirect emissions
from suppliers or customers

12
00:00:43,760 --> 00:00:48,681
is often much more difficult for a company
than reducing its own direct emissions.

13
00:00:49,165 --> 00:00:53,153
You will have an opportunity to think
about which scope of GHG emissions

14
00:00:53,153 --> 00:00:56,489
is associated with several different
types of activities.
