Carbon footprinting refers to an LCA that is just tracking
carbon dioxide or greenhouse gases as the impact assessment metric.
This is a common occurrence
given the high profile of efforts to mitigate the impacts of climate change.
Some carbon footprints are about products, whereas others are about companies.
For corporate carbon footprints, we divide emissions into
direct and indirect emissions,
and we will discuss how to define the scope of those emissions.
This is important because it enables companies to understand
where they should prioritize their mitigation efforts.
Reducing indirect emissions from suppliers or customers
is often much more difficult for a company than reducing its own direct emissions.
You will have an opportunity to think about which scope of GHG emissions
is associated with several different types of activities.
