Companies should use life cycle emission factors to calculate scope 3 emissions related to fuels and energy consumed in the reporting company’s value chain, except for category 3 (fuel- and energy-related activities not included in scope 1 or scope 2).
Compared to combustion emission factors, life cycle emission factors represent all emissions in the upstream supply chain of fuels and energy.
Where possible, companies should use life cycle emission factors that are as specific as possible to the type and source of fuel consumed (e.g., specific to the technology used to produce a fuel).

By default, life cycle emissions factor calculation is enabled for scope 3 activity categories. This corresponds with well-to-wheel emission factors. See pages 43 and 53 in the for further details.
However, as this is optional, you can toggle this off in Carbon+Alt+Delete in the under the tab "Emission Factors".
When life cycle emission in scope are turned on, the emission factors used will represent all life cycle stages of the fuels involved. See the following example for the activity category Business Travel.
In the above example, a flight has been added to the business travel inventory. You can open the "Life Cycle Stages" info box to see the full breakdown of the life cycle stages which are combined to create the life cycle emissions for this factor.
