You can now use the Spend-based calculation method to calculate emissions associated with couriers and messengers, as well as warehousing and storage under Scope 3 Category 4: Upstream transportation and distribution and Scope 3 Category 9: Downstream transportation and distribution.
To use this calculation method, you simply combine your spend data with one of the following Plan A Categories:
Couriers and messengers
Warehousing and storage
The spend-based method helps businesses to screen their emissions until they have access to more granular business activity data. This reduces the time and effort it takes to report on emissions and identify hotspots for targeted emissions reduction actions.
