How do we count contract workers supplied by a staffing agency?
Energy they use at your site is already in your Scope 1 and 2, because you control the site. The agency's fee is a purchased service, Scope 3 Category 1. Many companies include contract workers' commuting in Category 7 with employees; say whether you do.
Where they appear
- Site electricity and fuel: your Scope 1 and 2.
- Agency invoices: Category 1.
- Commuting and company transport: Category 7, or Scope 1 if you run the buses.
Intensity
If you report per employee, state whether contract workers are in the headcount.
What Senseible does here
Senseible reads bills, fuel invoices and production records into dated, fingerprinted records, so the figure you send a buyer can be traced to its documents.
