Do outsourced security guards and housekeeping staff count in our carbon footprint?
Their services count as Scope 3 Category 1, purchased services, usually estimated from the contract value with a spend-based factor. Their fuel and power on your site is already in your bills. Their commuting belongs to the contractor, not your Category 7.
What to include
- The annual contract value, by service.
- Cleaning chemicals and consumables if billed separately.
- Any vehicles the contractor runs for you.
What is already counted
Lights, lifts and machines the staff use run on your electricity bill, so do not add them again.
What Senseible does here
Senseible reads quantities, dates and units from your bills and invoices and shows the factor and source used on every line.
