Do printer toner cartridges count in our carbon footprint?

Yes, as purchased goods in Scope 3 Category 1, usually counted by number of cartridges and a factor per cartridge or per kg. Remanufactured cartridges carry a lower figure. Printing electricity is in your Scope 2 already.

Count

• Cartridges bought per year, from invoices.
• Weight or a per-cartridge factor with its source.
• Used cartridges returned for refill.

Size

Small for most offices. Paper and IT hardware usually matter more.

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.

• IT hardware in Category 2
• Mobile and internet bills
