# Do printer toner cartridges count in our carbon footprint?

Canonical: https://senseible.earth/answers/office-printer-toner-cartridges-scope-3

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.
