Our carbon footprint jumped after we added supplier emissions. Did we get worse?
No. You counted more of what was always there. Scope 3 is usually the largest part of a manufacturer's footprint, so adding it raises the total even if nothing changed on site. Compare like with like: Scope 1 and 2 against last year, and restate last year with Scope 3 if you want a trend.
How to show it
- Keep Scope 1 and 2 as a separate line with last year beside it.
- Show Scope 3 as a new line, with a note on which categories are included.
- If you restate the earlier year, say so and say why.
What a buyer reads
Buyers expect Scope 3 to be large. A clear note that the increase comes from wider coverage reads as better reporting, not worse performance.
What Senseible does here
Senseible reads supplier invoices into dated records with the quantity, unit and factor on each line, and marks lines without a usable quantity as needing data instead of guessing.
