A verifier is visiting our plant for our carbon inventory. What should we prepare?
Have the documents behind every number ready, the meters and weighbridge accessible, and the people who keep the records available. The verifier will trace a sample of figures from your report back to invoices, logbooks and meters, and check that what they see on site matches what the report describes.
Documents
- The inventory, with methods and factors.
- Fuel and electricity invoices for the period.
- Logbooks, stock registers and production records.
- Calibration certificates for meters and weighbridges.
On the day
- A walk through each emission source: boilers, DG sets, furnaces, refrigeration.
- The person who enters data, to explain how it flows.
- A quiet room and access to files.
After
Expect questions and requests for more evidence. Answer them in writing with the documents attached.
What Senseible does here
Senseible keeps every figure linked to its source invoice or bill with a fingerprint, so a verifier can trace a total back to the documents it came from.
