# We burn no fuel, but our buyer doubts our zero Scope 1. How do we show it?

Canonical: https://senseible.earth/answers/buyer-doubts-our-zero-scope-1

Show that no Scope 1 source exists: no generator, boiler, furnace, LPG, company vehicles or refrigerant equipment, or that any present was not used. Purchase ledgers with no fuel, a site list of equipment and a signed statement usually settle it.

## Check every source

- Diesel generator, even standby.
- LPG for canteens or heating.
- Company cars or forklifts.
- Air conditioners and chillers, which can leak refrigerant.

## Evidence

- Purchase ledger with no fuel lines.
- Equipment list for the site.
- A short signed statement.

## Small leaks matter

Refrigerant top-ups are Scope 1. If you had any, include them.

## 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.
