# We run our own locomotive in our railway siding. Is its diesel Scope 1?

Canonical: https://senseible.earth/answers/private-railway-siding-locomotive-diesel-scope-1

Yes. A locomotive you own or control burns diesel for shunting wagons in your siding, so it is Scope 1, at 2.68 kg CO2 per litre. Freight hauled by the railway on its own locomotives outside your siding is Scope 3 transport.

## Split

- Own shunting locomotive: Scope 1.
- Railway's locomotive on the main line: Scope 3 freight.
- Hired shunting service: Scope 3.

## Records

Fuel issue register for the locomotive and wagons placed and removed per month.
