How should a lignite mine contractor at Neyveli count diesel used to move overburden?
As Scope 1 if the contractor owns or runs the excavators, dumpers and pumps: litres of diesel times 2.68 kg CO2 per litre. For the mine owner, the same emissions are Scope 3 unless it controls the fleet. Surface lignite mines release little methane.
Who reports what
- Contractor operating the machines: Scope 1.
- Mine owner: Scope 3, unless the contract gives it operational control of the fleet.
Records
- Diesel issued per machine from the site tank register.
- Hours run and volume of overburden moved, for an intensity per cubic metre.
- Electricity for pumps and conveyors, as Scope 2.
Methane
IPCC defaults for surface mining give low methane per tonne compared with underground coal mines. Include it for completeness if the mine owner asks, using the surface mining default.
What Senseible does here
Senseible reads fuel, electricity and production documents into dated, fingerprinted plant records, so the monthly intensity behind a figure can be traced to its source.
