How do I calculate diesel emissions per tonne of material moved by dumpers at a mine?
Divide the diesel issued to haul trucks by the tonnes they moved in the same period, then multiply by 2.68 kg CO2 per litre. Use the fuel issue register and the weighbridge or survey tonnage. Haul distance drives the number, so report tonne-kilometres too.
Records
- Fuel issue register per dumper.
- Tonnes hauled: weighbridge, truck factor or survey.
- Average haul distance per bench.
Who reports it
Your own fleet is Scope 1. A hired contractor buying the diesel is your Scope 3, so ask for litres, not just the bill.
One month
- Diesel 84,000 L for 600,000 t moved
- 84,000 x 2.68 / 600,000 = 0.375 kg CO2 per tonne
