How does a copper mine work out emissions from its haul trucks?
Litres of diesel issued to the haul fleet times about 2.68 kg CO2 per litre, as Scope 1 if the mine owns or controls the trucks. If a contractor runs them, it is Scope 3 for the mine. Track litres per tonne moved, because deeper pits and lower grades push it up year after year.
Owner or contractor
Control decides the scope. Owned or leased trucks you operate are Scope 1; a mining contractor's fleet is Scope 3 for you and Scope 1 for them.
The useful ratio
Litres per tonne of material moved, and per tonne of copper in concentrate. Falling ore grades mean more rock moved per tonne of copper.
Records
Fuel issue logs by truck, contractor fuel reports and tonnes moved.
What Senseible does here
Senseible reads fuel, electricity and freight invoices into a dated, fingerprinted record per site, so a copper product figure can be traced back to the documents behind it. Factors outside India are entered from the official source and labelled.
