- Includes hydrocarbons released to secondary containment facilities and subsequently recovered.
- Includes onshore exploration leases, but exclude offshore exploration leases.
- This value includes the area to be rehabilitated while the project is operational, not the total area that will require rehabilitation at the end of project life.
- One megalitre is equal to 106 litres.
- One petajoules is equal to 1015 joules.
- CO2-e = Carbon dioxide equivalent (the basis of comparing the warming effect of greenhouse gases such as carbon dioxide, methane, perfluorocarbons, etc.)
- One kilolitre is equal to 103 litres.
- The BHP Billiton Total figure is inclusive of data from our closed Beenup site in Western Australia.
