  1. Includes hydrocarbons released to secondary containment facilities and subsequently recovered.
  2. Includes onshore exploration leases but excludes offshore exploration leases.
  3. 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.
  4. One megalitre is equal to 106 litres.
  5. One petajoule is equal to 1015 joules.
  6. CO2-e = Carbon dioxide equivalent (the basis of comparing the warming effect of greenhouse gases such as carbon dioxide, methane, perfluorocarbons, etc.)
  7. One kilolitre is equal to 103 litres.
  8. The BHP Billiton Total figure is inclusive of data from our closed Beenup site in Western Australia.
