  • 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.
