The environmental data for the calendar years 2008, 2009 and 2010 presented in this Annual Report 2011 is not directly comparable to that provided in the Company’s annual report 2010 and previous reports due to changes to the Company’s structure and developments in the Company’s environmental reporting arrangements. Specifically, these differences are as follows:

  1. 1. Discontinued operations have been removed for 2008, 2009 and 2010.
  2. 2. Inclusion of data from some additional joint ventures.
  3. 3. Movement to normalised absolute reporting (i.e. performance per tonne
    of production volume).
