About the ESIA

  • The ESIA was written to meet Project Finance requirements and was released for public review in August 2012.
  • It meets international standards required by Project Finance lenders, as well as our own high standards for addressing environmental and social impacts.
  • The first publicly released, independent audit of ESIA compliance was published in 2013, showing compliance with 678 out of 742 total commitments (91 per cent).
  • A subsequent independent audit published in 2016 found compliance with 728 out of 742 commitments (98.1 per cent).
  • Oyu Tolgoi currently has no areas of non-compliance which have been identified as requiring immediate corrective action.
