This Good Practice Guidance is complementary to the HIA guide developed by the International Finance Corporation, the forthcoming guide by the World Health Organization and the guide developed by the International Petroleum Industry Environmental Conservation Association (IPIECA). The ICMM guidance focuses on an approach that takes account of emerging HIA methodology in both developed and developing country settings and the particular needs of the mining and metals sector. It describes a flexible and holistic approach that can easily be modified to take account of the needs and requirements of mining and metals companies and their projects.
