This report aims to build knowledge about how corporate cultures in mining companies influence how well those companies manage conflict with local communities. It is the product of a joint research project undertaken by the Corporate Social Responsibility Initiative at Harvard Kennedy School and the Centre for Social Responsibility in Mining at the Sustainable Minerals Institute of The University of Queensland in Australia. The research project recognized that factors external to mining companies can have a significant influence on the success of conflict management efforts; however, it started from a working assumption that the culture within a company also plays a substantial role. The project sought to test this assumption by identifying some general lessons that might be of use to mining and other extractive companies.
