The Resource Governance Index...measures the quality of governance in the oil, gas and mining sector of 58 countries. These nations produce 85 percent of the world’s petroleum, 90 percent of diamonds and 80 percent of copper...The future of these countries depends on how well they manage their oil, gas and minerals...The Index assesses the quality of four key governance components: Institutional and Legal Setting; Reporting Practices; Safeguards and Quality Controls; and Enabling Environment. It also includes information on three special mechanisms used commonly to govern oil, gas and minerals—state owned companies, natural resource funds and subnational revenue transfers. The Index finds that only 11 of the countries—less than 20 percent—have satisfactory standards of transparency and accountability. In the rest, the public lacks fundamental information about the oil, gas and mining sector.
