A key challenge facing many resource-rich countries is how to mobilize and effectively use volatile revenues from resource extraction, while addressing social and environmental externalities of mining activities. This UNEP Policy Brief examines how fiscal reforms and other complementary measures in the extractives sector can help generate additional public revenues while reducing some of the negative environmental and social impacts from mining activities. It also explores how these resources can be channelled through a well-governed sovereign wealth fund (SWF) or natural resource fund (NRF) to support delivery of the SDGs.
