This document discusses environmental challenges for natural resource-based industries. It notes that 20% of the world's population consumes 80% of resources, and if consumption levels don't change, four planets' worth of resources will be needed by 2050. Industries have major responsibilities to assess and address their environmental impacts through principles like precaution, responsibility, and green technology. UNEP works with industries through initiatives like the UN Global Compact to increase resource efficiency, investments in clean production, and consumer choice of sustainable products.
