The Global Mercury Waste Assessment describes the current mercury waste management practices in selected countries around the world. The data relating to mercury waste, such as inventories, thresholds and mercury concentrations in municipal and hazardous wastes, were limited or did not exist, and the amount of mercury in waste at the global level remains unclear. One important finding, however, is clear: the gap between the provisions of the Minamata Convention on Mercury and the current mercury waste management practices is wide.

The assessment was developed by UN Environment with support from Zoï.
