In 2009, the Governing Council requested UNEP to update the 2008 report (Decision 25/5). The Global Mercury Assessment 2013: Sources, Emissions, Releases and Environmental Transport and its accompanying and updated Technical Background Report were the response to that request.
The inventory was based on national emissions data for the year 2010. In addition to atmospheric emissions, the report also provides for the first time the recent and available information on releases to the aquatic environment and aquatic pathways and transport.
