John will participate as a U.S. delegate and lead author in the United Nations Intergovernmental Panel on Climate Change’s upcoming effort to update how countries account for their greenhouse gas emissions.  Until recently, national greenhouse gas inventories have not included emissions from reservoirs, but recent work from our group and others has shown that this is a substantial oversight.  In an effort to correct this, the UN has commissioned a chapter of their revised guidance to the national inventory development process focused on reservoirs.  The first meeting for lead authors will occur in Bilbao Spain in June.
