DOE is committed to using science, technology, and effective management to minimize fugitive emissions throughout the Department. To assist in achieving this goal the Department created the Fugitive Emissions' Working Group (FEWG).  The Office of Sustainable Environmental Stewardship established the FEWG to share information and best practices regarding inventory management, reporting, monitoring and control technologies, and environmentally preferable substitutes for high-impact greenhouse gases (GHGs) among DOE sites.  The group has focused on efforts to reduce sulfur hexafluoride (SF6) emissions from DOE operations, and also supports improved management of non-SF6 fluorinated fugitive gases.
