Program Update Sally Rand, EPA May 6, 2014

SF 6 Emission Reduction Partnership for Electric Power Systems ► Since 1999, members of the U.S. electric power industry and the U.S. Environmental Protection Agency (EPA) have been working together to identify and implement opportunities to reduce SF 6 emissions. ► SF6 classified as the highest GWP gas (GWP of 22,800 IPCC Fourth Assessment Report). ► Extremely long atmospheric lifetime of 3,200 years causes it to accumulate in the earth’s atmosphere for centuries. ► 84 partner companies ► 53 of these partners (64%) report through the GHGRP. ► Partners are leaders in their industry in efforts to reduce SF6 emissions ► Share information 2
