Sulfur Hexafluoride (SF6) Emission Reductions from Gas Insulated Switchgear

This page last reviewed June 9, 2017


On June 21, 2007, as part of the California Global Warming Solutions Act of 2006 (AB 32) the Air Resources Board (ARB) approved the reduction of sulfur hexafluoride (SF6) emissions from electricity transmission and distribution equipment as an early action measure. Accordingly, ARB staff, in collaboration with interested stakeholders, developed a control measure to address these emissions.

ARB has undertaken other SF6 emission reduction measures for non-electricity sectors. Information regarding these measures can be found at these related links:
