Sulfur Hexafluoride (SF₆) Emission Reductions from Gas Insulated Switchgear

This page last reviewed May 16, 2012

Overview:

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:

• ARB's Semiconductor Applications
