SF6 Reductions from Non-Electric and Non-Semiconductor Applications

This page last reviewed March 03, 2017

Sulfur hexafluoride is a potent greenhouse gas, with a global warming potential (GWP) of 23,900, the highest identified by the Intergovernmental Panel on Climate Change. In October 2007, the California Air Resources Board approved sulfur hexafluoride reductions from non-electric and non-semiconductor applications as an early action measure and in February 2009 approved a measure (the Regulation for Reducing Sulfur Hexafluoride Emissions) to reduce sulfur hexafluoride emissions from other uses including magnesium casting, fume vent hood testing, tracer gas use, and other niche uses.

Sulfur hexafluoride emissions from semiconductor manufacture and electric utilities are regulated separately. On January 1, 2010, the regulation became effective and the reporting deadline is March 30 of each year, beginning in 2011.

What's New

Restrictions as of January 1, 2013 - In addition to the restrictions that had previously gone into effect, use of SF 6 for Tracer Gas Testing, Magnesium Sand Casting, Magnesium Investment Casting, and Military Applications (other than Military Tracer Gas Array use) is no longer allowed in California, beginning January 1, 2013, without a valid exemption from ARB. Please review the regulation here.

The next sales reporting deadline is March 30, 2017 - Please fill in the reporting form and return via email attachment to Dongmin Luo and Mackenzie Montrose prior to the end of the day on March 30, 2017.
