Webinar to Discuss Proposed Amendments to the Sulfur Hexafluoride (SF6) Gas Insulated Switchgear Regulation

The California Air Resources Board (CARB or Board) has scheduled a webinar to discuss proposed amendments to the Regulation for Reducing Sulfur Hexafluoride (SF6) Emissions from Gas Insulated Switchgear (Regulation).  

The workshop will be held through the GoToWebinar online webinar system.  Staff will present slides and then respond to participant questions.

DATE:                Monday, July 13, 2020
TIME:                 10:00 a.m. - 11:30 a.m. (or until the discussion period concludes),

                           Pacific Time


Purpose of the Workshop

CARB staff is proposing to amend the Regulation to further reduce greenhouse gas emissions from gas-insulated equipment in the electricity transmission and distribution sector.  This workshop is intended to describe to stakeholders key elements of the proposed Regulation in advance of its formal comment period release.  

Relevant materials will be available on CARB’s Electricity Transmission and Distribution Greenhouse Gas Emissions “Meetings and Workshops” webpage prior to the workshop.

Workshop Information


As part of compliance with the Global Warming Solutions Act of 2006 (Assembly Bill 32), the Board adopted the Regulation in 2010.  The Regulation requires gas-insulated switchgear owners to lower their SF6 emission rate to one percent by 2020.  SF6 is the most potent of the six main greenhouse gases with a global warming potential over 20,000 times that of CO2 over 100 years.  It also has an extremely long atmospheric lifetime of about 3,200 years.
