Meridian had been using the industry standard "cover gas," sulfur hexafluoride or SF6. This gas is inexpensive and easy to use. It is also an incredibly powerful greenhouse gas that has a global warming impact 22,800 times greater than CO2. To address this, Meridian worked in partnership with the EPA and others to find alternatives to SF6.
