Sulfur Hexafluoride control of emissions units

Greenhouse Gases. Health and Safety Code 38505 identifies seven greenhouse gases that ARB is responsible to monitor and regulate in order to reduce emissions: carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), sulfur hexafluoride (SF 6), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and nitrogen trifluoride (NF 3).The fluorinated gases are also referred to as "high global ...
