Global Warming Solutions Act of 2006 a 30% reduction statewide, with mandatory caps beginning in 2012 for significant emissions sources. The bill also allows the Governor to suspend the emissions caps for up to a year in case of emergency or significant economic harm. The State of California leads the nation in energy efficiency standards and plays a lead role in environmental protection, but is also the 12th largest emitter of carbon worldwide. Greenhouse gas emissions are defined in the bill to include all of the following: carbon dioxide, methane, nitrous oxide, sulfur hexafluoride, hydrofluorocarbons and perfluorocarbons. These are the same greenhouse gases listed in Annex
Sulfur hexafluoride also the method used by the discoverers Henri Moissan and Paul Lebeau in 1901. Some other sulfur fluorides are cogenerated, but these are removed by heating the mixture to disproportionate any (which is highly toxic) and then scrubbing the product with NaOH to destroy remaining . Alternatively, utilizing bromine, sulfur hexafluoride can be synthesized from SF and CoF at lower temperatures (e.g. 100 °C), as follows: There is virtually no reaction chemistry for . A main contribution to the inertness of SF is the steric hindrance of the sulfur atom, whereas its heavier group 16 counterparts, such as SeF are
