In 2006, California passed AB-32, the Global Warming Solutions Act, which charged the California Air Resources Board (CARB) with monitoring and regulating statewide emissions sources of GHGs, and set a target of reducing statewide GHG emissions to 1990 levels by 2020. However, since the long atmospheric lifetime of SO2F2 was not discovered until 2009, SO2F2 was not included in AB-32. California renewed its commitment to emissions reductions in 2016 by passing SB-32, which expanded upon AB-32 and set a statewide GHG emissions reduction target of 40% below 1990 levels by 2030. Although CARB classified SO2F2 as a short-lived climate pollutant (SLCP) in 2016, it has yet to add the gas to the state’s annual GHG emissions inventory or its latest Climate Change Scoping Plan So this gas was recently discovered to be harmful, but the legal framework for tracking emissions hasn't yet been updated to include it. > From 2007-2019, California reports an average of 4.8 Tg CO2 equivalents (CO2e) yr−1 in statewide GHG emissions reductions under AB-32. (1 Tg = 1 million metric tons (MMT)). Notably, these emissions reductions slowed and plateaued to an average of 2.25 Tg CO2e yr−1 from 2010-2015. Our inverse model results imply an annual mean SO2F2 emissions rate of 0.7–1.7 Tg CO2e yr−1 (100-yr GWP) or 1.2–2.7 Tg CO2e yr−1 (20-yr GWP) for 2015-2017.

In 2000, emissions were estimated at 460 million tonnes CO2e. In 2020, 360 million tonnes CO2e. So sulfyryl fluoride emissions could account for approximately 1% of overall greenhouse gas emissions in California.
