California Governor signs new super-pollutants legislation into law; black carbon, fluorinated gases and methane

Green Car Congress

signed SB 1383 , establishing the nation’s toughest restrictions on super pollutants including black carbon, fluorinated gases and methane. SB 1383 reduces the emission of super pollutants (also known as short-lived climate pollutants) and promotes renewable gas by requiring a 50% reduction in black carbon and 40% reduction in methane and hydrofluorocarbon from 2013 levels by 2030. Reducing these pollutants can have a more immediate beneficial impact on climate change.
