CARB: clean fuels replaced more than 50% of diesel used in California in Q1 2023

Green Car Congress

The alternative fuel’s CI value is divided by its Energy Economy Ratio (EER) in order to obtain the EER-adjusted CI value, representing the emissions which occur from the alternative fuel per MJ of conventional fuel displaced.

California ARB: GHG emissions fell below 1990 levels for first time in 2016; down 13% from 2004 peak; transportation emissions up 2%

Green Car Congress

The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.
