Cleaner fuels have replaced more than 3B gallons of diesel under California Low Carbon Fuel Standard

Green Car Congress

The program aims to reduce the carbon intensity of transportation fuels by considering greenhouse gas (GHG) emissions at all stages of production, from extraction to combustion. CARB developed the program to help support a return to 1990 levels of climate-changing gases by 2020, as required by AB 32, the 2006 landmark climate bill.

California clean fuels rule reports 100% compliance in 2017

Green Car Congress

The program considers greenhouse gas (GHG) emissions at all stages of production of a fuel, from pump or field to wheel. It was originally developed to support a return to 1990 levels of climate-changing gases by 2020, as required by AB 32, the 2006 landmark climate bill. Electricity displaced about 75 million gallons of petroleum.

Georgia Tech study finds MD electric urban delivery trucks have cost advantages over diesel in some conditions; relative benefits depend on numerous factors

Green Car Congress

The study found that TCO for electric and diesel medium-duty urban delivery trucks were similar. The electric truck is relatively more cost-effective on the NYCC and when VKT demand is higher. Cost-competitiveness of the electric truck diminishes in drive cycles with higher average speeds. Credit: ACS, Lee et al.
