Gasoline section shows results for fuel derived from both conventional oil and oil sands. We updated the latest version, GREET 1.8d, to include shale gas production and have revised the existing pathways for NG, coal, and petroleum. Expansion bars show the components of fuel production.

PRELIM uses a more comprehensive range of crude oil quality and refinery configurations than used in earlier models and can quantify energy use and greenhouse gas (GHG) emissions with detail and transparency the better to inform policy analysis, the duo suggests.

Vehicle energy-efficiency and emissions are the same for all fuels, except SO x emissions, which are lower for ethanol vehicles.
