Colorado Greenhouse Gas Emission Tool (CO-GT) associated with article “A Colorado-Specific Life Cycle Assessment Model to Support Evaluation of Low-Carbon Transportation Fuels and Policy”

The Colorado Greenhouse Gas Emission Tool (CO-GT) is a Colorado-specific fuel life cycle model, that adopts many of the assumptions and methods of the Greenhouse Gases, Regulated Emissions and Energy Use in Transportation (GREET 2020) model developed by Argonne National Laboratory, excluding regulated emissions and energy use. The CO-GT encompasses the energy and transportation fuel system for the state of Colorado. The scope of this model is to define the well-to-wheels (WTW) GHG emissions for in-state production of fuels, production of imported crude oil and fuels and consumption of fuels along the fuel life cycle. Data used in this model were updated until 12/09/2020.
