GREET Is A Standard Tool for Well-to-Wheel Analyses of Vehicle/Fuel Systems

Government, industry, and academic researchers are developing advanced vehicle technologies and transportation fuels to help reduce transportation's oil use, lower greenhouse gas emissions and urban air pollutants, and boost energy efficiency. To assist these efforts, Argonne National Laboratory's Dr. Michael Wang has created a transportation analysis tool that allows users to systematically evaluate the energy and environmental benefits of such technologies and fuels.

The GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation) software model addresses the need for truly comparative full fuel cycle (or well-to-wheel) analyses. Developed in a user-friendly Microsoft® Excel platform with a graphical user interface, the model is available to the public free of charge.

The auto industry and governmental agencies maintain that GREET has become a "gold standard" for well-to-wheel analyses of vehicle/fuel systems.

Users that can benefit from GREET include government agencies, the auto industry, the energy industry, research institutes, universities, and public interest groups. Already, 9,000 GREET users in both the public and private sectors are registered throughout North America, Europe, and Asia.

To date, Argonne has used GREET to evaluate various engine and fuel systems for the U.S. Department of Energy (DOE), other government agencies, and industry (see publications list). Other organizations have used GREET to evaluate advanced vehicle technologies and new transportation fuels.
