Replication Data for: DOE GREET Models and Data

Quoted from the original:  https://www.energy.gov/cmei/greet (accessed 1/23/2026) - 

“The Department of Energy (DOE) developed the GREET® (Greenhouse gases, Regulated Emissions, and Energy use in Technologies) life cycle analysis to assess the environmental impacts associated with technologies, fuels, products, and energy systems across various stages of the supply chain. 

For any given energy or transportation system, GREET can calculate: 

• Total energy consumption (non-renewable and renewable) 

• Fossil fuel energy use (petroleum, natural gas, coal)

• Greenhouse gas emissions 

• Air pollutant emissions 

• Water consumption.

• The Argonne National Laboratory R&D GREET Model is used to evaluate energy use and emissions output of transportation and energy sector technologies to assess research and development progress and inform RD&D direction.
  R&D GREET is available both as a Microsoft Excel file as well as a .NET tool.

BACKGROUND

The GREET suite of models was developed by Argonne National Laboratory (Argonne) in 1994, with the first version released in 1995. Its development and applications have been an integral part of DOE’s RD&D efforts to pursue energy and material technologies for energy efficiency, affordability, and environmental sustainability.

USE CASES

GREET models are developed for specific use cases, aiming to guide decision-making, research and development, and regulations related to the transportation and energy sectors.

Users are responsible for ensuring they have selected the correct model for their intended purpose. Stakeholders seeking a GREET model for purposes of compliance with a given regulatory program should review guidance specific to that program to ascertain the appropriate version of GREET to use.

For example, annual releases of R&D GREET are comprehensive in order to inform the life cycle analysis technical community and elicit stakeholder feedback. R&D GREET may not be the version of GREET adopted by independent regulatory programs (e.g., tax credits).
