GREET is the Greenhouse Gases Regulated Emissions and Energy Use in Transportation Model. It is a software tool to compare “life-cycle impacts of vehicle technologies, fuels, products, and energy systems. It provides a transparent platform through which energy and vehicle producers, researchers, and regulators can evaluate energy and environmental effects of vehicle technologies and energy and product systems. For any given energy and vehicle system, GREET can calculate total energy consumption (non-renewable and renewable), emissions of air pollutants, emissions of greenhouse gases, and water consumption.” - GREET: The Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation Model | Department of Energy

OpenAir’s missions that touch upon transportation fuels production from carbon capture, will ultimately integrate with models like this or other MRV systems.
