Argonne's GREET Model

This brochure describes Argonne’s Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model, which is a one-of-a-kind analytical tool that simulates the energy use and emissions output of various vehicle and fuel combinations. GREET is widely recognized as the “gold standard” for evaluating and comparing the energy and environmental impacts of transportation fuels and advanced vehicles.
