GREET Tools


GREET WTW Calculator

Based on the GREET model, GREET WTW Calculator summarizes WTW results of energy use, greenhouse gas emissions, and air pollutants emissions for different vehicle technologies with different functional units.


Alternative Fuel Life-cycle Environmental and Economic Transportation (AFLEET) Tool

AFLEET Tool is developed to estimate petroleum use, greenhouse gas emissions, air pollutant emissions, and costs of ownership of light-duty and heavy-duty vehicles using simple spreadsheet inputs.


GREET FLEET Footprint Calculator

GREET FLEET Footprint Calculator is developed to measure the petroleum displacement and greenhouse gas emissions of medium- and heavy-duty vehicles and off-road equipment with simple spreadsheet inputs.


Travel Carbon Calculator

Your vehicle's carbon footprint is more than just the tailpipe emissions and includes all the activities that are needed to get the fuel from its source to the car. Travel Carbon Calculator is developed to estimate your travel carbon footprint and find ways to potentially reduce it.
