In 2015, NCST researchers began work on GreenFLY.ucdavis.edu, a demo flight search website that shows the emissions of each flight as prominently as the price, labels the lowest emissions options “Your GreenFLY,” and, by default, sorts flights from lowest to highest emissions. Experimenting with GreenFLY helped them to demonstrate the wide variation in emissions among flights with the same origins and destinations, especially for long cross-country or international flights.
