The University of Florida has a sustainability goal of being a completely carbon neutral campus by 2025 and one of the easiest ways they can achieve it is to cut back on the number of faculty and staff who drive to campus each day.
Currently, transportation emissions account for 10 percent of UF's carbon footprint.
One Less Car Day is a campaign that encourages people to change their driving habits.
Organizers say they want to get people thinking about driving less and ways they can change their behavior without inconveniencing their lifestyle.
The program began four years ago.
Since it's inception, UF's Office of Sustainability estimates they have eliminated 100,000 car rides and stopped as much as 800 tons of carbon dioxide from entering the atmosphere.
