Environmental initiatives across the country have drastically increased the number of hybrid taxis on the streets, and this project explores how an app can encourage this positive green trend. Meet 'EcoGo'- a taxi app for the environmentally conscious. The app allows users to order rides from participating taxis, as long as they are hybrid vehicles. Passengers earn points for every gram of CO2 that they saved by riding a hybrid, which they can redeem for free rides. There is also an optional cab-sharing feature which doubles the user's points for that ride. EcoGo's logo combines the symbolism of transportation (location pin) & environment (leaves).
