Welcome to How Many Trees Does This Cost?

How Many Trees Does This Cost? is an app that measures your personal carbon footprint based on electricity usage (by state), flights(based on the number of passengers and the to and from airports), vehicle travels (based on distance and vehicle type), and fuel (based on the type of fuel and source). Interactive graphs display the carbon footprint and the number of trees needed to offset the carbon footprint. Animations show the number of trees on the screen.
