How much carbon I make?!

I've adopted a 60 ft pine tree. My tree has circumference of 26in. After all the calculation that I did to find the volume of my tree I figured out my tree has stored 136250.2451 Kg of Carbon inside it.
I have a hyundai accent which has a great gas milage but still after calculating my trips to school and work and amount of gasoline that I use for these trips I figured that I use 53 "my  trees" to store the carbon that I, only I, make per year.
And at last look at my footprint: 44.09 metric tons of CO2!!!! Yeah and that is only for one person, think about the entire city or even country and we're cutting more and more trees everyday!!!! :(
