id say 75% (random number) of the problem is down to us cutting tree's down and ruining the carbon "life cycle" more than it is burning so much fuel.

The problem comes when trees are cut down but not replanted. There's really nothing wrong with sustainable deforestation, when new trees are planted in place of the ones cut down.
