Why trees aren't good carbon offsets/carbon credits

1. If there is a forest fire, it releases a lot of CO2. Credits for these trees could still be circulating.
2. The amount per tree is still a big guess.
3. Planted trees may not survive.
4. Lumber companies could both set aside trees and get credits while doing unsustainable activities such as clear cutting.
