I don't really get where your passive aggressive reaction suddenly comes from? The main claim, that it's CO2 neutral is false, so I'm trying to get a better understanding of your specific situation and we can maybe also do some napkin math. To do that, you need to provide some details such as what happens to the material that doesn't get turned into wood logs. And if you also know how much gas is being used to provide a certain amount of cubic meters of logs that's even better.
