Google might provide the answer but my goddammed PC won’t let me get that far before it crashes!
Doe anyone else have the answer?
There are certainly emissions from chainsaws, trucks to cart the wood etc to be considered.
Here in Tassie, there's a huge amount of controversy over forestry. It's a major industry certainly, and one which has an obvious impact on the environment.
Bottom line is that the "waste" wood is simply burned in the open to get rid of it, a practice that upsets a lot of people due to air pollution (these are pretty huge burnoffs, all done around the same time of year in Autumn).
By using it for firewood, I'm not causing anything to be cut or burnt that otherwise wouldn't be (apart from fuel in the truck etc). Figures I've seen on that basis put it at 0.06 kg of CO2 per kWh of heat delivered - a lot lower than coal-fired power (or gas) but more polluting than the 87% hydro and 4% wind that account for the majority of power used in Tasmania (but you could argue that the marginal source of power, a mix of gas-fired generation and imported coal-fired power from Victoria, is of course highly polluting).
In some ways I like heating with wood. A renewable fuel and it does give a nice heat. But then a point comes about this time each year when I'm absolutely fed up with all the hassle. Get home at 6pm in the dark, haul a box full of wood up the stairs, load the fire and light it, wait ages for the house to warm up. All up, I'm spending probably 50 hours a year, a full working week, messing about with heating the house. The idea of electric / gas or even wood pellets has a certain appeal in that regard that's for sure. I can certainly understand why wood heating went out of fashion decades ago, returning only after oil prices went up.
But then I already have the wood fire. And I have a mortgage that I'd rather reduce as a priority before worrying about changing the heating. And by the time Autumn comes, I'm actually looking forward to the idea of a nice blazing fire to sit in front of. Then a few months later the novelty has worn off. And so the cycle repeats...
