It makes sense to utilize mill by-products for energy production. CO2 will be released either way, through decomposition or combustion, so capturing its energy won't increase CO2 output.
However, harvesting new wood, "forest biofibre", is an environmentally poor choice for energy production. While it's growing, it's absorbing CO2. Once harvested, that CO2 is going to be released. Presumably some of this is just too immature to be harvested - let it grow. It can't do its important job of carbon capture once harvested.
Contrary to what our Progressive (sic) Conservative government seems to believe, climate change is real, and we are behind in changing our carbon intensive ways to deal with it. We must reduce our carbon footprint wherever possible, and instead of harvesting new wood that's serving an important purpose as a carbon sink, we should be investing in carbon free energy sources such as wind and solar.
