Not disparaging IKEA at all--moves like this should be lauded--but this is a working forest, harvested for lumber. I can't speak to how sustainably it's harvested or anything, and while this is commendable, there is profit motive here, as IKEA is heavily dependent on wood for its products.
I think in general, supporting things like working forests from a government level (tax benefits) is probably something that isn't done enough, given forests are one of the best carbon sinks available to us.
