If we're talking about policy—and for an engineer that's going to be a new thing—the amount of regulation, the intersection between federal and provincial regulations that limit access to fibre in the industry, is probably one of the things that would block us the most going forward.
We're talking about using the forests. Canada is one of the places with the best usage of forests. It's a renewable resource. Managing the forest better and expanding the usage of forests is a path to reducing GHG, if you consider the forest as a sink for carbon. More usage of forests is better.
