That's an excellent question.
Lumber or engineered woods such as glulam are the only building materials that are entirely renewable. Today, the National Building Code of Canada allows residential and other buildings of up to 12 stories to be built with wood alone.
In Ottawa, there are virtually no 12-storey buildings built with just wood. We still use concrete and steel, materials that have a very negative ecological footprint compared to wood, even when wood is burned. Forest products can store carbon in a building for 300 years. It's possible to significantly increase lumber consumption here in Canada, in our own market.
