It certainly would. I would say in terms of reducing carbons, we shouldn't just rely on one strategy or two strategies. We need to use the whole arsenal of approaches and opportunities that we have. What we focused on was mainly operational energy, or carbon. When you look at buildings, over 35% of carbon emissions in Canada come from building operations such as lighting, cooling, and heating. That's 35% even without clean electricity. If you take the materials that we use to build our buildings, it's another 10% to 15%, depending on the estimate, so overall, it's about 50%.
Building taller buildings with wood is certainly something that's an opportunity to reduce the embodied carbon in a building. It makes a lot of sense. Even the cement industry is starting now to look at the lower carbon solutions available. Other barriers to wood buildings are the perception of people being in 18-storey or 20-storey wood buildings, concerns about fire ratings and those types of things. There is an opportunity for buildings maybe six to 10 storeys. You don't have to go 18 or 20 storeys, but it would require investment in the technology of these massive timber buildings. There is a significant amount of engineering involved and significant skills and precision to get these buildings built.
A final thought is that material selection is very important, but the operational carbon to operate the building over its lifetime would many times outstrip any materials that you use. So, given the time frame and the urgency you have, that would be my first focus.
