I just heard the Conservative member talk about the costs associated with transition to net zero, with the idea that it's not important for the Government of Canada to also be greening and reducing its decarbonization, its own footprint in Canada, but I do think there are legitimate questions to ask about the costs associated with that.
Do you have an estimate for this committee? Was the cost an additional 10% to be able to make those buildings net zero? Was it 20%? It's important work, and we need to do it across the board, not just within the Government of Canada but across the country. Do you have a sense of that for this committee?
