I'd like to take this one, because we're in the area I know, namely, greenhouses.
A lot of the things you are mentioning or envisioning, like screens, double screens to keep the heat in, using glass that has more insulation properties, etc., they have already been adopted by most of the large commercial greenhouses, at least in British Columbia and Ontario.
Those things have been adopted already, and it's not necessarily driven by the price on carbon as the price to do business. It made good sense for sustainability and emissions, and also for the bank deposits for the actual company.
