Thanks.
Now lets argue about environmentalism!
Personally, I think if the intent was really to benefit the environment, policies would focus first on the low hanging fruit. Canadian policy would be that everyone shuts the hell up about the rest until the residential building code is modified to require airtight vapour barriers and R-40 insulation. Biofuels are ridiculous by comparison to the benefit that would bring.
Unfortunately, the construction lobby is much stronger than the insulation manufacturing lobby, so no real changes will be effected.
