I apologize if I've misled the committee. Slide 6 summarizes the authorities that are currently in CEPA. So CEPA currently provides the government with the authority to establish a deposit refund scheme. The simplest example that we all know of is the deposit refund scheme existing in most provinces for cans, beer bottles, etc. CEPA provides the authority to establish that sort of a scheme as a means of addressing toxic substances.
Bill C-30 does not change that authority at all. What it does is amend the authorities respecting tradeable emissions units, which are different. Under a tradeable emissions scheme, a source would be given a certain number of units of emissions that it would be entitled to emit. If it emitted more than those, it would have to—If I emitted more than Ms. Roy, and she emitted less than her allotted level, then she could sell her units to me. That way, in total, we would come out at the right level. And she has an economic incentive to continue to lower her emissions. If I'm simply stuck because I have old technology and can't afford to upgrade, then I'll buy the emissions units that I need from her.
So what we've done is we've made a few modest amendments to those authorities to make that system work more efficiently, if we were to set it up.
