Yes, this is about the principle of substitution. This is obviously a clause we stood earlier, because there were some language concerns around the table.
The principle of substitution, if committee members will recall, is in a sense a higher order of effort on behalf of policy-makers and government. What it does is call upon the government to do a substitution analysis of some of the pollution we're talking about.
The reason I refer to this as a higher order is because the second order is that you start to talk about limits or caps or mitigation--mitigation being the last one--once the pollution is made and once people are sick or once the climate has heated up, depending on which topic you're talking about.
What substitution calls on the government to do is ensure that there is some substitution considered for the pollutant in the first place: are there other industrial applications that can be used?
We've seen the successful use in some U.S. jurisdictions. It is being brought in as one of the principles in Europe under the REACH regulation that you always, as the first order, assess if there is something else that can be used in the industrial application. Therefore the pollution is not made, therefore you don't have to limit it, and therefore there is no mitigation concept. It's the ounce of prevention versus pound of cure concept.
We stood this clause earlier. We allowed some language to be worked on, but we soundly believe in the principle. This is the most cost-effective way to go about doing things, both in the public and private sectors, because you just don't make the pollution in the first place. You don't cause the negative effects, you don't limit production, and you don't have to deal with the health or environmental consequences of pollution being emitted, because you just don't emit it.
It's something--and as a small part, I have a private member's bill, and there are other ones in the House right now--we probably haven't led the field on as a country, and we need to.
I seek perhaps a friendly amendment around the table that could clarify some of the language concerns, and we can move on.
