Okay, pricing.
This has been well established in Massachusetts, which has actually done the data gathering on what happened with their toxics reduction. They found it saved business millions of dollars and saved the environment many tonnes of toxic substances.
I think the substitution principle should be in section 2 as a mandatory obligation for the government. I also think that these presumptive bans are very powerful in pushing forward substitution. When you have a substance of very high concern that is carcinogenic, mutagenic, whatever, you have a presumptive ban. The onus shifts to industry, and then industry has to prove either that it's safe or that there's no safer substitute and that it's absolutely necessary.
In the case where there is a safer substitute, they're out of luck. Their substance is banned, and the market will move to the safer substitute.
