No, the offsets won't be priced by government. The price of an offset will be set in the marketplace. Facing an obligation to reduce my emissions, hypothetically speaking, I have a choice: I know I can pay $20 a tonne, or I can buy surplus credit from the business down the road. How much is he willing to sell it for? Maybe it's $18 a tonne. Or I can buy an offset. I'll probably be willing to offer $17.90 for an offset. You're an unregulated party. You have the potential to develop an offset. You have to decide if can you reduce a tonne of emissions for $17.90. If you can, then you probably will, and you'll sell your credit to me. If you can't, you won't, and I won't have an offset to buy.
It will be set by the market, not by government. Provincial governments already set criteria for what a good offset has to be. So we know there are actual reductions, but then they are offered up into the marketplace, and the price is set by the market. It's a typical supply-and-demand arrangement.
