What we'd like to see is simply that prices reflect true costs, and that means financial costs and environmental costs as well, so that when a company is making a decision about an investment or an expansion or whatever the case may be, the bottom line they're looking at doesn't consider just the cost of the equipment, but looks at the cost of the environmental impact as well and incorporates that into the decision. If the costs are too high, the expansion of the project simply doesn't go ahead.
