I guess I would argue that when you think about what sustainable development is, when you're thinking about the needs of future generations, you want to look at the decision you're making today and what the impact will be 20, 30, 40, 50, 100 years from now. If you're thinking like that when you're making those decisions, you're thinking about all three aspects on an equal footing.
But each decision will be different. The minister would have to make each decision, and may weight one thing more than the other. The problem we have right now is that when they're making those decisions, most of the time they have zero information about the environmental impacts, negative or positive—nothing. What we're saying is that they should be getting that information, and then how they weight the decision is up to the politicians, who make those calls. Sometimes they may weight something more strongly because they're thinking about the environmental impacts. Other times it may be a social reason that they make the decision. Other times it might be an economic reason.
What we're calling for is that the information be available to the decision-maker about all three aspects. Then they decide, based on the criteria in their head at that time, where to go. But at least they have that information.
