What I'm trying to say is not that the technologies are the same, but that the term “pollution prevention” is broad enough to cover toxic substances, solid waste, greenhouse gases, and energy waste. It's a very broad term that was defined through a process that the federal government and provinces agreed to about a decade ago, precisely so that it would cover all of these issues.
If you distinguish between greenhouse gases and pollution prevention, then you're implying that the reduction of greenhouse gases is not covered under pollution prevention. That's the only point I'm trying to get at here.
