We've heard such commitments before from this government, and they're not necessarily worth the paper or the audio capture.
The question I keep running back to is the official government policy, the one that you are mandated to negotiate upon. It talks a lot about potential economic harm to Canada's economy if we go too far, if we restrict greenhouse gases too much. Was it part of your negotiating package to be wary of setting limits or restrictions that were going to be too punitive on the Canadian economy?
