Thank you, Mr. Chair.
I'm not going to try to pick on any of the witnesses here, so this is for whoever wants to answer this question.
We've talked about this incremental approach we're going to have to take in our infrastructure system, particularly in our gas infrastructure system. We'll put 5% hydrogen into the gas mix, first of all, and then move it up from there—three to five years each time—and see what happens from an effects perspective.
Was it prudent, then, for NRCan to move forward with a transformative approach, as opposed to an incremental approach, in looking at what the outcome would be as far as emissions go?
That question is for anyone.
