Sure, and maybe I can start there.
One of the key drivers here involves the new regulations for greenhouse gas reductions. They will apply not just to light-duty vehicles, but heavy-duty vehicles as well. Right now in Canada, we're in the process of finalizing the heavy-duty regulations as well.
In order to actually achieve some of these very stringent targets—and by the way, we're kind of the only industry right now that is being regulated in terms of greenhouse gas emissions--with personal transportation making up 12.5% of greenhouse gas emissions in Canada and total transportation being about 27%, the fact of the matter is we're going to need all technology, a full slate of technology. So you will see the NG being part of that. You will see clean diesel being part of that. You'll even see improved internal combustion engines being part of that as you move through 2016, 2017, and ultimately 2025.
Electrification of the vehicle will come along through that process as well. The question will be, where will that stand relative to all these other jurisdictions as we go forward—particularly when you look at diminishing reserves of oil, for instance? I say that's perhaps even more important on a global basis, when you look at developing countries and their thirst for oil.
All these technologies will be absolutely necessary. So you will see, from my perspective, I believe, a complement of different technologies, and they'll be applicable to both personal transportation as well as commercial transportation such as heavy trucks, as in the case of compressed natural gas.
