Roughly 30% of transport-related greenhouse gases come from heavy-duty and medium-duty vehicles—in other words, light and heavy trucks. That is going to grow because we're the second-largest country on earth, and a lot of merchandise moves by truck.
There is potential in the early years for us to move towards zero-emission vehicles in the light and medium truck sphere, and also for trucks that do short distances, those that work within cities, that kind of vehicle. There are, in fact, companies in Canada now that are focused on zero-emission medium-sized trucks. There's a very promising future there. That is an area we hope to put more and more emphasis on in the coming years.
