Certainly. I would be pleased to.
Railroads are four times more fuel-efficient than trucks, generating significantly less greenhouse gases than trucks, both for passenger and for freight. It's the greenest mode of transport.
There's been a lot of innovation done and efforts made. In fact, the RAC recently signed an MOU with Transport Canada on emission reduction. That's very exciting work to be done there in the next few years.
Things like alternative propulsion, alternative fuel and even battery and electrification throughout the passenger rail sector are also very interesting innovations, with exciting times to come in terms of being more sustainable.
