Thank you, Mr. Chair. And I think that's a much more useful -- useful metric because then we can -- we can factor it into those larger emissions pictures as we look for -- you know, actively seek for replacement technologies. I think it's very difficult when you're dealing with certain types of equipment, as the Minister said. So I just wanted to get a sense of what we actually look at and what's possible and what's useful fundamentally when we're trying to deliver on the climate change strategy and meet our net-zero goals, our 2050 net-zero goals. And that's probably a broader conversation that he will have to have with the Minister of Infrastructure. Nothing further, thank you.
