I don't have the details about some of the different proposals. What I do have is some engagement that has come, frankly, from my other hat, from the diamond mines who are looking for opportunities to be innovative. Whether that is through renewable diesel project or others, I think I take the point that there are some ideas out there that are going to be innovative where, right now, if we're demanding proof of a 5-percent reduction as part of the application process, that may be a difficult target to be able to provide that advance proof of, if what you're trying to do is something innovative. There has to be a way to modify what we're doing to ensure that we're capturing that true innovation. That is something I've spoken about many times, and again, as I say, it may be simply a matter of an internal, small-R-type review that needs to happen so that the eligibility criteria are not excluding otherwise valid, good projects that will advance green energy and green mining.
