Maybe I can jump in.
There is a fairly standard life-cycle analysis tool that's been in use in Canada for quite a few years. Environment and Climate Change Canada is in the process of developing a new tool, and we're working with provinces and the private sector and academia. Our goal is to develop a tool that can become a standard tool for assessing the life-cycle carbon intensity of different fuels. We have sort of a prototype now, and we have the goal of rolling out that tool by the end of this calendar year. That's where we are in terms of the analytical approach.
Your question is a little more general. Well, it could be a little more specific.
What's the best fuel? I don't think any of us is going to give you a direct answer on that. Instead, I think what you're hopefully hearing from us is that the government's overall approach to clean fuels is one that is focused on creating incentives for the lowest carbon intensity possible, but not picking winners. We'll want to create market incentives that both drive and support research and development and production of lowest possible carbon-intensity fuels across their life cycle, recognizing that we are going to undergo a transition over the next few decades. We're not sort of putting a gold star on one or another but instead emphasizing that the lower, the better.
