That's something I also heard when I met with the mayors a couple of weeks ago. It's an initiative they're keen on. It's clearly one that has different impacts for different cities across the country that are in different situations. I think the focus of your work around pre-budget consultations is helping to get those sorts of ideas to the fore so we can analyze them and determine the things we should be trying to invest in, the things that are going to have the biggest impact on reducing our carbon emissions. That is certainly one.
I don't have any details on what we might or might not do in the budget yet. It's not appropriate to do that.
