Yes, Mike, I couldn't agree more, really, and that's exactly what I was just talking about in my own constituency. As you know—I know you've seen those figures as well—it's about making people understand that their actions affect others, not necessarily right where they are at the moment, but, you know, two miles down the road, where the air moves, and I think that's really important. So, we've done a number of things. We'll be having two big action categories. So, we'll have a big digital communications campaign, and we're also doing a lot of support for local initiatives in areas where we know that people need support for that. We're also really keen to support Clean Air Day and to develop a whole series of digital and physical resources to support local authorities, third sector organisations, schools, and other delivery partners to deliver those initiatives so that people do become aware of what we're doing, and the delivery plan for this Bill will include a large part of that.
So, in terms of this committee, we've got a budget that we think is sufficient to do the first bit of that piece of work. We've used the maximum cost within the ranges that we've done to calculate the £500,000 a year for that, and that's from 2024-25 onwards, because, obviously, by the time the Bill's gone through the Senedd, we'll be into the next financial year. I mean there'll be some variance, won't there, about how that works, but that's our estimate for it.
And a bit like the speed limits, really, and the way that emissions controls are changing on vehicles, that's a moving feast. Sorry for the pun. We'll have to keep an eye on that as the data comes in, and then educating people as to why it makes a real difference if you travel at the maximum efficiency of your engine and not very fast indeed, which is what the 50 mph limits are about, and how much difference that actually makes, is really important. And, again, we've got anti-idling provisions for outside schools; Mike, I know you've had that problem in your constituency.
So, it's a multipronged approach to a behavioural campaign, and, again, the Bill is not the only thing we're doing. So, we'll also be doing a whole series of behaviour change work around climate action and carbon budgets that will play into this space as well.
