I agree with a lot of what has just been said by Lee Waters, but I do thank Rhun for bringing this forward as a legislative proposal, and I certainly agree with the broad objective. Whether we need a legislative vehicle—sorry to use the pun—I'm unsure, but it's good that we are discussing these issues.

As Lee Waters said, we need to remember that the way we generate energy is key here, and moving to non-carbon sources is really essential. Also, it's essential to look at the issue of congestion in cities, which would not necessarily be achieved—or the reduction wouldn't necessarily occur—if we just replace current petrol and diesel vehicles with electric vehicles. However, electric vehicles are clearly very much part of the answer, indeed, not least in the public transport fleet. So, I think this is a really useful discussion and it's one where I want to see Wales moving ahead.

As Rhun said, at the moment, we do not compare particularly well with other parts of the UK. In 2012, there were just 53 electric cars in Wales; that had increased to 1,523 by 2016, which of course is a massive percentage increase but I think here the absolute number is really what we should be looking at. Other parts of the country have moved ahead quicker than us so far, so we need to look at this. It's all about where there are rapid-charging points. I think we'll need to look at public buildings first. We certainly need to look at the major road network because to travel between Anglesey and Cardiff and potentially not have a charging point is really problematic.

So, I think we need this to be part of a wide strategy, but it's definitely something where I think the public are going to push us even harder than we are prepared to go at the moment. There are a lot of issues here where Government needs to take the way in looking at it as an infrastructure issue, the huge stock of public buildings being an obvious place to start. You already see it in some developments—I've noticed it around the Vale of Glamorgan—that new housing does come with the charging points so that you don't have a long, clumsy lead to the back of your garage, but you actually see the charging point at the front of the house. 

So, that is where people will demand that the market goes, I think, but we need to facilitate that shift as well. So, I'm pleased this is being discussed and I've a very open mind as to whether it should be done by legislation or whether there are more traditional policy approaches that we can adopt.
