Environment Bill

Can I ask a question of the Minister again before she sits down? There are at least two types of canal boat. There are those that run on diesel engines, which may or may not pollute and be subject to some sort of regulation in the future. But then, of course, there is the odd steam canal boat. They are as much part of our heritage as steam trains, fixed steam engines or my noble friend’s big steam engines in Burnley. Just because a canal boat is moving on water rather than on rails or road, perhaps the Minister could look at that matter and perhaps help us.
