I'm grateful. He's touched on a very important thing, which, as he's quite rightly said, hasn't been—apart from a short contribution from Dai Lloyd there—aired in this debate. He may be aware—well, he is aware, I know, but I just wanted to get it on record as well—in his own area, of course, there is the start of some of the answers to this twin dilemma of vehicle emissions and industrial emissions. He has the hydrogen research at Baglan. I understand that Tata put out a lot of hydrogen as waste gas at the moment—if only we could capture some of that and use it. It's right on the railway line—it could be used in a hydrogen train. The idea is just so exciting when you look at it that way. As well as monitoring the pollution in his constituency, which is important for everyone in Wales, we need to build on some of the technology that's there to plot that cleaner future.
