You talked a lot about the ETS. That is a marvellous mechanism, and I think that's what we all support here. We want it to operate properly, and there was your example that you gave about not wasting opportunities to lower emissions and utilising the best signal to do that. But we've seen all around the world crazy policies that cost a lot, and I think the best example is the barrow bikes in Germany. Barrow bikes are a pushbike-type thing with a barrow on the front of it. People can cart their supplies from the shops on their bike, and the German cities thought it was a great idea to subsidise these barrow bikes. They abated a total of 7 tonnes at a cost of €20,000 a tonne. That is an example of a well-meaning policy attempting to lower emissions and, in fact, all it does is cost a lot of money.
