In terms of costs on production, I think we canvassed that pretty well before the dinner break. It's sort of between, I think it was 1c a litre for milk and 3c a kilo for red meat—just to respond to that point. There was a question which wasn't asked before about processor-level obligations versus farm-level obligations. I will just make this point: there were actually dairy sector organisations that were arguing for a processor-level obligation, because if you're one of those processors and you've got—I don't know—25, 100 farms in your system, whilst you the organisation, the processor, would be the point of obligation, you'd actually be able to work with all of those farms collectively on a response. And we all know for some farms it'll be really easy for them to bring their emissions down quite a lot; other farm systems much more difficult to bring them down. Wouldn't it make more sense to be able to say, "Well, let's kind of net that out across the whole thing."?
