One of the pieces of advice that we've received is that some of the low-grade industrial heat for things like milk drying units, for example, become quite feasible at about $40 a tonne. Whilst you might say, well, at 40 bucks a tonne, you're talking about carpeting the country in trees. Actually, it becomes more feasible for Fonterra and other users of that kind of heat in their industrial process to swap out their existing technology for new technology. That is actually how the scheme is supposed to work. The problem is that because we've had this artificially low price cap, Fonterra's never been allowed to get to that point, so they've gone for forestry offsets instead. I know that seems counterintuitive, but that is actually how the programme is supposed to work.
