I'd also like to confirm the position that we hold: that National had, and has, a clear criteria that would need to be met before we are comfortable with bringing agriculture into the ETS or, indeed, a similar pricing mechanism. That is—and it's a message which we have confirmed over a number of years—that there needs to be science-based mitigation of the impacts of agriculture on greenhouse gas emissions. We understand that this bill introduces an emissions trading scheme. We understand that. There are parts of this bill with which we do not disagree, as Scott Simpson mentioned. However, there is a very strong—very strong—push in the New Zealand scientific and agricultural sector to develop science-based mitigation measures.
