So what ACT says is that creating a confidential reserve price at auction, while it may go some way towards making the emissions trading scheme (ETS) more functional, in fact simply is another way for the Government to set an artificial price for carbon emissions, and that's an artificially high price that could be five or 10 or 20 times what our competitors and trading partners are paying. And it doesn't need to be that way, because there are mitigations for climate emissions available at much lower cost per tonne than what is available in the New Zealand airshed.
