Hon SCOTT SIMPSON (National—Coromandel): Thank you, Madam Chair. I've got a question that relates to clause 21. That's a clause that seeks to amend the Energy Efficiency and Conservation Act 2000. And, specifically, it seeks to amend that legislation by, "prescribing requirements in relation to the labelling of vehicles in terms of their carbon dioxide emissions and any financial rebates receivable or charges payable relating to those emissions". And so my question is: what exactly does the Minister envisage that labelling to be, and in what form, shape, or format will that labelling take? Is this to be something as simple as, maybe, another line on the registration that sits in the little pocket inside your windscreen? Or is this a requirement that will see a vehicle actually having a sticker or a sign or a piece of sign writing added to it? And what form or shape will the labelling take? Will it be required to be waterproof, protected from ultraviolet degradation, robustness? How will it be affixed to the vehicle? All those sorts of questions.
