There's another question I'd like to ask in regards to clause 5, which inserts new section 167C, "Regulations for purposes of Part 13 (clean vehicle standard)". The question here is in regards to the issue of requiring vehicle importers to include among the vehicles they import in any given year a minimum proportion of vehicles with zero carbon dioxide emissions. This was another issue which was raised by a number of submitters. Some submitters requested the exclusion of this particular paragraph. So it'd be good to get from the Minister some of the rationale as to why he is dismissing that request to remove this particular paragraph. Effectively, what this paragraph—paragraph (m) in new section 167C(1)—does is t says if you're importing vehicles, a certain proportion, and we don't know what that proportion might be, has to be zero carbon dioxide emission vehicles—so, effectively, at this stage, an electric vehicle (EV) in the future, potentially using some form of other zero carbon emission type of fuel.
