So going back to that part about being able to bank overachievement of carbon dioxide emission targets, I'm keen to know what the rationale for that process is. Wouldn't it have been tidy and neat to have just had an annual process, and either the emissions targets were met or they weren't met? Simple, black and white kind of thing. But this process of being able to roll over to a second year seems to me to be a degree of complication that will cause some concern and angst in the sector. And then similarly, proposed new section 179 refers to the same category 1 light vehicle importer being able to defer an obligation. Now this section says "applies in relation to obligation years 2023, 2024, and 2025.", so it's limited in that aspect. But a " vehicle importer may apply to the Director, in accordance with the regulations, to defer their obligation to meet the category 1 light vehicle importer fleet target for an applicable obligation year (year 1) until the following obligation year (year 2).", and so it goes on. This, again, formulaic, heavy on regulation approach seems to be fraught with difficulty from an administrative and logistics point of view. And so my question, really, to the Minister is: what is the rationale for both the ability to bank, and what is also the rationale for the ability to defer obligations as set out in this part of the legislation?
