On the matter of environmental sustainability, again, here Mr Seymour's showing his inexperience again. This is a conversation with Air New Zealand. They want this. They know that the future profitability of any airline in the world relies upon adjusting to the carbon-constrained world that we're living in. Every airline in the world that wants to continue is working on this. So the idea that they would be engaging in the development of new aviation fuels is actually what will make them commercially sustainable into the future. Mr Seymour might deny climate change, but, happily enough, the aviation sector actually gets it, and they want to be a part of this.
