If you read what was actually written you will realise that the savings referred to the last year. The practices have been in for sometime.
Air New Zealand says it has saved the enough fuel for 20 flights between Auckland and Los Angeles by plugging in to mains power while on the ground here during the past year. Instead of using big Auxiliary Power Units in their tails, jets are running off mains power to run onboard lighting, air conditioning and mechanical systems at the gate when the main engines are off.
They are implying this is a new way of doing things. If they've been doing this for ages then what AIR had to say was disingenuous or misrepresented / misreported by the N.Z. Herald in my opinion. I suppose at least 20 flights to the U.S. is something somewhat meaningful. From memory their entire electric vehicle fleet is saving them 70,000 liters per annum...less than 1 flight to the U.S. !

Nobody seems to care and are buying the greenwashing hook line and sinker. SP heading up into blue sky zone leading to reporting date. Heading for close to a record result ?

Investors / Fund Managers / instos don’t care much about climate change / environmental stuff. It’s all about P
E ratios and squiggly lines on a chart
They do just as much ‘greenwashing’ as the companies.

Cavotec will be familiar to Sharetraders as the company which brought out Mooring Systems.
Jet aircraft are supplied with electricity and cabin air from one of the main engines while they are running. They have an auxiliary power plant located in the tail which is refereed to as the APU(Auxiliary power unit) which provides these services(1) when the main engines are stopped.
The third source is GPU(Ground power unit) in which a power cable is connected to the aircraft. There is also the option in some cases to provide cabin air from a ground source as well.
Turbo prop aircraft do not have an APU. Travelers on Cullen Airlines ATR aircraft will have noticed a GPU cart with a diesel engine and a cable connected to the aircraft on the apron.
With the fast turn around times airlines are trying to achieve it is often less hassle to leave the APU running than to hook up a GPU.
This is slowly changing because of APU air and noise pollution, fuel costs and save the planet sensitivities.

(1) Also can be used to provide power for engine start up.
With the falling NZD... has anyone here sited any decent research on air travel demand and changes in the NZD currency. ps All over the hedge strategy, I'm thinking more market demand.
I would think domestic would be inelastic..international not so sure...
