One big idea to transform travel in New Zealand

New Zealand’s universities have a shocking record on emissions. If they band together, however, they could make a massive difference. Shaun Hendy explains.

Humour me for a minute by imagining that the University of Auckland was facing a 40% budget blowout next year. Of course, you chuckle, this would never happen. The University of Auckland is an organisation that would rather burn books than blow its budget.

But humour me. “Fiscal black hole!” the Dom Post would cry. “Millennials are killing our universities,” the Herald would warn. “Bring back Steven Joyce,” the NBR would demand, as required by its defamation settlement with the former finance minister. “Ten top ways to kill our literary scene with a lime scooter,” the Spinoff would suggest.

Pure fantasy, I know, because as I write, the University of Auckland is on track to over-run its carbon dioxide emissions budget by 40% and few seem to care. In its 2013-20 strategic plan the university set itself a 2020 target of 0.69 tonnes of CO2 per student in emissions, a reduction to 15% below 2011 levels. Since this plan was written, however, the university’s emissions have steadily risen. In 2018 they had grown to 1 tonne per student.

What’s gone wrong? According to the University of Auckland’s sustainability officer, Dr Lesley Stone, it is air travel that has thrown coals on the fire. And it is not just Auckland. Victoria University of Wellington (VUW) recently published a breakdown of its carbon footprint, with air travel the single largest source, accounting for 29% of its emissions. At 250kg of CO2 per student, this is the equivalent of a return flight from Wellington to Auckland every year.

This delightful metric hides the fact that it is staff, not students, who are racking up the air miles. Per academic staff member, VUW’s annual emissions from travel work out to be the equivalent of sixteen return trips to Auckland. Academics are busy people – places to be, Koru lounges to loiter in. What are our men and women in suits doing?

The University of Auckland has suggested “travel diets”, which emphasise the use of videoconferencing to replace face-to-face meetings. I took a year off flying in 2018 (and wrote a very reasonably priced book about it, available here and at all good bookstores), finding that I could use video to eliminate some trips. A year on, I am more sceptical – video conferencing has proved so efficient time-wise that it has grown my collaborative network, which in turn has created more reasons to travel.

Massey University and VUW are turning to offsets. Massey has said that it will purchase offsets for its flights on Air New Zealand. VUW has announced that it will impose a 5% carbon fee on university-funded air travel. Half the fee will go towards purchasing offsets, while the remainder will be used to support sustainability initiatives. Grant Guilford, do I have an initiative for you.

I would like to propose that our universities get behind faster, more frequent train services between major centres. Since my #nofly year in 2018 I have become a reasonably regular passenger on the Auckland-Wellington Northern Explorer, but the trip takes 11 hours and only runs three times a week on each direction. I don’t mind the 11 hours so much, as I can work quite happily on the train, but it takes a minor miracle for the infrequent service to sync with my schedule.

A recent study in Sweden found that decisions not to fly were driven by an awareness of climate change, something that is only going to increase as the effects of warming get worse. If the service ran daily, or even better, was supplemented by a night sleeper, I think many people would be prepared to choose rail over a flight.

Kiwirail seems less keen, preferring to focus on tourism rather than business travel. The Ministry of Transport’s 2017 briefing on regional rail to Phil Twyford said that “long-distance passenger services in New Zealand have been successful when they have concentrated on providing a unique travel experience rather than an alternative to road or air travel.” But to decarbonise our economy by 2050, we are going to have to fly less, something that would be a whole lot easier if rail was a good alternative.

This is why Wellington Regional Councillor Thomas Nash recently threw his weight behind the call for better train services. Nash has suggested on Twitter that “if a bunch of employers publicly committed to making bulk purchases of train tickets for their employees that might be the kind of evidence needed to make the case for a more regular Wellington-Auckland train service”. What if our universities were to make this commitment?

The Education Act says that universities have a responsibility to act as the critic and conscience of society, and one of the few places that this appears on their balance sheets is in their CO2 emissions. It’s well past time for universities to make a different kind of cut.

Keep going!

Twenty-four hours after the eruption on Whakaari/White Island, here’s what we know about the ongoing situation.


How many people have died?

Currently, the official death toll stands at five, but there are a further eight people missing, who are presumed to have died in the eruption. 31 people remain in hospital and three have been released from hospital.

Who was on the island when the eruption happened?

A mixture of tourists and tour guides. The name of one person who died has been released – tour guide Hayden Marshall-Inman who worked for White Island Tours. Tipene Maangi, another employee of the company, is currently missing.

Among the others on the island, many were passengers on the Ovation of the Seas cruise ship. Among them were a pair of young newlyweds, Lauren and Matt Urey, from the USA. They were rushed to hospital with severe burns.

Many of those caught up in the eruption were Australians. Visitors from the UK, China and Malaysia were also present, along with New Zealanders.

Will there be another eruption?

GeoNet says there’s a 50/50 chance of another eruption taking place within the next 24 hours. “We are still observing localised steam and mud jetting from the active vent area,” the organisation said in a statement. The Volcanic Alert Level remains at three, one rung higher than it was when the eruption took place yesterday.

Has White Island erupted before?

Many times. It’s the most active volcano in the country and this is its sixth and largest eruption since 2000.

What kind of eruption was this one? 

It hasn’t been confirmed, but experts have made informed guesses. Dr Marco Brenna from the University of Otago’s geology department said it “was likely an eruption caused by over-pressurisation of the shallow hydrothermal system under the crater of White Island.”

“Basically, input of fresh magma over the past month or so, indicated by increased seismicity and gas emissions recorded by GeoNet, provided heat and energy into the system (like switching on the heat under a pressure cooker). At some point, the shallow crust under the crater could not contain the increased pressure, and that caused the explosion.”

How are recovery efforts faring? 

It’s still difficult for emergency services personnel to get onto the island, and a significant amount of ash has now fallen. There is also the uncertainty around further eruptions, and the physical environment of the island is unstable. Initial rescue efforts were halted yesterday due to dangerous conditions.

Will ash clouds reach the mainland?

At this stage, it appears the vast majority of ash will not fall on the mainland, resting instead on the island and in the sea around it. Although that’s somewhat dependent on which way the wind blows. Regardless, those in the area have been told to continue closing all windows and doors to keep ash out of houses.

Should tourists have been on the island at all?

This is a question that’s increasingly dominated discussion around the tragedy. More than 10,000 tourists visit each year, and it’s an important aspect of the wider Whakatāne economy. However, the unpredictability of eruptions has led to experts suggesting the presence of tourists was a mistake.

Ray Cas, from the School of Earth, Atmosphere and Environment at Monash University, said White Island was a disaster waiting to happen. “Having visited it twice, I have always felt that it was too dangerous to allow the daily tour groups that visit the uninhabited island volcano by boat and helicopter. White Island lies almost 50 kms offshore from Whakatāne, and experiences significant explosive eruptions every three to five years.”

Should this eruption have been predicted, given the alert level was raised?

Despite the raised alert level, it’s still almost impossible to predict when an eruption of this nature will take place, said Dr Jessica Johnson from the University of East Anglia. “White Island/Whakaari is an andesitic stratovolcano, which means that it can have lots of different types of eruptions. It also has a water-filled crater lake. When water reacts with hot rock or magma, it can create explosions, and therefore, can make eruptions even more difficult to forecast.”

Are tourists who visit White Island made aware of risks?

Yes – they are given clear warnings that eruptions can happen, and are given breathing masks and hard hats to wear on the island. They are also given clear and repeated instructions to stay on designated pathways.
