We (still) need to talk about cars

By Robert McLachlan

To address climate change, we need to phase out the burning of fossil fuels. The largest share of fossil fuels is burnt in cars and trucks. So it seems clear that fossil-fuelled vehicles need to stop being designed, made, imported, and driven. But anyone who has visited a road or seen a car ad recently knows that that isn’t happening, or, if it is, it’s happening so imperceptibly slowly as to hardly make a difference.

In New Zealand the situation is particularly acute, as we are now very, very far down the path towards a system dominated by urban sprawl and private cars, with little regulation of either. Road transport emissions doubled between 1990 and 2018. In the US they rose 30% in the same period, and in the UK, just 6%, which campaigners still point out is woefully insufficient.

Soon we will start to take steps to turn this ship around. It may or may not be quick, it may or not be easy. But it’s probably not going to be both quick and easy. As plans start to crystallise, there is certain to be a lot of back-and-forth between different factions.

Let’s take a look at the protagonists.

In the green corner: the climate advocates.

There are hundreds of advocacy groups, but a good example is 1.5 Project, led by Paul Winton. He points out that to fulfil our obligations under the Paris Agreement, we need to cut emissions 60% by 2030. Many sectors (such as the dairy industry, which creates huge emissions burning coal and gas to dry milk into milk powder) already have transition plans in place, and, in any event, are valuable and productive industries. So he concludes that road transport has to be virtually emission-free by 2030.

His and similar voices are being heard. For example, Auckland and Wellington councils have set made climate goals that require road transport emissions to at least halve by 2030. But targets like this are very, very difficult to achieve. They would mean essentially no new fossil-fuels vehicles entering the fleet, starting immediately. Unfortunately, hundreds of thousands are being imported every year, and people are buying them.

Passing to the red corner: the Labour government

The Government has a plan already prepared: the Clean Car Standard. It was developed and widely discussed in 2019 and taken into the 2020 election. It’s a fuel efficiency standard for new (or newly imported) vehicles, something that almost all developed countries have had for years, and that New Zealand would have had too in 2009, had not the incoming government of John Key blocked it. (You can read the official reasons in the cabinet papers; even in 2009 they must have seemed somewhat flimsy, and of course they have not stood the test of time.)

In the Standard as originally designed, the average fuel efficiency of all vehicles (of each importer) must meet a certain target that gets progressively more stringent. This was set at 161 gCO2/km in 2022, falling to 105 gCO2/km by 2025. The Standard was predicted to cut emissions  by 2 million tonnes of CO2 a year (about 13% of road transport emissions) by 2030, for a net savings of $2.4 billion.

From the Clean Car Plan proposal. I’ve tried to indicate the predicted 2 million tonnes savings by 2030 under the plan. Actually, I think the ‘BAU’ (Business As Usual, a terrible term) projection is pretty optimistic given our past and current behaviour.

OK, 13% savings, that’s a bit less than we need, but, wait a minute, there’s another player to consider….

In the blue corner: the car industry

This is a massive industry. Something like $6 billion of new cars are sold every year, in part thanks to $600 million of advertising. They are represented by the MIA (Motor Industry Association, for sellers of new vehicles), the VIA (Imported Motor Vehicle Industry Association, for sellers of used imports), and the MTA (all the above, plus resellers, petrol stations, and mechanics). Then there is the AA with 1.7 million members, half of all drivers in the country. I think it’s fair to say that they were all apoplectic about the government’s proposals.

You can read the MIA’s comments for yourself. They direct attention for emission reduction to agriculture, to the electricity sector, to the drivers of existing vehicles, and to the heavy vehicle sector – that is, to everywhere but the buyers of new cars, which is the area relevant to the MIA and to the plan itself. For the rise in land transport emissions, they blame previous governments, used vehicle importers, the lack of vehicle manufacturers in New Zealand, and buyers (for preferring utes and SUVs). They also blame external consultants and would prefer the industry to analyse itself.
Unlike the MIA, the AA does not blame car buyers (i.e., its members). However, they do blame car manufacturers for making larger vehicles, and Australia for having no fuel efficiency standard. They state, “The principal reason for the growth in transport carbon emissions is nothing to do with vehicle efficiency. It has been driven by population growth.” This does not seem to be the whole story. In the three years 2014–2017, emissions of light vehicles rose 13.7% while population rose 5.7%.

Neither the AA nor the MIA accepts any responsibility for the rise in land transport emissions, despite the fact that both organisations are heavily involved in it, the AA through its statutory role and through lobbying for more roads and favourable treatment for drivers, and the MIA through supplying vehicles and (especially) through advertising. Perhaps not surprisingly, the MIA does not favour any measure that impacts on the demand or supply of vehicles – the exact area in which its members operate. The AA says, “Lacking alternatives, much of New Zealand relies on motorised transport” – a situation due in part to the activities of the AA itself.

Both submissions say they recognise the need to reduce emissions from land transport, but neither organisation has shown much enthusiasm for the issue until now. As late as 2017 the AA were recommending ridiculously inadequate measures like educating people to drive more efficiently. The MIA’s industry-led proposal was found in 2008 to be overly complex and to have costs that exceeded its benefits. After it was dropped they don’t seem to have done anything on this issue until now. The MIA submission says they favour increased fuel taxes – how much, how often, will they tell their members and customers? More likely, they are saying this because they know it will go nowhere.

David Vinsen, chief executive of the Vehicle Importers Association, said the Government could instead “simply increase the excise tax on fuel to discourage emissions”. Simply? I don’t think so. 

Of course, these groups know now that fuel efficiency standards are actually coming. Should they cooperate in good faith, or should they try and distract and confuse the issue? Unfortunately, the MIA seems to have decided on the second strategy for the time being. A few days ago they launched their own proposal, to drop the standards entirely in favour of a feebate. The MIA’s feebate scheme exempts all vehicles between 100 and 230 gCO2/km (namely, the vast majority of all sales) entirely. They wouldn’t mind if the government chipped in to the subsidy part of the scheme as well, just to sweeten the deal.

You don’t need to run the numbers to see that the MIA’s proposal won’t have anything like the effect on emissions that is needed. In fact, it looks dangerously close to the strategy pursued by the oil and gas industry, described in Terrence Loomis’s recent book “The Predatory Delay Diaries: The petroleum industry’s survival campaign to slow New Zealand’stransition to a low carbon economy”.

But we’re not done, because, look over there… the public!

The public are perhaps the big unknown here. Any why shouldn’t we be? We hold diverse and often contradictory attitudes and behaviours. We can be fickle. 

We say that we’re getting more and more concerned about climate change, and three-quarters want the government to act more strongly on climate. 

But that’s easy to say. How would people really react if strong measures were introduced suddenly? Talk-back was running hot over Auckland’s 10c fuel surcharge, introduced in 2018, and that was enough to kill its roll-out elsewhere in the country.

I don’t think the Clean Car Standard as proposed will provoke too much unrest. It’s a gentle change, phased in gradually over a period of years. All economic and climate arguments support it. It fits the call for a “careful revolution”, in the words of David Hall. On the other hand, cars are emotional objects, and the National Party saw value in attacking the proposal last year in an ad that was later found to be misleading.

Climate change minister James Shaw said, “transport [emissions] have just gone up and up and up because we fell in love with the Ford Ranger” (a sound-bite I heard repeated on talk-back radio). The Ford Ranger, of which 10,000 are sold every year in New Zealand compared to 50,000 in the whole of Europe. “A pickup designed to last forever – just when its time is running out,” in the words of one review.

Perhaps the reason that the different parties are sounding so different here is that they have different views on the transport system as a whole. The car industry see the system as a free market, almost frozen in time, with themselves being minutely attuned to consumer preferences. The responsibility for emissions, if it lies anywhere, falls on each individual driver (or buyer).

Another view is that the entire transport system has built up over many decades as the collective result of many decisions by car manufacturers, oil companies, urban planners, central and local governments and many different factions within the public – including individuals, who can only make choices from those that are available to them. Responsibility for emissions is shared right across the spectrum. 

In climate circles there is a lot of talk of the need for a ‘just transition’. This originally meant taking into account the needs of workers in the coal, oil, and gas industries, which necessarily face major disruption; it can also mean making sure that inequality is not increased by changes such as carbon taxes. I suppose it could at a stretch refer to the makers and sellers of fossil-fuelled cars. But in New Zealand’s case we only have the sellers, not the makers, so there is less potential for an industrial hit. Second, some car companies have been dealing with emissions much more openly and positively than others. Shouldn’t they reap the rewards? Protecting the laggards just risks even more delay. Finally, I don’t think the industry as a whole really has anything to fear from the Clean Car Standard. 

Understanding climate change means knowing that road transport emissions have to come down. There’s a steady, sensible way to do start doing it. We should do it and then, once we’ve got the hang of it, work out the next step. And the car industry should embrace it as if its life depended on it.

New Zealand needs to start doing its fair share of climate action

By Robert McLachlan

Following this week’s climate emergency declaration, New Zealand will have to face up to the fact it has one of the worst climate records of industrialised nations. Of 43 industrialised countries, 31 are experiencing a drop in emissions. But 12 have seen net emissions increase between 1990 and 2018, and New Zealand is near the top of this group.

Source: UN

As part of the Paris Agreement, countries were asked to submit emissions reduction targets. These Nationally Determined Contributions (NDCs) are a measure of a nation’s commitment to contribute to the goal of limiting warming to well below 2℃. New Zealand submitted its NDC in 2015, with a headline target of bringing emissions down over the coming decade to 30% below 2005 levels. But this is not what it seems. New Zealand’s NDC confuses the issue by adopting a target of net emissions in 2030 compared to a baseline of gross emissions in 2005. This target actually allows New Zealand to increase net emissions.

Last year, New Zealand introduced the Zero Carbon Act, making it one of few countries to have a zero-emissions goal enshrined in law. But current short-term policies do not yet keep up with the ambition to reach net zero emissions by 2050.

Fair and ambitious climate action

It was clear at the time of the Paris Agreement that countries’ initial targets would be woefully insufficient for limiting warming to well below 2℃. Therefore, the agreement requires countries to show a “progression over time” to reflect each country’s “highest possible ambition”.

In addition to increasingly more ambitious targets, countries were also asked to explain why their intended contribution to the common aim was fair. Many did so, but not New Zealand. Some countries argued their contribution was fair because their total share of global emissions was small. Others said their per-capita emissions were small, while some high-emitting nations pointed out their per-capita emissions were falling. If those arguments weren’t applicable, some countries said it was particularly hard for them to reduce emissions, so their fair share should be smaller.

As any child in the playground complaining “That’s not fair!” would recognise, these are just self-serving excuses for inaction, rather than justifiable bases for determining fairness.

But what is fair, and who decides?

The official United Nations (UN) review of climate plans won’t happen until 2023. For now, we have to rely on outside assessments. Two major ones, by Climate Action Tracker and the Climate Equity Reference Project, illustrate some possible approaches.

Climate Action Tracker argues an approach is fair if it would lead to the outcomes agreed in Paris, were it to be followed by all countries. On that basis, New Zealand’s NDC was rated insufficient, consistent with a world that would be 3℃ warmer.

The Climate Equity Reference Project attempts to determine universally agreed criteria of fairness, based on UN agreements and on discussions with social, environmental, development and faith groups around the world. They found there should be a component of historical responsibility — who got us into this mess, and who benefited from it?

This can be assessed by cumulative emissions from some starting point, such as 1850 or 1950. There should also be an element based on a country’s ability to act, assessed by GDP above a certain threshold. Under this approach, New Zealand’s target would need to be for net emissions to reach zero by 2030, and to go negative after that by storing carbon and by investing in emission reductions in other countries. These conclusions were recently endorsed in a detailed study by Oxfam NZ.

Zero net emissions by 2030 is just not possible. New Zealand hasn’t even started reducing emissions yet.

Wealthy nations should shoulder more responsibility

So what can you do when you’ve agreed to something that you can’t achieve? The first step has to be to acknowledge the situation and to determine a fair contribution. New Zealand hasn’t done that yet — our present NDC (updated in April 2020 to reflect the Zero Carbon Act) does not mention fairness. The second step is to work out the highest possible ambition. For example, New Zealand could follow the EU lead of cutting emissions by a further 42–48% in the next decade.

The Climate Change Commission, set up under the Zero Carbon Act, gives New Zealand a framework for addressing this. The commission is expected to release a consultation document in February, reviewing the NDC and preparing emissions budgets out to 2035. The commission’s chair, Rod Carr, has acknowledged the importance of fairness in determining the NDC, saying:

I think fair share is a really good conversation for New Zealanders to have […] We’re a wealthy, developed nation. The wealthy nations, with the higher incomes per capita, do have a responsibility for doing more than the average.

The commission will also advise on how much of New Zealand’s contribution should be met domestically or internationally, and how much should be met by planting trees versus actually reducing emissions. The latter is already a contentious issue, as the payments for “carbon farming” (which New Zealand’s Emissions Trading Scheme, uniquely in the world, includes) are leading to unrest in the farming and environment sectors.

If people are paid to store carbon in trees today, who bears the responsibility for maintaining that store indefinitely, and who bears the risk should it fail?

Climate change minister James Shaw has acknowledged the present target is weak, compared to what the US, EU and China are now considering, and that he is expecting a stronger target to be recommended by the commission next year.

New Zealand has put in place new institutions and mechanisms to cut emissions and to phase out fossil fuels. Now, we put them to work.

New Zealand weighs up a nation-sized battery

By Ian Mason and Robert McLachlan

The present Lake Onslow, Central Otago. Source: Wikipedia

Climate change was a small but perceptible part of the recent election. On climate change, Labour pointed proudly to their record of legislating for net zero emissions by 2050 (nicknamed the ‘Zero Carbon Act’), establishing a Climate Change Commission to set carbon budgets and advise the government, and for strengthening the Emissions Trading Scheme by adding a falling cap on emissions.

But on closer inspection, all is not well. There is a serious gap between words and actions, the same gap that bedevils climate action in many countries. In fact, Climate Action Tracker rates New Zealand’s actions as ‘insufficient’, and consistent with a +3ºC world. How can this be?

Per capita greenhouse gas emissions are high, at 16 tCO2e. Gross emissions are up 24% on 1990 levels, and have not reduced in the entire 17-year operation of climate legislation. Transport emissions have doubled since 1990; New Zealand now has the highest vehicle ownership rate in the world, and recent years have seen the start of a large-scale motorway-building programme, supported by both major political parties. The Emissions Trading Scheme suffers from a carbon price that is too low ($35/t) to cut emissions, combined with too little coverage – export industries are largely exempt.

We often hear that New Zealand has a lot of renewable electricity. Electricity generation in 2019 was 58% hydro, 17% geothermal, 5% wind, 1% biomass, 13% gas, and 5% coal. Sounds pretty good, right? And yet in a time of climate crisis and supposed action, no fossil fuel plants have closed since 2015, and no new wind farms have been completed since 2014 (although activity is now starting up again).

Clearly something has to give at some point. That point could come next year, after the Climate Change Commission releases their first major advice in May 2021. But into this mix the Labour Party has introduced two striking election policies: one, to commit to 100% renewable electricity by 2030, and two, to fund a study and initial work on a stupendously large pumped hydro power station at Lake Onslow in the South Island.

For the high renewables percentage masks some fundamental problems with the system. The hydro lakes are not large, containing just 4 TWh of storage in a country with annual electricity consumption of 40 TWh. It only takes a few months of low rainfall to send prices and emissions higher. Even worse, the lakes are fed by snowmelt in spring. This creates an imbalance of about 2 TWh between hydro supply (highest in spring and summer) and demand (highest in winter), currently covered by fossil fuels. The imbalance can also lead to the lakes overflowing, wasting energy. Finally, the whole country faces a ‘dry year risk’. Every 5 or 10 years supply is unusually short, and households and industries are asked to save electricity. This risk is permanently priced in.

And that’s just the present situation. To decarbonize the whole economy will require a lot more electricity. Hydro is largely maxed out. There is scope for more geothermal energy, although the best sites have been built already, and most fields are not truly low-carbon or indefinitely sustainable – typically plants are designed to deplete the field over 50 to 100 years. That leaves solar and wind. 

Enter the nation-sized battery. Engineers know well that pumped hydro is overwhelmingly likely to provide the majority of energy storage in decades to come, and will be needed to balance intermittent renewables. But most systems contain only a few hours or days of storage. The Bath County Pumped Storage Station in Virginia has a large capacity  of 3 GW. But with its 24 GWh of storage, it can only run flat out for 8 hours.

The opportunity at Lake Onslow is due to the combination of demand, outlined above, and the special geography of the region. The storage lake would be created with an earth dam with an 80 metre operating range at a large, gently-sloping, high-altitude schist basin, connected to another lake (part of the existing hydro system) 700 metres below, via a 20-kilometre tunnel. In one scenario, 1.2 GW of generation is matched to 5 TWh of storage, more than doubling the capacity of the entire hydro system of the country. It could run continuously for six months. The largest configuration has up to 12 TWh of storage.

Proponents describe numerous benefits of the Lake Onslow pumped hydro station, first proposed by Earl Bardsley in 2005. It would balance a large amount of new wind and solar on time scales of hours. It would provide seasonal balancing on a scale of months. It would prevent spilling in the rest of the system and allow the other lakes to maintain more constant levels. It would allow decarbonization of the electricity grid, and of a lot of industrial process heat use and transport as well. The cost (perhaps $4 billion) could add 0.5c/kWh to all other electricity; but it’s possible that, overall, the net cost of electricity would be lowered. It would make private investment in new wind and solar more attractive, by putting a floor on spot prices. Every five or ten years, when a dry year comes along, the full capacity of the lake would be called into use.

If pumped hydro is such a great idea, and is urgently needed for the future worldwide, why isn’t it happening already? A 2016 review by Edward Barbour and others points to some of the problems. Consider the example of Germany. Germany has seen a rapid expansion of renewables, to the point where electricity generation is now 29% from wind and 8% from solar. That should have created an ideal environment for pumped hydro. Instead, the opposite happened. Declining wholesale prices for electricity during the daytime reduced the opportunity to buy low (at night) and sell high (during the day), to the point where even existing pumped hydro facilities became unprofitable and closed.

The Barbour study found that 95% of pumped hydro stations are publicly owned or operate in monopoly conditions. The authors write:

A major reason for this is thought to be due to the regulatory and financial uncertainty surrounding the integration of Pumped Hydro Energy Storage into liberalised electricity markets, which increases the risk, without providing the certainty of rewards over longer-time frames.

Regulators have struggled to find a model that balances the benefits to consumers, to the private and publicly owned generators and retailers, and to the environment, all on different time scales. This could justify direct public capital investment, especially at a time when governments are seeking labour-intensive, ‘green rebuild’ projects, and can borrow for close to nothing. It also points to a need to modify the market structure in the future to incorporate pumped hydro. 

However, there is a political dimension to the Lake Onslow project too, especially relevant at election time. “100% renewable” is a catchy slogan; a large civil engineering project doesn’t threaten anyone’s lifestyle today, the way a hefty carbon tax or regulation of car sales might. Climate politics requires gaining support for actions today whose benefits extend far into the future.

Carbon neutral jet fuel

By Paul Callister and Robert McLachlan

At an industrial park in Herøya, south of Oslo, Norway, a site has been cleared for the construction by Norsk E-fuel of a factory that will produce the world’s first climate-neutral jet fuel on a large scale. By 2026 the plant will be producing 100 million litres of aviation kerosene a year, enough to cut emissions by 200,000 tonnes of CO2 annually.

Although the scale is new, the building blocks of the technology are not. Electricity from hydropower (in commercial use since the 1880s) is passed through water to produce hydrogen, a process discovered in 1800. The hydrogen is reacted with carbon dioxide in variants of the Fischer–Tropsch process, widely used since the 1920s, to produce liquid fuels including jet kerosene. The carbon dioxide supply is the most innovative part – most commercial production today comes from burning fossil fuels, which is of course not climate neutral. Instead, it will be captured directly from the air by Climeworks, a company who have been doing just that since 2017.

This synthetic jet fuel, called Power-to-Liquid or e-fuel, is already approved for use in current aeroplanes.

If it’s all so simple, and the technology is ready to go, why isn’t it being used already? 

From an economic point of view, it comes down to cost. The industry needs to grow in order to achieve economies of scale, and also so that costs can reduce over time by learning from experience. That’s the standard picture of technological spread, from phones to solar panels. But it can’t get started, because it can’t compete on price with fossil fuels. Kerosene is cheap, and even under optimistic assumptions on the availability of cheap renewable electricity, e-fuels will still cost twice as much by 2050. 

However, we can’t wait for 2050. Until Covid-19, global aviation was growing strongly, having doubled in the past decade. It was projected by the industry body IATA to triple further by 2040. In fact, by 2050 aviation could be using all of the available carbon emissions available under a 1.5ºC scenario. Achieving the goals of the Paris Agreement will require strong action on aviation well before 2050.

This growth has been fueled by a concerted effort from the aviation and tourist industries, supported by governments (who often own airlines and airports and see aviation as a tool for growth) and international bodies like the UN’s International Civil Aviation Organisation and the World Tourism Organisation. As a result, jet fuel is untaxed, international airfares attract no sales tax or carbon tax, and international aviation emissions are not yet part of national targets under the Paris Agreement.

Furthermore, modelling by Paul Peeters of Breda University finds that standard methods of reducing demand, such as very steep carbon taxes and ticket surcharges, can’t do the job by themselves. Economic growth and the increasing comfort and convenience of long-distance air travel will still lead to overall growth. In addition, the industry is likely to vigorously resist any extra charges, or indeed any attempt to reduce demand at all. They can do this quite easily because positive action requires international cooperation.

In an impasse like this, something has to break. E-fuels offer a way forward. They increase the cost of travel and reduce emissions at the source. But to expand beyond their first trial facility, they need help. Climate advocates, some tourist bodies, and the e-fuel industry are calling for a tax on jet fuel, a mandated e-fuel requirement (for example, a 10% blend by 2030), and direct investment by governments. Support for large quantities of renewable electricity is also needed.

Climate advocates might be wary at this point, and they would be right. Aviation, like many other industries, has long been guilty of selling stopgaps and technological smoke-and-mirrors ‘solutions’. For decades these have failed to come to pass, because there was not enough incentive from industry, governments, and the public to push them forward. Some have been a deliberate delaying tactic: Leave us alone, we’ve got this. Meanwhile, most of the money goes into developing marginally more efficient fossil fuel-burning machines and promoting growth. 

So far, a key stumbling block has been the lack of widespread acceptance in the industry that emissions need to start decreasing now, and to eventually be eliminated. The challenges are not really technological or economic, they’re social.

The aviation industry is now in an unparalleled crisis, although it will surely survive in some form. The industry is vital to New Zealand. Although we may not return to the days when 33 different airlines flew here, Air New Zealand itself may well emerge relatively stronger. It’s less indebted than many airlines, it has long been focused on sustainability, and it has government backing and a strong domestic market. But, whatever the pace of the recovery, environmental concerns about aviation emissions are not going to go away. New Zealand’s potential for renewable energy and our early steps towards green hydrogen (made from water and renewable electricity) put us in a promising position to develop e-fuels.  

The Covid-19 pandemic gives us a breathing space, a time to reflect and to plan. A dangerously unsustainable industry can acknowledge that it needs to set out on a better path. We can ensure that future investments, and bailouts, lead to genuine emission reductions and that aviation plays a fair part in a more balanced and sustainable world.

New Zealand voters divided on climate


By Robert McLachlan

New Zealanders are polarised on climate change policy, according to a recent Stuff/Massey University survey of 55,000 readers. This puts the two major political parties in a difficult position as they seek options that are credible yet appealing to voters.

Just 30% of Labour voters and 22% of National voters think the country is “more or less on the right path” on climate action.

The majority of voters on one side of the political spectrum wants to see “urgent action and radical change”, while at the other end most recommend caution and scepticism.

The survey helps explain the deep distrust climate advocates have for the National Party, and their demands for bolder choices from Labour.

Where the parties stand

Labour is running heavily on its record, including the passing of the Zero Carbon Act and the introduction of a falling cap on emissions permits issued under the Emissions Trading Scheme.

Although the government’s COVID-19 recovery spending has been criticised for not being green enough, Labour seems aligned with a “just transition” approach championed by the International Labour Organisation.

Labour’s climate headline policy is for 100% renewable electricity by 2030, five years earlier than planned, and to spend NZ$100 million developing a pumped hydro scheme. Labour is also sticking with a plan for a nationwide fuel efficiency standard, which would begin to turn around New Zealand’s growing transport emissions.

The party has dropped the electric car rebate, which the National Party has attacked on the grounds it could increase the price of popular vehicles. A similar approach worked for the Australian Liberal Party in 2019.

The Green Party would go further. While also promising 100% renewable electricity by 2030, the party promotes home solar and insulation and community clean energy. More boldly, it would immediately ban new fossil-fuelled industrial boilers and end industrial coal use by 2030 and gas by 2035. It would prioritise free public transport for under-18s, ban petrol car imports from 2030 and create a NZ$1.5 billion cycleway fund.

The National Party has released its electric vehicle policy, with a target of 80,000 electric vehicles on the road by 2023 (up from 16,000 now). It would exempt these vehicles from fringe benefit tax until 2025 and from road user charges until at least 2023 to encourage uptake by commercial fleets. It would also target a third of government vehicles to be electric by 2023 and allow electric vehicles to use bus and carpool lanes. The last point has been criticised for impeding the flow of buses.

On the other hand, National’s climate spokesperson, Scott Simpson, has called the party a “broad church” and pledged to amend the Zero Carbon Act to emphasise that food production should not be sacrificed for climate goals.

The ACT Party, which on current polling would increase from one to ten MPs, was the only party to oppose the Zero Carbon Act. It now proposes repealing the act and tying the price of carbon to that of New Zealand’s five top trading partners.

What a difference three years make

At the time of New Zealand’s last general election in September 2017, Extinction Rebellion and the School Strike 4 Climate movements did not yet exist. Greta Thunberg was unknown to the world.

Now climate activism has increased globally. Climate-change impacts, including temperature records of 38℃ in northern Siberia to 54℃ in Death Valley, have attracted widespread attention. Orange skies in San Francisco are a reminder of apocalyptic Australian bushfires less than a year ago.

There are also signs of bolder climate action that may fulfil the declarations of the Paris Agreement. In the European Union, negotiations are under way to cut 2030 emissions to 40-45% of 1990 levels. This target would require halving emissions in the next decade. In the US, the Democratic presidential candidate, Joe Biden, has a US$2 trillion proposal for rapid decarbonisation. Ireland’s new government has agreed to emission cuts of 7% per year. China has pledged to be carbon-neutral before 2060. In New Zealand, both Auckland and Wellington councils have released highly ambitious climate plans that will require sweeping changes to housing and transport.

But this year’s New Zealand general election won’t be about climate change. The COVID-19 crisis and the high level of uncertainty about economic recovery and employment have made issues of leadership, trust and party branding more important than ever.

In this context, Labour’s nod to the Lake Onslow pumped hydro project could be a winner. Its storage potential is enormous – more than all of New Zealand’s present hydro lakes combined and 15 times the size of Australia’s Snowy 2.0 project.

It could decarbonise not just all electricity generation, but a lot of industrial process heat and transport as well. It would address the seasonal imbalance between lake inflows and electricity demand, and protect against dry years. But it’s also a traditional civil engineering project far in the future and doesn’t threaten anybody’s lifestyle today.

In New Zealand, as elsewhere, climate politics means finding support for actions now whose benefits extend far into the future.

Flight to nowhere sends the wrong message in climate crisis

By Robert McLachlan

Qantas Airlines’ 7-hour “flight to nowhere”, that sold out in 10 minutes with prices from A$787 to A$3787, seemed like a sick joke to climate advocates. Apart from the waste of fuel and the pointless emissions, passengers would be able to see first-hand, from a plane just like those that carried coronavirus around the world so effectively, the sweeping devastation caused by last summer’s “climate fires” and the global-warming induced bleaching of the Great Barrier Reef. “Would it be more efficient just to crash it in the Great Barrier Reef?” asked Dan Rutherford, aviation director at the International Council for Clean Transportation.

Now a travel enthusiast has suggested that Air New Zealand could follow suit, offering scenic flights of the entire country (not forgetting the Chathams). Actually, New Zealand does have a proud tradition of scenic flights, from small beginnings in the 1930s, to the famous glacier landings that began in the 1950s, to the helicopter flights of today. 

Otago Daily Times, 10 July 1936.The Kotuku was one of three 4-engined De Havilland DH86 biplanes bought by Union Airways the previous year. Union Airways was started by the Union Steam Ship company and later evolved into NAC and then Air New Zealand.

But apart from Air New Zealand’s flights to Antarctica in the 1970s – flights that have continued since then from Australia, and that Qantas is now offering in another of its Boeing 787s, departing from a choice of five cities – New Zealand hasn’t seen anything on this scale.

So why shouldn’t it? After all, if there were customers for an Air New Zealand flight to nowhere, they’d get something that’s valuable to them, and they’d get to help our national flag carrier through some tough times to boot. What’s wrong with that?

What’s wrong is how it looks. Air New Zealand has a fantastic reputation for sustainability. To a hardcore greenie that might sound like a joke, but even seasoned climate campaigner Jonathan Porritt, their chief sustainability advisor, called them ‘the least unsustainable airline in the world’. What’s more, our international tourist industry, which relies on aviation, is largely based around our environmental image – “100% Pure”. Even before the pandemic, many people were pointing out how important it is that that image should be based on reality.

Aviation is important to New Zealand for more than just tourism. It ties families together, it transports students and workers. It’s about the value of transporting people from A to B, not from A to A. On the back of that argument, the global aviation industry has been able to get a golden ticket fostering unlimited growth: air travel doubled in the decade to 2019, and is projected to triple again by 2050. (If that came to pass, aviation would then be using all of the available remaining carbon budget.) The industry has escaped taxes on jet fuel and limits on carbon emissions. There’s not even GST charged on international flights. 

Since Covid-19, the industry has been a recipient of massive bailouts – about $150 billion worldwide, equal to their prior five years of profits. A lot of this government money will be wasted: a study published in May by Joseph Stiglitz and others found that airline bailouts were the very worst of all options on both financial and climate grounds. In New Zealand, the government has so far provided $600 million towards the aviation industry as well as a $900 million loan facility to Air New Zealand.

Somehow a way needs to be found to make a pathway leading towards both financial and environmental sustainability. It could involve less travel – administered through adjustments to charges, landing slots, and/or visas; it could involve investing in synthetic jet fuel. For the tourist industry, it could involve fewer tourists staying for longer. The Tourism Futures Task Force is considering the future of the industry right now, in the context of the ‘Four Capitals’ – economic, environmental, social, and cultural. You can send them your thoughts on this: in such an enormous disruption, the full effect of which hasn’t even begun to be felt, everyone’s voice is needed.

What we don’t need are flights to nowhere.

By Paul Maunder

Late last year I wrote a remake of Waiting for Godot, called Waiting for Greta. The prospect of climate extinction seemed to match the existential angst of Becket’s original (which was perhaps influenced by Hiroshima and the subsequent threat of nuclear holocaust); the Swedish girl had just appeared on the scene and I was impressed by her address to the Climate Change Summit.

Since then, especially since venturing into New York, the heart of the beast, Greta Thunberg has become a prophetic (Naomi Klein’s description) force. Millions of kids have taken to the streets and now workers have been called in to support the movement. She is in the media as much as Trump or Johnson. She addresses parliaments, talks with the Pope, Naomi Klein, Michael Moore, Arnold Schwarzenegger, Obama… and is subjected to the outlandishly intense scrutiny of the modern media and the lunatic babble of social media.

She seems to survive, unfazed. Most of the time she gives the floor to her admirers. When in the midst of her peers she seems shy and marginal. Yet when she speaks the message is crystal clear and very repeatable by others of her generation:

  • We need to listen to the scientists who are telling us that the planet is under extreme threat of warming to the point that human life as we know it will be impossible.
  • Young people and future generations will pay the price. The leaders for the last thirty years, despite knowing the situation, have done nothing. The current leaders remain hesitant or are bent on destruction.
  • The least fortunate in the world will suffer most because rich people hang onto their privilege.
  • Continual economic growth is not the answer. The system has to change. Young people need to take to the streets and make that change.
  • No one is too small to make a difference.

There’s been nothing this clear and succinct since the Communist Manifesto of 1848. And the message is being forged, and the movement led, by this prophetic sixteen year old with Asperger’s.

Both the conservative right and the liberal left try and cut her down to size, either by dismissing her as a hysterical, mentally ill teenager, or by patronising her. Conspiracy theories abound. She’s in the employ of a PR firm. What’s the story with her parents? Some adults must be behind this. She’s a communist figurehead…

But then, she herself increased the intensity when she addressed the UN in New York. She took off the mask to show the anger, grief and pain of a generation. It became a poor theatre moment which created a frenzy. ‘She’s hysterical. She’s making young people anxious and suicidal. Why don’t her parents rein her in?’ For politicians don’t do this, nor do adults when in public. They can pretend anger and abuse one another, but only the mad reveal themselves in this way. Yet, in actual fact, she was on script. Here’s a quote from a book, The Uninhabitable Earth, a story of the future, by David Wallace-Wells:

‘Rhetoric often fails us on climate because the only factually appropriate language is of a kind we’ve been trained, by a buoyant culture of sunny-side-up optimism, to dismiss, categorically, as hyperbole. Here the facts are hysterical and the dimensions of the drama  incomprehensibly large – large enough to enclose not just all of present day humanity but all of our possible futures as well.’

Greta suddenly acted out this enormity (and immediately a Death Metal band turned it into a song). The adults are terrified at being called to account. Is this going to be something like Mao’s cultural revolution? The honest ones, like Michael Moore, are willing to admit failure. Obama? – no wonder he wants to be seen shaking her hand.

Greta’s secret of course is her Asperger’s, which means she doesn’t ‘play the social games you folk are so fond of’, to use her words. She’s focused, obsessed perhaps, sees the issue without compromise, doesn’t chat, remains a vulnerable figure physically. Prophetic because in this situation, to quote Wallace-Wells again, ‘there is no analogy to draw on outside of mythology and theology’.

She is also remarkably astute. In a sweet interview with a Swedish talk show host, safe in her language and culture, she talks about her Papa – she won’t let him go shopping in New York, he’s untidy and probably sick of having to follow her around (having to pick her up from the UN rather than the school disco). She will keep assessing the public exposure and withdraw if it gets too much. I’m sure she’ll be capable of disappearing for a while just as effectively as she appeared. And she’ll have a remarkable knowledge of the way the political world works.

So far she has survived the maelstrom of the Empire. After all, it’s nothing compared to what the planet’s going to throw at us. And to copy her in three simple ways would change the world: stop flying, stop stupid shopping and become vegan. Let the whole human race do that, starting tomorrow. Whew! Yet it is possible. That’s the point she’s making.

How the law can help in the fight for climate action

By Jenny Cooper

Jenny Cooper QC is a New Zealand corporate lawyer and president of Lawyers for Climate Action NZ. She spoke on 10 August 2020 at “All aboard! The race to decarbonise Auckland’s transport.”

All decision-makers who are exercising any form of public power have to act lawfully. That includes cabinet ministers, ministries, councils, and statutory bodies like the New Zealand Transport Authority. If they make decisions that aren’t consistent with the law or with their statutory powers, then anyone affected can apply to the court for judicial review to determine if the decisions are legal or not.

Decisions can be found to be unlawful if they are outside the scope of the decision-maker’s legal powers or lawful purpose under the relevant Act; if irrelevant considerations were taken into account, or mandatory considerations were not taken into account; if they are unreasonable or irrational; or if they have been affected by bias.

Often, an Act will spell out the considerations that a decision-maker must take into account, but, in addition, a court may find that some things which are not explicitly referred to are so obviously relevant that they should have been taken into account.

The usual result of a decision being found to be unlawful is to render it invalid and of no effect. The court will typically ask the decision-makers to do their work again, lawfully this time.

What is clear is that both in New Zealand and overseas, the courts are increasingly willing to get involved in decisions relating to climate change. This was the case in Thomson v Minister for Climate Change. Sarah Thomson challenged the failure by the then-Minister for Climate Change to review New Zealand’s Nationally Determined Contribution under the Paris Agreement. The court was willing to get involved and did find that there were problems with the decision, but that since the government had recently changed, there was no need to order a review.

In New Zealand, sources of the legal duty to decarbonise lie in international and domestic law, and in Te Tiriti o Waitangi.

International law

International law, such as the Paris Agreement, is not directly enforceable in New Zealand courts. But courts do interpret domestic law in a manner consistent with international obligations where possible, for example in Helu v Immigration and Protection Tribunal (see paragraphs 143-145 of the decision). International obligations can also be found to be mandatory considerations for decision-makers. The best recent example is the Heathrow runway case from the UK. In R Plan B v Secretary of State for Transport, the court found that even though the Minister had no statutory obligation to consider the Paris Agreement in approving the third runway, “There can be some unincorporated international obligations that are so obviously material [to a decision] that they must be taken into account. The Paris Agreement fell into this category.” This was an incredibly powerful lawsuit and an incredibly powerful finding by the court.

Domestic law

The centrepiece of New Zealand’s climate law is the Climate Change Response Act 2002, amended in 2019 (the “Zero Carbon Act”). All powers under the Act must be exercised in a manner consistent with its purposes, which include contributing to the global effort under the Paris Agreement to limit global warming to 1.5ºC.

Section 5ZN permits all public decision-makers to take the 2050 zero carbon target and national carbon budgets into account in performing a public function, power, or duty. During deliberations over the bill, Lawyers for Climate Action NZ argued that the subsequent clause (which said that there could be no legal remedy if the 2050 target or carbon budgets were not taken into account) should be deleted. We argued that the courts must have the power to determine the appropriate remedy if the decision-makers are not taking the right things into account, and this was accepted.

On this basis, Lawyers for Climate Action NZ hold the view that the 1.5ºC target, the 2050 target, and the carbon budgets are so obviously material to decisions in some areas, like the transport system, that they must be taken into account. We’re looking forward to testing this in court, if necessary!

There are also many Acts that govern local government and the regulations applying to various polluting activities. For example, the Local Government Act provides a legal duty to “promote the social, economic, environmental, and cultural well-being of communities in the present and for the future”, and to “maintain and enhance the quality of the environment”; the transport system must be “in the public interest”. A transport system pumping out ever-increasing amounts of greenhouse gases simply cannot be in the public interest.

The right to life

Urgenda is a civil society group in the Netherlands, active on climate issues. For several years they have been arguing in the Dutch courts that the Dutch government’s efforts to cut emissions are insufficient: specifically, that they were not consistent with 1.5ºC and that therefore they are not consistent with the right to life, because climate change creates a foreseeable risk of loss of life. On 20 December 2019 the Dutch Supreme Court agreed

Like the European Convention on Human Rights on which this case depended, the New Zealand Bill of Rights includes a right to life. Lawyers for Climate Action NZ argue that a similar positive legal obligation also applies in New Zealand and that decisions inconsistent with protection of the right to life are unlawful.

Te Tiriti o Waitangi

Article 2 of Te Tiriti o Waitangi protects Māori tino rangatiratanga over Māori whenua, kāinga, and taonga, which extends to climate and the environment.

In 2013, the Supreme Court in NZ Māori Council v Attorney General held that Te Tiriti imposed a duty on the Crown to actively protect Māori use of their lands and waters to the fullest extent practicable.

The Waitangi Tribunal, in Wai 262, found that Te Tiriti imposes a duty of active protection of the environment and a duty to recognize the continuing role of Māori as kaitiaki of environmental taonga.

Two claims are pending, one in the Waitangi Tribunal (Wai 2607) and one in the High Court (Smith v Attorney General) alleging breaches of the Crown’s obligation to take positive action to protect Māori against the threat of climate change. 

To sum up, Lawyers for Climate Action NZ hold that Ministers must take our obligation under the Paris Agreement to pursue efforts to limit global warming to 1.5ºC into account; that they must comply with the Crown’s obligation to Māori under Te Tiriti to protect against climate change; that they must take into account the 2050 target and successive carbon budgets, as set out in the Zero Carbon Act; and that they must act consistently with the right to life. Failure to do so will make their decisions unlawful.

Climate explained: are we doomed if we don’t manage to curb emissions by 2030?

By Robert McLachlan

A reader asks: Is humanity doomed? If in 2030 we have not reduced emissions in a way that means we stay under say 2℃ (I’ve frankly given up on 1.5℃), are we doomed then?

Humanity is not doomed, not now or even in a worst-case scenario in 2030. But avoiding doom — either the end or widespread collapse of civilisation — is setting a pretty low bar. We can aim much higher than that without shying away from reality.

It’s right to focus on global warming of 1.5℃ and 2℃ in the first instance. The many manifestations of climate change — including heat waves, droughts, water stress, more intense storms, wildfires, mass extinction and warming oceans — all get progressively worse as the temperature rises.

Climate scientist Michael Mann uses the metaphor of walking into an increasingly dense minefield.

Good reasons not to give up just yet

The Intergovernmental Panel on Climate Change described the effects of a 1.5℃ increase in average temperatures in a special report last year. They are also nicely summarised in an article about why global temperatures matter, produced by NASA.

The global average temperature is currently about 1.2℃ higher than what it was at the time of the Industrial Revolution, some 250 years ago. We are already witnessing localised impacts, including the widespread coral bleaching on Australia’s Great Barrier Reef.

Limiting warming to 1.5℃ requires cutting global emissions by 7.6% each year this decade. This does sound difficult, but there are reasons for optimism.

First, it’s possible technically and economically. For example, the use of wind and solar power has grown exponentially in the past decade, and their prices have plummeted to the point where they are now among the cheapest sources of electricity. Some areas, including energy storage and industrial processes such as steel and cement manufacture, still need further research and a drop in price (or higher carbon prices).

Second, it’s possible politically. Partly in response to the Paris Agreement, a growing number of countries have adopted stronger targets. Twenty countries and regions (including New Zealand and the European Union) are now targeting net zero emissions by 2050 or earlier.

A recent example of striking progress comes from Ireland – a country with a similar emissions profile to New Zealand. The incoming coalition’s “programme for government” includes emission cuts of 7% per year and a reduction by half by 2030.

Third, it’s possible socially. Since 2019, we have seen the massive growth of the School Strike 4 Climate movement and an increase in fossil fuel divestment. Several media organisations, including The Conversation, have made a commitment to evidence-based coverage of climate change and calls for a Green New Deal are coming from a range of political parties, especially in the US and Europe.

There is also a growing understanding that to ensure a safe future we need to consume less overall. If these trends continue, then I believe we can still stay below 1.5℃.

The pessimist perspective

Now suppose we don’t manage that. It’s 2030 and emissions have only fallen a little bit. We’re staring at 2℃ in the second half of the century.

At 2℃ of warming, we could expect to lose more than 90% of our coral reefs. Insects and plants would be at higher risk of extinction, and the number of dangerously hot days would increase rapidly.

The challenges would be exacerbated and we would have new issues to consider. First, under the “shifting baseline” phenomenon — essentially a failure to notice slow change and to value what is already lost — people might discount the damage already done. Continuously worsening conditions might become the new normal.

Second, climate impacts such as mass migration could lead to a rise of nationalism and make international cooperation harder. And third, we could begin to pass unpredictable “tipping points” in the Earth system. For example, warming of more than 2°C could set off widespread melting in Antarctica, which in turn would contribute to sea level rise.

But true doom-mongers tend to assume a worst-case scenario on virtually every area of uncertainty. It is important to remember that such scenarios are not very likely.

While bad, this 2030 scenario doesn’t add up to doom — and it certainly doesn’t change the need to move away from fossil fuels to low-carbon options
