Banning permanent pine forests from the NZETS will at least double carbon prices and further impoverish Maori

 


Comment on MPI Policy Proposal: "Managing exotic afforestation forestry incentives"- proposal to change forestry incentives in the NZETS

Clients have asked us for comment on the new MPI policy document “Managing exotic forestry afforestation incentives” in the NZETS, released yesterday. It is proposed that pine (Pinus radiata) forest be excluded from the permanent forest category in the ETS.

We consider that it is unlikely that this policy change will happen for the following reasons:

 

1)      Permanent carbon pine forest supplies the NZETS with over 90% of its carbon credits. The assertion in the press release that the proliferation of permanent pine forest will result in lower long-term carbon prices is simply incorrect – the laws of supply and demand will prevail. If the Government cuts off over 90% of the future supply of credits, the credit price will at least double, NZ's carbon bill to the UN will go up, and NZ will be further exposed to proposed carbon tariffs on our exports to the EU and USA.

 

2)      The press release also asserts that “an increase in native forestry will require additional management efforts to eliminate pests that feed on native trees”. Is the Government seriously suggesting that we should stop planting native forests because we can’t control goats, possums, hares, rabbits, pigs and deer? We have seen numerous examples where native forest has been replanted and pests controlled successfully.

 3)      Native forest should be replanted wherever practical because of its contribution to water and soil conservation values and biodiversity, but unfortunately it doesn’t pack on substantial carbon for about 500 years, so it won’t help NZ’s carbon balance in the short term. Nevertheless, at current carbon prices, young native yields about $500 per hectare per year.

 4)      However, if the carbon price doubles, native forest will be worth about $1,000 per hectare per year, and exotic hardwoods even more (they store carbon at about 80% of the rate of pine), so people will plant these.

 5)      Pine forests are not the terrible environmental villains suggested in the policy paper, and they will not march across the land and drive us all into the sea. Negative environmental impacts happen mostly when harvesting, and that is due to poor logging practice by the people, not by the trees. NZ’s carbon forestry estate is only about 350,000 hectares, 3% of rural land area. It is being added to at a rate of about 12,000 hectares per year. At that rate it would take 833 years for carbon forest to occupy all the farm land in NZ. However 88% of ETS forest is on hard country – Class 6-8, which produces very little any other way. Obviously farm owners are not bent on converting their entire farms to carbon forestry holus bolus. Our advice is to plant your hard country in carbon forest – and this is what farmers are doing. It is entirely specious and misleading to claim carbon forestry is seriously threatening the agricultural industry in NZ.

 6)      If pine trees really are the terrible environmental villains as suggested, then to be consistent the Government should ban all replanting and establishment of old and new commercial pine forests as well. This would put 35,000 people out of work, reduce NZ’s export sales by $6.2 billion, and we’d have to import almost all of our wood products for building and construction. We have no estimate of what that would do to house prices. Others may have.

 7)      If farms are being sold to overseas buyers for carbon farming or commercial forestry, that is not the NZETS’s fault. The policy settings for such purchases are a matter for the Overseas Investment Office, not MPI or the NZEPA. As an aside, foreign forest companies are NZ’s biggest landowners, so the horse has already bolted. Changes to OIO policy are the solution here, not changes to the NZETS.

 8)      The social impacts of carbon forest allegedly depopulating rural areas are vastly overstated. The Ministry of Education has informed us that they have never closed a rural school because carbon pine tree establishment has caused rural depopulation. School closures, and openings, occur according to a group of socio-economic factors, not just one.

 9)      Carbon forestry is a godsend particularly for hill country farmers who, up until recently, haven’t been able to earn a living off their hard country. We have seen farmers finally getting a decent return for their work, with retirement looking a lot brighter. We have also seen carbon revenue being used to buy more beef stock and a new dairy unit. Paying for the daughter’s wedding is also a lot easier.

 10)   This policy will hit Maoridom the hardest. Every single one of our iwi clients has substantial hard hill country resource which has effectively produced nothing for over 100 years. There are very large areas where carbon forestry using the right mixture of pines and native forest re-establishment will literally lift whole whanau out of practical poverty. Practical poverty is where you can afford your Weetbix, but you have no money to offer your tamariki a university education or your kaumatua and kuia decent housing in their old age. More funding should be put into iwi-based carbon farming. Currently Te Puni Kokiri will fund carbon farming feasibility reports, but it won’t fund planting or carbon farm management. So there’s no point doing the feasibility report. Instead, iwi with large carbon farming potential but who lack development funding and management skills are exposed to unscrupulous operators who will place a contractual liability on the land and take the lion’s share of the carbon revenue.


Hopefully this proposed policy will be consigned to the dust bin of history where it belongs. This is the 21st Century, not the 19th Century. We need to pursue carbon negative futures for our country and our whanau, and take the opportunity that trees (of all species) offer to make that happen.

New Zealand Government Supercharges Emissions Trading Scheme with Huge Increases in Carbon Credit Values Proposed for 2020


Yesterday the New Zealand Government released its proposals for reforming the price settings on the NZ Emissions Trading Scheme in 2020.

Major changes to pricing levels are proposed, see Figure 3 above.

These price control changes will act to "supercharge" the NZETS, as the price ceiling will be set at $50, the Government fixed price option will go to $35, and there will be a price floor of $20.

This potentially increases carbon credit values by 140%-200%.

There will also be a price effect on rural forestry land values - we are working on what this increase might be with associates in the rural property sector.

Consultation closes on 28 February 2020, with legislation changes proposed in mid 2020.

This morning the NZ carbon market has reacted by not trading NZU futures contracts.

We will be separately contacting our clients to advise on how the market is reacting, and how much more we calculate their carbon portfolio may be worth in 2020.

Good news for those foresters with trees in the ground registered in the NZETS!  More needed!

We are very pleased that our advice on future NZETS structures and price trends has proved accurate (!).

We are now analysing other parts of Government NZETS and Zero Carbon Bill announcements, and we will be incorporating the proposed changes in our MyCarbon computer model of yields, risks and revenues from the carbon business.

Methane emissions from farm animals a 'green herring' in New Zealand

Photograph: Cattle belch monitoring, Moorepark, Ireland 2010

A recent article in The Guardian reports that climate change denial is changing tack from outright denial to a clever 'deflection' campaign.  This focuses on making individuals feel guilty about their food and travel choices, and then descends into 'doomism', which leads to hopelessness and inaction.  In this way, society is misled into failing to deal with the main cause of climate change - fossil fuel use.

Global greenhouse gas (GHG) sources are usually quoted at around 70% from fossil fuel use (energy production), agriculture 24%, industry, buildings and waste disposal the remaining 6%.  

New Zealand's GHG profile is quite different from the global profile, with energy production 41%, agriculture 48% (sourced mainly from animals belching methane), industry and waste 11%.

Recently the issue of methane emissions from farm animals has been controversial in New Zealand. The Agriculture sector has pointed out that methane is a short-lived GHG (about 14 years), while others have countered that it has a high Global Warming Potential (GWP), 25 times stronger than carbon dioxide.  The New Zealand Government has agreed to the sector's proposal to leave agriculture out of the New Zealand Emissions Trading Scheme until 2025, giving the sector until 2022 to come up with methods for reducing farm emissions.  

One way to reduce farm emissions is to reduce the number of animals farmed.  Leaving aside land use stocking and water quality issues, it would seem extraordinary that a food producing nation would be asked to consider reducing its production levels in a world that needs more food, not less.  And this from a pasture-based farming system in New Zealand that has a much lower overall environmental footprint (GHG plus everything else) and animal welfare footprint than barn-based intensive stock feeding regimes overseas.

So are methane emissions from farm animals really a problem locally or globally, compared to fossil fuel emissions?  Take a quick look across the latest science and we find:
  • Globally methane is 16% of all GHG;
  • Methane disappears from the atmosphere in about 14 years;
  • Modelling of methane's global warming effects from 1900 show a small decline relative to carbon dioxide;
  • World methane emissions have increased about 25% from 2005-2018.  This is thought to be from frozen wetlands melting (as the northern hemisphere warms), natural gas production, and livestock, although the global cattle population has increased only 0.6% in that time;
  • Fossil-fuel sourced carbon dioxide is about 80% of all GHG;
  • Carbon dioxide takes 20-200+ years to transit out of the atmosphere;
  • Recent studies show fossil-fuel sourced carbon dioxide is now about 86-87% of global carbon dioxide emissions; 
  • World fossil-fuel sourced carbon dioxide increased 50% from 1990-2015, increases in India (7.2%), Russia (3.5%), China  (2.9%) and the USA (1.5%); and,  
  • Emissions from New Zealand Agriculture 1990-2017 rose 13.5%, due to a near doubling of the dairy herd and 650% increase in use of nitrogen fertiliser. New Zealand's cattle population is about 0.1% of the global cattle population. 

There are some significant changes to note:

(1) Fossil-fuel sourced carbon dioxide sources have increased to 87% of global carbon emissions in the last ten years, so that they almost completely dominate the global GHG cycle;
(2) Global methane emissions over time have had no impact compared to fossil-fuel sourced carbon dioxide (so far);
(3) Global methane emissions are recently up from permafrost melting and natural gas production;
(4) Globally, New Zealand's cattle populations and their emissions do not register at all on any statistic; and,
(5) Local increases in New Zealand's dairy herd and their emissions have impact in New Zealand alone.

And so what to conclude?

Methane emissions from pasture-based farm animals are a "green herring" in New Zealand, and most probably globally.  

The reduction and reversal of global warming depends almost entirely upon reducing fossil fuel use.  Switch away from fossil fuels and the job is mostly done.  Reducing animal farming in New Zealand will make absolutely no difference to world GHG levels, and would be a pointless exercise in climate guilt.  Another 'deflection' away from dealing with the real problem.

Because of the structure of the Paris Climate Agreement and New Zealand's unusual GHG profile, the nation could be held fiscally responsible for methane emissions that are just a very few cattle breaths in reality, with no global impact.  There could, however, be a very high impact on the nation's pocket if the situation isn't shrewdly managed.  

And one wonders...how many more green herrings are out there?

Independent Climate Commission Gives New Zealand Opportunity to be Number One Again

The new Labour - NZ First - Green Party Coalition Government's proposal to call an Independent Commission on Climate Change provides the country with an unmissable opportunity to make New Zealand Number One again in innovation, with a 21st Century approach to climate change management and economic and social development.
 
You can't get away from the science. Climate change is happening, and it's happening faster than we first thought.  The Australians have a very scary climate model  - scary because it's so accurate.  Twelve years ago at an Australian Transport Conference, they showed their model with Arctic and Antarctica ice melt, and sea level rise predictions based on various warming scenarios.  Twiddle the scenario and you get certain predictions.  Based on the climate science back then, you weren't supposed to be able to sail through an ice-free Arctic or see very major parts of Antarctica break off until about 2040.
 
But these things are happening now - 25 years ahead of that prediction.  The interesting thing then was that if you twiddled the model inputs to match the global warming data we have now, then the Aussie's model pulled back 20 years to put Arctic and Antarctica ice melt, and accelerating sea level rise into the 2015-2025 time frame we are seeing now.  Not bad for a bunch of cricket players. 
 
The work that our own scientists are doing, especially in Antarctica, is invaluable in refining these predictions through the NZ Sea Level Rise Programme.  Hopefully the new political atmosphere will encourage all the parties involved to work together on a National Climate Change Response Strategy that gives the people of New Zealand sound, practical advice on how to plan for the changes that will happen over the next 50-100 year timeframe.  A stitch in time saves nine.
 
It will also provide us with the opportunity to fix our fundamentally flawed Emissions Trading Scheme (ETS).  Everybody needs to be "in", because this issue is quite literally everybody's problem for those of us who recognise that we live on Planet Earth, and we have to go by her rules.  If we are smart enough to design an "all in" ETS with the right policy levers, international linkages, massive tree planting programme (which doesn't have to be on prime agricultural land - there are plenty of "badlands" needing planting), and effective carbon trading rules, it will drive us into Carbon Negative territory.  Then we will have a Great Story to tell. 
 
And by the way, Carbon Zero isn't quite enough.  That concept is something of an academic "will-o-the-wisp".  You could argue forever over which scientific technique (aka magic wand) should be used to define "Carbon Zero".  There will always be an assumption, a flaw, an error limit, or an uncertainty that will cast serious doubt on the postulated "Carbon Zero" position. 
 
Don't pay our scientists to argue about that red herring in front of courts and tribunals.  The reality is that there's already so much greenhouse gas in the atmosphere we need to figure out ways to suck the damn stuff up.  That's where the electric cars and massive tree planting programme come in. Pay the scientists to figure out more ways to get rid of the stuff - or at least issue them all with a spade and a box of trees to plant.  Every week.
 
Then, we will have a Great Story to tell the world: Responsible Carbon Management, Carbon Negative Export Products, a World-Leading ETS, and a good and great heritage for our children and grand-children.  Carbon Negative New Zealand.

New Zealand Needs To Grab Every Carbon Credit It Can


The Parliamentary Commissioner for the Environment’s recent report on agricultural greenhouse gas emissions highlights the need for agriculture to make meaningful progress in reducing its emissions.  In New Zealand this is particularly important because agriculture is responsible for 48% of our emissions. 

The Commissioner’s report follows disturbing analysis from the Ministry for the Environment, where a senior official this week advised that meeting New Zealand’s Paris Climate Agreement pledge could cost the country more than $70 billion, and see carbon prices rise to $300 a tonne if we are not part of international carbon markets.



New Zealand’s Emissions Trading Scheme is greatly weakened because it is not linked to international carbon markets, and because it covers only half of our emissions.  Hopefully the current Government review of the ETS will address these issues, especially since the Paris Agreement comes into force on 4 November, and the next UN meeting on international climate change action is set down for Marrakech in two weeks’ time.
The Commissioner recommends planting trees to offset emissions.  This is an easy and relatively cheap strategy to pursue, with multiple benefits for agriculture - including riparian and erosion protection, water quality improvement, stumpage, and issue of NZU carbon credits for qualifying blocks.  Managed well, tree planting creates more income for farmers.




New Zealand needs to encourage farmers and other land owners to plant more trees, and grab every carbon credit we can.  We need to pursue a vigorous national planting programme and aim to become the world’s first Carbon Negative Country.  This way we will reduce the risk of being in serious carbon debt in future, and create an ETS that is an asset, not a liability for the nation.

GreenXperts Limited and Green Tick Certification Limited are working to maximise the benefits of carbon trading for New Zealanders, by launching this week a $10 million Certified Carbon Credit Fund.  We have already had local interest, and inquiries from Europe and India.  We look forward to being part of the next phase in positive climate change action – helping New Zealanders to grab every carbon credit they can.

The Mysterious Case of Disappearing Pipi at Mair Bank, and Potential Impacts on Marsden Point’s Stability



First published in the Whangarei Heads Newsletter, Feb-March 2015

 
Source: Pawley 2014

Massive reduction in pipi numbers since 2005
The latest scientific reports from the Northland Regional Council (NRC) and the Ministry for Primary Industries (MPI) show a massive 99.3% drop in both pipi biomass (by tonne) and abundance (by numbers), and two successive ‘recruitment failures’ (juveniles not achieving breeding age) on Mair Bank over the past ten years.  Only 63 individual pipi of any size were found in 140 sample sites during the February 2014 survey.  These grim findings led MPI to impose a total ban on pipi harvesting from October 2014 onward.

Potential impacts upon Marsden Point’s stability
It has been acknowledged by authorities for over 30 years that the layers of old pipi shells and live pipis on Mair Bank armour and stabilise the Whangarei Harbour entrance and Marsden Point.  In 1983 it was estimated that the pipi banks were equivalent to at least $4 billion (2014 value) in harbour works.  Should the pipi banks be compromised, then there could be impacts upon the stability of Marsden Point and its associated facilities.

Possible causes of pipi disappearance
Possible causes of pipi disappearance could include: climate change (changes in currents and water acidity); Mair Bank movement (reducing habitable area); contaminants in the water and/or sediment (causing pipi to depart Mair Bank and perish in deeper colder waters, and/or recruitment failure); and selective removal of the breeding population (the larger pipi) by pipi pickers.  There is probably a combination of causes, but at present there is insufficient evidence to determine what has happened.  The latest scientific reports comment that the available information has not been collected in a consistent or comprehensive manner, making it difficult for scientists to pin down causes, assess risks, or propose remedies.

What the authorities are doing
NRC is the coastal marine area authority, and MPI the fisheries authority.  Several reports have been commissioned and discussed with stakeholders by both NRC and MPI.  Currently there seems to be a hiatus in activity following the sobering results of the 2014 survey and the institution of the total ban. 

Questions that need answering
A number of important questions need answering.  What has happened since 2005 to cause the pipi to die?  Can pipi die-out be remedied?  Will the disappearance of the pipi endanger the stability of Marsden Point, and if so, when, under what conditions, and what can be done about it?  Will the total ban on pipi picking rebuild the pipi population, or is more action needed?  What effects will Northport’s proposed deepening of the harbour channel have upon the integrity of Mair Bank and Marsden Bank?

The Whangarei Harbour and Marsden Point are valuable national assets worth billions of dollars.  The disappearance of the pipi that stabilise the harbour entrance is a national issue that affects us all, and one that must be addressed competently.  Current information is patchy, incomplete and inconclusive.  A properly scoped and adequately funded Mair Bank Sustainable Management and Recovery Plan needs to be commissioned immediately by MPI as lead authority, supported by all the stakeholders involved.  It will be interesting to see what the next steps will be by the authorities responsible for the sustainable management of the Whangarei Harbour and its priceless pipi.
