Environment Aotearoa 2015 omits NZ's greenhouse gas growth trend

The Ministry for the Environment and the Statistics Department jointly released the new state of the environment report Environment Aotearoa 2015 today.

The press release for the co-produced report, promises quite a lot.

Government Statistician Liz MacPherson said the report gives a clear and independent overview, based on the best-quality information available.
Ms MacPherson said the report uses robust data from hundreds of sources, and follows international best practice for environmental reporting. “We would like to improve the data for future reports, and we are working on this,”
"The report is supported by interactive web pages containing trend and regional data. I would encourage people to take a look at the areas they are interested in.”

Wow! Interactive web pages containing trend and regional data! How could I resist the temptation to look for some interactive graphs of greenhouse gas emissions! And to compare their graphs with my graphs.

I browsed on through the 'Atmosphere and Climate' domain to the page for Global greenhouse gas emissions and found only...information on global greenhouse gas emissions. And a factoid that could have culled from any speech by Tim Groser or Nick Smith.

Between 1990 and 2011, New Zealand emitted an average of 0.1 percent of global net GHG emissions.

I tried again at the page Greenhouse gas concentrations. This page reported concentrations of greenhouse gas emissions recorded at Baring Head. Interesting but still no national emissions data.

However, i did find a widget enabling the embedding of a graph the Baring Head atmospheric carbon dioxide data record.

Nowhere from anywhere within the Te Taiao Aotearoa environmental indicator web pages could I find any mention of New Zealand's gross and net greenhouse gas emissions.

I resorted to doing a search of the Statistics website for greenhouse gases. That did turn up a web page showing New Zealand's greenhouse gases. That page clearly reported the trend with a prominent red cross.

Negative change. New Zealand’s net greenhouse gas emissions have increased 42 percent since 1990. New Zealand’s net greenhouse gas emissions increased 42 percent between 1990 and 2013. Total emissions increased 21 percent.

Another widget for embedding. A very plain graph. It uses a different greenhouse gas inventory report published earlier this year from my graphs for 1900 to 2012. The data for 1990 to 2013 uses a different way of calculating the carbon dioxide equivalent values for methane. This increases the year by year values by several million tonnes per year.

Still it just seems so bizarre to have statutory environmental indicators and to not include our national production of greenhouse gases. Especially since Statistics already had the data on it's web page. They need only to have put the link in. Is this cognitive dissonance, self-censorship or climate silence?

New Zealand Gross & Net Greenhouse Gas Emissions 1990 to 2012

I have just prepared and revised a graph of New Zealand's gross and net greenhouse gas emissions for the years 1990 to 2012. I have recycled the style of the graph of gross emissions from 1861 to 2012.

NZ-ghg-2012-720by540

I have used html code from the scalable vector graphic I uploaded to Wikipedia Commons and not the Blogger template. I think it gives a better quality graphic.

The data is from Ministry for the Environment publication New Zealand’s Greenhouse Gas Inventory 1990 – 2012, Report ME 1148, ISBN 978-0-478-41242-0, April 2014.

The data and R programming language script are available at Wikimedia Commons.

How I made the graph of NZ gross greenhouse gas emissions

Yes another post about my new line chart of gross greenhouse gas emissions in New Zealand. I have just uploaded a SVG version to Wikimedia Commons. On that page there is a link to the data source on Robbie Andrew's website and the background to the data and it's use in a publication.

The scaled vector graphic looks like this when the suggested template from Wikimedia is used.NZ Gross GhG Emissions 1861 to 2012

And I have uploaded the R script I wrote to Google Drive

Did anyone sign the Kyoto Protocol in good faith? The Kyoto Escalator shows that New Zealand certainly didn't

Robin Johnson's Economics Web Page introduces the Kyoto Escalator chart and argues that New Zealand was just as complicit as the major European countries in negotiating the Kyoto Protocol so that they complied with it without reducing either gross or net emissions.

Kyoto Escalator
New Zealand's Gross greenhouse gas emissions (blue) net emissions (brown) and 'Kyoto' emissions (red) 1990 to 2012. Double click on the chart to see it at 100% and in good resolution.

Professor Dave Frame is the new director of the Climate Change Research Institute at Victoria University of Wellington. He is a University of Canterbury-trained scientist who has worked for some years in Britain. He has just joined the climate change fray with a very interesting opinion editorial "International focus needed over climate" in the Dominion Post. Welcome to climate change issues back in New Zealand, David.

David Frame writes that New Zealand does not want to be thought of as the country that reneges on international treaties.

"Reputationally, accepting commitments and then failing to deliver on them is not a look New Zealand likes. "Doesn't honour the treaties it's signed" is not one of the few sentences we want people to remember about us."

So, yes, I agree, New Zealand should honour the treaties it signs. I hate to nitpick but, isn't New Zealand the country that was explicitly founded in 1840 on a treaty that was not honoured?

David Frame describes the history of the Kyoto Protocol climate negotiations

"...the Kyoto Protocol was a no-win situation for places like New Zealand. In the 1990s Britain and Germany were reducing their emissions of greenhouse gases for non-climate-related reasons (declining manufacturing and the collapse of the coal industry in Britain; technological substitution in the case of post-reunification Germany)."
"Kyoto's structure, reductions of emissions by some specific fraction compared with 1990 levels, were designed with this in mind, since it allowed Europe to appear to "take the lead" without actually doing anything very different from what they were going to do anyway. It was an approach so clearly aligned with the near-term reputational interests of some stakeholders that the Nobel prize-winning strategist Tom Schelling wrote of it: 'I cannot help believing that adoption of such a commitment is an indication of insincerity'."

Frame believes New Zealand's negotiators were innocent parties who acquiesced in these machinations while Britain and Germany portrayed themselves as "leaders" on climate change, even though their emissions reductions basically consisted of doing what they were going to do anyway.

While I am a little disappointed that Britain and Germany acted in such a self-serving way, I don't doubt that David Frame is correct about their motives. However, I don't think he is correct to say New Zealand was innocent. On 31 October 2007, the then Minister of Climate Change Simon Upton gave a speech about New Zealand's negotiating position three weeks before the UNFCCC meeting in Kyoto.

Upton stated that within New Zealand's negotiating position, using forest sinks to offset increases in emissions was just as important as the Protocol including international emissions trading, an all-gases approach and prompt acceptance of commitments by developed countries.

"Sequestration of carbon in sinks (such as forests) should qualify alongside emission reductions for the purposes of counting progress towards any targets that are agreed."

Upton contines.

"I want to say why sinks are important - spelling out in broad terms the economic benefits to New Zealand of counting sinks - and explain briefly how New Zealand considers they ought to be treated. Then I want to say why - even though the correct treatment of sinks is both fair in terms of the Convention, and good for New Zealand's economy - sinks nevertheless do not and cannot protect New Zealand emitters of greenhouse gases from adjustment."
"Adding to carbon stocks through afforestation should count positively; reducing stocks (through forest harvest, land clearance and such like) should count negatively."
"If - and I emphasise if - sequestration is treated in the way New Zealand has long been advocating, then the major contribution we expect to make to removing carbon from the atmosphere in future years will earn us 'credits'."

Upton and the New Zealand negotiators got what they wanted. Forest carbon sink credits were included as offsets. However, Upton provided several cautionary notes. If NZ's forest carbon credits were recognised in Kyoto, it may be perceived as special pleading. Also fairness suggested that forest owners should receive them, and be able to sell them. As opposed to the Government keeping them for compliance with Kyoto.

"New Zealand's stance on sinks has been treated with scepticism by some because, superficially, it looks as though it may be special pleading by New Zealand to take advantage of our sinks to reduce the pressure on emitters to make adjustments. We do not see it that way. New Zealand has been clear in responding to other countries that we do not see the accrual of sink credits as a way to insulate New Zealand from acting to reduce emissions. We see New Zealand's sink credits being an integral part of the international emission trading market. As such, we see New Zealand emitters facing the world price for carbon emissions provided that price is generated by a free market in emission permits."
"Let me now turn to a related question: why recognition of sinks nevertheless does not and cannot protect New Zealand emitters of greenhouse gases from adjustment. It might be suggested that New Zealand's interest in sinks stems purely from a desire to secure for itself a large buffer that would allow for significant growth in greenhouse gas emissions. That is not the case -- nor do I believe would it be credible to pursue such an objective."
"It would simply not be credible to advocate least cost tradeable mechanisms for the world and then seek to keep New Zealand's forest credits for domestic use only. Sequestration credits should accrue to the forest growers who earn them, and they should be free to place them on the world market."

So Simon Upton foresaw two problems with using the credits from forest carbon sequestration as a buffer to allow growth of GHG emissions. There was the reputational problem of New Zealand's insincere negotiating position in the Kyoto discussions. And there was the problem that the credits should accrue to the owners of the forests, not the Government.

New Zealand's climate change officials solved the "who's credits?" problem by inventing a new 'junk' currency to be issued to the commercial foresters instead of Kyoto units (and to buy off greedy emitters); the New Zealand Unit. The real Kyoto forest carbon removal units were kept "off the balance sheet". In the New Zealand Greenhouse Gas Inventory 1990 2009 and in the Kyoto Protocol net position report, the carbon sequestration from 2008 to 2012 is estimated from forest surveys. The actual Kyoto removal units will not be recognised until after 2012. It is these as-yet unissued units that offset the 19% increase in New Zealand's gross GHG emissions since 1990.

It seems since Simon Upton's time, we have developed collective amnesia about intentionally negotiating the Kyoto Protocol so that we could rely on forest carbon sinks to buffer increases in greenhouse gases. Has any one of the Kyoto Protocol parties negotiated and acted in good faith? New Zealand certainly hasn't

The Science is Clear - new James Hansen talk from TED 2012

I have just found this recent 2012 TED talk by James Hansen. It has been on-line since 7 March. The number of views on TED is 120,748 today. The number of views on Youtube was 13,473. I bet that rises.



The talk is very polished. Hansen reads from a script and has obviously run through the talk several times. Hansen discusses the natural greenhouse effect, the Earth's energy imbalance caused primarily by fossil fuel combustion, sea-level rise, species extinctions, impacts on agriculture and the need to act for the benefit of future generations as represented by his grandchildren.

Estimated historical emissions vs future IPCC scenarios--how ... on Twitpic

Michael Tobis discusses poor media coverage of the highest annual emissions of greenhouses gas ever. He asks why can't the media explain using some good charts?

Here's a chart comparing actual emissions of carbon with various predictions from the IPCC Fourth Assessment Report of 2007.

Smith's Gross Error on Net 1990 GHG emissions

Speaking of gross Kyoto confusion, Nick Smith has leapt in to the media fray to defend his view of the Kyoto Protocol and to say that the Greens Russell Norman has got his numbers wrong in his press release.

Smith says Norman is wrong and "tricky, misleading and mischievous" to say that net 1990 emissions are 31 million tonnes less than gross 1990 emissions. Smith says the difference is 1 million tonnes.

Unfortunately it is Smith that has made the Gross error.

In the forth paragraph, Smith states:
New Zealand’s emissions in 1990 were 60.9 million tonnes gross and 61.7 million tonnes net under the agreed Kyoto Protocol rules.
Umm no, according to MfE (April 2010) New Zealand’s Greenhouse Gas Inventory 1990–2008, Report No ME 1009, by the Ministry for the Environment, ISSN 1179-223X.

Page iv states "In 1990, New Zealand’s total (or gross) greenhouse gas emissions were 60,773.6 Gg carbon dioxide equivalent (CO2-e)". (60.7 million tonnes)

Page v states "In 1990, New Zealand’s net greenhouse gas emissions were 29,707.3 Gg CO2-e." (29.7 million tonnes, and certainly not 61.7 million tonnes as Smith's release states)

(NB Gg = gigagrams and 1000 Gg = 1 million tonnes)

Here's the chart again! Nick Smith, have a good look at where the green and blue lines leave the lefthand vertical axis!



Does the Minister's office even understand GHG inventory reports from the Ministry for the Environment?
