In which Solid Energy defends its lignite proposals before a Parliamentary select committee, defines sustainability loosely, and fails to define some other things at all, except the megabucks

I sat in on Parliament's financial review of Solid Energy yesterday, and heard CEO Dr Don Elder tell the committee that his company — whoops, our company — meets New Zealand’s, and the world’s, sustainability expectations.

That’s sustainability as redefined by Solid Energy.

Southland has, said Elder, world-scale quantity and quality of lignite. On today’s prices, let alone projected future prices, it would earn trillions and squillions of dollars, with which might be bought: hip operations, teachers, rural broadband rollouts galore. A pony from Santa for every child for Christmas. That kind of thing.

I didn’t write the dollar-numbers down. I tried, but the CEO had the bit between his teeth, and he was galloping.

The other reason, actually, why I didn’t write them down is that they're irrelevant. The definition of sustainability, on the other hand, was fascinating.

Solid Energy has pollution estimates for lignite, that they tried to keep secret on ‘commercial sensitivity’ grounds, then released to WWF when forced by the Ombudsman — also because by then anyway the Parliamentary Commissioner for the Environment (PCE) had published her own numbers, that tally with Solid Energy’s own.

I have a copy of the material released to WWF, dated February 8. It only confirms what we knew already — what the PCE, and others, have been saying — that lignite-to-diesel fuel proposals would be much more polluting than the already-polluting conventional diesel. If all diesel in New Zealand was made from lignite, it would double diesel fuel emissions. The PCE illustrated [figure 8.1] how much harder it would make it to deliver on our promises if just one lignite-to-diesel plant proceeded. (Two such plants are proposed, plus some other types of proposals.)

“ The ‘ current CTL ’ column [writes Solid Energy, to WWF] sets out our assessment of emissions that reflect current, well proven technologies (1990/2000s) for a plant based in a first world country. This is our base life cycle assessment we are using for our investigations into a CTL plant in Southland.” It shows an emissions factor of 6.1kg CO2eq per litre, compared to crude-to-diesel's 3.2kg CO2eq per litre. The lowest of the numbers in the other columns is 4.3 — around a 30% increase. This is based on demonstration technology in China, and an assumption that “50% of the CO2 generated as part of the process is sequestered”.

But the PCE said carbon capture and storage is "expensive and risky", a "major challenge", and it would be "irresponsible to make decisions now that rely on CCS becoming both practical and economic". One recent report from Canada has the ground “fizzing like soda pop”. In another OIA response dated February 8, to the Green Party, Solid Energy says that it has no reports or documents at all regarding the quantity of greenhouse gas emissions that it could potentially offset from bio-sequestration. That 50% assumption, then, is speculative, at best.

Dr Elder showed a powerpoint slide headed “ meeting New Zealand ’ s sustainability expectations ”. I t reproduced this “ business sustainability principles ” page. It was his explanation of how Solid Energy is meeting global and local sustainability (my emphasis) :

“ For our business to be sustainable in the long term we must carry out all our activities in ways that achieve our current business objectives without unreasonably compromising our ability to meet our future objectives.

“ We will therefore manage our business in accordance with sustainability principles that consider our specific expectations for value, our people and communities, health and safety, the environment and our reputation. ”

Here is the United Nations’ different definition of ‘sustainable development’:

“Sustainable Development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”

The UN definition is about the needs of future generations, not Solid Energy’s future objectives. It is about sustainability, not business sustainability. Here’s our own Resource Management Act definition.

Elder agreed that a solely business focus would not be defensible. That is why — he said, stepping adroitly sidewise — public support, communities, environment, reputation are all important. Solid Energy’s definition, he believes, is better and broader than the UN's.

It’s certainly different.

In addition, the company aims for a net positive effect on the New Zealand (my emphasis) environment, taking into account “all aspects of the environment”. It has met this every year, since 2003.

Green Party committee member Kennedy Graham thought that, given the SOE’s other promises — sustainability, net positive environmental effect, all aspects of the environment — logically it must be necessary for Dr Elder to be able to assure the committee that lignite would show a net reduction in emissions. The PCE, by contrast, had concluded “large scale lignite use will have negative impacts of national significance”.

We’re all aware that 'net reduction in emissions' is only an accounting treatment, offered Elder, cannily — not the truth of what the environment sees. What we’ve made clear [he said], in looking at lignite development in Southland, is that the energy potential there is clear. Questions about carbon component or footprint, and exactly how one might deal with that, were issues yet to be resolved. It was a very important part of the projects’ evaluation. We don’t have all those answers yet. These are projects in the pipeline, and issues under investigation. The argument on day one that the carbon emissions risk makes the projects unacceptable is an argument we simply don’t accept.

Whereas Solid Energy is happy to rely on the PCE’s recognition of its ‘net positive’ environmental efforts ("praised by Parliamentary Commissioner for the Environment" read the proud legend, on that slide), when it came to her particular view on lignite emissions, he felt she had got it all wrong. He wanted to clarify for the committee her assumptions: she had been referring almost solely to greenhouse gas, not to the economics at all, which she lacked the information to address, nor the other facets of people, community, and so on.

Dr Graham also had a matter he wanted to clarify for the committee, on the PCE's behalf. "The implications, global and NZ national, of rising greenhouse gas emissions will engulf your 'broader' considerations."

And that was the end of it.
