Earlier this month my friend James Brown (analyst, economist and co-author of Zero Carbon Options), drew my attention to a new report: the Deep Decarbonisation Pathways Project Interim Report, Australia Chapter. The project is international, and is being run with some connection to the United Nations. This all sounds rather impressive, important and right in my area of interest. However James was concerned that some of the assumptions were peculiar. He had emailed the international project head to raise his concerns.
I took a look at the report. The closer I looked, the less comfortable I felt. While the ostensible goal is one I wholeheartedly embrace, I was concerned this report would potentially send the national conversation backward, rather than forward. I brought it to the attention of a few other parties including my friend Professor Tom Wigley. He, James and I committed to drafting a critique of the report and we got to work.
Late in the piece, a strange thing happened. While approaching some other parties for their review of the critique and potential endorsement, the draft critique was leaked to the authors of the Australia Chapter. Email communication was incoming immediately. To cut a long story short, we declined an offer of personal engagement to instead finish the draft and submit the critique as planned, which was a matter of days away. Our suggestion to the authors was that the critique should be published, along with their response, in the interests of transparency and following the example set by the IPCC.
The authors would not commit to this. They instead reserved the right to respond as they saw fit.
For that reason we have decided to publish the Interim Report and our critique here at Decarbonise SA.
We note here, as in the critique, that this is only an interim version of the report that we are commenting on and more information and a final version will be forthcoming in the near future. We note also that in the main report (as opposed to the Australia Chapter) we find much to agree with in terms of the value in developing deep decarbonisation pathways as part of a decisive response to climate change. As will be apparent in the reading, we have many and serious concerns about the Australia Chapter and we think a published written critique is the correct step. We were not, and are not, seeking explanations relating to the report. Rather, we believe reports like this should not require explaining. This distinction matters a great deal.
We don’t take the decision to critique this version lightly. A great deal of effort went into it. Nor do we take lightly the decision to publish our critique.
James, Tom and I share a conviction: achieving meaningful action on decarbonisation in a politically and economically complex world demands, as a starting point, work that is balanced, fully cognizant of the many complexities and uncertainties, and of the highest quality to underpin arguments and decision-making processes. Anything less and we are destined to repeat the past: environmentalists talking to themselves while the world heats up for another generation.
This is the Australia Chapter of Deep Decarbonization Pathways Project.
This is our critique.
The final version of the report has now been released. We have noted two changes.
1. Correction of the error relating to electricity making up two thirds of Australia’s emissions. This sentence has been eliminated
2. The contingency scenario with nuclear now has less nuclear. It has been lowered to 14 %.
There appears to be no other change of material significance whatsoever.
