He said, "...the Government does not consider it appropriate for worst-case assumptions to become the default basis for investment decisions that impose significant costs on current and future ratepayers."
The
Minister's letter signals a significant change in the Government's expectations
regarding the way councils use high-end climate scenarios. This is particularly
important where climate modelling has consequences not only for Council
expenditure but also for land-use controls, property rights, development
opportunities and property values.
We understand Whangārei District councillors have not formally
discussed the Ministers letter so we have asked its CEO if it currently uses
RCP8.5, or modelling substantially based on RCP8.5, as its primary or preferred
climate scenario for any planning, infrastructure, asset management or
regulatory purposes, and if so what action it intends to take in response to
the Minister's request that councils review their climate change planning
assumptions and decision-making frameworks.
We
are awaiting his reply.

LETTER TO WDC, CEO
To: The Chief Executive, Whangarei District Council
INFORMATION REQUEST Re: Council response to Minister of
Climate Change – climate change planning assumptions
In particular, he states that high-end scenarios such as
SSP5-8.5 and its predecessor RCP8.5 should be regarded as less likely,
high-impact scenarios suitable for stress testing and contingency planning,
rather than automatically being treated as the central or most likely future
for decisions affecting infrastructure, land use, property rights or rates.
- What action does the Whangarei District Council intend to take in response to the Minister's request that councils review their climate change planning assumptions and decision-making frameworks?
- Does the Council currently use RCP8.5, or modelling substantially based on RCP8.5, as its primary or preferred climate scenario for any planning, infrastructure, asset management or regulatory purposes.
- If so, which Council plans, policies, hazard maps, infrastructure programmes, planning rules or other regulatory instruments currently rely upon RCP8.5?
- Does the Council intend to review its use of RCP8.5 and, where appropriate, replace it as the primary planning assumption with a range of credible scenarios, including medium emissions scenarios?
- Will the Council review existing planning rules, hazard overlays or other regulatory restrictions affecting private property where those restrictions have been substantially based on RCP8.5 modelling?
- Has the Council undertaken, or does it intend to undertake, an assessment of the additional costs to ratepayers arising from infrastructure and other expenditure based on RCP8.5 compared with more moderate emissions scenarios?
- How does the Council intend to demonstrate that future climate-related expenditure is proportionate to the risk, represents value for money, and complies with the Minister's expectation that higher-end scenarios should not automatically become the default basis for major investment decisions?
- Will these matters be reported to elected members for consideration, and if so, when is that expected to occur?
The Minister's letter appears to signal a significant change in the Government's expectations regarding the way councils use high-end climate scenarios. This is particularly important where climate modelling has consequences not only for Council expenditure but also for land-use controls, property rights, development opportunities and property values.
I would therefore appreciate clarification as to whether the Council intends to undertake a formal review of its present approach and, if so, the anticipated timetable for that review.
I would also appreciate copies of, or links to, any reports,
advice or briefing papers prepared for elected members or Council management in
response to the Minister's letter.
