Controversial 'climate' projects still waiting for money, a year on

Rivers bursting their banks, flash floods and more intense cyclones. How climate change is making floods more extreme.

A quarry and a carbon-emitting pump system were greeted with disdain by climate activists when they were announced as recipients of Government “climate resilience” funding last August.

A year later, they are still awaiting confirmation of whether they will actually get the money.

Muggeridge’s pump station in Waikato, which releases carbon dioxide by draining carbon-rich peatland, and Kumeroa quarry, in Tararua, raised questions last August when they were included on a $100 million list of 29 projects meant to bolster climate resilience.

Projects on the list were “to protect against and mitigate the effects of climate change”, according to then-deputy prime minister Winston Peters and then-infrastructure minister Shane Jones, who jointly announced the funding almost exactly a year ago. They were part of the $3 billion of infrastructure spending announced as part of the Government’s Covid-19 response and recovery fund.

Climate scientists questioned whether those projects fitted the climate resilience description – and queried the wisdom of other listed projects that would encourage more housing development behind stopbanks.

Since then, dozens of other projects announced as part of the Covid recovery have had their funding confirmed by government officials and ministers. Many are already under way and a few are finished.

When Stuff asked the Ministry for Business, Innovation and Employment (MBIE) for an updated list of funded projects from the climate resilience announcement, it supplied a list of 56 projects. Those two projects were missing.

Asked whether they were still going to be funded, MBIE said it could not discuss that, because the approval process was still ongoing. The ministry said a decision was expected “within a few months”.

The final decision will rest with ministers responsible for the infrastructure reference group, most prominently Finance Minister Grant Robertson who is also infrastructure minister.

MBIE said the 56 projects that were currently part of the package were “at various stages of completion” and most were expected to be completed within the next one to three years.

One year and counting

Following criticism that its huge Covid recovery spending package risked locking in high emissions and vulnerability to climate change, the Government announced it was putting $100m into projects around the regions that would boost climate resilience.

Councils were invited to put forward projects that met the description.

But plans to use the funding to keep carbon-releasing peatlands from reverting to wetlands (which would largely halt emissions) and to build a rock quarry were ridiculed by climate activists.

Horizons Regional Council had put forward building the Kumeroa quarry for funding because, it said, it could help supply rock for flood defences.

But when Stuff asked Horizons last year about the project’s expected emissions and links to preparing for climate change, a spokesperson said the roughly $2m contribution from climate resilience funding had been withdrawn after officials looked more closely at the project.

At the time, MBIE denied this and said the quarry was still being considered. Neither party would offer any further comment on the apparent contradiction.

As for the pump station, last month, Waikato Regional Council told Stuff funding of $5.7 million towards the project was approved in principle by MBIE in 2020. (Local councils will also chip in money towards all the projects, under a co-funding model). “The project is sitting with the Infrastructure Reference Group ministers pending a final decision and we continue to await the outcome,” said a council spokesperson.

Soil scientists are concerned about moves to improve and lengthen the life of the pump station, which will create carbon emissions by allowing ongoing draining of 1100 hectares of carbon-rich peat soil for farming.

In total, Waikato’s drained peat soil, which is mainly used for dairying, could be producing as much carbon dioxide annually as Huntly power station, by some estimates, though more and better measurements are needed.

Studies on other drained peat in the Waikato have found it can lose about 3 tonnes of carbon per hectare per year, depending on location, meaning draining an 1100-hectare area might have a similar climate impact to driving from Picton to Bluff 60 times, every year.

Critics fear the approximately $9m investment will end up being futile anyway, because sea level rise will overwhelm the new pump and channel. The current pumps can’t keep up with the combination of sinking soil and land that is already partly below sea level, causing problems for about 20 landowners. If the investment in stronger pumping and deeper drains was abandoned, or directed to offering to buy the land, the land would reflood on its own.

The council has peat management rules in place to minimise the damage caused by drainage, however the protocols themselves say there is no guarantee the measures will reduce carbon losses. The council said last year it had not estimated the greenhouse gas impact, because measurements are specialised and expensive.

Correction: Originally, this story said that the investment in Muggeridge’s pump station was approximately $18m. That figure included others works, such as fish-friendly pumps. The latest estimate to upgrade Muggeridge’s only is $9m (story edited 11.36am, August 4).
