Govt backs installation of clean Electric Arc Furnace at NZ Steel Glenbrook site to halve coal useWill remove at least 800,000 tonnes of pollution each year – equivalent of taking all the cars in Christchurch off the
roadAchieves over 5 percent of all NZ’s required emissions reductions between 2026-2030Scrap steel will be recycled, rather than shipped offshore
The Government is partnering with New Zealand Steel to deliver New Zealand’s largest emissions reduction project to
date, with half of the coal being used at Glenbrook steel to be replaced with electricity to recycle scrap steel.
Prime Minister Chris Hipkins made the announcement alongside Energy and Resources Minister Megan Woods and Climate
Change Minister James Shaw at the Glenbrook steel factory in South Auckland today.
“This size of this project demonstrates how serious the Government is about reducing New Zealand’s emissions as fast as
possible,” Chris Hipkins said.
“This project dwarfs anything we have done to date. Alone, it will eliminate one per cent of the country’s total annual
emissions.
“The plan means New Zealand businesses will have access to locally produced, cleaner steel, and high value jobs are
protected that otherwise might have gone offshore.
“Partnering on this project with New Zealand Steel makes sense because it delivers such huge benefits for our
environment. Without Government investment this wouldn’t have happened, so it’s fantastic to see what working together
can deliver,” Chris Hipkins said.
The conditional deal with NZ Steel will be part funded up to $140 million from the $650 million Government Investment in
Decarbonising Industry (GIDI) Fund, which enables partnerships with industry to reduce their emissions. The rest will be
funded directly by NZ Steel.
“The Government is partnering with NZ Steel to reduce 800,000 tonnes of climate pollution from its Glenbrook mill each
year. That’s the equivalent of taking approximately 300,000 cars, or all the cars in Christchurch, off the road,” Megan
Woods said.
“The Government will help co-fund an electric arc furnace to replace the existing steelmaking furnace and two of the
four coal-fueled kilns.
“The installation of an electric arc furnace at Glenbrook means NZ Steel will cut its emissions by more than 45 per cent
and will produce 100 per cent of its annual steel production as lower carbon steel.
“To understand the scale of this project, it reduces more emissions on its own than all the other 66 GIDI projects we
have approved to date.
“Our partnership with NZ Steel shows we can tackle the challenge of decarbonising even our hardest to abate and largest
emitting industries. This investment would not happen without government support.
“Steel is critical to our economy for manufacturing and construction. Lower carbon steel production at Glenbrook has
massive wins for our materials supply chain. It also helps retain a significant local source of employment.
“We are proving once again that decarbonisation does not mean de-industrialisation. It demonstrates how the transition
to a low emissions economy can not only be good for the climate, but also a win for minimising waste, retaining jobs,
and improving New Zealand’s economic resilience,” Megan Woods said.
“Melting scrap steel using electricity, instead of converting ironsands into steel using coal, will substantially reduce
the emissions generated from NZ Steel’s current activities. It will also build a more circular, resilient economy. This
will put New Zealand in a much better position to meet its climate target of net zero carbon by 2050,” James Shaw said.
“This deal is estimated to contribute 5.3 percent of the emissions reductions needed under New Zealand’s second
emissions budget (2026-2030), and 3.4 percent within the third emissions budget (2031-2035).
“The economics of this really stack up, especially compared to current carbon prices. The lifetime abatement cost is
forecast at $16.20 per tonne. Current carbon prices are around $55 per tonne. In the long term this saves the Government
and the country money.
“We must reduce our reliance on fossil fuels to help avoid the worst of climate change. Switching to cleaner ways of
generating process heat is one of the biggest opportunities we have to reduce our domestic emissions and meet our
international climate commitments.
“Adaptation to protect our communities against our changing climate is important. But we cannot underestimate the need
to cut the pollution that causes climate change in the first place. We cannot underestimate the benefits a low emissions
economy will bring for New Zealanders,” James Shaw said.
