In 2023, the New Zealand government announced an agreement with New Zealand Steel to replace half of the coal being used at the Glenbrook Steel Mill for recycling of scrap steel with electricity. The government characterizes this as the largest emissions reduction project in New Zealand to date. 

The project was to be funded in part (NZD 140 million) by the Government Investment in Decarbonising (GIDI) fund. While GIDI fund has been disestablished this contract is progressing. Emissions reductions expected has increased (to 1Mt pa) and commissioning now likely to happen end of 2025 rather than 2026.
