Government investment is being touted as a vital measure to encourage companies to decarbonise.
New Zealand Steel will be given 140-million dollars to help replace half of the coal at its Glenbrook site with electricity.
Chief Executive Robin Davies says there's no direct financial benefit for the company, only an investment in reducing carbon.
He told Mike Hosking that without the Government's help the project wouldn't be able to be done now.
Davies says reduction efforts would have been delayed several years.
