British Steel has revealed £1.25 billion decarbonisation proposals that unions say could see 2,000 jobs lost in Scunthorpe.
The company is planning to shut down blast furnaces at the manufacturing site, replacing them with greener and cheaper electric arc furnaces.
The new furnaces could be operational by late 2025 and would replace the aging iron and steelmaking operations in Scunthorpe which the business says are responsible for the vast majority of its CO2 emissions.
British Steel has started preliminary talks with trade unions about electrification, and has promised to support employees affected by the decarbonisation plans. It has agreed for its proposals to be reviewed by an external specialist on behalf of the trade unions.
The company added that it is working with North Lincolnshire Council on a masterplan to attract new businesses and jobs to the Scunthorpe site, parts of which could become vacant if the proposals go ahead.
