Tata Steel green steel transition: EAF, HIsarna, and net zero by 2045

Tata Steel has reaffirmed its net-zero carbon emissions target for 2045, announcing progress on several green steel projects. The company commissioned its first Electric Arc Furnace in Ludhiana, India, which runs on recycled scrap and gets nearly half its power from renewables, producing steel with an emission intensity below 0.3 tonnes of CO2 per tonne. In the UK, the Port Talbot EAF project backed by a 1.25 billion pound investment is expected to cut emissions by 50 million tonnes over ten years. Tata Steel is also advancing HIsarna technology in Jamshedpur, which skips several energy-intensive steps in conventional steelmaking, and exploring hydrogen-based production and carbon capture. The company has signed a 379 MW renewable power agreement with Tata Power and now sources 6.4 percent of its energy from clean sources. These moves show how a major industrial emitter is shifting from blast furnaces to lower-carbon methods, though the 2045 net-zero date still leaves room for debate on interim milestones and the scale of offsets needed.
