The Centre for Science and Environment (CSE) has completed a survey of India’s top steel-sector companies for the environmental ratings.

As per the CSE survey, twenty-one iron and steel plants, having capacity of 0.5 million tpa and above, are likely to get an independent “green” rating. The survey included relatively smaller plants as well as the large integrated manufacturing units, but left the captive mines out of its ambit. The survey included all those units which met capacity criterion in the financial year of 2009-10.

The ratings are based on life-cycle analysis using more than 150 parameters. State promoted steel plants included five plants of SAIL in Chhattisgarh, Orissa, Jharkhand, and West Bengal, Vizag Steel of RINL and Neelachal Ispat at Kalinganagar in Orissa. The CSE survey covered private facilities such as Jamshedpur plant of Tata Steel, Vijaynagar unit of JSW Steel, Hazira plant of Essar, Raigarh unit of Jindal Steel & Power, JSW Ispat's Dovli plant, Monnet Ispat's Raigarh unit, Visa Steel's Kalinganagar plant and Jai Balaji's Durgapur unit.
