Twenty-one iron and steel plants, having capacity of 0.5 million tonnes a year and above, are up for an independent “green” rating. The Centre for Science and Environment (CSE), a New Delhi-based NGO, has completed a survey of the country's top steel-sector players for the environmental ratings.
The results of the survey, conducted over around one year and nine months, and the rating details will be announced next month. The centre would also release a 200-page book on the environment status of the domestic steel sector on May 17.
