Ministry of Steel on the 23rd December, 2024 has published taxonomy for Green Steel for India for general information. “Green Steel” shall be defined in terms of percentage greenness of the steel which is produced from the steel plant with CO2 equivalent emission intensity less than 2.2 tonnes of CO2e per tonne of finished steel (tfs). The greenness of the steel shall be expressed as a percentage, based on how much the steel plant’s emission intensity is lower compared to the 2.2 t-CO2e/tfs threshold.
Based on the greenness, the steel shall be rated as follows:
- Five-star green-rated steel: Steel with emission intensity lower than 1.6 t-CO2e/tfs shall be defined as fivestar green-rated steel.
- Four-star green-rated steel: Steel with emission intensity between 1.6 and 2.0 t-CO2e/tfs shall be defined as four-star green-rated steel.
- Three-star green-rated steel: Steel with emission intensity between 2.0 and 2.2 t-CO2e/tfs shall be defined as three-star green-rated steel.
- Steel with emission intensity higher than 2.2 t-CO2e/tfs shall not be eligible for green rating.
The threshold limit for defining star rating of Green Steel shall be reviewed every three years.
