EN8 GREENHOUSE GAS

Considerable reduction in effective CO₂ emission rate is evident when the credit for slag granulation (as per IISI guidelines) (CO₂ emitted for equivalent amount of clinker used in cement making as replaced by granulated slag) is taken into account. The Boxes indicate the trends in specific CO₂ emission from Steel Works and absolute quantities of emissions over the years.

CO₂ emissions calculations are based on GHG protocol guideline. Specific emission data reported in the box opposite are for the scope without considering mobile emissions, HFC emissions, purchased power and purchased oxygen.

EN9 OZONE-DEPLETING SUBSTANCES

The Steel Works used 7.044 tonnes of refrigerant during reporting period as against 7.90 tonnes of refrigerant used during previous year. The trends of CFC consumption have been provided alongside. Data for other units are not available and shall be reported subsequently.

EN30 INDIRECT GHG EMISSIONS

This report does not include green house gas emissions that are not consequence of Tata Steel’s activities but occur from sources owned or controlled by other entities in and around the organization e.g., the refrigerators and air conditioners supplied by the organization to or owned by the employees at their residences, GHG emission on account of purchase of oxygen, etc.

EN31 HAZARDOUS WASTE UNDER BASEL CONVENTION

The company does not import or export any waste deemed "hazardous" under the terms of the Basel Convention Annexure-I, II, III & VIII. All hazardous waste generated are handled as per the requirement of Hazardous Waste Management & Handling Rules 1989/2000. All hazardous waste are appropriately recycled and or disposed off as detailed at EN-11.

EN32 WATER DISCHARGES, RUNOFF AND THE RECEIVING ECOSYSTEMS

The company discharges its treated effluent from the Works and treated domestic sewage from township to the rivers Subarnarekha & Kharkai. Studies carried out by NEERI in the year ’1993 & ‘2000 to assess impact on eco-systems/habitats of rivers and have found no significant impact on the aquatic eco-system as given in EN20. Noamundi & Joda Mines, West Bokaro & Jharia Collieries have achieved zero discharge. The domestic effluent is discharged through the septic tank – soaking pit route at Mines & Collieries. Sewage Treatment Plants have been provided for the entire township at Jamshedpur.
