<p>"On an average, 1.9 tonne of CO2 is emitted for every tonne of steel produced globally. The average CO2 by SAIL and RINL during 2008-09 was 2.99 tonne and 3.18 tonne respectively against the average of 2.09 tonne of CO2 emitted by Tata Steel," the report, which was tabled in Parliament recently, said.<br /><br />The CAG also pulled up both firms for not fixing any target for reduction in CO2 emission. Tata Steel has set a target of reduction in CO2 emission to less than 2.7 tonnes per tonne by 2012.<br /><br />Energy consumption by SAIL in producing a tonne of steel at 6.72 G.cal/tcs (giga calories per tonne of crude steel) also exceeds the world average of 4.5 -5.5 G.cal/tcs. In comparison, RINL consumes more energy than SAIL at 6.84 G.cal/tcs.<br /><br />"Reasons for consumption of energy in excess of the norms included high fuel rate, coke screening losses in blast furnaces and non-availability of gas holder for storing coke oven and blast furnace gas," the CAG said.<br /><br />SAIL has not set any target for reduction in energy consumption whereas RINL could not meet the targets set by it for reduction in consumption of energy, it said.<br />Meanwhile, SAIL and RINL both use more raw material to produce steel compared to its domestic and global peers.<br /><br />"On an average 2.6 tonnes of raw material is used to produce a tonne of crude steel. The consumption of raw materials by SAIL ranged between 3.26 tonne per tonne of crude steel (t/tcs) and 3.38 t/tcs," CAG report said.<br /><br />"Though there has been reduction in consumption of raw materials over the years, SAIL is lagging behind Tata Steel, which consumed 3t/tcs in 2008-09. In RINL, it ranged between 3.04 t/tcs and 3.1t/tcs," it added.<br /><br />Iron ore, coal, limestone and recycled steel are the main raw materials used for steel making.</p>
