CO2 emissions resulting from the production of steel remain as one of the central challenges facing the steel industry . The International Energy Agency (IEA) estimates that about 7% of the total world CO2 emission is associated with the global steel industry.
Qatar Steel takes this challenge seriously and is exerting all possible efforts to improve GHG and air emissions. The company’s performance in reducing the emission intensity is better than the industry average according to a recent benchmark study. Qatar Steel has been successful in reducing direct CO2 emission intensity over the years to reach about 1 ton of CO2eq for each ton of steel sold, which compares favourably to the industry average of about 2 ton of CO2eq.

Qatar Steel has reduced energy consumption and the production of SOx (sulfur oxide) during the manufacturing process, with efforts such as: reductions to fuel consumption, use of low-sulfur fuels, switching to municipal gas, as well as exhaust-related measures such as desulfurization. Likewise, to reduce NOx (nitrogen oxide) emissions, Qatar Steel has implemented efforts such as the use of low NOx combustion technology and energy saving measures. Despite recent increases in air emissions, Qatar Steel’s average emission intensity is still below the industry average for both NOx emission intensities which is 1.3 and SOx emission intensity which is 0.94.
