Greenhouse Gas (GHG) emissions present one of the greatest environmental challenges in the steelmaking industry. Although several gases make up GHG gases, Carbon dioxide (CO2) comprises the majority of global GHGs.
Qatar Steel strives to be an environmental leader in the industry. Although the company’s overall GHG emissions increased in the year 2017, GHG emissions intensity decreased by 2.2% from 2016 to an intensity of 1.31 metric tonne CO2eq/metric tonne of molten steel in 2017.

Reducing Air Emissions
Qatar Steel prioritizes the health and well-being of all its employees and stakeholders through its unceasing endeavors to enhance the State of Qatar’s environmental quality and managing of the various emissions of its operations. By achieving this purpose, Qatar Steel has reduced the SOx emissions by 79.0% and the particulate matters by 88.0% in the year 2017 due to the operational upgrading of the EAF-3 Plant’s dust collection system, which was achieved at the end of the year 2016. In addition, the improvement of the Continuous Emission Monitoring Systems (CEMS) at Qatar Steel plant has led to a better controlling of the emissions’ measurements. This can be reflected in the measured values of SOx, NOx, and the particulate matter for the year 2017.
Relevantly, Qatar Steel uses low NOxCombustion Technology and Energy Saving Measures in its operations which have resulted in a clear reduction in the emitted amount of NOx, a reduction by 7.8% in the 2017.
