5. Trusted user of air, land and water


Our approach to date

Our environmental policy commits us to effective environmental stewardship and preventing pollution. Of our industrial operations, 98% were certified to ISO14001, meaning they are monitoring, actively managing and continuously improving their environment impacts. 


Dust is one of the main environmental impacts of steelmaking, and creates visible pollution both inside and outside the plant. Over the past 25 years, the use of new technology has significantly reduced the amount of dust generated by a typical steel plant. This requires significant capital expenditure, and each year we commit large sums of investment to do this. We also continue to invest in monitoring our emissions, improving our production processes, and using techniques such as ‘green belts’ of trees to filter dust in the air. Other pollutants, such as nitrogen oxides (NOx) and sulphur oxides (SOx), have also been significantly controlled in recent decades.


In our mining operations, we are careful to identify the potential impacts of our operations on air quality, and make plans to mitigate them, and we control our emissions as required by legislation. For example, we try to limit the dust from iron ore stocks by spraying water over them.
