Improving air quality

Air quality is one of the most salient issues for the people who live and work around our sites, and we have been working for many years to understand and address community concerns. Through better processes, investment in R&D, and investment in capital improvements, we have made significant progress. In Ostrava (Czech Republic), for example, our steel plant has cut its ducted dust emissions by 25% year on year after installing 13 new dedusting facilities in 2015. This takes the plant far beyond European emission limits, which the plant was compliant with well before they became binding in 2016.

Looking at the global picture, our air emissions are affected not only by the investments we make and technology we use but the mode of production. Over the past year in developed economies, we have continued to see a shift away from construction products and towards automotive and consumer goods, and this has meant a corresponding move from electric arc furnaces. This has caused a corresponding increase in average air emissions per tonne, which has outweighed the reductions resulting from previous environmental investments. Dust, NOx and SOx emissions per tonne all showed a slight increase this year.

Nonetheless, we know that air emissions remained a concern in a number of places in 2016, including Poland, Brazil, Ukraine, Bosnia & Herzegovina and Canada. We are continuing to invest: of the capital investment we allocated to environmental projects* last year, over 82% was aimed at improving air emissions. At the same time, through our communications and environmental reporting, we work hard to ensure that stakeholder perceptions are based on hard data and real events.

* Environmental projects include those aimed at improved air, land or water management. Energy and carbon projects are reported in outcome 6.

Protecting biodiversity and managing land

We aim to practise good land management wherever we operate, whether in our steel mills or in our mining operations. By working with communities and other stakeholders, we've had considerable successes over the years – in Tubarão, Brazil, for instance, we've planted 2.6 million trees over the past 28 years to reduce wind erosion, and in Liberia, where we operate in proximity to a unique ecosystem, we’ve developed a multi-stakeholder biodiversity programme to ensure the value of this is conserved.

Sharing water with communities

We know how valuable freshwater is to the communities around us – householders, public services and other businesses; at some sites it is also vital to our operations, both in steelmaking and mining. Consuming freshwater responsibly, and making sure that we monitor and maintain the quality of the water we discharge, are both important elements in protecting the environment and ensuring good relationships with our neighbours.



of our water intake from groundwater sources

Our steel plants are designed to treat and recycle the same intake of water repeatedly, often hundreds of times. Given the volumes we need to withdraw, steel plants are typically built in places where surface water is widely available, so water withdrawn from groundwater sources makes up less than 1% of our water intake; and seawater is often used for cooling purposes. Nonetheless, in an era of increasing water scarcity, stakeholders need to be able to access and understand the data, and so how our water use may or may not impact them. We are reviewing the quality of our water data with this in mind.

Circumstances vary from site to site and our net water use – the difference between the water we withdraw and that we discharge – is reported more specifically in our country sustainability reports. Our consolidated figure for net water use across the group is five cubic metres per tonne of steel.

Nonetheless, where freshwater is scarce or when drought strikes, we work with local municipal and water authorities to explore the best sources for our water, including seawater, rainwater, and wastewater from water treatment plants. In 2016, for example, at our Ostrava mill in the Czech Republic, we contributed to the area's watershed planning process after working with the local watershed administrator to manage our water consumption during a drought in 2015. Our Piombino site in Italy installed a desalination plant in 2015, and our Tubarão steelplant in Brazil is investigating this for the long-term future of their operations.

At the end of 2016 we started to review our mapping of water scarcity across our sites, and how we report and measure water. We want to ensure we are reporting high quality data, and focusing on where the risks are, not just from a regulatory point of view, but in terms of all the stakeholders with whom we share freshwater supplies.
