EPD for XCarb® recycled and renewably produced organic coated steel coils Granite® and Estetic®

At BAU, the world's leading trade fair for the construction sector, from 17 to 22 April in Munich, ArcelorMittal's business units will present a wide range of products on offer: from facade solutions and load-bearing structures to roof structures for photovoltaic systems.

Robust, sustainable, and as eye-catching as possible

Steel as a material is playing an increasingly important role in resource-efficient construction. Steel is versatile, fully recyclable, and – thanks to innovative technologies – can be manufactured with a smaller carbon footprint. The use of steel products with reduced CO₂ emissions represents further progress towards a climate-neutral construction industry.

"This year, our focus is on the topic of sustainable construction with steel, highlighting the role that low carbon emissions steel can play in reducing the carbon footprint of the construction sector. Manufacturing methods are changing, which means the use of renewable energies and scrap are increasing. As a durable, infinitely recyclable, but also very versatile material, steel is suitable for any use in the construction industry. And it is an important material in the energy transition, with low-carbon emissions steel needed for wind power or photovoltaics. Visitors to BAU will be able to see this for themselves," says Tapas Rajderkar, Chief Marketing Officer of ArcelorMittal Europe – Long Products.

Carbon emissions reduction thanks to XCarb® steels

Sustainability, circular economy, and ArcelorMittal's XCarb® range are in focus this year. This brings together all the group's manufacturing processes, products, initiatives, and innovation projects aimed at reducing CO2 emissions. XCarb® recycled and renewably produced steel is made in an Electric Arc Furnace (EAF) using 100% renewable electricity and up to 100% scrap, significantly reducing the carbon footprint of steel buildings. Emissions can be as low as 300 kilograms CO₂ per tonne compared with over two tonnes for steel produced conventionally. In the construction of an industrial hall, for example, steel that is recycled and produced with renewable electricity can save as many tonnes of CO₂ as the total steel tonnage required for the building envelope and supporting structure, without changing the construction method or the established building process.

Sustainability goes hand in hand with quality at the world's leading steel and mining group. In addition to the aesthetic aspect, the performance and recyclability of the materials and the construction elements used have an impact on the life cycle assessment of a building. The use of high strength steels contributes to a reduction in the carbon footprint. For example, for the same load-bearing capacity, the carbon footprint of a beam can be reduced by 15 to 20%. When using a composite deck instead of a conventional precast concrete one, the reduction is up to 30%.

A wide range of applications in construction

With the Granite® product family, ArcelorMittal offers a range of organic coated steels for building envelopes with more than 120 colours and textures, guaranteed for up to 40 years. For facade substructures, solar mounting structures, but also cable trays, composite floors, and many more applications, Magnelis® metallic coated steel resists corrosion three times better than regular galvanised steel. Both products are available as XCarb® recycled and renewably produced.

Special roof panels for photovoltaic systems

A few years ago, a solar/photovoltaic system was still a "nice to have", but today it is a standard feature and has even become mandatory for new commercial buildings. ArcelorMittal specialises in the installation of photovoltaic modules on roofs and will be showing its portfolio at BAU. Whether renovating existing buildings or constructing new ones, Ondatherm Solar® roof panels offer simple and quick installation for photovoltaic systems, are robust, and provides a high level of thermal protection. Various flexible solutions are available to customers and builders for mounting the modules.

Sustainable supporting structures

ArcelorMittal will also present its solutions for load-bearing structures at BAU. Cofraplus® 80 composite floor profiles are approved by building authorities as prefabricated steel floors and have a significantly lower carbon footprint compared to prefabricated concrete slabs. For structural applications, high strength HISTAR® steels provide cost and material savings. The weather-resistant Arcorox® steel grades with natural corrosion protection have a long service life and are already being used successfully in bridge construction projects.

BAU 2023

ArcelorMittal Warszawa (ArcelorMittal Warsaw) is among one of the few companies to have received ResponsibleSteel™ certification. After a successful audit by the DNV Poland certification body (an auditor accredited by the ResponsibleSteel™ organisation), ArcelorMittal Warsaw received its certification on 24 January 2023 confirming that it meets all of the criteria included in the ResponsibleSteel™ standard.

ResponsibleSteel™ certification

The audits are designed to verify that a steel plant's operations meet a set of rigorously defined requirements, which the auditors confirm not only on the basis of the documents they receive, but also through a series of interviews with internal and external stakeholders. They take into account a wide range of social and environmental criteria divided into 12 principles. Social criteria include business integrity, relations with employees and communities, human rights, and labour rights. Environmental criteria include climate change and greenhouse gas emissions, water management, waste and noise emissions, and biodiversity.

The auditing process

The audit was conducted by independent auditors from DNV. The first stage, which took place in May 2022, confirmed the steelworks' readiness for the second stage - the essential certification process based on interviews and documentation. The second stage of the audit took place in September 2022. In addition to an in-depth analysis of documents, it included a series of assessments by the auditors verifying how sustainable steel production works in practice at the plant. The auditors focussed on interviews with the management of individual departments, made visits to production areas, and conducted individual and group interviews with employees, trade unions, and other ArcelorMittal Warsaw stakeholders, including representatives of the local community.

On the road to the highest standards

ArcelorMittal wants its stakeholders to be assured that the steel, which is by nature a material with infinite recycling potential, is produced to the highest standards in areas such as health and safety, organisational and management culture, and relationships with the environment - including broad environmental and biodiversity protection. ResponsibleSteel™ is an affirmation of meeting these requirements.

In July 2021, ArcelorMittal announced that its plants in Belgium (Geel, Genk, Ghent, and Liège), Luxembourg (Belval, Differdange, and Rodange), and Germany (Bremen and Eisenhüttenstadt) were the first steel mills in the world to be independently audited and found to meet the standards required under ResponsibleSteel™.

In May 2022, the company's plants in Asturias, Spain and ArcelorMittal Méditerranée in France were also certified. In June, France Nord was also certified, covering its plants in Dunkerque, Mardyck, Desvres, Montataire, Florange, Mouzon, and Basse-Indre.

In November of the same year, ArcelorMittal Poland joined the ranks of certified plants as the first such group of plants in Eastern Europe.

This short video explains how ArcelorMittal will achieve its climate action ambitions. For ArcelorMittal Europe, the ambition is to reduce Scope 1 and 2 CO2 emissions by 35% by 2030. To achieve this goal, it will take a combination of techniques. As you will see in this video, ArcelorMittal’s decarbonisation strategy is based on 3 main levers:

1. Circular steel
2. Innovative DRI
3. Smart Carbon steelmaking

XCarb® towards carbon neutral steel

XCarb® is a trademark registered by ArcelorMittal that represents the clear path taken by the company towards the decarbonisation of the steel production process and the ambitious goal of zero emissions by 2050.

XCarb® will ultimately bring together all of ArcelorMittal’s reduced, low, and zero-carbon products and steelmaking activities, as well as wider initiatives and green innovation projects, into a single effort focussed on achieving demonstrable progress towards carbon neutral steel.

ArcelorMittal has developed two decarbonised production routes (the Smart Carbon route and the innovative DRI route) and is deploying these low-emission technologies across Europe.

Alongside the XCarb® brand, ArcelorMittal has launched three XCarb® initiatives:

• XCarb® green steel certificates: These allow customers to reduce their or their customers' scope 3 emissions. They can be purchased directly from ArcelorMittal Europe – Flat Products in conjunction with a corresponding steel order.
• XCarb® recycled and renewably produced: This is applied to steels produced in an electric arc furnace (EAF) using scrap and 100% renewable electricity.
• XCarb® innovation fund: ArcelorMittal also continues to invest in companies developing breakthrough technologies that will accelerate the steel industry’s transition to carbon neutral steelmaking.
