We’re shaping  a more responsible steel industry.

Steel is everywhere. It’s in the buildings we live and work in, the cars we drive, and the wind turbines we’re relying on for a low-carbon future. It’s strong, versatile and essential. But it also comes with a heavy social and environmental footprint, having a profound impact on people and the planet.

As global attention increasingly began to zero in on climate and sustainability issues, industries like agriculture, textiles, and timber began developing standards to measure and improve their impacts. But steel, despite being one of the most widely used and most carbon-intensive materials globally, remained largely outside this conversation. There was no common language, no shared benchmark, and no way of independently measuring industry progress.

An idea takes shape

The concept for a global standard for steel started to take shape between 2011 and 2015, developed initially by the Australian Steel Stewardship Forum. The foundations were laid for an international, non-profit, multi-stakeholder organisation to tackle the most pressing sustainability issues in the steel industry.

By 2015, industry stakeholders, including BlueScope and ArcelorMittal, began coming forward to support the initiative, recognising the need for an independent initiative to drive and measure industry progress. In 2016, the first face-to-face council meetings were held, and the organisation was incorporated as the Steel Stewardship Council.

The development of the first Standard

Developing a sustainability standard for one of the world’s most complex industries was no small task. But by 2017, the first working draft of ResponsibleSteel’s Production Standard had been developed using ISEAL’s Codes of Good Practice as a reference.

Over the next two years, input from over 70 organisations and 180 individuals helped shape and strengthen the standard. In 2019, the ResponsibleSteel International Production Standard Version 1.0 was approved by both business and civil society members, marking a critical milestone in making responsible steel a global reality.

The first ResponsibleSteel Certified Sites

Within two months of launching the Standard, the first steel sites began the audit process. Despite setbacks caused by the COVID-19 pandemic, the world’s first ResponsibleSteel certifications were awarded in 2021 to four ArcelorMittal sites in Belgium, Germany, and Luxembourg.

Momentum quickly grew. By 2022, sites in Australia, North and South America, and Asia were certified, and by November, ResponsibleSteel Certified Sites spanned five continents and covered over 100 million tonnes of steel production.

Raising the bar: Certified Steel

Even before the first certificates were issued, work had already begun on a more ambitious task to define what truly low-emission, responsibly sourced steel should look like.

This led to the development of rigorous requirements on decarbonisation and materials sourcing. These requirements were refined through member working groups, public consultations, and a 12-month test phase, before being finalised as part of the ResponsibleSteel International Production Standard Version 2.1, published in 2024.

Version 2.1 marked the green light for steelmakers ready to take their ResponsibleSteel journey to the next level: Certified Steel. In September 2024, at Climate Week NYC, U. S. Steel’s Big River Steel was unveiled as the first site globally to market and sell Certified Steel.

What’s next?

What began as a small initiative has become a global multi-stakeholder movement. Today, the ResponsibleSteel community numbers over 160 members from across the steel value chain and civil society organisations.

With the support of our members and partners, we continue to work to improve our standards and certification programmes. This includes work on the revision of the Production Standard to ensure it remains aligned with the needs of the industry and our planet, and the development of a Chain of Custody Standard to enable downstream buyers to make credible claims relating to the amount of Certified Steel in their products.

Together, we’re striving to construct an ecosystem to support a positive industry transition by engaging the full value chain, as well as policymakers and finance institutions, and by championing consistent, comparable emissions measurement to support alignment across standards and build a market for low-emission and near-zero steel.

thyssenkrupp Steel has achieved Core Site Certification for its Duisburg site, the company's first certification against the ResponsibleSteel International Production Standard.

Situated in Germany’s industrial heartland in the Ruhr region, the Duisburg site is at the centre of thyssenkrupp Steel’s operations. In continuous operation since 1891, its location on the Rhine enables fully integrated steel production. The site has an annual pig iron capacity of approximately 11.7 million tonnes from four blast furnaces and a crude steel capacity of around 11 million tonnes.   Looking ahead, thyssenkrupp Steel aims to reduce its Scope 1 and 2 emissions by 30% by 2030 compared to 2018 levels and cut Scope 3 emissions across the value chain by at least 16%.

Annie Heaton, CEO of ResponsibleSteel, commented, “The certification of thyssenkrupp Steel’s Duisburg site marks a major milestone as the largest steelmaking site in Europe to achieve ResponsibleSteel certification to date. It reflects thyssenkrupp’s commitment to rigorous, international sustainability standards and an assurance system that involves multiple stakeholders and goes beyond carbon emissions to include other environmental and social requirements. With plans underway to introduce direct reduction technology, this certification represents an important step on the site’s path towards responsible, lower-emission steel production. And at a time of growing pressure and uncertainty for the industry, thyssenkrupp’s achievement is evidence of the practical steps being taken to drive real, measurable progress.”

thyssenkrupp Steel serves a broad customer base across 48 countries, with key markets including the automotive industry, mechanical engineering, industrial machinery, special vehicle manufacturing, household appliances, packaging, energy, and construction.

Marie Jaroni, Chief Transformation Officer at thyssenKrupp Steel, states: "Achieving ResponsibleSteel certification is a significant milestone for our company. It assures our customers that we uphold the highest standards of environmental and social responsibility. This bolsters confidence in our products and processes and underscores our dedication to a sustainable future."

Duisburg employs over 16,000 workers and contractors, representatives of which were consulted as part of the site’s audit alongside several external stakeholders. Representatives from the union, embassy, local authorities, water management body, worker support network, academic, community members, and neighbours were invited to give their input to the audit.

Steel is everywhere. It’s in the buildings we live and work in, the cars we drive, the bridges we cross, and the products we use every day. It's an essential material in the modern world and critical to the renewable energy transition.

But steel also comes with a cost. It’s a major source of emissions, contributing to 10% of global energy-related emissions, and the way it’s produced can have serious impacts on local communities and ecosystems. With growing pressure to reduce emissions, improve supply chain practices, and meet evolving regulations, the steel industry faces a huge challenge.

That’s where ResponsibleSteel comes in.

We're a global not-for-profit organisation created to maximise steel’s contribution to a sustainable world. Our mission is to be a driving force in the production of socially and environmentally responsible near-zero steel, steel that buyers and investors can get behind.

ResponsibleSteel supports:

• Steelmakers to demonstrate good practice on social and environmental issues, and measurable progress on decarbonisation
• Steel buyers and investors to make informed decisions and reduce risk in their supply chains and portfolios

Together, we have the opportunity to do things differently and support the industry's transition to a responsible, low-emission future.

What we do

ResponsibleSteel is the global standards and certification initiative for the steel industry. Working collaboratively with over 160 members from across the steel supply chain and civil society, we have developed the ResponsibleSteel International Production Standard via a process that uses the ISEAL Codes of Good Practice as a reference.

The ResponsibleSteel International Production Standard contains 13 Principles covering key environmental, social and governance issues identified and agreed upon by our members for the responsible production of steel. The Production Standard evaluates the full picture—not just carbon emissions, but also labour rights, human rights, water use, biodiversity, raw material sourcing, and other key issues that affect people and the planet.

Certification against the Production Standard combines all the complexities of good social and environmental performance in one indication. Steelmaking sites must undergo rigorous, third-party audits to become certified, ensuring that a site is meeting the highest environmental and social standards.

Certification provides steelmakers with a clear framework for improvement and helps buyers, investors, and other stakeholders understand whether a site is operating responsibly.

How it works

Certification is broken down into Core Site Certification and Steel Certification, or ‘Certified Steel’.

Core Site Certification against the Production Standard is the first step sites can take on their ResponsibleSteel journey. Sites undergoing Core Site Certification are evaluated against over 300 core requirements, covering the key social and environmental aspects of steelmaking such as pollution, biodiversity, water stewardship, labour rights and local communities. Core Site Certification is a major achievement, requiring commitment at the corporate level and across all of the site’s operations.

Now, steelmaking sites can build on their Core Site Certification, pursuing certification against the Production Standard’s Progress Level requirements for decarbonisation and responsible materials sourcing. The Production Standard defines four Progress Levels for the measurement of decarbonisation and responsible materials sourcing. Steelmaking sites that achieve at least Progress Level 1 for both are able to market and label their products as ‘Certified Steel’.

Why it matters

The need for reliable, consistent, comparable data in the steel industry has never been greater. Governments are introducing stricter climate disclosure regulations. Steelmakers and buyers are under pressure to reduce emissions and meet consumer demand for more sustainable products. And investors want to know which steelmakers are producing responsibly and planning for the future.

Certified Steel helps steelmakers show progress, build trust, and stand out in a competitive market. And it gives buyers and investors the confidence that a site has not only met the strong environmental and social criteria required for Core Site Certification, but is also making measurable progress on decarbonisation and materials sourcing. Certified Steel:

• Assures that steelmakers are meeting the highest social and environmental standards
• Offers credible, comparable emissions data to simplify decision-making
• Reduces supply chain and financial risks, protecting reputation and value

Working together to shape steel’s future

The industry will not transform overnight. And the transition cannot be left to steelmakers alone. Driving progress in the industry will require clear demand signals from steel buyers and backing from investors. That’s why we are working closely with buyers and investors to forge a path to a sustainable future for steel. Together, we’re helping to build a global market that is better for people, for business, and for the planet.
