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.

Join the Movement

Steel is at the heart of the global economy – and the climate challenge. The work we do now will shape the industry of the future.

Find out how you can get involved here.

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.

To help improve the accessibility of ResponsibleSteel’s emissions methodology and accelerate robust emissions accounting and reporting, ResponsibleSteel has today published extracts from Principle 10 of the ResponsibleSteel International Production Standard relating to Climate Change and Greenhouse Gas (GHG) Emissions.

Importantly, this is not an independent standard against which steelmakers can make certification claims. Instead, ResponsibleSteel's Fundamentals for GHG Emissions Accounting and Classification is designed as a valuable resource for steelmakers, steel buyers, policymakers, investors, and civil society organisations to use as a reference to measure and track progress as the global industry transitions to lower-emission production practices.

The document aims to improve the comparability, consistency and transparency of emissions accounting and reporting across the global steel industry by outlining three of Principle 10’s fundamental components:

1. ResponsibleSteel’s methodology for the calculation and disclosure of crude steel GHG emissions intensity at the site level.
2. ResponsibleSteel’s classification system to assess a steelmaking site’s decarbonisation progress.
3. ResponsibleSteel requirements for GHG emissions intensity declarations at product-level.

ResponsibleSteel’s “Decarbonisation Scale” approach enables all steelmaking sites, globally, to be compared on a like-for-like basis, based on transparent and fair accounting rules. By adopting this approach, the industry has the opportunity to increase the transparency and consistency of emissions data across the value chain, reducing administrative burdens and enabling more effective implementation of decarbonisation policies and mechanisms.

This new publication will be particularly valuable for stakeholders either looking to align with ResponsibleSteel’s approach or to build interoperability between GHG-specific frameworks, regulations, and procurement systems.

It is important to note that no claims relating to ResponsibleSteel certification, or its equivalency, or Decarbonisation Progress Level achievement, can be made based on this document alone. The document only represents a subset of Principle 10, which in full also addresses corporate commitments to the Paris Agreement, climate-related financial disclosures, and additional site-level emissions reductions. Nor does it include any of the other 12 Principles outlined in the Production Standard relating to the responsible production of steel.

We believe that truly responsible steel production requires steelmakers to go beyond decarbonisation and take steps to mitigate other social and environmental impacts. But amidst the growing urgency of the climate crisis, ResponsibleSteel remains committed to supporting global steel decarbonisation through practical tools developed with multi-stakeholder support. This latest publication reflects that commitment to offering robust, credible, scalable tools to accelerate emissions reductions at scale.

ResponsibleSteel and the Low Emission Steel Standard (LESS aisbl) today jointly release a new policy briefing, ‘The Steel Decarbonisation Scale’, urging European policymakers to adopt a more robust and realistic approach to steel decarbonisation—one that recognises the physical limits of scrap supply and incentivises genuine emissions reductions across all steel production routes.  

The study highlights that Europe’s steel industry, as the world’s second-largest producer, is responsible for 6% of the European Union’s total emissions. With ambitious EU targets aiming for a 55% reduction in net greenhouse gas emissions by 2030 and net zero by 2050, the way steel decarbonisation is measured and incentivised is of critical importance.  

A key finding of the study is that current policy discussions, including the European Steel and Metals Action Plan (ESMAP) and proposals for voluntary carbon labels for steel, risk undermining climate goals if they fail to account for the fundamental constraints on scrap availability. Despite a high global steel recycling rate of 85%, only about 32% of the world’s demand for new steel can currently be met with recycled scrap due to the long lifetime of steel products, according to the International Energy Agency (IEA). While the amount of available scrap is set to increase, the IEA estimates that scrap will still only be sufficient to meet 46% of steel demand by 2050.

“Steel decarbonisation requires an appropriate base for comparing steel products in terms of their global climate impact,” said Dr. Martin Theuringer, Secretary General of LESS aisbl. “Scrap is a valuable and limited resource. Any label or standard that ignores this risks distorting markets and ultimately slowing down the transition to truly low-emission steel. Our approach ensures that both primary and scrap-based production are incentivised to decarbonise, not just to compete for a fixed pool of scrap.”  

ResponsibleSteel and LESS propose the adoption of a “steel decarbonisation scale” that complements traditional carbon footprinting by explicitly accounting for the ratio of scrap and primary iron used in steelmaking. This approach, already recognised by the G7 and incorporated into international standards, would:  

• Prevent fruitless competition for a limited scrap supply  
• Incentivise decarbonisation across all steel production routes  
• Promote technology-neutral, WTO-compliant solutions  
• Support the competitiveness of European industry while advancing global climate goals  

“A European label for steel is a great opportunity to incentivise steelmakers to become globally competitive on their real decarbonisation progress,” said Annie Heaton, CEO of ResponsibleSteel. “A well-designed classification system will do this by taking into account scrap content in addition to the measurement of steel‘s carbon intensity, recognising that scrap will at best provide half of the world’s steel by 2050. As a result, this ‘steel decarbonisation scale’ approach incentivises investments that drive progress in the steelmaking process itself, whether in primary or secondary iron and steel making.”  

The two organisations call on the European Commission to integrate the steel decarbonisation scale into the development of voluntary labels, lead markets, and investment support mechanisms, ensuring that future measures are effective, fair, and aligned with Europe’s climate ambitions.
