On 23 April 2026 ArcelorMittal released its 2026 Sustainability Report, a comprehensive update on the group’s progress toward safer, lower-carbon and more responsible steel production. The document was prepared in line with the EU Non-Financial Reporting Directive and references global frameworks such as IFRS, GRI, SASB, the UN Global Compact and the UN Sustainable Development Goals. The report frames two priorities as most material for the company: robust safety performance and a disciplined approach to the energy transition, and it sets out how those priorities interact with competitiveness, policy shifts and investment choices.
ArcelorMittal’s chief executive, Aditya Mittal, underscores that steel will remain essential even as production methods change, and reiterates the group’s long-run aim of net-zero by 2050. The company notes that the pathway to that ambition requires adapting near-term expectations because of evolving macroeconomic and policy realities. The report therefore keeps the long-term goal intact while revising the projected 2030 emissions reduction range based on current market conditions and committed investments. Throughout, the company signals a broader strategy that combines operational transformation, new product offerings and expanded renewable energy activities.

Safety transformation: momentum and measures
ArcelorMittal completed the first full year of a planned three-year safety transformation programme, with measurable gains across core indicators. The company reports more than a 50% year-on-year reduction in its fatality frequency rate (FFR) — the lowest level recorded in its history — and a 7% reduction in the lost-time injury frequency rate. To support these outcomes, over 130 safety roadmaps with more than 3,000 targeted actions are being implemented globally as part of a unified “One Safety Culture” approach. The report stresses that maintaining progress requires continuous vigilance, disciplined execution and expanded process safety work in higher-risk installations to move toward the ambition of zero fatalities and zero serious injuries.
Climate action and energy transition: recalibrated near-term expectations
ArcelorMittal reports that absolute Scope 1 and 2 emissions have fallen by 47.7% since 2018 on an absolute basis that includes portfolio changes, with a 2026 group carbon intensity of 1.79 tCO2e per tonne of steel. Based on investments already committed and the current policy and market backdrop, the company now expects up to a 10% improvement in carbon intensity by 2030 versus 2018, while retaining the net-zero by 2050 objective. The report explains that geopolitical and energy-security pressures, inflation and competitiveness concerns have made the near-term transition more complex than initially assumed.
Dunkirk transformation
A flagship example cited is the €1.3 billion project at ArcelorMittal Dunkirk to replace a blast furnace with a 2-million-tonne electric arc furnace (EAF), expected to lower that site’s emissions by roughly 25%. The initiative has secured financial support from the French government and access to competitively priced low-carbon power through a long-term contract with EDF, illustrating how public policy and energy contracts can de-risk major industrial decarbonisation investments. Across the portfolio, the company expects around 5.4 million tonnes of additional EAF capacity to be operational by 2030.
Renewable energy portfolio and power supply
ArcelorMittal now has about 2.8 GW of renewable projects either commissioned or under development on an equity basis. Specifically, 1.9 GW (1.6 GW equity) of solar, wind and hybrid capacity is already commissioned across India, Brazil and Argentina, and a further 1.4 GW (1.2 GW equity) is under development with commissioning planned by 2028. These assets aim to supply low-carbon electricity to steel sites and joint ventures, reducing both emissions and energy costs. The company groups strategic actions into three themes: renewable energy, materials and solutions, and operational transformation, with revenues from selected low-carbon segments representing roughly 13% of company sales in 2026.
People, innovation and environmental performance
Workforce development and technology are central to the sustainability story. In 2026 the group invested in expanded learning, leadership programmes and large-scale upskilling efforts, including AI-readiness training to equip employees for changing industrial practices. The company also maintained targeted social support, such as reintegration programmes for Ukrainian veterans, which received industry recognition. On innovation the company invested about US$335 million in R&D in 2026, launching 38 new products and solutions intended for sustainable construction, renewable infrastructure and lighter, stronger mobility materials — including an integrated roofing and solar system branded Helioroof®.
ArcelorMittal presents sustainability as core to running a resilient business: managing environmental and social impacts responsibly, acting with integrity, and creating long-term value for communities and customers. The report reiterates the group’s scale — operations in 60 countries, primary steelmaking in 14, revenues of $61.4 billion in 2026, production of 55.6 million tonnes of crude steel and 48.8 million tonnes of iron ore — while highlighting the interdependence of safety, decarbonisation and innovation in shaping future competitiveness.
