ResponsibleSteel is the steel industry's multi-stakeholder sustainability standard, covering both steelmaking sites and, through its input-mining requirements, the mines feeding them. Its International Production Standard (v2.1.1) sets 13 principles spanning climate and GHG emissions (including site-level decarbonisation requirements), water, biodiversity, human rights, labour rights and community relations, with certification by accredited third-party bodies and public audit summaries. A separate Chain of Custody mechanism supports "ResponsibleSteel certified steel" claims into automotive and construction markets — significant because steel buyers increasingly need documented embodied-carbon and sourcing credentials. Membership includes major producers such as ArcelorMittal and BlueScope alongside civil-society organisations. Certification is site-specific and issued at progress levels; it certifies the site against the standard's requirements, not every product line or corporate claim. The standard's climate requirements set site-level emissions intensity thresholds tied to scrap share — a design that forces decarbonisation pathways rather than offsets. Certification has become a procurement reference in automotive and construction supply chains seeking lower-carbon steel. The certification does not automatically apply to every product, service or claim made by the certified organisation.
Conditional relationships
Claims it may support
A relationship does not mean that the standard proves or validates every use of a claim.
Current certificate from an accredited/approved certification body, valid for the claimed product, site or scope
Assurance
Accredited third-party site audits against 13 principles; progress levels toward Certified Steel
Chain of custody
Site-level certification today; downstream Chain of Custody Standard in development (draft v0.2 consulted 2024; piloting) — not yet operational — claim wording must reflect this custody model
