ResponsibleSteel Certificate

A steelmaking site has been independently audited against the ResponsibleSteel International Standard's environmental, social, and governance requirements (Certified Site); Certified Steel additionally requires the site to meet requirements on responsible input sourcing and greenhouse-gas performance, with graded progress levels, allowing product-level claims for steel from that site.

• Product-level claims from a Certified Site certificate alone — only Certified Steel supports claims about the steel itself.
• That certified steel is 'green' or near-zero-emissions — Certified Steel progress levels reflect decarbonisation progress, not zero-carbon steel.
• Recycled content percentages, which require separate evidence.

• Has Responsible Material Sourcing Certification →

Expiry matters — check the certificate is current.

Distinguish Certified Site (how the site operates) from Certified Steel (claims about the steel product, including GHG progress levels) — marketing often blurs the two.

For Certified Steel, note the progress level: levels are graded and lower levels reflect early decarbonisation progress.
