A common language of assessment
Certification against the ResponsibleSteel International Production Standard covers the full range of sustainability issues from biodiversity and decarbonisation to labour rights and local communities. It provides a common language of assessment that steel's customers, communities, investors, and workforce can all get behind.
ResponsibleSteel’s certification scheme is designed to drive progress across the industry, beginning with Core Site Certification. And now, steel sites are encouraged to take the next step, Steel Certification, beginning at Progress Level 1 and working towards Progress Level 4: near-zero steel with the highest standards for traceability.
How does it work?
To be certified, steelmaking sites undergo rigorous audits conducted by independent certification bodies recognised by ResponsibleSteel. The audit report is reviewed by ResponsibleSteel and an independent Assurance Panel before a certification decision is taken. Certificates are valid for three years, but certified sites must undergo a surveillance audit around 18 months in, demonstrating progress on any non-conformities identified during the initial audit.
Sites that achieve Core Site Certification are permitted to use ResponsibleSteel’s ‘Certified Site’ mark to promote the achievement while sites that have undergone certification against the Progress Levels can use ResponsibleSteel’s 'Certified Steel' mark to market and sell their products.
ResponsibleSteel certification applies to steelmaking sites, and to related sites that process raw materials for steelmaking, or that produce steel products. All ResponsibleSteel Certified Sites must meet the ResponsibleSteel International Production Standard’s Core requirements to achieve Site Certification. But we believe moving towards responsible steel production is a continuous journey. That’s why in addition to the Core requirements, sites can also be audited against four Progress Levels assessing progress on decarbonisation and responsible materials sourcing. Sites which obtain at least Level 1 for both decarbonisation and materials sourcing can market their steel products as Certified Steel.
Steel sites must first contract a recognised certification body and conduct a self-assessment to determine whether they are ready to proceed with certification. Stage 1 of the audit process then involves a review of this self-assessment, site documentation, and a media and stakeholder analysis by the auditors. Stage 2 involves an onsite visit and extensive stakeholder interviews conducted by the auditors.
Once the audits are complete, the auditors prepare the audit report and provide a certification recommendation. Our team and the ResponsibleSteel Assurance Panel review the report and the recommendation and suggest any amendments or clarifications needed. If approved, a certificate and public audit summary will be published on the ResponsibleSteel website. Certificates are valid for three years during which time sites must also pass a surveillance audit to ensure the site is making progress on any non-conformities found in the initial audit.
Independent research commissioned by ISEAL found that sustainability standards improve market access, profitability and production for certified businesses, and enhance reputation while reducing risk for manufacturers and retailers. Early business benefits related to sales and marketing were most frequently mentioned, followed by benefits on operations, procurement, stakeholder engagement and sector-wide change.
Our independent third-party certification programme is designed to provide businesses and consumers worldwide with confidence that the steel they use has been sourced and produced responsibly at all levels of the steel supply chain.
