Introduction

 

The objective of the SCS scheme is to enable approved firms to demonstrate sustainability management and performance through high quality independent 3rd party certification. This provides reliable information and data to enable construction stakeholders to make informed decisions that drives asset level sustainability performance and responsible sourcing.


Operating since 2009, the scheme is currently in its 9th Version. As part of CARES governance and the scheme accreditation to BS8902 it is subject to regular review and new versions are developed and introduced every 3 to 5 years.

 

Version 10 has been under development for the past two years and earlier proposals for changes to V9 of the scheme have been subject to substantive public consultation, including through; the CARES Sustainability Committee, stakeholder days across many different geographies, 1:1 meetings with interested parties, Scheme Manager, Auditor and CARES employee interaction with approved firms, a public 60 day consultation, and open invitation to feedback.

 

This consultation is for a final review of the following documents with the rationale for this stated:

• Scheme Guidance documents. These are new documents which contain the requirements within the Operational Assessment Schedules (OAS) as well as updated guidance, previously held within the Annex 1 Self-Assessment and Audit workbook. They are split into 3 versions: 1 for Steel Manufacturers (Steel Mills and Rolling Mills), 1 for Traders and 1 for Fabricators. To assist you in completing the survey links to Steel Manufacturers, Traders and Fabricators.
• Scheme Glossary. The Scheme Glossary is a new document which applies across the scheme which takes its content from guidance previously held in OAS, Annex 1 and from the newly developed Steel Standards Principles Glossary. 
To assist you in completing the survey link to Scheme Glossary.

The following Scheme documents are outside of the scope of this consultation for the rationale stated:

• The Scheme Operational Assessment Schedules. The content for the Scheme Operational Assessment Schedules is contained within the more detailed Guidance documents. Any changes to the Scheme Guidance documents will be reflected in the Operational Assessment Schedules series further to the consultation.
• The Scheme’s Annex 1 – Self-Assessment and Audit workbooks. These xls workbooks are based on the Scheme OAS and the Guidance documents which include information on credit scores and rating. Any changes to the Scheme Guidance documents will be reflected in the Annex 1 – Self-Assessment and Audit workbook further to the consultation.
• The SCS Scheme Manual defines the certification rules and application of them, as well as outlining the scheme governance requirements and has not changed.
• The procedures in operation at the time of the audit are documented and maintained in Annex 2 - Schedule of Operations, which is also not changing.

Benefits of v10


Certification to the Sustainable Constructional Steels Scheme enables construction sector clients and others stakeholders to gain confidence in the provenance and responsible sourcing management practices and performance of constructional steels from materials sourcing, steel production, steel products and fabrication.


Version 10 reflects latest expectations of the construction industry, leading practices in responsible and sustainable steel value chains and supports alignment and harmonisation across similar standards. It supports firms in meeting legal requirements and can be used to promote corporate and product responsible and sustainable practices and claims as defined in the Guidance.

Approved firms can use the framework of the SCS scheme to drive performance improvements and meet stakeholder expectations.
