The Framework Standard for Responsible Sourcing of Construction Products provides a holistic approach to managing a product from the point at which component materials are mined or harvested, through manufacture and processing.


Responsible Sourcing of Construction Products is demonstrated through an ethos of supply chain management and product stewardship and encompasses social, economic and environmental factors. It addresses aspects such as stakeholder engagement, labour practices and the management of supply chains serving materials sectors upstream of the manufacturer.

The BES 6001 Standard


The BES 6001 standard focuses on individual materials or products, which means that it’s the materials that the company has submitted for evaluation that are covered by the certification, not the organisation itself. A company may sell some products that are certified, whilst still selling others that have not yet been assessed.

The standard is broken down into three sections:
• Organisational Management Requirements
• Supply Chain Management Requirements
• Requirements Related to the Management of Sustainable Development

The standard asssesses the management practices of the organisation seeking certification, and also the nature, sources and make-up of the various component materials in the product.

To meet this Standard, organisations must satisfy certain compulsory elements. In addition, there are higher levels of compliance that can result in a higher performance rating being awarded. This Standard also provides a route to gaining credits under the BREEAM family of certification schemes.


V4.0 of the BES 6001 Standard


Following public consultation, version 4.0 of the BES 6001 Standard has been published and is available for certification.  V4.0 has enhanced emphasis on social aspects, sustainable procurement and supply chain engagement and additional environmental themes including biodiversity and site stewardship. Requirements have also been introduced to award science-based target setting and to encourage continuous improvement. The scoring structure also enables manufacturers to focus on criteria material to their organisations and products.
