Responsible Sourcing

BES 6001 provides a common benchmark for all construction products to demonstrate their responsible sourcing credentials. The full listing of products certified to BES 6001 is available at 

The concrete industry was the first industry to link its sustainable construction strategy to BES 6001 and has produced the publication 'Specifying Sustainable Concrete' to support the implementation of the standard.       

Performance indicator

Percentage of production certified to BES 6001 responsible sourcing standard

Providing evidence of the responsible sourcing of building products and materials continues to be crucial with the need to demonstrate compliance with a recognised responsible sourcing scheme, certified by a third party. Our indicators report the proportion of concrete and constituent materials production that are currently certified to BES 6001.

During 2018, certification of concrete products to BES 6001 reached 91% of production tonnage. Over 90% of this certified tonnage achieved a performance rating of ‘Very Good’ or ‘Excellent’. Of key interest to construction being rated to BREEAM assessment schemes, is  a rating of responsible sourcing used in calculating credits under this aspect.

This is now demonstrated by the Responsible Sourcing Certification Scheme (RSCS) score which is shown on each product BES6001 certificate available at and is often higher than the generic score allocated to BES 6001 in BREEAM.

The majority of certified concrete production attracts a RSCS score of 7 -currently the highest value for any scheme.  

The 2020 target for BES 6001 certification is 95% and the aspiration of the concrete industry is to achieve 100%.

The proportion of concrete raw materials certified to BES 6001 in 2017 is shown below:

UK Material Sector % BES 6001 Certified
Aggregates 94%
Cement 100%
BAR Mills* 86%
BAR Fabricators* 98%
*To Eco-reinforcement BES 6001 based scheme
