Key contribution

Due to our belief in using eco-friendly building materials, Saint-Gobain policies encourage conformity to the European Union’s REACH Regulation on avoiding the use of Substances of Very High Concern (SVHC) above 0.1% in weight.


To encourage the use of products and materials for which life-cycle information is available and that have environmentally, economically, and socially preferable life-cycle impacts. To reward project teams for selecting products for which the chemical ingredients in the product are inventoried using an accepted methodology and for selecting products verified to minimize the use and generation of harmful substances. To reward raw material manufacturers who produce products verified to have improved life-cycle impacts.

Detailed requirement

Option 1. Material ingredient reporting (1 point)

The project has to use at least 20 different permanently installed products from at least 5 different manufacturers that demonstrate the chemical inventory of the product to at least 0.1% (1000 pm).

Option 2. Material ingredient optimization (1 point)

The products must document their material ingredient optimization for at least 25%, based on cost, of the total value of permanently installed products in the project. One of the methodologies recognized by LEED is the REACH optimization. When the product contains no ingredients listed on the REACH Authorization or Candidate list, it is valued at least 100% of cost for the calculation.

Option 3. Product manufacturer supply chain optimization (1 point)

Manufacturers have to be engaged in validated and robust safety, health, hazard, and risk programs with independent third party verification of their supply chain.

Additional option:

Products sourced (extracted, manufactured, purchased) within 160km of the project site are evaluated at 200% of their base contributing cost.

Our contribution

Option 2

Calcium Sulphate Dihydrate (EINECs number 231-900-3) has full registration under the REACH regulations through a joint submission. According to this registration, Calcium Sulphate is not classified as hazardous under The Classification, Labelling and Packaging (CLP) Regulation.
As per company policy, our gypsum products and solutions as well as packaging contain no Substances of Very High Concern (SVHC) in concentrations higher than 0.1% in weight under the terms of REACH. Publications and updates are followed closely.

Option 3

Saint-Gobain Gyproc commits to high standards of safety, health, hazard, and risk programs linking with the supply chain, as per our Chairman and CEO’s engagement letter and our Charter for Environmental Health & Safety.
