Sharing our Corporate Social Responsibility requirements with our suppliers


We aim to create stable and reliable with our suppliers based on trust and shared values.  

The Solvay Way – “doing business, being responsible” – is our approach to Corporate Social Responsibility (CSR). The Solvay Way is fully embedded in the global Solvay Purchasing Process, and we evaluate our progress annually in three areas. With the Solvay Way, we ensure that we:


Define prerequisites and integrate them into the supplier selection process


At the Procurement function, we apply a single methodology worldwide to qualify, select and evaluate suppliers for each tender. We assess suppliers’ CSR level through a Solvay questionnaire. Furthermore, the template for the contracts we send out to suppliers includes a CSR clause and a reference to the Supplier Code of Conduct. We also invite suppliers to have an assessment performed by a third party certified by the Together for Sustainability association.


Evaluate buyers’ CSR performance


At Solvay, we regularly organize specific CSR training sessions for buyers. We integrate sustainability into their day-to-day relationships with suppliers, for example through the Every Buyer Every Visit Programme.


Manage and assess suppliers’ CSR performance and optimize relationships  


We continually assess suppliers’ performance and recognize the top performing suppliers.  

The Solvay CSR questionnaire allows us to get a good understanding of a new supplier’s CSR maturity. Third-party assessments allow us to obtain objective and transparent knowledge of a supplier’s CSR performance, especially for our critical suppliers.

If needed, corrective actions are requested and followed up.
