Turning ratings into learning

At Solvay, we care about performing strongly on both financial and extra-financial indexes. Positive ratings help us create a long-term trusting relationship with our stakeholders, and the feedback from the agencies has a real impact on the Group’s priorities, as it connects directly with our stakeholders’ key concerns.

We will no longer actively participate in RobecoSAM’s DJSI assessment.
