What is CSR to Sioen?

At Sioen, Corporate Social Responsibility - all the actions we set intended to have a positive influence on the world - is a source of innovation, competitive advantage and value creation for all stakeholders. It is an integral part of our company strategy, and it is translated since decades in our company slogan “protection through innovation”, making people’s lives better. We’re using the triple bottom line and the UN SDGs as guidance in our operations, our decision-making and priority setting. Our actions are translated into certificates, audits, memberships as well as awards.
