Avient's Human Rights Policy

Sustainability commitments are generally not just focused on creating a better planet – they can also involve health & human safety, and human rights. Supporting employees with basic human rights and avoiding discrimination.   We typically analyze raw material suppliers through EcoVadis – who evaluates an organization based off 21 different sustainability topics that are categorized into environment, labor and human rights, ethics, and sustainable procurement.

We’ve worked with numerous customers who have grappled with these same questions, applying our dedicated design and color resources together with our materials and formulation expertise, to balance user experience with competitive differentiation and the practical concerns of manufacturing. By many estimates, our sense of vision represents up to 80% of all human experience today.
