Some technologies needed are not yet available at scale, which limits our ability to take certain actions in the short term.
Continuous improvement efforts led Avient to initiate a targeted assessment of 460 suppliers and our 20 largest customers to assess carbon emissions data availability and reduction plans.
Our latest assessment identified that less than 50% of suppliers and customers have existing greenhouse gas commitments.

Our latest grades offer up
to 50% lower haze and reduced impact on the PET recycle stream
compared to previous grades.
Through this data, we create safety data sheets,
customer certification statements and product safety improvements.
Sustainability metrics represent 2019 data or
12-month approximate values based on available
data from reporting facilities and are often made in
reliance on third-party supplier information.
