Fixed row] (1.4) State the end date of the year for which you are reporting data. Parameters used in the IEA STEPS (Stated Policies Scenario) included measurable factors that may have a financial impact on Avient’s business. For those that don't use municipal water or do but use additional sources, that is likewise tracked in our environmental tracking platform using the same approach as state previously.
