A mandatory Self-Assessment will ensure the quality and traceability of manufactured products, proper wastewater, and emission management as well as worker safety. Up until now, the ECO PASSPORT has had a mandatory CAS-number screening and laboratory analysis with voluntary options for Self-Assessment and On-Site Visit. While the On-Site Visit will remain optional for the time being, the Self-Assessment will become a mandatory requirement for every customer who has not yet passed it for their production sites as of April 2023.
