The level you start with depends on your current chemical management practices and your goals for improvement. Here is a brief guide to help you decide:

  • Level 1: This level is ideal for facilities new to chemical management or those looking to establish a basic understanding and implementation of ZDHC guidelines. It focuses on awareness and initial implementation steps.
  • Level 2: Suitable for facilities that have already implemented basic chemical management practices and want to demonstrate continuous improvement. This level includes a performance review and deeper insights into industry best practices.
  • Level 3: This level is best for facilities aiming to position themselves as leaders in sustainable chemical management. It involves an on-site review focusing on advanced practices to reduce risks and drive transparency across the value chain.
