Clean Production Action offers the most advanced training available for individuals interested in becoming licensed Authorized GreenScreen Practitioners. An Authorized GreenScreen Practitioner is a professional with the scientific expertise and training to perform high quality GreenScreen assessments for his or her registered organization.

This training program offers technical professionals – product designers, engineers, toxicologists, environmental health and safety experts, chemists, etc. - a unique opportunity to strengthen their professional portfolio while simultaneously helping their companies lead the way through the design of products that are safer for humans and the environment. As the need for alternatives assessment increases globally, in-house expertise in applying chemical hazard assessments will be an important measure of success and competitive advantage in this field.

What does the Authorized GreenScreen Practitioner Program® include?

  • Experience evaluating and using a wide variety of data sources to develop robust chemical hazard assessments
  • Personalized coaching
  • Hands-on experience performing GreenScreen assessments
  • Small workshop format

"Having completed this class, I realize just how well conceived and rigorous the GreenScreen actually is. This course has opened my eyes to the nuances and resources associated with assessing chemicals. As a result of taking this class I am an even more fervent advocate for using this tool as a powerful aid in identifying safer substitutes that we can reasonably assume will limit future need for replacement because of hazard.”

--Mark Snyder, Minnesota Pollution Control Agency
