How Cradle to Cradle Certified Version 4.0 was developed.
The Cradle to Cradle Products Innovation Institute developed Version 4.0 of the Cradle to Cradle Certified Product Standard through a multi-stakeholder process informed by diverse technical subject matter experts, leading manufacturers, independent assessors, and other market representatives serving on the Institute’s Standards Steering Committee, as well as its Stakeholder Advisory Council and Technical Advisory Groups.
Drafts of Version 4.0 were made available for public comment during two separate review periods, and the standard has been tested in the market through the Cradle to Cradle Certified Version 4.0 Pilot Program. Eight market-leading companies have participated in the program by working to certify products to draft requirements of the new standard.
Public comment drafts of the Cradle to Cradle Certified Product Standard Version 4.0 and reference documents are available here.
The Cradle to Cradle Products Innovation Institute will begin accepting new applications to certify products to the Version 4.0 standard in July 2021.
