Get Cradle to Cradle Certified™

Development of Version 4.0

We are pleased to announce work is underway to create the next version (v4.0) of the Cradle to Cradle Certified™ Product Standard. The standard revision process began in June of 2014 and is anticipated to be completed in early 2019. The process engages a variety of stakeholders, including our five technical advisory groups and the C2CPII Stakeholder Advisory Council, and will include public comment periods. An overview of the standard development process and estimated timeline for each step can be found in the Summary of the Process for Revision of the Cradle to Cradle Certified Product Standard and the Policy for the Maintenance of the Cradle to Cradle Certified Product Standard. Announcements regarding the public comment period will be sent to our mailing list.

The Cradle to Cradle Certified™ Product Standard is governed by an independent Certification Standards Board (CSB). The CSB is a nine member Board composed of industry leaders from Cradle to Cradle certification holder companies, Cradle to Cradle Certified assessors, and topical experts, and is chaired by the Institute's Vice President of Science and Certification. The CSB is the decision-making body responsible for revising and updating the standard, and adjudicating appeals related to product certification, as necessary.

Guiding Principles

  • Fully manifest the integrity and vision of Cradle to Cradle® principles to ensure that application of the standard measurably and significantly improves the condition of the earth’s environment and quality of life for all people.
  • Always strive for simplicity and clarity in the structure, language, and content of the standard.
  • Make adherence to the standard feasible for a wide range of participants.
  • Avoid ambiguity and inconsistencies by basing the standard on metrics that can be uniformly assessed and audited.
  • Seek to fully leverage respected scientific networks and professional resources to ensure the standard reflects the most current and relevant scientific thinking and practice.
  • Use the revisions process to engage a variety of stakeholders in the standard’s development and the Cradle to Cradle Certified Products Program.


  • Create a thoroughly improved version of the Cradle to Cradle Certified Product Standard within a realistic timeframe.
  • Create an effective structure for accomplishing tasks related to the revision.
  • Attempt to harmonize with globally recognized standards, systems, and practices wherever relevant and possible in order to amplify recognition and adoption of the standard.
  • Maintain oversight to ensure revision work is coordinated and deliverables meet deadlines.
  • Seek and manage stakeholder input to achieve the greatest possible improvement of the standard.
  • Conduct the revision process in a transparent manner that invites and utilizes positive input to maximum advantage in improving the standard.

Five advisory groups, one for each category of the Cradle to Cradle Certified™ Product Standard, have been formed by the Certifications Standards Board to provide expert guidance as part of the version 4.0 development process. Interested individuals were invited to apply during an open application process held from March 1 to April 15, 2014. Of the 150 individuals that applied, 78 were selected based on relevant technical expertise, stakeholder group, and geographic location. Final revisions to the Cradle to Cradle Certified Product Standard will be determined by the Certification Standards Board based on recommendations made by the advisory groups.
