The refined Hierarchy introduces key improvements that enhance the Hierarchyâs effectiveness as a leading tool for developing Zero 91²Ö¿â policies, programs and strategies worldwide. âThese updates provide essential insights to address current issues, including chemical recycling and working toward a circular economy,â said Gary Liss, Chair of the Zero 91²Ö¿â Certification Committee
This update reinforces the Zero 91²Ö¿â Hierarchy as a critical resource in advancing sustainable material use and waste reduction efforts globally. By adopting Version 8.1, ZWIA aims to provide greater clarity and direction for organizations and communities working toward a Zero 91²Ö¿â future. âThe Zero 91²Ö¿â Hierarchy provides a critical understanding of policies to ensure global alignment with the term âZero 91²Ö¿ââ,âsays Jamie Kaminski, Committee Chair of the Zero 91²Ö¿â Hierarchy Working Group.
âConserving resources is our goal; the hierarchy provides a model,â says Richard Anthony, President of ZWIA.
Key updates in Version 8.1 include:
- Enhanced language in the guiding principle of Do Not Export Harm, to ensure that harmful materials are not sent to regions or facilities that cannot properly handle them, with regard to environmental and health standards.
- Addition of a new principle, Do No Harm, to guide organizations in minimizing the negative social and environmental impacts of materials and discards throughout their lifecycle.
- Technical refinements to definitions surrounding circular economy, closed-loop systems, composting, and recycling, ensuring clarity and consistency in application.
This update was developed in collaboration with leading international Zero 91²Ö¿â organizations, including Zero 91²Ö¿â International Alliance (ZWIA), Zero 91²Ö¿â Canada (ZWC), Zero 91²Ö¿â British Columbia (ZWBC), Zero 91²Ö¿â Europe (ZWE), GAIA, and the Energy Justice Network.
