Global Circularity Protocol for Business - Version 1.0

The Global Circularity Protocol for Business (GCP) Version 1.0 is a voluntary, science-based framework designed to help companies measure, manage, and communicate their circularity performance. Developed jointly by WBCSD and the One Planet Network (hosted by UNEP) with input from more than 150 experts and over 80 organizations, it provides standardized metrics and practical guidance for reducing waste, cutting emissions, and improving resource efficiency across value chains. Piloted by leading companies, the GCP enables credible, comparable reporting and supports businesses in identifying circularity hotspots, enhancing accountability, and strengthening resilience. Announced at COP30, it marks a significant step toward harmonized global practices for circularity.
