The Global Circularity Protocol for Business (GCP) has been launched to accelerate the transition to a circular economy by providing a global framework for measuring, managing and communicating an organisation’s circular performance and its impacts. Developed by the World Business Council for Sustainable Development (WBCSD) in collaboration with the UNEP-hosted One Planet Network (OPN), the GCP enables organisations to embed circularity at the heart of strategy and operations.

The Protocol offers a step-by-step approach to frame, prepare, measure, manage and communicate progress, enabling organizations to track material flows, assess impacts across climate, nature, equity and business performance, and communicate results through comparable, decision-useful information.

GCP v1.0 has been co-developed by WBCSD and UNEP’s One Planet Network, with guidance from the Business, Policy and Science Advisory Committees, and with input from over 150 experts across 80 organisations.
