PGS Basics

Participatory Guarantee Systems (PGS) are revisiting the way organic certification started a few decades ago. At the same time, many PGS have existed for over 40 years. The development and professionalization of the organic sector, accompanied by increased international trade has called for third party certification to become the norm in most developed organic markets; nevertheless, PGS have never stopped to exist and serve organic producers and consumers eager to maintain local economies and direct, transparent relationships. 

Thousands of organic producers and consumers are now verified through PGS initiatives around the world. Although details of methodology and process vary, the key elements and features remain consistent worldwide.
