The Global Geoparks Network (GGN), of which membership is obligatory for UNESCO Global Geoparks, is a legally constituted not-for-profit organisation with an annual membership fee. The GGN was founded in 2004 and is a dynamic network where members are committed to work together and exchange ideas of best practise and join in common projects to raise the quality standards of all products and practises of a UNESCO Global Geopark. While the GGN as a whole comes together every two years, it functions through the operation of regional networks, such as the European Geoparks Network that meets twice a year to develop and promote joint activities.
