What is an RCE?
Regional Centers of Expertise (RCEs) are designed to implement these ESD initiatives. 
An RCE is a network of existing formal, non-formal and informal organizations that facilitate learning towards sustainable development in local and regional communities.
A network of RCEs worldwide constitutes the Global Learning Space for Sustainable Development with each RCE translating global objectives into the context of the local communities in which they operate. RCEs think globally but act locally and are the best keepers of knowledge about sustainability challenges in their home regions.
The success each RCE achieves on the local level is brought to scale through the global RCE Network. Local knowledge, expertise, and best practices are shared globally through the network and are able to be adapted and applied successfully in other regions.
 As of March 2015, the United Nations University officially acknowledges 136 RCEs worldwide.
