Global governance

The Global Governance Committee (GNGC) was established in 2013 as the highest-level strategic body responsible for overall service definition, sustainability and long-term strategy. This includes formulating and recommending service governance principles and policies. It was set up as a result of the ever growing deployment and use of the service, and the community requesting a firmer basis for operations and governance worldwide.
The GNGC consists of six representatives of the regions where the service is available, appointed by the community for a two-year mandate. The committee meets regularly and is supported by GÉANT staff.
