The EEA now has 33 member countries and six cooperating countries. The European environment information and observation network (Eionet) is a partnership network of the EEA and the countries. The EEA is responsible for developing the network and coordinating its activities. To do so, the EEA works closely together with national focal points, typically national environment agencies or environment ministries. They are responsible for coordinating national networks involving many institutions (about 350 in all).
