EU agencies are distinct bodies from the EU institutions – separate legal entities set up to perform specific tasks under EU law.
Decentralised agencies contribute to the implementation of EU policies. They also support cooperation between the EU and national governments by pooling technical and specialist expertise from both the EU institutions and national authorities. Decentralised agencies are set up for an indefinite period and are located across the EU.
Agencies have been set up to carry out very specific technical, scientific and management tasks within the framework of European Union’s Common Security and Defence Policy.
