The Council of Europe/Council of the European Union
Explanation: vulgo: European Council (but I've been told off for writing that). The European Parliament would be das europäische Parlament or Europaparlament.
Referenzrahmen could be anything - guidelines, informal/formal standards... but if it's set in quotation marks, chances are this is an official document.
I'd do an internet search, maybe on europa.eu.int (or the EU Consilium site), and see what you come up with.
