In this chapter the focus lies mainly on a market comprising 20,000 people working in trade federations. Two showcases are presented: “Interest groups in agriculture policy. EU and Romania” and “Interest groups in energy policy. EU and USA”. Special parts are allocated to present the branding of EU federations, but also to provide the reader with the link between EU federations and corporate. A detailed list of approximately 500 European associations, segmented by their EU policy interests, is presented.
