Det anslås, at der årligt ville kunne spares 200 millioner euro af EU's skatteborgeres penge, hvis det blev besluttet at oprette Parlamentets hovedkvarter i Bruxelles, ikke blot på grund af den iboende omkostningsbesparelse, men også fordi det ville lette arbejdet mellem institutionerne.
It is estimated that over 200 million euros would be saved annually from the European tax payer's money if it was decided to establish the Parliament's headquarters in Brussels, not only due to the inherent cost reduction, but also by facilitating interinstitutional work.
