Thomas M. Dietz, "Similar but Different? The European Greens Compared to Other Transnational Party Federations in Europe," Party Politics, 6 (April 2000), 199-210.

First Paragraph:

In June 1996, the transnational alliance of green parties in Europe, the European Greens, held a congress for the first time in 5 years. Together with far-reaching intra-organizational reforms implemented previously, this congress had the effect of making the European Greens more intensely perceived by the public. However, in the literature on European parties (Tsatsos, 1994; Jansen ,1995, 1996b: 321-3; Hix and Lord, 1997), the European Greens are still hardly recognized as being comparable to other European party federations. But are they really that different?

Table 3; The degree of interaction of the transnational party federations (October 1998)

Last Paragraph:
Although their degree of interaction is still less than that of other party federations in Europe, and in spite of the fact that the greens do not have an EU party federation, one cannot claim convincingly that the greens are too different for meaningful comparison with the other party federations. Within their existing structures they are able to carry out the same tasks as the EU-centred party federations of other European party families.
