At the end of the 1980s, the group was involved in the formation of a Greek Federation of Ecological and Environmental Organisations. In 1990 the federation transformed into a political party, the Alternative Ecologists), which was beset with problems and proved to be short-lived. The collapse of the party caused a decline in membership for the larger groups, while the smaller and newer groups ceased to exist. The Thessaloniki group managed to survive but with much reduced membership. In 1995, members of the group founded Antigone, an information and documentation centre on racism, ecology, peace and non-violence. In the mid 1990s a green-left list was organised to participate in local elections. The list had a strongly anti-nationalistic stance during a period in which nationalistic sentiments were stirred by the name and flag of Greece's new neighbour, the Republic of Macedonia, as well as the war in Bosnia-Herzegovina. In local elections in 1998, the list received the support of Synaspismos, the Greek Party of the European Left, and had one member, Tremopoulos, elected to the Prefecture Council.
