Ecology Generation (Template:Lang-fr) is, together with the Greens (Les Verts), the Independent Ecological Movement and Citizenship, Action, Participation for the 21st Century (CAP21), one of the four "green" parties in France. Founded by Brice Lalonde in 1990, upon the suggestion of François Mitterrand, it describes itself as a club with cross-party alliances of green-minded politicians and public servants.
The party, in alliance with The Greens obtained about 14% of the vote in the French regional elections, 1992; but the 1993 legislative election was disappointing for the Green-GE alliance, as it failed to win any seats and won only 7% (other ecologist parties brought the score up to 11%), when polls had given them up to 16%.
Noël Mamère was the movement's vice-president from 1992 to 1994, when he was excluded from the party and founded the Ecology-Solidarity Convergence, which later joined The Greens. Unlike many green parties, which are traditionally associated with the left-wing, Génération Écologie presents itself as a centre-right ecologist party, despite its early allegiance with the Socialist Party. Nicknamed 'The Blues,' after the traditional colour of conservatism, it has been associated with the conservative UMP since 2002, although the links between the two parties grew more tenuous after the French regional elections, 2004.
Génération Écologie has cooperated since the 2004 elections with several other movements that share its priorities. It has worked alongside various organisations, most prominently the Federalist Party, the Centre of Handicapped Democrats, and the Vanquish Unemployment Association.
