The European Federation of Green Parties is an umbrella organization of green parties in Europe. On February 21, 2004, the European Federation of Green Parties met in Rome to found a real party organization (i.e., not an umbrella organization, but a member organization). This new organization is called European Greens.
Prior to the founding of the European Greens, EFGP was one-half of the Greens-EFA group in the European Parliament.
The European Federation facilitates communication between member parties. At meetings it arrives at shared manifestos for European elections, and provides an opportunity for networking and the discussion of strategy. It also gives support to smaller or newer parties in order to strengthen them. For example, they did work in Spain to unify divided groupings in each region, and succeeded to an extent - two regions elected Green MPs to the Spanish Parliament.
As of 2004, the Federation includes 32 Green Parties in 29 European countries. See European Greens for detailed information on membership.
GreenParties are part of, but do not exclusively represent, a larger political movement to reform human governance to better fit the constraints of the biosphere — usually called the Green movement to contrast it from the electoral participation of the legally-registered Parties.
GreenParties are often formed in a given jurisdiction by a coalition of scientific ecologists, community environmentalists, and local (or national) leftist groups or groups concerned with peace or citizens rights.
GreenParties in Italy and France are part of the political pendulum and return to government with the success of the main parties of the left.
The Green movement encompasses the Greenparties of various countries, and relies on the ideals of the larger ecology movement, peace movement, conservation movement, environmental movement and general trend towards environmentalism.
Not all political ecologists or "Greens" are necessarily active in parties or Green politics.
Greens also often support traditional "left" socialist or "right" capitalist parties as part of a Red-Green Alliance or Blue-Green Alliance or to achieve some tactical purpose.
