Blue Green Alliance

A Blue–green alliance describes either an or coalition between "blue" conservative parties and green parties, or "blue" labor organizations, such as labor unions, and environmental organizations such as green parties. "Blue-Green" can also refer to a right-tendency within green parties based around green conservatism.

The Green Party of Ontario and to a lesser extent, the Green Party of Canada are considered "blue–green" because they are more economically centrist or even right wing. See Blue Greens.

The Second Cabinet of Prime Minister Mirek Topolánek, member of the liberal-conservative Civic Democratic Party, included the Czech Green Party.

Several governments of Finland have included both the liberal-conservative National Coalition Party and the Green League, including the incumbent cabinet of Prime Minister Jyrki Katainen.

On 13 June 2007, following the 2007 general election, the Irish Green Party became a minor coalition partner to the conservative Fianna Fáil and the (now-defunct) liberal Progressive Democrats, entering government for the first time in the Greens' history. The Green Party remained a coalition partner until the 2011 general election, when the Greens lost their representation in the Dáil Éireann.
