Green Party on the political compass
The US Green Party pairs strong environmental regulation and social spending with socially liberal positions. It lands on the left-libertarian side of the map, left of the Democrats.
Economic -5.0, social -3.0. That point lands in Libertarian Socialism.
Libertarian socialism wants common ownership without a central state: unions, councils, or communes would run production. It is left economically and clearly libertarian socially.
