SOLIDAR is a European and worldwide network of Civil Society Organisations (CSOs) working to advance social justice through a just transition in Europe and worldwide. With over 50 member organisations based in 26 countries (19 of which are EU countries), member organisations are national CSOs in Europe, as well as some non-EU and EU-wide organisations, working in one or more of our fields of activity.
