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 (20 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. 

The network is brought together by its shared values of solidarity, equality and participation.

How we work

SOLIDAR voices the concerns of its member organisations to the EU and international institutions by carrying out advocacy actions, project management and coordination, policy monitoring and awareness-raising across its different policy areas.

Our vision

SOLIDAR’s vision is a world defined by solidarity, peace, social justice, and sustainable development, organised in a social contract that guarantees universal human rights and freedoms, decent work, and a decent life for all.

We regard social justice as the equal distribution of wealth, knowledge, income, and power within our global societies, ensured access to universal and quality social services, lifelong and life-wide learning, decent work, social protection, and a decent life for all expressed through a new social contract and in the form of a truly social citizenship. Sustainability is the way in which we achieve social justice while respecting the planetary boundaries in an economic system that puts people and planet first.

Our mission

SOLIDAR’s mission is to support our members in their work to achieve our vision at the national, European, and international level through the formation of alliances, coordination of collective actions, advocacy work, and policy influence, exchange of experiences, and access to funding and opportunities.

We regard Just transition as the guarantee that the transformation processes and drastic structural adjustments that are needed to meet the climate emergency, the digital revolution and tackle the continued structural gender inequalities and reoccurring social and economic crises, are being implemented taking the needs and rights of affected present and future communities into consideration. This is done through processes of social and civil dialogue that guarantees both social justice and sustainable development. SOLIDAR voices our members’ concerns and advocates for their priorities at any relevant opportunity before European institutions and stakeholders, providing our members with the ability to shape the debate at the EU level and engage with increasingly important decision-making. In so doing, we constitute a counterweight to authoritarian, nationalistic, and right-wing populist forces, as well as to conservative and neoliberal interests.
