Tomorrow is the International Day of Cooperatives. To celebrate it, the international cooperative movement is showing how those enterprises promote the United Nations Sustainable Development Goals (SDGs). ‘Co-operatives: the power to act for a sustainable future' is the slogan of the campaign that emphasizes our contribution to the goals. Industrial and service cooperatives – be they worker cooperatives, social cooperatives or self-employed producers' cooperatives - are crucial allies in the effort to achieve these goals.
