Global social injustice and inequalities remain deeply embedded in our globalized world, often explained as a consequence of the current economic structures and institutions. Therefore, there has been an increase in arenas that attracts mobilization of the global civil society to oppose the neoliberal economic globalization and combat social injustices and inequalities. The World Social Forum (WSF) is an example of an arena that emerged with these purposes. However, research shows that there are criticism regarding the character and function of the WSF. This literature study examines the reasons behind the criticism and compares them with the WSF’s charter of principles to see if the WSF is living up to its ideals. It also analyzes if the WSF’s principles are reflected in the 17 Sustainable Development Goals (SDGs) of the 2030 Agenda. This is done through a content analysis and within the framework of social justice and transnational public sphere. The study concludes that the WSF does not live up to its ideals because of a lack in organizational structure, exclusive and elitist character, and also the inequalities and inequities that are reinforced within the WSF. Moreover, the study shows that the WSF’s principles can be found among the 17 SDGs in the 2030 Agenda which can indicate that the WSF has had an indirect role in influencing global development policies.
