Sustainable Development Goals (SDGs) have come into effect since January 2016, bringing about a growing momentum towards upholding development and integrating it within good governance efforts. In this context, it is worthwhile to look at the SDGs from the more regional perspective of the Western Balkans, given that the region shares similar political and structural socio-economic challenges. However, this extremely ambitious programme, with 17 goals and 169 targets cannot be attained and implemented by national governments alone; it requires growing partnerships between governments, CSOs, the private sector and academia. For that reason, the discussion of the roles and responsibilities that different stakeholders should take remains critical. The aim of this policy brief, prepared in the framework of the regional project “Western Balkan CSOs for Global Development”, is to expose the current situation of CSOs involvement in localizing SDGs across the region in order to advocate for a meaningful involvement of civil society in the process. The policy brief is available for download here.
