The United Nations Sustainable Development Solutions Network (SDSN) mobilizes scientific and technical expertise from academia, civil society, and the private sector to support practical problem solving for sustainable development at local, national, and global scales. The SDSN has been operating since 2012 under the auspices of the UN Secretary‐General. The SDSN is building national and regional networks of knowledge institutions, solution‐focused thematic networks, and the SDG Academy, an online university for sustainable development.
