The United Nations High Level Political Forum on Sustainable Development (HLPF) was established in June 2013 through a Resolution by the UN General Assembly as the main forum for sustainable development issues within the UN framework. Its establishment is one the main outcomes of the Rio+20 conference on sustainable development (see para 84 of the Rio+20 Outcome Document "The Future We Want"). The HLPF replaces the Commission for Sustainable Development, which was a functional Commission under the UN Economic and Social Council, established at the 1992 in the World Summit on Sustainable Development.
