In September 2015, the 193 United Nations Member States adopted the 2030 Agenda for Sustainable Development and the Sustainable Development Goals (SDGs). The UN Resolution 70/1 adopting the 2030 Agenda includes a pledge that “no one will be left behind” as well as commitments to prioritize the poorest and most marginalized. This UNDP discussion paper 'Sustainable Development Goals: Sexual and Gender Minorities' presents evidence of the marginalization and exclusion experienced by sexual and gender minorities in the context of the SDGs. The paper also discusses promising policy and programme approaches to protect the human rights of sexual and gender minorities and strengthen their inclusion in sustainable development, with attention to the potential role of philanthropies, development assistance providers and United Nations development system.
