Philanthropic organizations are playing an increasingly prominent role in supporting the international sustainable development agenda. Many are early embracers who have been aligning their planning and grant strategies to the SDGs. According to the Foundation Centre, the total foundation SDG Funding worldwide in 2016 has reached over USD $112 billion. Philanthropic organizations can contribute to the implementation of the 2030 Agenda for Sustainable Development in many ways. As advocates, they can support awareness raising through the integration of SDGs into their programming efforts and through thought leadership of collective platforms; as impact drivers, they can catalyze change and generate impact through big bets, collective action, cross-SDG partnerships; and as innovators, they exhibit a great willingness to test new ideas, adopt innovative approaches, forge new coalitions3 and help de-risk investments. Yet, there is significant potential to further scale up philanthropic engagement in SDG implementation.To review and discuss ways to strengthen partnerships with philanthropic organizations to accelerate SDG implementation, the Division for Sustainable Development Goals (DSDG) at the United Nations Department for Economic and Social Affairs (UN DESA) and the United Nations Office for Partnerships (UNOP), in collaboration with the SDG Philanthropy Platform, the European Foundation Centre, Synergos and the United Nations Foundation, will host, on 16 July 2019, a special event during the ministerial segment of the High Level Political Forum on Sustainable Development (HLPF) under the auspices of ECOSOC. The main objective of the special event is to create a dedicated space at the margins of the 2019 HLPF under the auspices of ECOSOC to discuss current models of philanthropic engagement to implement the 2030 Agenda and identify opportunities to scale up philanthropic leadership and transformational action to further accelerate SDG implementation. The event will also serve as an opportunity to gather momentum from the philanthropic sector in the lead up to the SDG Summit in September 2019, where Heads of State and Government will meet for the first time under the auspices of the General Assembly after the first four-year cycle of HLPF to assess progress in SDG implementation.
