The voluntary and non-binding Guidelines for Effective Philanthropic Engagement (“the Guidelines”) aim at facilitating collaboration between foundations and governments, with the objective of improving development outcomes. The Guidelines capture emerging good practices and key messages of foundations on how they view their relationships with governments. Foundations have identified three pillars critical to making their engagement with governments more effective: Dialogue, Data and information sharing and Partnerships. The Guidelines were developed under the leadership of the OECD Development Centre’s Network of Foundations Working for Development (netFWD), together with the Worldwide Initiatives for Grantmaker Support (WINGS), the European Foundation Centre (EFC), UNDP, Stars Foundation and the Rockefeller Foundation.
