The papers in this special issue are relevant to our understanding of Public Private Partnerships (PPPs) as a policy tool to achieve the United Nations 2030 Agenda for Sustainable Development across the world. The special issue sparks a new debate on the meaning of and conditions for PPPs as a policy tool, with a specific focus on the role that review and monitoring frameworks, regulations and incentive structures play in attracting PPPs investments and at the same time reinforcing the SD commitments of the government. The special issue emphasises the fact that the responsibility for achieving SD is a global one with the immense value of PPPs as a policy tool to further public policies in a wide range of fields, such as the national industrial policy, educational policy, reducing unemployment, improving employment conditions, support for small businesses, local development which in equal measure supports the realization of the Sustainable Development Goals (SDGs).
