The UNECE International PPP Centre of Excellence has as its core vision the implementation of PPP solutions to promote the United Nations Sustainable Development Goals (SDGs). One of its core functions is to advise governments in their project preparation, more specifically, how these projects can contribute to achieving the SDGs by putting people first through improved access to services, and by building more resilient infrastructure that are easily replicated in other regions and countries. The UNECE has gathered a number of cases studies from different sources public sector, NGOs, academia and the private sector. This Compendium collects 30 case studies from all over the world covering a wide variety of sectors from water to energy, and roads to agriculture. Publication Date: 01.04.2016
