The Sustainable Development Goals (SDGs) are a universal set of seventeen goals and 169 targets, with accompanying indicators, which were agreed by UN member states to frame their policy agendas for the fifteen-year period from 2015 to 2030. Written by three authors who have been engaged in the development of the SDGs from the beginning, this book offers an insider view of the process and a unique entry into what will be seen as one of the most significant negotiations and global policy agendas of the twenty-first century. The book reviews how the SDGs were developed, what happened in key meetings and how this transformational agenda, which took more than three years to negotiate, came together in September 2015. It dissects and analyzes the meetings, organizations and individuals that played key roles in their development. It provides fascinating insights into the subtleties and challenges of high-level negotiation processes of governments and stakeholders, and into how the SDGs were debated, formulated and agreed. It is essential reading for all interested in the UN, sustainable development and the future of the planet and humankind.
