The present Report was prepared to inform the deliberations of Member States at the High-Level Political Forum on sustainable development (HLPF) in July 2015, including with respect to the scope and methodology of a Global Sustainable Development Report. It is a complement to the prototype GSDR published in 2014 for the second session of the HLPF.
The content of the report is based on the knowledge and expertise of more than 500 contributing scientists and many experts from more than 20 United Nations agencies. The chapters are examples of different analytical approaches that future editions of the GSDR could take to informing discussions on sustainble development at the HLPF with the latest science. Conforming to the mandate given in Rio+20, the chapters do not seek to produce new knowledge but to reflect existing documentation and assessments and turn them into simple, coherent "digests" that can inform decision-making.
