The World in 2050 (TWI2050) was established by SDSN Partner, International Institute for Applied Systems Analysis (IIASA) to provide scientific foundations for the 2030 Agenda. It is based on the voluntary and collaborative effort of more than 60 authors from about 20 institutions, and some 100 independent experts from academia, business, government, intergovernmental and non-governmental organizations from all the regions of the world, who met three times at IIASA to develop pathways toward achieving the SDGs. Presentations of the TWI2050 approach and work have been shown at many international meetings including the United Nations Science, Technology and Innovation Forums and the United Nations High-level Political Forums. Two important meetings were held, one focusing on governance organized by the German Development Institute (DIE) in Bonn, Germany and the other on regional perspectives organized by the Stockholm Resilience Centre (SRC) held in Kigali, Rwanda.

This report examines the current trends and dynamics that promote and jeopardize the achievement of the SDGs. It presents the TWI2050 framework, the integrated pathways which harness the synergies and multiple benefits across SDGs, and approaches to governing this sustainability transformation. TWI2050 identifies six exemplary transformations which will allow achieving the SDGs and long-term sustainability to 2050 and beyond:
