While progress is made in many places to achieve the Sustainable Development Goals and to align economic, social and environmental progress globally; the overall speed and level of action is not sufficient to deliver on the targets set for 2030. The United Nations have hence launched the Decade of Action to speed up transformative change in the 2020s. This panel will discuss what can be learned from successful SDG implementation in different places to scale-up transformative action globally. What are common characteristics of successful SDG projects? What role do national governments, international organisations, business, science and civil society have to play to support effective SDG achievement? What impulses can the G20 give to kick-start the Decade of Action? How can the G20 help to operationalise the “leave no one behind principle” and support SDG achievement in Least Developed Countries? How can the G20 support effective global SDG monitoring by pioneering best practice and supporting other countries?
