About S20

Established in 2017, the S20 is one of the youngest engagement groups of the G20. Analogous to the G20, it has a non-permanent rotating secretariat and operates like a forum rather than as an organization.

Previous S20 cycles were held in:

  • Berlin, Germany in 2017 (Improving Global Health: Tools and Strategies to Combat Chronic and Communicable Diseases)
  • Buenos Aires, Argentina in 2018 (Food and Nutrition Security: Improving Soils and Increasing Productivity)
  • Tokyo, Japan in 2019 (Threats to Marine Ecosystems and Conservation of the Marine Environment – with Special Attention to Climate Change and Marine Plastic Waste)

The S20 supports the G20 by fostering an official dialogue with the scientific community and is normally led by the national science academy of the host country. The core purpose of the S20 Engagement Group is to present policymakers with consensus-based recommendations for the chosen topics of interest. These science-driven recommendations are formulated through task forces comprising international experts. To support and guide the task forces, a sherpa is appointed. Each task force focuses on one encompassing topic that is relevant to scientists, policymakers and society alike.

Over the course of a S20 cycle, each task force formulates a substantive policy paper with specific recommendations and implementable actions for the G20. These policy proposals form the basis of the S20 communiqué, that is officially presented to the G20 leaders for consideration.

The S20 summits are held annually, usually before the respective G20 summit.
