Communiqué: S20 Brazil Statement 

The 8th edition of Science20 (S20), organised by the Brazilian Academy of Sciences (ABC) in 2024, centered around the theme "Science for Global Transformation" and encompassed five critical areas:

• Artificial Intelligence: Addressing ethics, social impact, regulation, and knowledge sharing.
• Bioeconomy: Advancing global sustainability efforts.
• Energy Transition Process: Emphasising renewable energy sources while considering social and economic implications.
• Health Challenges: Focusing on quality, equity, and access to healthcare.
• Social Justice: Promoting inclusion, alleviating poverty, and reducing inequalities.

S20 Brasil was structured in two significant phases: the Inception Meeting held in March and the S20 Summit in July, both in Rio de Janeiro. The primary goal of the summit was to finalise and approve thematic documents along with the official communiqué for S20 Brazil 2024. This pivotal gathering sought to synthesise insights from the March meeting and articulate actionable recommendations for the G20.

The resultant S20 Brazil 2024 Communiqué, titled "Science for Global Transformation," encapsulated these recommendations and was formally presented to G20 leaders in November 2024. This engagement illustrates a commitment to utilising scientific expertise as a foundation for transformative global action, inspiring collaborative initiatives that address today's pressing issues.

Theme: Science for Navigating Critical Transitions 
Communiqué: S20 Saudi Arabia Statement

In the 2020 edition, the S20 activities were coordinated by Saudi Arabia, under the theme “Future of Health: Navigating Critical Transitions”. Initially scheduled to be held in Riyadh, Saudi Arabia, the Science 20 (S20) meeting took place virtually on September 26 and mobilised invited researchers to collaborate with four task forces: Future of Health, Circular Economy, Digital Revolution and Connecting the Dots, the latter being responsible for interconnecting and synthesising the previous topics. At the 15th G20 Summit, the Academies of Sciences presented the joint statement “Perspectives: Science for Navigating Critical Transitions” to the G20 presidency of Saudi Arabia.
“The primary conclusion of the 2020 Science 20 (S20), representing the National Academies of Science of G20 nations, is that issues of planet and people must be viewed holistically and with full appreciation of their complexity and interconnectedness. This lesson was learned from a systematic examination of emerging critical global transitions in health, environment, and technology, punctuated by a real-time example of a globally disruptive event, the COVID19 pandemic. This viral pandemic laid bare the health, economic, social, and educational vulnerabilities of societies and exposed the lack of foresight that resulted in ill-equipped responses on multiple fronts.”

Place: Tokyo, Japan
Date: 6 March 2019
Theme: Threats to Coastal and Marine Ecosystems
Communiqué: S20 Japan Statement

The 2019 meeting was held in Tokyo and addressed marine conservation as a highlight of the document signed by the Academies of Sciences of the G20 member countries, through the specialised dialogue forum, S20, in a meeting held at the headquarters of the Science Council of the G20. The S20 group's recommendations were delivered to Japanese Prime Minister Shinzō Abe and presented at the G20 annual meeting in Osaka in June..
“A healthy coastal and marine environment is essential for the ongoing sustainable development of human society. The ocean is a large absorber of atmospheric heat and carbon dioxide, and provides a vital buffer against anthropogenic climate change. The ocean contributes to human well-being in many ways, such as providing protein from fisheries, maintaining various natural cycles and is also a source of recreation and spiritual comfort. However, coastal and marine ecosystems are also facing serious threats. There are major environmental concerns on a global scale, which include acidification, deoxygenation, warming and its associated sea level rise as well as frequent extreme weather conditions. High nutrient inputs and inflow of pollutants such as heavy metals and organic toxic materials deteriorate coastal environments. Accumulation of plastic waste in the ocean originating from both land and ocean is an emerging problem. Damaging fishing practices, including Illegal, Unregulated and Unreported (IUU), affect coastal and marine ecosystems. The role of science in minimising these impacts upon nature and society should not be understated.”

Communiqué: S20 Argentina Statement

The 2018 Science 20 (S20) meeting took place on 24 and 25 July, in Rosario, Argentina, and was attended by more than 400 people. On the occasion, issues relating to food and nutritional security, water resources and energy were discussed. At the end of the event, the declaration was approved guiding governments in the formulation of public policies to guarantee actions against hunger and malnutrition. The book produced in collaboration between the InterAmerican Network of Academies of Sciences and the Academies of Sciences of the Americas was also released, which deals with food and nutritional security on the American continent.
“Soil, water and energy are essential resources for ensuring food security in the world. Human pressures on soil resources are reaching critical limits. Main threats are erosion, loss of organic carbon, nutrient imbalances, salinisation and sodification, loss of biodiversity, contamination, acidification, compaction and urbanisation. In this context, the S20 affinity group makes the following specific recommendations for the sustainable management of soils: 1. Promoting good soil governance. 2. Promoting soil knowledge in specific areas. 3. Increasing international scientific cooperation programmes in the sustainable management of soil."

Communiqué: S20 Germany Statement

Science20 (S20) was created to act as the G20 engagement group for the area of science and technology. On 22 March 2017, representatives of Science Academies from the 20 countries with the largest economies in the world, which form the G-20, met at the Science 20 Dialogue Forum, in Halle, Germany, where they delivered to the German Chancellor, Angela Merkel, a document with recommendations for future global health management strategies. In the document, scientists address strategies for fighting infectious and non-infectious diseases that threaten individual well-being and harm health and the global economy.
“Communicable (infectious) and non-communicable (non-infectious) diseases seriously endanger individual wellbeing and global health, and threaten the global economy. Strong short- and long-term evidence-based strategies are needed. The G20 Academies of Sciences call for: (1) the strengthening of healthcare and public health systems, (2) applying existing and emerging knowledge, (3) addressing the broader social and environmental determinants of health, (4) reducing serious risk factors for disease through education and promotion of healthy life styles, (5) ensuring access to health resources globally, and (6) enhancing and extending robust strategies for surveillance and information-sharing. Furthering research is a prerequisite for providing knowledge and new tools to meet these challenges.”
