On May 18–19, 2026, in Paris, the Science 7 (S7) brought together the national science academies of France, Canada, Germany, the United States, Italy, Japan, and the United Kingdom in the lead-up to the G7 Summit of Heads of State and Government in Evian from June 15-17. Organized by the Académie des sciences, the S7 is a scientific dialogue designed to inform international policymaking with the best-available scientific evidence.

For the 22nd consecutive year, the participating academies jointly prepared statements offering independent, science-based recommendations for G7 leaders.
“As global challenges accelerate, it is more important than ever that world leaders have access to the best-available knowledge to inform decisions about our shared future. This year’s Science 7 priorities – large satellite constellations, the global Arctic, and brain and mental health – address urgent and strategic issues that warrant serious attention in upcoming G7 discussions.” – Françoise Baylis (FRSC), RSC President
“The RSC has worked collaboratively with the other G7 Academies in developing these statements to reflect the best science available from across Canada and around the world. The importance of bringing forward expertise to inform international discussions has never been greater, and we are pleased to get this information in front of decision-makers ahead of the G7 summit.” – Andrew Weaver (FRSC), Vice-Chair of the RSC International Committee

View the three statements
Large Satellite Constellations: Prospects and Challenges
Perspectives from Peter G. Brown (Western University), Topic Lead, Canada
“The rapid growth in satellite launches is transforming how we use space, but it also brings rising risks from orbital congestion and collisions. Protecting future access to near-Earth space will require strong international partnerships, effective regulation, and continuous monitoring to ensure the long-term sustainability of satellite activity.”

The Global Arctic: Unprecedented Transformations, Planetary Stakes
Perspectives from Jackie Dawson (FRSC, University of Ottawa), Topic Lead, Canada
“The Arctic is warming at four times the rate of the global average with widespread and cascading implications for Canada and the world. This important co-developed report recommends fundamentally important ways forward including the urgent need for enhanced national and international cooperation in Arctic science, a renewed commitment to climate change adaptation to reduce risks and limit loss and damage, and to advance innovations in cold-region infrastructure and industrial technologies for self-determined sustainable development pathways.”
Promoting Brain Health (including Mental Health) for Global Societal Resilience
Perspectives from Guy Rouleau (FRSC, McGill University), Topic Lead, Canada
"Brain health is a fundamental human and societal priority requiring urgent, coordinated global action. Approaches grounded in open and collaborative science can accelerate discovery, enable equitable data sharing, and support policy alignment across borders. By integrating prevention and research across the lifespan, G7 leadership can strengthen resilience and reduce global burden."

Centring science in G7 discussions
The three statements were prepared by expert groups from the G7 Academies through an international collaborative process. They were reviewed and approved by each Academy prior to final adoption, presented to President Emmanuel Macron of the French state on the afternoon of Tuesday, May 19, 2026, and are now being forwarded to the government leadership of each G7 country through the Sherpa process.
