When peace speaks the language of science

The main objectives of World Science Day include raising public awareness, building peaceful and sustainable societies, and engaging people in contemporary scientific issues and discussions. Since its establishment in 2002, the day has focused on both promoting international scientific solidarity and applying humanity's scientific and technological achievements for the benefit and well-being of human civilization.

In 2026, the International Science Council (ISC), a non-governmental organization and official partner of UNESCO, invites the public to celebrate World Science Day by exploring science diplomacy and how science can help build bridges across borders, support international dialogue and cooperation, and contribute to addressing global challenges.

The 2026 events are closely linked to the UN-declared International Decade of Sciences for Sustainable Development (2024–2033). The day therefore highlights how scientific cooperation can build trust and foster and strengthen relations between countries, even when they have political or geopolitical differences. Science diplomacy draws on scientific cooperation and evidence-based dialogue to address challenges that transcend national borders. Major challenges facing humanity today, such as climate change, pandemics, water scarcity, cybersecurity and nuclear security, all require both cooperation and an international scientific approach.

The 21st-century challenges require countries to work together through scientific research, knowledge exchange and technological cooperation. In this context, scientific engagement also creates opportunities to build trust between countries experiencing or facing political tensions.

Ultimately, multilevel scientific partnerships help address a range of global problems and challenges that no country can solve on its own.
