ISBB 2026 Competition Season
International Sustainability Bee & Bowl was founded in response to a rapidly growing global need: to prepare young people to understand, analyze, and address sustainability challenges shaping the future of our planet.
Climate change, biodiversity loss, energy transitions, resource scarcity, and environmental justice are among the defining issues of the 21st century. Solving these complex challenges requires scientific literacy, interdisciplinary knowledge, and systems-level thinking.
By integrating environmental science, biology, chemistry, energy systems, economics, and public policy, the competition offers students a rigorous academic platform to explore sustainability as a unified and dynamic global challenge.
