Mission and History

World Ocean Day catalyzes collective action for a healthy ocean and a stable climate, working in collaboration with youth leaders and a wide range of organizations. World Ocean Day belongs to all groups and individuals, collectively, everywhere. It’s about how we can create a better future with an abundant ocean and a stable climate, by working together.

After three years of mobilizing to protect at least 30% of our lands, waters, and ocean by 2030 (30x30), the collective efforts of the World Ocean Day network and youth leaders, and working with national and global partners, resulted in two major 30x30 victories: adoption of the High Seas Treaty and the Kunming-Montreal Global Biodiversity Framework.
