2025 Summit Closing Keynote – Alexandra Cousteau

Alexandra builds upon more than 60 years of global name recognition to engage people who expect to hear credible environmental information from the third generation of this pioneering family of explorers. 

For millions around the globe, “Cousteau” is synonymous with discovery and protection of our natural world.

Born into this extraordinary legacy, Alexandra embarked on her first expedition to Easter Island at just four months old. By the age of three, she had already toured Egypt, Tunisia, Uganda, and Kenya, exploring the world in the arms of her father, Philippe Cousteau. Following in the footsteps of her legendary grandfather, Jacques-Yves Cousteau, she learned to dive with SCUBA from Captain Cousteau himself at the age of seven, immersing her in a lifelong connection to the ocean.

Alexandra brings this heritage of adventure and discovery into a compelling, modern call to action, inspiring audiences around the world—from policymakers and corporate leaders to students and grassroots communities. With a unique ability to connect with diverse groups, she delivers powerful messages of hope and action, urging us all to join her in the mission to protect and restore our planet’s oceans.
