Rebecca Hubbard

Rebecca Hubbard is Director of the High Seas Alliance, a global coalition of more than 70 NGOs working to secure protection for the High Seas: the two thirds of our ocean that lie beyond national jurisdiction. She leads a global team and partners across continents, aligning science, civil society and political strategy to accelerate ocean protection at international scale. An environmental campaigner for more than 25 years, Rebecca has worked from grassroots advocacy to multilateral diplomacy. She has participated in over 300 events and negotiations across more than 30 countries, including participating in major global processes such as UNFCCC, CBD and negotiations for the High Seas Treaty (BBNJ). She has played a central leadership role in the “Race for Ratification” campaign that helped secure 60 ratifications of the Treaty in just two years: a milestone achievement for ocean governance recognised internationally, including through the Earthshot Prize. Previously, Rebecca worked with organizations such as Greenpeace and Our Fish, mobilising public and political action to end overfishing and restore ocean health. Over the past decade she has raised more than USD $15 million to advance ambitious ocean campaigns globally. Born on the south-east coast of Australia and raised between forest and ocean, Rebecca holds an Honours degree in Environmental Science from the University of Wollongong and is based on Muwinina country in lutruwita / Tasmania. Her work is driven by a deep belief that the ocean is essential to sustaining life on Earth, and that this decade must deliver decisive protection for generations to come.
