Antonius Gagern

Executive Director, Carbon to Sea

Antonius is the Executive Director of Carbon to Sea, the leading initiative to evaluate whether ocean alkalinity enhancement can safely remove and store billions of tons of CO2. Carbon to Sea spun out of Additional Ventures in 2022, where Antonius directed the ocean carbon dioxide removal program.

Prior to Additional Ventures and Carbon to Sea, Antonius directed the ocean CDR work at CEA Consulting, advising foundations (such as ClimateWorks) on strategy and grantmaking in this field.

Before entering the CDR universe, Antonius was a natural resource economist focused on fisheries and marine conservation in the tropics, as well as on climate smart agriculture. Antonius holds degrees in Biology (BSc.), Marine Ecology (MSc.) and Natural Resource Economics (PhD).
