Скачать или смотреть Harnessing Photosynthesis to Remove Gigatons of CO₂

What if the most powerful carbon-removal technology already exists—and it’s called photosynthesis?

In this Davos conversation, Libby Wayman speaks with Ori Shaashua, Founder and CEO of GigaBlue, about a radically different approach to carbon dioxide removal (CDR). Instead of energy-intensive machines, GigaBlue harnesses the ocean’s natural engine—phytoplankton—using a controlled, measurable, and biomimetic system designed to safely sequester carbon in the deep ocean for hundreds to thousands of years.

Ori explains how engineered particles enable carbon fixation and controlled sinking without altering ocean chemistry, how this approach avoids methane and anoxic-zone risks, and why true climate impact requires solutions that are scalable, affordable, and verifiable at the gigaton level. The discussion also explores why CDR is still in its infancy—and why urgency, policy, and collaboration are critical to making it work.

A forward-looking look at carbon removal, ocean health, and how nature-based solutions could reshape climate action at global scale.
