Today, at Carbon Unbound West, I had the privilege of discussing Ebb Carbon’s recently announced agreement with Microsoft to remove up to 350,000 tonnes of CO₂ from the atmosphere over the next decade. This partnership is not only the largest marine carbon dioxide removal (mCDR) commitment to date, but also one of the most significant carbon removal agreements across any pathway.
I co-founded Ebb Carbon because I saw the ocean’s unmatched potential to combat climate change at the scale we urgently need. As the world's largest carbon sink, the ocean naturally absorbs gigatonnes of CO₂ each year. However, with excess CO₂ in the atmosphere pushing us toward critical climate tipping points, it’s clear that we need to act quickly and responsibly to remove legacy carbon pollution from our skies.
At Ebb Carbon, we’ve developed an innovative marine carbon dioxide removal solution to do just that. Our electrochemical technology enhances the ocean’s natural ability to capture and store CO₂, while simultaneously addressing coastal acidification. This is a critical innovation, not just for removing excess CO₂ from the atmosphere, but for helping to restore the health of marine ecosystems that are essential to life on Earth.
A Game-Changing Partnership with Microsoft
Securing this landmark agreement with Microsoft is an exciting validation of the mCDR sector, and it’s a big step forward for Ebb Carbon. Working with Microsoft, we are taking an important step toward scaling up marine carbon removal technologies, proving that these solutions are a critical part of the global strategy to reach net-zero emissions.
To ensure that Ebb Carbon’s credit deliveries to Microsoft meet the highest standards of scientific rigor and transparency, Ebb Carbon will measure, report, and verify CO₂ removed with its technology, using Isometric’s recently-announced OAE protocol – the first such protocol published by a carbon registry for this promising removal pathway.
Looking Ahead: Onward and Upward
As we reflect on the significance of this deal with Microsoft, it’s clear that we are standing at the precipice of something truly transformative. The mCDR sector is maturing, and the validation from companies like Microsoft—who are committed to using their purchasing power for meaningful change—will help drive this industry forward.
