About Planetary
Planetary removes carbon dioxide from the atmosphere safely, durably, efficiently, and at scale. We’ve already delivered hundreds of independently verified tonnes of removal to pioneering clients including Stripe, Shopify, and British Airways—demonstrating both trust and market demand.
How does Planetary do this? Through a process called Ocean Alkalinity Enhancement (OAE), we restore coastal waters’ natural ability to absorb carbon dioxide. In doing so, Planetary not only removes carbon but also supports marine ecosystems and reduces the local impacts of ocean acidification. Our work is advanced in close partnership with communities, regulators, industry, and scientists to ensure safe, transparent, and scalable climate impact.
Where does Planetary do this? By integrating directly into existing outfall locations, our technology seamlessly removes carbon using common, pre-existing infrastructure such as steel mills, wastewater treatment facilities, and power plants. Planetary’s operational system fits within two shipping containers and can be deployed in days. This modular, infrastructure-ready approach makes our system uniquely simple to scale globally.
