About Planetary
Planetary restores coastal waters’ ability to absorb carbon dioxide through seawater restoration using a process called Ocean Alkalinity Enhancement (OAE). We work in partnership with communities, regulators, industry, and scientists to support marine ecosystems and reduce the impacts of ocean acidification.
Planetary integrates its technology into existing outfall locations, seamlessly removing carbon with common, pre-existing infrastructure.
Since its founding, Planetary is proud to have assembled an incredible team of professionals and partners, united by their connection to the environment and their devotion to investigating safe and meaningful solutions to the climate crisis. They feel a deep sense of purpose in working together with local communities to bring the ocean to the forefront of the toolbox in the fight against climate change.
