Gigablue is a company that helps fight climate change by removing carbon dioxide (CO₂) from the atmosphere using the ocean. They create special nutrient particles that encourage tiny ocean plants called phytoplankton to grow. These plants absorb CO₂, and when they die, the particles sink to the deep ocean, trapping the carbon for thousands of years. Gigablue uses advanced technology and artificial intelligence to find the best places in the ocean for this process. Their goal is to remove a massive amount of CO₂—up to one billion tons—by 2035, helping businesses and governments reach their climate goals.
