Company's carbon credits raise questions about unproven ocean technology to fight global warming

A startup called Gigablue claims to have reached an important step by selling 200,000 carbon credits for its carbon capture technology in the ocean. The company affirms that its patented particles cultivate algae which traps carbon dioxide, which then sinks into the bottom of the ocean. External scientists, however, question the efficiency and environmental impact of this method, citing a lack of public data and concerns about marine ecosystems. Gigablue has conducted trials in New Zealand and plans to extend operations. While some buyers trust the promises of the company, experts remain skeptical about its unproven technology and the broader implications of these carbon elimination efforts in the ocean.
