Several reports describe new U.S. regulatory progress for ocean-based carbon removal alongside ongoing controversy and funding challenges. The Conversation reports that an approach involving deep-ocean processes has received a rare approval from the Environmental Protection Agency (EPA). The approval comes as ocean carbon removal efforts continue to expand, but public and scientific scrutiny remains significant. Phys.org frames the development in the context of broader difficulties faced by companies and researchers working on methods to remove carbon dioxide from the atmosphere. The two outlets also note that momentum in the field is affected by changes in major funding. The Conversation specifically says Microsoft withdraws as a major funder of carbon removal projects, highlighting a potential shift in private-sector support even as some technologies gain regulatory clearance.
Taken together, the sources indicate that at least one deep-ocean carbon removal concept moves forward under EPA review, but the sector continues to face uncertainty about effectiveness, environmental risks, and sustained investment. The reports focus on the approval and the wider challenges affecting carbon removal innovation, rather than concluding that deep-ocean sinking plants is definitively the solution to climate change.
