As the world struggles to decarbonise, it’s becoming increasingly clear we’ll need to both rapidly reduce emissions and actively remove carbon dioxide (CO₂) from the atmosphere. The latest Intergovernmental Panel on Climate Change report considered 230 pathways to keep global warming below 1.5°C. All required CO₂ removal.
Some of the most promising CO₂ removal technologies receiving government funding in the United States, United Kingdom and Australia seek to increase the massive carbon storage potential of the ocean. These include fertilising tiny plants and tweaking ocean chemistry.
