The Japanese government is taking a number of measures to reduce CO2 emissions in order to achieve carbon neutrality by 2050. Many companies are also actively working to achieve this goal. However, it is clear that
it will not be easy to achieve carbon neutrality while maintaining industrial development. In addition to conventional CO2 reduction measures, new approaches, including CO2 fixation, are required. In particular, green carbon has
played a major role in CO2 fixation in the past, but due to the lack of appropriate forest management, the maximum amount of CO2 fixation has passed the age of the trees, and the amount of CO2 fixation is limited. Therefore, there are high expectations for blue carbon in CO2 fixation. The purpose of this study is to design and fabricate pots for seaweed beds and to cultivate seaweed beds in order to realize the formation of environmentally friendly seaweed beds. Assuming the formation of a seaweed bed on the coast of Ishikawa Prefecture, the predictions for decarbonization of blue carbon and its sustainability were verified. We also checked the algae growing there and verified the use of pots for seaweed beds. As a result, the area of the expanded seaweed bed was 5550 ha, and the amount of CO2 fixed by Blue Carbon was 27195 t-CO₂/year, showing great promise for CO2 reduction. The possibility of carbon credits as a trump card for regional development is also discussed.
