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.

According to data from the Cabinet Office and the Ministry of Education, Culture, Sports, Science and Technology, the ratio of female researchers in Japan is currently quite low compared to the rest of the world. The percentage of women in the ranks of professors, associate professors, and section chiefs or above is extremely low. Based on the above, it is worthwhile to study approaches to derive findings that will contribute to measures to promote the advancement of women in Japan. Therefore, this study obtained data from the Times Higher Education Impact Rankings 2020 and devised a matrix model in which the top 100 universities in terms of 5 Gender Equality achievements were set as the row sample. The 17 SDGs target data were set as the column variables. Then, by applying this matrix model to link prediction, we devised a model to extract a group of universities with high 5 Gender Equality achievements. Then, by analyzing the level of achievement of the 16 SDGs other than 5 Gender Equality in the extracted university groups with the high achievement of 5 Gender Equality, we discussed the findings on the promotion of female researchers in Japanese universities.
