Policy discussions are underway in Japan to promote the social implementation of CCS for achieving carbon neutrality by 2050. In the CCS value chain, CO₂ marine transportation and injection/storage belongs to the shipping and offshore oil and gas exploration in the industrial area, and consequently, the role of shipbuilding, marine construction, and subsea engineering becomes large. First of all, active participation by Japanese companies towards domestic implementation is desirable. And then, considering the topographical features of Japan and Asia, CO₂ hub port system is proposed.

The 30 by 30 target was incorporated in the Kunming-Montreal Global Biodiversity Framework. In order to reach that goal, the Ministry of the Environment is working towards the establishment of Other Effective area-based Conservation Measures (OECM) that meet the requirements for certification. In order to meet the 30 by 30 target in Japanese marine and coastal areas and conserve their marine ecosystems, which are vast and diverse, methods such as marine protected areas (MPA) and OECMs that conform to the unique value and use made of the ecosystems in the ocean areas are necessary. We aim to facilitate effective conservation of biological diversity through initiatives based on cooperation between government and the private sector.

Using high frequency ultrasound to develop equipment capable of noncontact and efficient surveys, demonstrations have been carried out on the deep seabed to map the 3-dimensional distribution of benthic organisms. The heretofore poorly understood distribution of organisms living beneath the seafloor, along with their ecosystems, have now been made clearer, and there are expectations for this new approach as a useful tool to understand the effects of human activity and climate change on benthic organisms as well as the distribution of marine products, etc.
