Numerous future tasks have been identified (Table 12.7). For example, in the
creation of credits, the accuracy of calculation should be improved and monitoring
should be implemented; in the credit transactions, the application format should be
simplified and a donation system should be designed; and in the promotion of the
project, the dissemination of information should be strengthened and a co-benefit
evaluation method should be constructed. The tasks were identified by examining
the successes and failures of the first trial of the social experiment, which is an
important step for improving the project in the future.

Storage Rate
The high potential capacity for blue carbon production by the seagrass Zostera
marina is clear from Chaps. 1 and 2 (Hori et al. 2018; Miyajima and Hamaguchi
2018). In 2014, however, Yokohama City issued offset credits targeting only blue
