In Japan, efforts to restore and preserve the marine environment are gaining momentum, with a particular focus on utilizing seaweed and seagrass to capture carbon dioxide. These initiatives aim not only to fight climate change but also to enhance fisheries resources and improve seawater quality. Through a newly introduced system, blue carbon credits are being issued for the CO2 absorbed by oceanic ecosystems, with a framework already established for trading these credits.
One specific example of these conservation efforts involves the Mashike fisheries cooperative association in Hokkaido, which partnered with Nippon Steel Corp. to revive the local konbu kelp population. By burying iron slag in coastal areas to supply iron to the sea, the konbu kelp has seen significant growth, leading to increased biodiversity and economic benefits for the local community. Similar projects have been implemented in over 50 locations throughout Japan, showcasing the success and potential impact of these initiatives.
Recognizing the importance of accurately measuring and evaluating the effects of blue carbon absorption, the Japanese government has proposed techniques to estimate the size of seaweed colonies nationwide and calculate CO2 absorption rates for different types of aquatic plants. This comprehensive approach aims to position Japan as a leader in presenting detailed blue carbon data to the United Nations, significantly contributing to the global understanding and potential criteria for blue carbon initiatives. Japan's efforts in the field of blue carbon footprint are monumental, symbolizing a shift towards recognizing the vital role of marine ecosystems in carbon sequestration and environmental preservation.
