Fujitsu Deploys Digital Twin to Certify Blue Carbon in Coastal Ecosystems

• Fujitsu's system combines drones, AI, and simulation to measure blue carbon faster and without expert personnel.
• Fujitsu validated the technology in the Uwa Sea, earning 95% J-Blue Credit certification for a 1.8-hectare area.

Fujitsu has developed a digital twin system to measure carbon stored in coastal ecosystems, such as seagrass and seaweed. The system is designed to speed up blue carbon credit certification by reducing the need for expert operators. Fujitsu says the system can complete measurements in about 30 minutes per hectare, 1/100th the time previously required. The company intends for the system to be used in seagrass restoration, environmental surveys, and projects that support decarbonization through ecosystem recovery.

The digital twin system combines underwater drones, AI analysis, and simulation models into a single platform. The drones autonomously collect subsea data with high precision, while AI identifies the type and coverage of marine vegetation, even in murky water. Simulation models forecast how seagrass beds may respond to environmental and human-driven changes, allowing conservation plans to be tested in advance.

In a trial covering 1.8 hectares of the Uwa Sea, the system was used to apply for certification under Japan’s J-Blue Credit program and received a 95% accreditation rate. Fujitsu plans to expand its use to marine infrastructure inspections, environmental surveys, and offshore wind sites, and will present the system at Techno-Ocean 2025 in Kobe.

🌀 Tom’s Take:

Fujitsu is turning a complex ecological measurement into a 30-minute, expert-free process with the use of digital twins. It makes routine tracking and restoration of coastal ecosystems practical at scale.
