Calculation is based on the distance, CO2 intensity for passenger transportation, seat class coefficient, and radiative forcing index. For the intensity of passenger transportation of international flights we used 86.41 [gCO2 / pkm] which we calculated from the "Annual Report of Air Transport Statistics" of the Ministry of Land, Infrastructure, Transport and Tourism
FY 22/Mar:The international flights and domestic transit flights taken by officers and employees of Mitsui's Head Office for overseas business trips and postings are included in the calculation, and passenger emission factors by origin and destination published by the International Civil Aviation Organization (ICAO) are used

Initiatives toward Environmentally-friendly Logistics

Improvement of Land Transport Efficiency We will use more energy efficient transportation methods.
· Using consolidated cargo
· Using larger transport vehicles to increase loading rates
· Reviewing transport routes and methods
Improvement of Sea Transport Efficiency We will continue to provide the following guidance for vessels chartered and/or operated by our affiliated companies.
· Increasing ship loading rates
· Economic cruise speed operation

Assessment of Environmental Liabilities

Currently, corporate management is strongly expected to proactively deal with environmental issues. In addition to complying with legal requirements, we are working to monitor environmental risks of tangible fixed assets through self-driven surveys such as of land and buildings of Mitsui and subsidiaries in Japan, especially for asbestos, PCB, and soil pollution, and make prompt decisions on management policies.

Environment-related fines and penalties

Mitsui did not incur any environment-related fines or penalties in the fiscal year ended March 2022.
