Efforts to Visualize GHG Emissions in International Transportation

The Sumitomo Corporation Group has identified “Mitigation of climate change” as one of its key social issues and has set a long-term goals of creating its business activities carbon neutral by 2050 and a sustainable energy cycle.
To achieve these goals, Sumisho Global Logistics Co., Ltd. (hereinafter “SGL”) set up a working group in 2020 and has been working on calculation and visualization of GHG emissions from international transportation entrusted by the Sumitomo Corporation Group (hereinafter “the work”).

As a result of this initiative, we obtained third-party assurance for SGL’s GHG emissions from KPMG AZSA Sustainability Co., Ltd., which conducted the assurance engagement in accordance with International Standard on Assurance Engagements (ISAE) 3000 and ISAE 3410 of the International Auditing and Assurance Standards Board.
Please refer to "Independent Assurance Report" for further details about assurance engagement.

SGL will expand the scope of these operations beyond the calculation of GHG emissions to proposal and arrangement of transportation methods that lead to the reduction of GHG emissions in the future.
At the same time, to aim creating new value in international logistics, which is the core business of SGL Global Logistics Business Division and further contributing to the reduction of GHG emissions toward carbon neutrality, SGL plans to provide similar functions and services to customers outside the Sumitomo Corporation Group.

＜ Boundary of the Data＞
International ocean and air transportation by Sumitomo Corporation and its major consolidated subsidiaries in Japan, which are arranged by SGL.
・GHG emissions from energy used in SGL offices and warehouses (including those leased) are not included.

＜GHG emissions from International Transportation (Scope 3)＞

Transport Mode	FY 2020	FY 2021
Container vessels	10,275 t-CO2	19,890 t-CO2e
RORO vessels	12,233 t-CO2	16,308 t-CO2e
Bulkers and Tankers	344,146 t-CO2	291,902 t-CO2e
Aircraft	9,673 t-CO2	9,462 t-CO2e

The environmental data marked with “*” assured by KPMG AZSA Sustainability Co., Ltd., an external assurance provider based on International Standard on Assurance Engagements (ISAE) 3000 and ISAE3410.

・From FY2021, GHG emissions are calculated including CH₄ and N₂O in addition to CO₂. Accordingly, the unit in the above table has been changed from CO₂ to CO₂e.

Calculation method

Based on the ton-kilometer method.

Container Vessel

・CalculatedGHG emission by FCL (Full Container Load) only. LCL (Less Than Container Load) is excluded.
・It is calculated using the emission coefficient per distance set for each container type in "2021 Global Ocean Container Greenhouse Gas Emission Intensities" published by Smart Freight Centre (SFC).

RORO vessels, bulkers (including conventional vessels) and tankers

・They are calculated using emission coefficient in "Greenhouse gas reporting: conversion factors 2022"published by the Department for Environment, Food and Rural Affairs (Defra) in the United Kingdom

Aircraft

・It is calculated using emission coefficient published in "Greenhouse gas reporting: conversion factors 2022" published by the Department for Environment, Food and Rural Affairs (Defra) in the United Kingdom.
・Courier and EMS are excluded.
