MOL Conducts Carbon-offset Voyage with Car Carrier
- Offsetting CO2 Emissions from Ocean Transport of Completed Cars for Europe -

June 15, 2022

TOKYO-Mitsui O.S.K. Lines, Ltd. (MOL; President & CEO: Takeshi Hashimoto) today announced that one of the company's car carriers completed a carbon-offset voyage for the ocean transportation of completed cars from Japan to Europe by using voluntary carbon credits (Note 1). This initiative was conducted as a pilot case to study the specific use of carbon credits in ocean shipping to compensate carbon dioxide (CO2) emissions, which are difficult to reduce using currently available technology.

Completed cars from Mazda Motor Corporation (Representative Director, President and CEO: Akira Marumoto; Headquarters: Aki-gun, Hiroshima Prefecture) were loaded on the MOL-operated Beluga Ace, and the vessel departed the Port of Hiroshima on April 18, arrived at the Port of Bristol, the U.K., on May 28.
CO2 emissions during the voyage between Japan and Europe reached about 4,000 tons including all processes from production through consumption of fuel oil. The calculation method of the volume was properly verified by the third-party verification body Bureau Veritas. The entire process, from calculating CO2 emissions including the verification process to compensating all CO2 emissions with carbon credits, was also certified by the third-party certification body Climate Neutral Commodity (Note 2).

MOL used carbon credits generated from afforestation and reforestation projects in Ghana and China (Note 3) for this initiative. Both projects are certified by the international carbon credit standard management body Verra (Note 4), and the credits were generated within the past five years. In addition, these projects contribute not only to absorbing and removing CO2 from the atmosphere (Note 5), but also to several co-benefits such as biodiversity conservation and job creation for local communities.

MOL Group aims to achieve net zero greenhouse gas (GHG) emissions by 2050 in the "MOL Group Environmental Vision 2.1" announced in June 2021. We are committed to achieving net-zero GHG emissions by maximizing emission reduction efforts, such as research and development of zero-emission fuels and replacement of vessels with low-carbon vessels, and also by utilizing carbon credits and creating natural and technology-based negative emissions through co-creation with various stakeholders.

[MOL Group 5 Sustainability Issues]
MOL Group will contribute to realize a sustainable society by promoting responses to the sustainability issues, which are identified as social issues that must be addressed with priority through the business.
We anticipate this initiative to contribute especially to the realization of "Environment -Conservation for Marine and global environment-" and "Human & Community -Contributing to the growth and development of people and communities-".

(Note 1) Voluntary carbon credits
Carbon credits, which are one of methods for putting a price on carbon, exist under two schemes; one is mandatory schemes that are created and regulated by the United Nations or national/regional governments, and the other is voluntary schemes that are led and operated by private sectors. Participants in the latter purchase carbon credits on a voluntary basis with no intended use for compliance purposes, so those credits are called "voluntary carbon credits."

(Note 2) Climate Neutral Commodity
Based in Geneva, Switzerland, it offers services to certify that a series of processes such as calculation of CO2 emissions and retirement of carbon credits conform to international standards such as GHG Protocol and ISO14064, to guarantee transparency in utilization of carbon credits by corporations.

(Note 3) Applied carbon credits

Project name (1) Reforestation of degraded forest reserves (2) Qianbei Afforestation Project
Country/region Ashanti Region, Ghana Zunyi City, Guizhou Province, China
Number of credits 2,082 tCO2e 2,081 tCO2e
Year credits created 2018-2019 2018
Type of credit Carbon absorption/ removal (Note 5) Carbon absorption/ removal (Note 5)
Certification body VCS VCS
Outline Promote sustainable afforestation using teakwood and native species, regenerate natural forests in waterside buffer zones, and prevent illegal logging, with the purpose of reforesting devastated forests. The project contributes to increased biodiversity by reforestation and improve soil and water quality, in addition to creating employment through an intercropping program and reforestation. The project aims to accelerate carbon sequestration and enhance biodiversity in deteriorated lands by planting native tree species with long maturing periods. It creates employment by passing on afforestation/ forest management/ maintenance technology to local communities and aims at recovery of biodiversity through establishment of new forest ecosystems and preventing their decline, and improvement of soil and water conservation.

(Note 4) Verra
Based in Washington D.C., it is an international carbon credit standard management body that manages and certifies the "Verified Carbon Standard (VCS), which is the most widely used in the world.

(Note 5) Types of carbon credits
Carbon credits are categorized into two types in comparison to the assumed baseline of emissions in case of BAU (business as usual); the first is derived from emission reduction and avoidance, in which GHG emissions are decreased as the project is implemented; the second is derived from absorption and removal of carbons, in which the volume of GHG absorbed and removed is increased from the baseline.
