EnvironmentClimate Change


The Marubeni Group recognizes climate change as a global and highly urgent social issue, and identifies it as one of its Environmental and Social materiality. In our Medium-Term Management Strategy, GC2024, which we released in February 2022, we see “strengthening our green business*1” and “promoting the greening in all our business domains” as core business for our growth. We aim to transform the total environmental impact of its business activities to a positive one by contributing to low-carbon and decarbonization through our business activities while ourselves achieving net-zero GHG emissions.

  • Green business: sustainable businesses which have positive effects on the environment such as decarbonization and the circular economy, and adjacent businesses which supply those businesses with non-substitutable materials, etc.

Disclosure in Line with the Recommendations of the TCFD


Recognizing the importance of climate-related financial disclosures, the Marubeni Group affirmed the recommendations of the TCFD*2 in February 2019.
We are endeavoring to evaluate risks and opportunities engendered by climate change and to enhance related disclosure.

  • The Task Force on Climate-related Financial Disclosures (TCFD) was established by the Financial Stability Board (FSB).

Initiatives for Micro-Scale Hydro-Power Generation Business

The Marubeni Group considers micro-scale hydro-power generation as an important business area, and has been conducting operations in this area through Group company, Mibugawa Electric Power Company since 2006. As this business utilizes natural energy sources, consideration for the environment is essential, and we are also actively working on reduction of waste materials, maintenance of water quality, conservation of energy and resources, and other environmental activities.

“Micro-scale hydro-power generation” is a term used to refer to small-scale hydropower generation operations with output of less than 1,000 kW. These operations do not require the use of dams or other facilities that entail large-scale construction projects, but rather generate power by utilizing streams or agricultural irrigation canals, thus minimizing the development footprint. The environmental impact on water quality and the water habitat is exceptionally low, and there is no impact on land features or scenic beauty. Once up and running, these operations emit almost no CO2, thereby offering benefits in terms of minimal impact on biodiversity and environmental conservation. Since it utilizes local water resources, it has the potential to be an effective technology to realize the production and consumption of local energy, which will be beneficial for the independent development of the region. Moreover, to develop a power plant that coexists with the local community, we are trying to realize the project with the understanding and cooperation of local organization and people concerned through holding events on the theme of environment for residents, inviting lecturers, and deepening understanding of the history of the planned site.

In addition to the Mibugawa Power Station, the Marubeni Group currently operates the following micro-hydro power generation facilities.

  • Producing power locally: Mibugawa Power Company
  • Micro-scale hydro-power station (Hokuto City, Yamanashi Prefecture)

Oshika Power Station No.2 Misasa Town, Tottori Prefecture 4,990kW
Hinogawa Power Station No.1 Hino Town, Tottori Prefecture 4,300kW

Mibugawa Power Station has obtained Eco Action 21*4 certification, the first hydro-power facility to do so. Given that the intake of Power Station No. 2, which is located at the highest elevation, is next to a quasi-national park, and the facilities of the Mibugawa Power Station are in a region with high biodiversity value, we strive not only to avoid destruction of nature, but also to preserve it. As part of that effort, in addition to conducting river cleanup activities and facility maintenance and emergency response training to be prepared for possible oil spills, Mibugawa Power Station takes measures for protection of biodiversity by conducting water quality inspections twice a year, not only to determine whether pollutants are present, but also to check whether the water has the oxygen content required by living organisms. The facility also welcomes local elementary and middle school students and over 100 residents each year for tours of the power station, and presents exhibits of hybrid power generation systems (wind, solar and hydro-power). These and other activities help educate people about renewable energy and pass on the region’s traditional culture.

At the Hokuto City Murayamarokkamuraseki Waterfarm*5, we use existing irrigation canals to supply renewable energy while making appropriate adjustments to the volume of water used to ensure adequate supplies of irrigation water for farmland and water for household use.

At the micro-scale hydro-power station in Shiroishi City, Miyagi Prefecture, the elevation difference in water pipes of water supply facilities is used to generate electricity with minimal impact on the surrounding environment.
In addition, in selling power through Marubeni Power Retail Corporation, we are helping to improve biodiversity by allocating a portion of the electricity fees to forest maintenance and management.
The Marubeni Group aims to develop about 40 micro-scale hydro-power generation facilities in Japan by 2025. Across Japan, we are actively working on generation of renewable energy that contributes to conservation of the local environment and biodiversity.

M&C Tottori Hydroelectric Power Co., Ltd. (hereafter, M&C Tottori Hydroelectric Power) believes that building a trusting relationship through communication with local residents is essential for the safe and secure operation of hydroelectric power generation projects. To this end, M&C Tottori Hydro Power has appointed a “staff member in charge of community coexistence” and has made efforts to reflect residents' opinions of its operations on its website. In addition, the company regularly communicates with local stakeholders, including six local municipalities (Wakasa, Yazu, Kurayoshi, Misasa, Nichinan and Hino Town) and various councils on important issues related to the environmental impacts, e.g. on rivers and a stable water supply, that may arise from construction, inspections, etc. Thanks to these initiatives, M&C Tottori Hydroelectric Power understands each municipality’s needs (including complaints) and business risks and incorporates them into its management strategy.
In addition, M&C Tottori Hydro plans to offer on-site classes and work experience for elementary and junior high schools on the theme of hydroelectric power generation projects. M&C Tottori Hydroelectric Power contributes to the economic development of the region by improving the knowledge of local residents and linking it to the development of the next generation of human resources.

Marubeni Clean Power Corporation (hereafter, “Marubeni Clean Power”) is “committed to solving local social issues and coexisting with local communities and the natural environment.” Therefore, Marubeni Clean Power is developing renewable energies, mainly biomass, with the aim of realizing a “stable energy supply closely linked to the community.” As part of its business activities, Marubeni Clean Power is actively involved in interactions with local stakeholders, such as local environmental fairs and beautification campaigns, conducting power plant tours and distributing solar kits to local elementary school children, and participating in study sessions of the Chamber of Commerce and Industry.
Marubeni Clean Power participates in the “Association of Biomass Power Producers” (hereafter, the Association) as a regular member (Director Company) and serves as its representative director. The Association, which was primarily established by power generation companies, promotes the biomass power generation business and the sound development of the biomass industry, working to help build a sustainable, recycling-oriented society and foster global environmental conservation.

Marubeni Ina Mirai Denki Corporation*6 provides electric power retail and energy-related services in and around Ina City, Nagano Prefecture, with the aim of offering services that address the challenges of daily life in the community. As part of its investment in the community, the company has installed “quick chargers for cars,” which contribute to the local production and consumption of electricity. The company is a member of the Sustainable Environment Subcommittee of the New Industrial Technology Promotion Council under the jurisdiction of Ina City, and it is taking the initiative to work together to build a sustainable environment, including a focus on issues such as climate change and biodiversity.
The Marubeni Group's Mibugawa Power Company also operates a hydroelectric power generation business in the area. As a group, the company will contribute to sustainable regional development by building a business portfolio that helps build a society in harmony with the local community.

Collaborating with Stakeholders

Initiatives for the Sequestration, Capture, and Storage of Carbon Dioxide

Marubeni is an investor in Japan CCS Co., Ltd., which was established in May 2008, in response to the Japanese government’s call for the development of CCS*9 technologies as a countermeasure to global warming. It was founded by major private-sector firms with expertise in CCS-related fields joining forces to meet the new demands. As a private-sector corporation that brings together and integrates CCS technologies, the company conducts surveys on how to commercialize technologies for the separation, capture, transport, and geological storage of CO2, as well as R&D and testing in these fields.

  • CCS is an acronym for Carbon Capture and Storage and refers to the capture and storage of carbon dioxide (CO2). Specifically, it involves technologies for capturing CO2 emitted by factories, power plants and the like before it is released into the atmosphere, transporting it to underground geological strata suited to storing it, and storing it in a stable manner over long periods of time.
Large-Scale CCS Demonstration Project

Marubeni is working on a project to verify the establishment of an international supply chain to liquify hydrogen produced with unused lignite (i.e. “brown coal”) from Victoria, Australia, and transport it to Japan. For the future commercialization of liquified hydrogen made with this technology, it will be necessary to use CCS technologies to capture, and store the CO2 generated in the hydrogen production process. In part because of this, Marubeni regularly visits the Tomakomai CCS Demonstration Project Center, which is a facility in the city of Tomakomai, Hokkaido, operated by Japan CCS Co., Ltd., to observe the work done there. The demonstration project has been running from FY2012 to FY2019, and is slated to store a cumulative total of 300,000 tons of carbon dioxide underground.
