As stated in our Environmental Charter, MC recognizes the critical importance of what ecosystems can provide and is committed to protecting ecosystems and any potential impacts on biodiversity. We have identified “Conserving and Effectively Utilizing Natural Capital,” which includes consideration of biodiversity, as one of Materialities that we must actively take on in order to support sustainable growth for MC. Based on these policies and materiality analysis, MC aims to minimize negative impacts on biodiversity from its businesses. For example, we take biodiversity considerations into account when reviewing and making decisions on loan and investment proposals. In addition, we are engaged in corporate philanthropy activities aimed at conserving biodiversity, including the Project in Tropical Forest Regeneration and the Global Coral Reef Conservation Project.

Risk Management

When reviewing and making decisions on loan and investment proposals, MC conducts a comprehensive screening process which considers not only economic aspects, but ESG factors as well. Since 2012, we have employed the Integrated Biodiversity Assessment Tool (IBAT) developed by organizations including the International Union for the Conservation of Nature (IUCN) to help assess potential business impacts by evaluating the status of protected or endangered species in the vicinity of project sites, along with other relevant data on special conservation areas. Besides screening new investment and exit proposals, MC also strives to make improvements to existing business investments by monitoring their management practices.

Working to Safeguard the Natural Environment at the World’s Largest Solar Salt Fields

Exportadora de Sal, S.A. de C.V. (ESSA), a salt manufacturer in which MC and the Mexican Government have equity interests of 49% and 51% respectively, operates the world’s largest solar salt field in northwestern Mexico. ESSA supplies approximately half of the solar salt imported into Japan, and has also established a solid position as a company that supports Japan’s chlor-alkali business, with the salt used as a raw material in PVC and caustic soda. The salt fields are in the vicinity of Guerrero Negro, where a community has grown up around ESSA complete with schools, hospitals, shops, churches and other facilities. There is also a supermarket run by ESSA, and through the various jobs it creates, ESSA is further contributing to the stability of the local community. ESSA has operations within the El Vizcaíno Biosphere Reserve, including facilities located near the Ojo de Liebre lagoon (a UNESCO World Heritage site that is a breeding ground for gray whales). Great care is taken at all times to respect the surrounding ecosystem, while also working to protect and preserve biodiversity. In September 2000, the region in which ESSA is situated was designated by the WHSRN*1, a U.S.-based shorebird protection group, as a site of international importance *2, and in April 2009 the designation was upgraded to that of hemispheric importance*3. ESSA cooperates with the activities of WHSRN such as surveys of bird species in the salt fields and maintenance and protection of nesting sites. In addition, ESSA is working to protect the natural environment through the installations of approximately 200 roosts which protect birds from coyotes and other dangers. ESSA’s salt production activities are leading to the creation of new types of ecosystems. With a similar degree of salinity to the nearby lagoons, the evaporation ponds are home to many species of fish, crustaceans and birds. The 8,000 hectare ponds’ high microorganism density allows them to generate the same amount of oxygen as would the same area of forest in Canada. Under the three environmental policies of “Prevention of Air, Land and Ocean Pollution,” “Conserving the Natural Environment” and “Biodiversity Monitoring,” ESSA will continue to pursue sustainable development in harmony with the environment by engaging in ecosystem research and conservation activities, etc. together with a wide range of stakeholders including members of the local community, local government organizations, universities, and NGOs.

  • *3 At least 500,000 shorebirds annually; OR at least 30% of the biogeographic population for a species

Details of Preservation and Conservation Activities

Key targets for ecosystem monitoring The Baja California Pronghorn , gray whales, wild birds (approx. 140 species), sea turtles ESSA’s environmental conservation team engages in ecosystem monitoring such as population studies (5–12 times per year) and seawater composition tests (24 times per year) in collaboration with PROFEPA (Federal Attorney of Environmental Protection of Mexico) and WHSRN.
Example of activities [1] Establishment of a reserve to protect the endangered The Baja California Pronghorn in cooperation with Mexican environmental protection organization ENDESU and related breeding program (population of approx. 400 individuals within conservation area of about 23,000 ha; two conservation centers created)
Example of activities [2] Periodic audits have been conducted (eight times per year) to estimate gray whale population in Ojo de Liebre and San Ignacio lagoons in collaboration with the National Commission of Natural Protected Areas (CONANP) and the Autonomous University of Baja California Sur (UABCS). These audits have determined the population is now higher than before the year 2000. There remains a medium- to long-term need to determine trends relating to the whale ecosystem and migration patterns.

Forest Conservation Project: Mitsubishi Corporation Thousand Year Forest (Also Known as Yataro’s Forest)

In partnership with the local government, MC is undertaking a forest conservation project in Aki City, Kochi Prefecture, the birthplace of Mitsubishi founder Yataro Iwasaki. The shrinking of the world’s tropical forests has had a major impact on the global environment, including the effect on the conservation of natural ecosystems and the reduction in the absorption of CO₂ which contributes to global warming, extreme whether etc. MC has been engaged in the Tropical Forest Regeneration Experimental Project as part of its corporate philanthropy initiatives since 1990. From 2009, MC has participated in the “Collaborative Forest Conservation Project” in partnership with Kochi Prefecture and Aki City, the East Kochi Forest Association, in line with the forest conservation agreements. The conservation of Yataro’s Forest marks MC’s first major forest conservation project in Japan. Project aims include: conducting activities to preserve and improve forest ecosystem services such as water conservation, allowing MC employees and local people to gain hands-on thinning experience and undertake volunteer activities, and utilizing the forest as a place for environmental education.
