Why is “Biodiversity” a critical issue to be addressed?
Explanation of the reason and background

We are engaged in a business that is dependent on natural capital (the gifts of nature) including natural rubber. In addition, many production facilities use large quantities of water for the cooling of equipment, and emit heat and carbon dioxide. We recognize that the burden on the natural environment caused by these kinds of business activities is not unrelated to the loss of biodiversity currently proceeding on a global scale. We view efforts to preserve the links between the variety of life nature has blessed us with (= biodiversity) and to use natural resources in a sustainable manner and carry biodiversity on to future generations to be our responsibility.

Guidelines on Biodiversity

<Basic Policy>

In running our business, we rely heavily on nature’s blessings. We should pass on this rich nature to our future generations by addressing the preservation of biodiversity and utilization of sustainable biological resources through our business activities, whilst recognizing the fact that “linking diversified lives equals biodiversity”, which is the basis of nature’s blessings, has been dwindling rapidly on a global scale in recent years.

<Action Guidelines>

  1. Recognition as a Management Issue
    Since Yokohama Rubber is directly using biological resources and conducting business activities that may affect biodiversity, we recognize the importance and risks towards the grace of nature. Therefore we will address the preservation of biodiversity from a long-term perspective.
  2. Participation by All Employees
    We will raise the awareness of our employees in regard to the grace of nature. All our employees will contribute to the preservation of biodiversity both at work and their local communities.
  3. Determine the Effect on Biodiversity and its Reduction
    We will determine the effect that our business activities may have on biodiversity, and shall thereby try to avoid or minimize such effect.
  4. Preservation of Biodiversity through the Supply Chain
    In order to preserve biodiversity, by understanding that it is important to be considerate as early as the stage of resource extraction, we shall contribute to the preservation of biodiversity at resource mining sites through cooperation with relevant personnel of the supply chain.
  5. Sustainable Usage of Biological Resources
    We will work on any sustainable usage of biological resources by gathering knowledge with regards to biodiversity, and also through technological development, innovation of design and production, or approaches to biodiversity in the value chain.
  6. Information Sharing and Communication
    We will work on the information gathering or social requirement as to preservation of biodiversity; we shall thereby disclose our activities and achievements proactively to facilitate dialogue and tie-ups with our stakeholders, such as customers, local communities, NGOs, and the government.

Vision (attainment goal) / target

In the preservation of biodiversity, we evaluate the impact that our business activities have on the natural environment and upon ecosystems, and then implement conservation activities in order that this impact can be further mitigated. Additionally, we aim for harmony with nature and the development of employees with an awareness of the environment.
YOKOHAMA Forever Forest project achieved its goal to plant 500,000 seedlings in both our domestic and overseas production sites and related department sites in September 2017. Going forward, the project is working toward the new target of planting 1.3 million trees by 2030 through afforestation at production sites and related department sites and the provision of seedlings to communities.

<Overview of Yokohama Rubber’s Activities to Conserve Biological Diversity>

Measures for vision achievement

The locations of our offices differ in terms of geography, history, and culture. Because the living things that live at these locations also differ, we believe that it is necessary to assess the situation and establish issues for each office, and based on this we deploy our biodiversity conservation activities in stages. After gaining a general understanding of the environments surrounding offices, including waters, green areas, nature reserves, residences, and plants, we conduct surveys on the water quality of rivers that our business activities have an effect on, and monitoring of observed wildlife in the communities surrounding offices that have been surveyed, and specify the organisms subject to assessment. Through monitoring throughout the year, we assess the impact of our business activities, determine which organisms are subject to preservation, conduct preservation activities, and release the results.
In water quality surveys, we measure water temperature, electrical conductivity, pH, etc., and in the monitoring of organisms, we conduct bird observation, vegetation surveys, and observation of aquatic organisms and insects.

YOKOHAMA Forever Forest Project

A cumulative total of 561,000 trees have been planted as of the end of 2018. The cumulative total including the number of seedlings provided equates to 940,000 trees. This marks a 72% achievement rate for the target of 1.3 million trees by 2030. In order to assess forest growth and environmental changes, we conduct surveys on the amount of growth (measurement of tree height and diameter at breast height) and surveys on wild birds observed within plant premises. From surveys on the growth amount of seedlings we have calculated the fixed quantity of carbon dioxide from the YOKOHAMA Forever Forest Project and determined that the fixed quantity of carbon dioxide from the YOKOHAMA Forever Forest Project is higher than that for a typical broadleaf forest. This is likely the effect of the mixed planting and close planting of various kinds of trees.
In wild bird surveys at the Hiratsuka Factory, 57 species of wild birds have been observed on plant premises up until now. From the third year of tree planting, we began to see brown-headed thrushes that have a penchant for forests. We believe this reflects how the Forever Forest is functioning as it should as a forest for wild birds. In addition, we observed the crowned willow warbler and the great reed warbler that is seen near water, which suggests that the Forever Forest is functioning as a stopover for wild birds as they move throughout their habitat.

Announcement of procurement policy aimed at maintaining natural rubber as a sustainable resource

Yokohama Rubber announced the Sustainable Natural Rubber Procurement Policy in October 2018 to make natural rubber a sustainable resource. In addition, we participated in the international platform GPSNR (Global Platform for Sustainable Natural Rubber) and started activities.

Communication with communities

At the “10th ThinkEco Hiratsuka” public event held at the Hiratsuka Factory, a panel discussion on biodiversity was held for the fifth year running. Based upon the theme of “What can we do to protect the environment around Hiratsuka waterways? ? Preservation of biodiversity in rivers through regional cooperation,” we gained the participation of a total of around 40 stakeholders including employees, local residents, and environmental NPOs. At the panel discussion, we reported our activities on biodiversity and shared the policies on future activities. In addition, lively discussions were held on the initiatives to formulate a biodiversity action plan in Hiratsuka City that started in fiscal year 2018. All the participants learned about the importance of everyone in the region being interested and cooperating in order to protect the rich nature of Hiratsuka.

Employee education

We are working to preserve biodiversity through our business activities, carrying out employee education to increase awareness, and are further ensuring that all employees act with an awareness of the benefits of biodiversity through employee education. A biodiversity course is now provided for young employees as part of their Technology training, trainees further their understanding through lectures, monitoring, and workshops.

Hiratsuka Factory

The Hiratsuka Factory comprises multiple divisions and departments, thus this has been the location selected for employee training in biodiversity activities in the downstream area of the Kaname River.
The presence of birds including streaked fantail warblers, kingfishers, great reed warblers, bull-headed shrikes, and migratory fish including eels, rhinogobius, and gobies in the Kaname River are indicative that both the river and the nearby sea are healthy. However, investigations of the vegetation showed significant quantities of introduced species such as giant ragweed and bur cucumber, and we decided that our conservation activities should include removal of specific introduced species. Up until last year, our 260 employees have participated in the activities and removed approximately 1.9 tons of introduced species in total.
Monitoring at Kaname River
Removal of foreign plants at Kaname River
In March each year, at the invitation of the Kaname River Basin Watershed Network, we conduct river cleanup activities in collaboration with local government authorities and civic organizations.
Additionally, starting in 2015, we began to rent abandoned land in Yadota, near Komagataki in the Tsuchiya district of Hiratsuka, to create a biotope through manual labor, and activities including the regeneration of the abandoned cedar forest around Yato.
As a result, it has become possible to find Cephalanthera falcata, Cephalanthera erecta, Calanthe discolor and Cymbidium goeringii.

In May 2017, a “dragonfly pond” was made in the grounds of the Hiratsuka Factory through manual labor, and activities began to be held to enable people to experience for themselves our links with other living things by observing the dragonflies, butterflies, frogs etc. that congregate at the pond.
These activities to conserve biological diversity and our ongoing surveys of fixed amounts of CO2 absorption associated with the growth of the Forever Forest planted in and around the site in 2007 were recognized with Association for Business Innovation in Harmony with Nature and Community (ABINC) certification as a plant that is considerate of biodiversity in March 2017.

Mie Plant

Three teams are continuing to implement biodiversity conservation activities as follows.
  • “Black Team”: Conducted water quality survey on rivers that factories discharge wastewater into (Hinokijiri River and Hotosu River) and aquatic life survey on organisms such as killifish
  • “Tall Team”: Measured the number of foreign species removed and native plants and conducted a loggerhead sea turtle egg laying survey at beaches (Ominato sea coast) near to where wastewater flows out
  • “Short Team”: Created biotopes in rainwater ponds at plants, conducted water quality survey, biological survey, aquatic life survey, and water quality measurements
We presented lectures at the local Ominato Elementary School. Children at Ominato Elementary School learned about living things along the Ominato coast, and also participated in removing introduced species. In FY 2018, we newly held tree planting events and outreach classes for five elementary schools in Ise City covering the theme of activities to conserve biodiversity in our biotope. As a general activity, we held clean-up events on five occasions during the year with the community association and local government. In addition, we host a presentation on our activities to conserve biological diversity for the community association and local government twice every year where we exchange views with one another.

Mishima Plant

The factory discharges water into the Goten River, and we had three teams?“Loach Team,” “Softshell Turtle Team,” and “Eel Team”?carry out ongoing surveys into water quality and wildlife.
These confirmed that the Goten River was home to a huge variety of wildlife, including larvae from damselflies and koyama dragonflies; fish such as the Zacco platypus (pale chub) and the dark chub; reptiles including the Chinese pond turtle; and birds such as kingfishers. However, the river also included large amounts of discarded trash, and so after monitoring, we also carried out some cleaning to do what we could in order to preserve the Goten River in a pristine state.
However, river vegetation was wiped out by river dredging at the end of 2016, and the diversity of the river disappeared. Because of this, in May 2019 our Mishima Plant signed a “River Friendship” consent form with the Numazu Civil Engineering Office and Mishima City, and we started working on the regeneration of vegetation in the Goten River and creating an environment conducive to aquatic life.

Shinshiro Plant

We have been carrying out monitoring of water quality in the Noda and Kuroda Rivers, which also receive discharge from factories. In the factory, we restored the biotope which had been at rest. Through these activities, we aim for verification that the discharge water has no adverse effect on the wildlife allowing dragonfly nymphs to live in an environment that the water flows into.
At Yotsuya Senmaida, we are creating and maintaining a biotope in unused farmland. Here, we can find freshwater crabs, pond frogs, forest green tree frogs, fire belly newts, and other creatures.
On October 13, we attended the 4th tree planting ceremony for the “Biodiversity Strategy 2020 of Aichi” organized by the Shinshiro-Shitara Ecology Network Council, and planted 600 broadleaf trees (provided by the Shinshiro Plant) with participants so that the planted trees will provide food for various wildlife on the mountain where conifer trees were thinned.

Onomichi Plant

At the Onomichi Plant, we are carrying out surveys of water quality and of aquatic life, birds, and plants at the Nishifuji Shinsui Park on the Fujii River, as well as observing wild birds and insects within the plant premises.
Surveys of aquatic life in the Fujii River found aquatic insects including mayflies, damselflies, and dragonflies; fish such as cyprinids, sleepers, and rhinogobius; and crustaceans such as mitten crabs and lake prawns.
Within the plant premises, we are providing a mosaic of environments to host wildlife, by growing trees to create a Forever Forest and by creating ponds and marshes from groves, grass areas, and rainwater?this has become home to dragonflies, butterflies, crickets and grasshoppers. Within the plant premises, we can also see nest-building by skylarks, shrikes and redstarts staking out their territories, and wintering by bush warblers.
At the 42nd Fujiigawa Evening held on June 9, we introduced activities contributing towards biodiversity in the plant, and distributed 150 seedlings for the Forever Forest.
Also, we applied for Association for Business Innovation in Harmony with Nature and Community (ABINC) certification in 2017 and obtained it in January 2018.

Nagano Plant

The Nagano Plant is located in an area that is highly natural compared to other plants. As there is almost no drainage other than rainwater, we believe the environmental impact of this plant is low compared to other plants.
Loach catfish, which is a quasi-endangered species in Nagano Prefecture, and stonewort, which is a category I endangered species were found during surveys into aquatic life at the area with our Nagano Plant located that is near the confluence of the Tenryu River and its tributary, the Oshima River, as well as at the Shinsui Park on the Terasawa River.
Based upon the “Forest Adoption Promotion Project” being promoted by Nagano Prefecture, we concluded with Toyooka village a “forest adoption agreement” to cooperate in maintenance of the village’s forest, and are conducting conservation activities.

Ibaraki Plant

At the Ibaraki Plant, we conduct surveys on water quality, vegetation, aquatic life and birds on the Sonobe River where factory wastewater is discharged to. Because the Sonobe River is used as agricultural irrigation water, we take great care in safeguarding the quality of discharge water. Because electrical conductivity is lower and transparency is higher in the water at the plant water discharge area than in other stretches of the Sonobe River, we believe that plant wastewater management is acceptable. A water tank has been installed at the entrance to the plant offices; fish caught in the Sonobe River are able to live in the tank, which contains discharge water from the plant. Appasus, an aquatic insect that is classified as a quasi-endangered species in Ibaraki Prefecture, was found in the aquatic life survey.
When implementing monitoring, the Ambrosia trifida, Goldenrod and Star Cucumber plants that were growing rampantly on the embankments of the Sonobe River were removed; as a result, the area covered by these three non-native species has been reduced.
In 2015, we started surveys of bird life at the plant. Comparing the results of observations within the Sonobe River area has helped us to understand the different environments, further assisting in letting us provide more support for local wildlife.
These activities have been carried out with guidance from the Wild Bird Society of Japan (Ibaraki Office), and from the Omitama Wildlife Association. The activities implemented at the Ibaraki Plant to safeguard biodiversity have been featured on the Omitama Wildlife Association’s website.
In recognition of the above activities, we participated in the poster session of the World Lake Conference (Lake Kasumigaura, Ibaraki, Japan, 2018) held at the Tsukuba International Congress Center in October last year.

Yokohama Tire Retread Co., Ltd. Hokkaido Plant (YTRH)

Located adjacent to Lake Utonai, an internationally famous migratory bird gathering place where the Wild Bird Society of Japan opened the first sanctuary in Japan, YTRH is the only factory in the Yokohama Group that is in this kind of precious environment.
In order to protect this special place, we have been conducting clean-up events from April to November as a conservation activity for Lake Utonai since 2017, and we conduct foreign plant extermination activities in the summer.
During foreign plant extermination in 2018, the number of samples per person reached a record high for Lake Utonai (7770 in total → 555 per person).
In the future, in addition to employees of Yokohama Tire Retread, we will continue meaningful activities together with family members, affiliated companies and the Wild Bird Society of Japan.

Yokohama Tire Manufacturing (Thailand) Co., Ltd. (YTMT)

Yokohama Tire Manufacturing (Thailand) Co., Ltd. (YTMT), a tire plant in Thailand, is located within an industrial park. Because water intake and discharge is centrally managed at industrial parks in Thailand, unlike the plants in Japan, it is not possible to confirm the impact of individual plants on water intake and discharge areas. For this reason, we monitor birds and insects in order to assess the green areas (Forever Forests and biotopes) on plant premises. In order to recreate a rich ecosystem within the plant premises, we are creating two types of biotope?marshes and ponds. We have been carrying out further planting in order to preserve the connection between aquatic and land wildlife. We also secure habitats for local species and conduct environmental education for employees through these activities.
Additionally, we carried out activities to create areas of saline soil, with the aim of helping preserve the wildlife within the Khao Yai National Park, a world heritage site.

Y.T. Rubber Co. Ltd. (YTRC)

Y.T. Rubber Co., Ltd. (YTRC) is located in Surat Thani Province, Thailand and is the only natural rubber processing plant in the Yokohama Rubber Group. While large volumes of water are used in the natural rubber processing process, we work to effectively use water resources through 100% recycling. In April, we introduced a mechanism that reduces water intake by automatically closing the valve when process facilities are not in operation to control the revolutions of the motor. As a result, we reduced water intake by around 30%. By reducing the water we use, we should be able to make greater progress with breaking down effluent in the purification pond through improved separation of impurities in the settling tank. Going forward, we will continue to check the effects of water quality improvement.
We have conducted monthly monitoring of aquatic life (fish) and water quality since November 2014. We discovered that anti-flood ponds are connected to the adjacent Tapi River during flooding in the rainy season, and contain the same kinds of fishes. Additionally, we observed that providing different configurations within the anti-flood ponds allows coexistence of different species of fishes. We found that, currently, 18 different species of fish are living in the anti-flood ponds, and 21 different bird species are found there. We realized that this contributed to saving the different types of fishes in the Tapi river as well as their genomes, and we will continue to monitor water quality trends, so that these more closely match the water quality of the river.

Hangzhou Yokohama Tire Co., Ltd. (CHZY)

Hangzhou Yokohama Tire Co., Ltd (CHZY) is situated in an industrial park in Hangzhou, China. While there are green areas within the industrial park, there are not many species of trees, and the park has a paucity of biodiversity. Accordingly, we have carried out an evaluation of the Forever Forest, and surveys of wildlife within the Forest to confirm whether the Forever Forest at CHZY was suitable for forest dwelling wildlife.
Additionally, the Qiantang River which flows near the plant is connected to many other waterways, and sewage flowing into these has raised concerns about water quality. Together with Hangzhou Normal University and local government, we are implementing biodiversity conservation activities, using one of these waterways as a model for making improvements to water quality.

Yokohama Tire Philippines, Inc. (YTPI)

Yokohama Tire Philippines, Inc. (YTPI) is situated in the Clark Special Economic Zone in Pampanga, Philippines, so it is not near any sizable wooded areas. YTPI contributes to biodiversity conservation by providing habitats for wild birds, insects, butterflies and specific reptiles by planting and growing trees both on and off the factory grounds. We observe the growth of these living things and plants so that their safety and comfort can coexist with that of employees.
In addition, YTPI creates educational materials and holds meetings to raise employee awareness of forest and biodiversity conservation. In order to promote the improvement of the ecosystem in the vicinity, seedlings are provided to the local community, and we hold and participate in tree planting activities outside the factory.
Angeles City, adjacent to YTPI, is considered an “urbanized areas where water use due to intensive consumption is critical” indicated by the Japan International Cooperation Agency (JICA), and the water shortage level is evaluated as “critical” in a report by the environmental NGO Greenpeace.
Angeles City is said to be at risk of having water shortages by 2025. Because of this, at the request of Angeles City’s mayor Edgardo Pamintuan, an activity to plant 1 million trees in Sapang Bato, a water source area, was launched to restore the city's basin. YTPI supports this activity and participates in tree planting activities in this area.

Yokohama Tire Manufacturing Virginia(YTMV)

YTMV is located at the foot of the Appalachian Mountains of Virginia in the eastern United States. The area offers a vibrant natural environment similar to Japan where you can experience four distinct seasons. The growth of the Forever Forest planted at the company’s factory has provided a natural habitat for a large variety of wildlife and wild fowl. The nearby Roanoke River, into which we discharge rainwater, also contains a wide array of aquatic life. We are carrying out activities to balance conservation of this natural environment and our production activities.
In 2015, we began setting up nests to protect the breeding of the Eastern bluebird. All of our employees keep a close watch on the growth of the chicks. We conduct periodic surveys of organisms living at the bottom of the Roanoke River as well.

Suzhou Yokohama Tire Co., Ltd (CSZY)

At Suzhou Yokohama Tire Co., Ltd (CSZY) located in a chemical industry area of Suzhou, China, we launched biodiversity activities jointly with the New District Environmental Protection Council and a Xuguan Town elementary school in December 2016. So far, we have conducted living organism surveys at our plant three times. Biodiversity survey activities can be used not only to understand the status of the bioenvironment at our plant, but also to preserve the local ecosystem while going on plant business activities and promote harmony with local communities.
In past activities, we have observed birds such as sparrows and white eagles, plants including Chinese tallow, Hall crabapple, border privet, dandelions, morning glory and daisies, insects like honey bees and butterflies, and earthworms. Among them, we also pick up tree seeds and raise them as seedlings for Forever Forest activities. The third biodiversity survey activity on December 16, 2018 was conducted jointly by inviting students, family members and teachers from the Jing’en Experimental Primary School. Before starting the activity, participants were told the meaning of the living organism survey, and were then divided into groups to observe living organisms that could be found in the Forever Forest area at our plant. In addition to observing living organisms, this survey activity enabled everyone to know the status of growth of the Forever Forest. It was a good opportunity for deepening understanding of the positive impacts that the growth of our Forever Forest has on the community’s ecosystem.

LLC Yokohama R.P.Z.(YRPZ)

In 2017, we initiated joint research with Voronezh State University of Forestry and Technologies into planting one species of pine tree (Pinus SylvestrysL.) on the premises of our plant. The purpose of this activity is to research how much pine trees will grow in an industrial belt and restore YRPZ’s biodiversity. In addition, this activity has been appraised as a biodiversity research activity. YRPZ and forest science experts from Voronezh State University of Forestry and Technologies are now researching the ideal conditions for the growth of trees. Additionally, we invite children from local schools to help plant oak seeds cultivated by YRPZ.

Up until now, activities have focused on assessing the species that live in areas affected by the business activities of the Yokohama Rubber Group. In the future, we will expand activities to include overseas business locations, and maintain and improve biodiversity in areas where our businesses are located with the aim of realizing sustainable operations.
Because biodiversity is a concept that people in general are still not familiar with, we will enable employees to deepen their understanding of the importance of biodiversity conservation through participation in monitoring activities and conservation activities, and we will actively communicate information to local communities to provide a better understanding of our efforts.
