Continuing to Provide Prominent Value Toward the Realization of a Planet Where Biodiversity Is Preserved

Management Approach

Basic ConceptLessening the Impact of Business Activities on Biodiversity

While the business activities of Sekisui Chemical Group receive blessings of nature coming from biodiversity, they also negatively impact the ecosystem. In April 2008, the Sekisui Chemical Group incorporated biodiversity-related items into its Environmental Management Policy. Following this, the Group has been making efforts to reduce the environmental impact of, for example, greenhouse gas emissions and hazardous chemicals and to prevent pollution by promoting the effective use of resources and energy that are more limited than ever. Having established a set of guidelines on biodiversity in 2011, the Group strives to conserve biodiversity, including the natural environment, through both environmentally conscious business activities and actions to preserve the environment undertaken around the world.

Long-term Environmental Management Vision Toward the Realization of a Planet Where Biodiversity Is Preserved

To contribute to the realization of a planet where biodiversity is preserved, up until fiscal 2019 Sekisui Chemical Group aimed to return more natural capital to the planet than it uses by 2030, through three initiatives: expand and create Environment-contributing Products, reduce environmental impact, and conserve the natural environment.
While engaging in environmental activities with a long-term view to 2050 from 2020, we will maintain our ideal vision of a planet where biodiversity is preserved.
As stated in the SDGs, natural and social environment issues are connected. In order to solve a single issue, we must remain conscious of multiple issues while working to find solutions.
Looking ahead, we intend to strengthen our partnerships with stakeholders and evolve activities conscious of the need to solve not only issues relating to the natural and social environments, but also contribute to realizing a return to social capital as well as natural capital.

Major Initiatives

SEKISUI Environment WeekHeld to Help Develop Human Resources with Excellent Environmental Activity Promotional Skills

At the Seventh SEKISUI Environment Week, held in fiscal 2019, a total of 27,868 employees participated in activities.
The activities were creatively devised to match each business site and included beautification around the areas, tree planting, energy-conservation in the offices and much more.

Procurement of Sustainable Raw MaterialsUsage of Sustainable Timber and Assurance of Traceability

To contribute to the elimination of deforestation as well as the sustainable use of timber resources, at Sekisui Chemical Group every effort is made to ensure that the timber used in products is logged in accordance with statutory and regulatory requirements, such as FSC-certified wood. In addition, the Group conducts investigations into commercial distribution with regard to the logging area, tree species and quantity of timber materials to ensure traceability. For recycled materials, we use timber- and wood-based materials that are already used in markets, as well as unused thinnings and branches.

Initiatives to Improve Green Space QualityInitiatives to Improve Green Space Quality at All Domestic Production Sites and Laboratories

We are moving forward with efforts to improve green space quality at business sites with the aim of maintaining flora and fauna habitats, building ecosystem networks that connect regions and business sites and invigorate regional partnerships. Under the Environmental Medium-term Plan (2017-2019), we aimed to improve our score on the JBIB Land Use Score Card® by five points compared with fiscal 2016. Under the guidance of the environmental consulting company Regional Environmental Planning, Inc., in fiscal 2019 we improved our average score 5.3 points compared with fiscal 2016 as a result of planting native shrub species in green spaces and of ceasing the use of herbicide (chemical agent) sprays. Under the New Environmental Medium-term Plan (2020-2022), we aim to improve our score by three points compared with fiscal 2019.

Corporate Alliance-based Biodiversity Conservation Activity Case StudiesBiodiversity Biwako Network “100 Dragonflies Initiative – Save Shiga’s Dragonflies!”

As home to Lake Biwa, Shiga Prefecture is a hot spot of biodiversity in which roughly 100 species of dragonflies, half the number of species confirmed in Japan, have been found. Together with seven companies that operate business sites in Shiga Prefecture, Sekisui Chemical Co., Ltd. Taga Plant and Sekisui Taga Kako Co., Ltd. participate in the Biodiversity Biwako Network (BBN), a project that goes beyond the framework of corporations to promote biodiversity conservation in Shiga, and conduct firefly conservation activities.
The BBN periodically studies firefly habitats and has currently confirmed 75 species. Under the counsel of experts, the awareness gained through these studies is deployed in protecting habitats within the plant grounds, as well as in creating and maintaining habitats. These actions have seen a certain degree of success in protecting the rapidly declining habitats of the scarlet dwarf dragonfly (Nannophya pygmaea). The Taga Plant conducts biological studies in the area around the town of Taga twice a year, and is currently partnering with the Taga Town Museum to confirm the biodiversity of the region. Moreover, the Taga Plant has installed container biotopes that attract dragonflies to the plant grounds, thereby creating an environment in which dragonfly nymphs can be bred. The Taga Plant also actively holds and participates in events, including natural environment field trips. An exhibit at the Lake Biwa Museum has attracted roughly 26,500 visitors and has served as an opportunity to raise interest in biodiversity among local residents.
These BBN activities have also been recognized by society and received the Judges’ Award during the 2019 Biodiversity Action Award Japan, organized by the Japan Committee for the United Nations Decade on Biodiversity. The Taga Plant also acquired the highest three-star rating under the Shiga Biodiversity Action Certification Program. Although the deterioration of dragonfly habitats is currently progressing, through dragonflies the Taga Plant intends to continue contributing to the conservation of biodiversity and towards the realization of a sustainable society.

Promoting Biodiversity in the Housing BusinessTown Development That Takes Natural Environments and Ecosystem Preservation into Consideration

The Sekisui Heim Group is working to create sustainable town schemes by maintaining and improving the property value of the towns in its residential housing business.
In Smart Heim City Asaka, the lots of which Tokyo Sekisui Heim Co., Ltd. commenced selling in the spring of 2019, approximately 25% of the development area was set aside as green space,*1 and town development was carried out in consideration of the surrounding natural environment and ecosystem preservation. We established a park with an open grassed space in "Neighbors Circle*2", which will become a town landmark, and the road leading from there to the area where the lots are being sold is being developed as a lush, dedicated road for pedestrians and cyclists. In addition, "Fitness Park", which consists of a park with fitness equipment and a promenade along the Kurome River, is a healthcare area zone where people can exercise while communing with Nature. As a result of its greening policy with a sense of unity and continuity, Smart Heim City Asaka acquired Ikimono Symbiotic Coexistence Enterprise Certification, awarded by ABINC*3, in fiscal 2018.

Environmental Contribution Activities in Collaboration with Local CommunitiesExpanding Initiatives at Domestic Production Sites and Housing Companies

Sekisui Chemical Group is promoting measures aimed at protecting the natural environment in collaboration with local communities at domestic products sites and laboratories. Working in partnership with NPOs, elementary schools, and local government authorities, we pushed forward various initiatives in such areas as woodland conservation and environmental education at 27 business sites in fiscal 2019. This was an implementation rate of 57.4%.
At seven* of its mainstay housing companies, Sekisui Chemical Group has also been engaging in forest and woodland conservation activities since fiscal 2013. In addition to gaining an insight into the importance of the multifaceted functions of forests, steps are being taken to improve communication with local communities through increased collaboration. All seven housing companies implemented activities in fiscal 2019.

Wastewater WETInvestigation of Causes at Business Sites Where Impact Had Been Confirmed by Previous Surveys

Sekisui Chemical Group strictly adheres to wastewater standards regulated by laws and ordinances and has set even tougher standards for the management of wastewater from its production sites. To prevent negative effects on and ensure the safety of the water environment for aquatic life in the places where wastewater flows, the Group has conducted whole effluent toxicity (WET) assessments of wastewater and surveys of the habitat conditions in the rivers where wastewater is released since fiscal 2013.
Looking at past surveys, 96% of the water emitted into public water areas by Sekisui Chemical Group production sites has been checked. Although the Company has continued to conduct investigations into methods of reducing emissions of causative agents at business sites where past surveys have revealed an impact on living organisms, in fiscal 2019 we also succeeded in reducing these causative agents by changing the production lineup. We continuously monitor whether we satisfy the wastewater standards regulated by the Water Pollution Control Law and ordinances.
