Conserving the Environment

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, 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 VisionToward the Realization of a Planet Where Biodiversity Is Preserved

To contribute to the realization of a planet where biodiversity is preserved, SEKISUI CHEMICAL Group engages in activities based on the “Sekisui Environment Sustainability Vision 2050*1.”

As stated in the SDGs, natural and social environment issues are interconnected, and thus 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*2.

Biodiversity Assessments

At the twice-yearly meetings of SEKISUI CHEMICAL Group’s Environmental Committee, which has been established under the Sustainability Committee chaired by the president, biodiversity relating to SEKISUI CHEMICAL Group’s business activities and assessments of the impact those activities are having on biodiversity are deliberated.

Furthermore, when new land is acquired, for example through large-scale land development, such as when constructing our own factories, or through M&A, we carry out environmental assessments of the impact that our business may have on the atmosphere, water areas, soil, etc. During these environmental impact assessments, we also conduct verification of any impact with regard to biodiversity.

Major Initiatives

Usage 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.

Previously, traceability surveys were limited to timber and wood-based materials used in manufacturing at domestic production sites, but from fiscal 2020, we are conducting surveys globally, including at overseas business sites.

Initiatives 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 (2020-2023), we aimed to improve our score on the JBIB Land Use Score Card® by three points compared with fiscal 2019. Under the guidance of the environmental consulting company Regional Environmental Planning, Inc., in fiscal 2020 we improved our average score 1.3 points compared with fiscal 2019 as a result of identifying non-native organisms requiring attention, creating a manual and exterminating them and improved our score by 1.3 points compared with fiscal 2019.

Activities to Eradicate Non-native Species (Plants)

Many non-native species have already invaded and become firmly established all around us. Some of them are plants that damage ecosystems and others are plants that are harmful to people. In contrast, there are also rare plants that are declining in numbers due, for example, to environmental degradation.

Based on this situation, SEKISUI CHEMICAL Group has been conducting surveys of exotic plants and precious plants in and around its business sites with the cooperation of experts at 15 factories and offices since FY2018. After selecting those non-native species (plants) to be eradicated from the viewpoint of high invasiveness and harm to humans, we prepared a countermeasure manual that describes appropriate removal methods and timings and are using it to conduct on-site confirmation. We are also continuing to carry out eradication-related activities, such as receiving lectures on eradication from experts on an as-needed basis.

To create and maintain better environments within our business sites, it is desirable to focus on non-native species and species conservation (precious species) while managing green spaces that show that we give consideration to biodiversity.

Promoting Biodiversity in the Housing Business

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 fiscal 2020, the SEKISUI Safe & Sound Project*1 for the complex large-scale "Asaka Lead Town" was certified as an ABINC ADVANCE certified facility*2, the first time by a single corporate group. Tokyo Sekisui Heim Co., Ltd.'s "Smart Heim City Asaka" had acquired ABINC certification (FY2018) for town and community development. As an initiative for sustainable town and community development, from the perspective of biodiversity, we have achieved a high ratio of green coverage at "Asaka Lead Town" by planting an abundance of plants centered on the native species of the region throughout the town. We are also trying to mitigate damage from torrential rain having adopted disaster-resistant infrastructure equipment and utilizing the water retention capacity of the green spaces. In addition, we are planning to hold a variety of events to revitalize the local community through the green spaces. These events could include, for example, nature meetings to observe creatures and study plants in which several generations can take part, tree planting by residents for the purpose of increasing the number of trees and plants that attract wildlife, the production and installation of bird nesting boxes that attract native birds that are unique to the region, and riverbank clean-up activities. The plan is for subsidiary companies to take the initiative in conducting a range of events.
