Conserving the Natural Environment

We Strive to Conserve Natural Environments and Biodiversity.

Management Approach

Basic ConceptLessening the Impact of Business Activities on Biodiversity

In April 2008, the Sekisui Chemical Group incorporated items relating to biodiversity into its Environmental Management Policy. In 2011, the Group established a set of guidelines. The Sekisui Chemical Group has striven to conserve the natural environment, including in terms of biodiversity, through both environmentally conscious business activities and actions to preserve the environment undertaken around the world.

Biodiversity AssessmentAssessing the Environmental Impact and Confirming the Effect on Biodiversity

At the Sekisui Chemical Group, the Environmental Subcommittee of the Group, which is positioned under the CSR Committee, headed by the President, meets twice a year to deliberate on biodiversity with regard to the Group’s business activities, and to assess their impact. As a specific method to assess impact on the environment, the Company uses the JBIB Land Use Score Card®*1, a tool for evaluating the level of effort to preserve biodiversity with respect to land use, as well as WET*2, which evaluates the impact on living organisms exerted by waste water.

With the Sekisui Chemical’s large-scale land developments including the construction of one of its plants, or when new land is acquired as a result of an M&A or other activity, the Company conducts an environmental impact assessment with regard to the potential effect that the Company’s business could have, including on the air, bodies of water, or soil. Within this environmental impact assessment, we also confirm the impact on biodiversity.

Major Initiatives

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

For a fifth time, in fiscal 2017, a total of 25,277 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.

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 5 points compared with fiscal 2016. As a result of planting local seeds and saplings, activities to get rid of invasive alien plants, and other activities, we had improved our average score by 2.6 points (compared with fiscal 2016) in fiscal 2017.

An Example of Our Initiatives to Improve Green Space QualityCreating Heim Forest, a Biotope with Its Roots Deep in the Local Area

In May, 2017, Kyushu Sekisui Heim Industry Co., Ltd. finished construction of a biotope (named "Heim Forest") the Company had been operating on its business site.
The company planted 27 kinds of seeds and sapling native to Tosu, the area the Company is located in, such as Camellia japonica and Cornus kousa, which all grow very well in the region, and created a biodiversity-sensitive, green tract of land inviting all kinds of living things of the surrounding area to live there. During the SEKISUI Environment Week held in fiscal 2017, as a part of the initiative, company employees attached tree name tags to trees in the area. Heim Forest is used by employees on weekdays as a space for relaxation and also by visitors to the factory during factory tours as a resting area. In the future, the Company intends to improve the quality of this green space further and perhaps even make it open to residents of Tosu and other neighboring areas.

WET Evaluation of WastewaterInvestigation of Causes at Business Sites Where Impact Had Been Confirmed by Previous Surveys

The Sekisui Chemical Group strictly follows 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 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 the Sekisui Chemical Group production sites has been checked. In fiscal 2017, the Company conducted investigations into causes at business sites where past surveys have revealed an impact on living organisms.

Performance Data

Results from the JBIB Land Use Score Card®

JBIB Land Use Score Card® Increase by 2.6 points
Index Calculation method
Points of JBIB Land Use Score Card® JBIB Land Use Score Card® is a tool promoted by JBIB, which evaluates the level of effort to preserve biodiversity with respect to the land owned by the Company. It is a sheet for evaluation of every business site regarding the size and quality of its green space, management system, etc. on a scale from 0 to 100.
We implement assessments of every business site for the fiscal year using the JBIB Land Use Score Card® and calculate the increase from the number of points it had in fiscal 2016. The index is the average value of the points increase of all business sites.
