Integrated Indicator
Sekisui Environment Sustainability Index


What is the Sekisui Environment Sustainability Index?

The SEKISUI Environmental Sustainability Index is a single indicator of the level of impact on the environment by its corporate activities of the Sekisui Chemical Group (i.e. use of natural capital) and the degree of contributions back to the environment (i.e. return of natural capital). This index integrates all of the effects of the key implementation objectives of our medium-term plan: reduce various environmental impact, increase products and services that contribute to the environment, and preserve the natural environment, and others.


Results of calculation

Based on fiscal 2016 performance, the Sekisui Environmental Sustainability Index was calculated as follows. With environmental impact equal to 100 representing the use of natural capital, the return of natural capital as contributions back to the environment came to 76.9. During the three years of the medium-term plan since 2014, there was a 12.4 point increase in the index. Under the new three-year medium-term plan that began in fiscal 2017, the aim is to achieve a 10 point increase, for a 90% return of natural capital.

In order to achieve the targets of our aim for the “Earth with Maintained Biodiversity” by 2030, we aim for a return of more than 100% by implementing initiatives in all our corporate activities.

Calculation Method

After collecting the raw data in (1) above, stages (2) and (3) are calculated using a customized version of the Life-cycle Impact Assessment Method based on Endpoint modeling 2 (LIME2) developed in Japan by Professor Norihiro Itsubo at Tokyo City University. (See p. 34 of this Data Book for calculation basis.)

  • *In fiscal 2016, the contribution from activities to reduce environmental load under return of natural capital was negative (-1.0%), as indicated by missing targets on a production volume unit basis for reducing GHG emissions and reducing waste under initiatives to reduce environmental impact.
