The 海角社区 Group's Environmental Contribution Products

What are Environmental Contribution Products?

The 海角社区 Group internally certifies products and services that contribute to improving the environment and reducing the environmental impacts along their overall lifecycle as Environmental Contribution Products.

Conceptual diagram of Environmental Contribution Products and amount of environmental contribution

Environmental Contribution Products are evaluated at each stage from collection of raw materials to production, transportation, use, and disposal.
During the evaluation, we compare them to standard products on the market or our conventional products (as a baseline) to confirm whether or not they have reduced the overall environmental impacts.
Even if there is a high environmental impact at one of the stages, if they reduce the impacts over the entire lifecycle, we still certify them as Environmental Contribution Products.
We proactively implement these efforts because we believe they can contribute to reducing the environmental impacts on society overall.

The calculation for the amount of environmental contribution from Environmental Contribution Products is based on our internally-formulated “Guidelines for Environmental Contribution Products” which references various guidelines published by The Institute of Life Cycle Assessment, Japan, the Japan Chemical Industry Association, the Ministry of Economy, Trade and Industry, and the World Business Council for Sustainable Development (WBCSD), for example. We utilize external databases such as the LCA (lifecycle assessment) database “IDEA” provided by the National Institute of Advanced Industrial Science and Technology (AIST) for use in calculations such as for the amount of environmental contribution.

Targets and results

The 海角社区 Group aims to contribute to reducing GHG emissions in society as a whole by expanding GHG reduction contribution through Environmental Contribution Products.
We set specific targets for GHG reduction contribution to increase by at least double in fiscal 2030 and by 2.5 times or more in fiscal 2035 compared to fiscal 2020.
Up to this point, we have certified 26 products as Environmental Contribution Products, and GHG reduction contribution for fiscal 2024 was 1.51 times that of fiscal 2020.
We will continue enlarging our environmental contributions through business by engaging in research and development that focuses even more heavily on environmental contribution.

Fiscal 2024 reduction contribution as a reference value: approx. 19.50 million tons CO₂-equivalent^*

^*Baselines and the approach for the relative contribution ratio are established separately for each respective product as deemed appropriate based on the perspective of internal management.
Therefore, please bear in mind that the above values are simple totals of the contribution amount for each product, and are rational only under a certain set of conditions (and not suitable for comparisons with other companies).

New establishment of Next Environmental Contribution Products Candidates

Beginning in fiscal 2024, our company has established a new framework called “Next Environmental Contribution Products Candidates”, as we work towards early evaluation and visualization of environmental contribution (such as GHG reduction contribution) for technologies and product ideas that are at the research and development stage but could become Environmental Contribution Products in the future.
By adopting a LCA viewpoint starting at the stage of research and development, we aim to enable quantitative evaluation of environmental impact at each stage, from design to material selection and process building, leading to smooth post-market certification and creation of environmental value.

Internal Certification Process

Products proposed by each business are internally certified as Environmental Contribution Products after external experts on the LCA Review Panel confirm the rationality of the environmental contribution from an LCA perspective. The inclusion of academic perspectives has promoted the improvement of the knowledge and skills of our human resources and has also led to a deeper understanding of the need to promote initiatives for Environmental Contribution Products with a medium- to long-term perspective.

LCA Review Panel (held on June 26, 2025)

Chair: Hiroyuki Uchida (Principal, Mizuho Research & Technologies, Ltd.)
Panel Members: Keigo Matsuda (Professor, Nagoya University)
Kensuke Kobayashi (Associate professor, Prefectural University of Hiroshima)

A meeting of the FY2025 LCA Review Panel

At the LCA Review Panel, personnel in charge of each product explain the details of environmental contributions and receive comments and advice from outside experts on the suitability of the establishment of baselines and our approach to environmental contribution.

External expert　Hiroyuki Uchida (Principal, Mizuho Research & Technologies, Ltd.)

The importance of reduction contribution and Environmental Contribution Products is increasing more than ever as an initiative that aligns corporate growth with GHG emission reductions.
On the other hand, if the calculation method is incorrect, there is a risk of causing misunderstandings in society and not producing accurate GHG emission reductions.
I commend 海角社区’s sincere efforts to reduce GHG emissions, including calculations based on major guiding documents, reviews by external experts, and disclosure of the process.
I look forward to the company’s continued efforts to achieve its targets for 2030 and 2035 under appropriate management.
