Corporate Social Responsibility (CSR) Code of Conduct：
Corporate Social Responsibility (CSR) Code of Conduct.pdf
The Sustainable Development Goals (SDGs) were agreed upon and adopted by 193 countries at the UN General Assembly in September 2015. SDGs consist of 17 goals and 169 targets to be achieved by 2030.
Under our Sustainability Policy, we will promote our business in “water” and “energy” fields, contributing to the achievement of the SDGs. We have been, and will continue to be, a company that contributes to society.
Based on our Sustainability Policy, we commit to our CSR Code of Conduct, contributing to achieving the SDGs through environmentally conscious business activities within our core domains of “water” and “energy.” We focus on six SDGs as follows.
Among these, the SDGs we address as core goals are “6. Clean Water and Sanitation” and “7. Affordable and Clean Energy.” We will contribute to the SDGs related to our business domains of “water” and “energy,” realizing a sustainable society through our business activities in Japan and overseas.
Ensure availability and sustainable management of water and sanitation for all.
“Water-Related Business”: Groundwater, when properly managed and conserved, is recognized as a stable and sustainable water source. Our “Water Intake Screens” are used for efficient groundwater intake. For water treatment, we support a circular economy through the promotion of our “Chemiles” water treatment system. Chemiles minimizes waste using chemical-free water treatment technology with extremely low environmental impact.
Ensure access to affordable, reliable, sustainable and modern energy for all.
“Energy-Related Business”: We continue to supply products called “Screen Internal“, which are used in the production process of chemical raw materials (propylene) processed from “propane gas,” a clean energy source, instead of crude oil. Recently, our other products have delivered to waste oil refining plants for Sustainable Aviation Fuel (SAF) production. Furthermore, we will contribute through modernization projects to upgrade existing petroleum refining and chemical plants with more energy-efficient equipment.
Furthermore, we will contribute to a sustainable society through our support with partner companies and our value chain network regarding the following SDGs.
Based on our Sustainability Policy, we aim to fulfill our social responsibilities as a company, respect the principles of the United Nation Global Compact, promote initiatives toward achieving the SDGs, and pursue sustainable material procurement.
We require our major suppliers involved in our supply chain to establish a Corporate Code of Conduct and management system similar to ours, based on our CSR Procurement Guidelines, and request self-assessments regarding CSR procurement.
The Corporate Code of Conduct covers: Information Security (Protection of Personal and Confidential Information), Business Continuity Planning (BCP Development), etc.
In terms of management systems, we will promote the establishment of management systems on the part of our business partners, supplier management, import/export management, the development of complaint handling mechanisms and the monitoring of progress.
Through these actions above, we aim to realize our sustainable supply chain management.
