Basic Approach
The Daicel Group seeks to fulfill its role in realizing a circular society by engaging in Group-wide activities that protect the environment by making effective use of the limited resources in its manufacturing process to minimize the Group’s environmental impact. In accordance with the Daicel Group Basic Policies for Responsible Care, we pursue initiatives under the specific themes of addressing climate change, reducing and recycling waste, reducing emissions of chemical substances, preserving water resources, preventing air pollution, and preserving biodiversity. Daicel’s business sites and Group companies execute their environmental management systems such as ISO 14001 and regularly report their progress while engaging in continuous dialogue with our stakeholders.
Management Structure
The Daicel Group has established an environmental management system under the promotion system for responsible care to implement energy-saving measures, reduce greenhouse gas (GHG) emissions, waste and the environmental impact on air and water quality, and preserve water resources and biodiversity. In each of these initiatives, we strive to protect the environment through continuous improvements by applying a CAPD cycle*through which we revise our plans based on the results of the certification reviews for ISO 14001 and internal audits as well as audits by the Safety and Quality Auditing Office and formulate and execute new plans. We compile the results of our initiatives into the Environmental White Paper annually and report them to executive management and Audit & Supervisory Board members.

Instead of a Plan, Do, Check, and Act (PDCA) cycle, the most widely known approach to continuous improvement, Daicel has adopted a CAPD improvement cycle to avoid the risk of overlooking crucial facts and realities that often lie hidden in the initial planning stage.

Internal Environmental Audits
In accordance with ISO 14001, each business site of the Daicel Group undergoes audits by a certification body and an annual internal audit. The internal audit is focused on auditing compliance with standards, follow-ups on matters that had been previously pointed out, and legal compliance with environmental regulations.
Education and Training on the Environment
The Daicel Group provides education to employees at each business site in accordance with ISO 14001 for operations that have an impact on environmental performance such as our initiatives on climate change, reduction and recycling of waste, management of chemical substance emissions, environmental management of air quality, etc. and with regard to compliance obligations. In particular, we seek to raise awareness of our climate change initiatives among all employees through our internal “Environmental White Paper” and the “Sustainable Portal,” Daicel’s information board.
Status of Compliance with Environmental Regulations
In FY2025/3 and over the last three years, there were no serious violations of environmental regulations at Daicel nor was there any litigation involving fines for violations of the law, punitive measures, or compensation for environmental damages.
