Due to the necessity for the Group as a whole to tackle environmental conservation activities in order to help achieve a sustainable society, the Company formulated the “Daido Metal Group Environmental Policy”in April 2004.
By promoting business activities based on the concept of “finite resources and finite possibilities for cleansing”, and that take the finite nature of the global environment into account to the maximum extent possible, the DAIDO METAL GROUP as a whole is working proactively towards the formation of a recycling-based society.
The DAIDO METAL GROUP views the global environment as a precious resource for all people to share, and considers protection of the environment to be one of the most important issues facing mankind. We will focus all efforts and technology on preserving the environment.
FY2022 Environmental Activity Target and Result of Activities
We believe that responding to climate change and global warming is a corporate obligation, and regard it as necessary for maintaining and increasing corporate value.As an organization that is expanding its business globally, the DAIDO METAL GROUP works to help resolve the problem of climate change through its business, and to mitigate the environmental impact of its business activities.

* Fuel: Mainly heavy oil, kerosene, light oil, LP gas, and city gas Per-unit: Calculated by CO2 emissions, electricity consumption, and fuel consumption/production value.
We promote energy conservation activities in order to help prevent global warming, and for the effective use of energy resources.
In FY2022 CO2 emissions by the DAIDO METAL GROUP in Japan were 57,933 tons, a reduction of 5.9% from FY2021.
As we continue to make progress with energy effciency at our business sites, we will manage information and promote visualization of the situation in order to cut
greenhouse gas emissions throughout our Group.
▮CO2 emissions by scope
In environmental accounting the costs and benefits of environmental conservation activities are reflected clearly in environmental management and this information is published, so we have been working to understand environmental costs and benefits since FY2001.
We refer to Ministry of the Environment guidelines when aggregating and categorizing the figures, but we have limited our approach to items identifiable as 100% environmental costs.

The amounts of materials, energy and water resources used by the DAIDO METAL GROUP in Japan in FY2022, and the waste generated, are as follows.
Note: Energy usage is presented in accordance with the Energy Saving Act.
■ Business activities and environmental impacts
The Company implements environmental education with the aim of raising the environmental awareness of employees. We work to deepen their basic understanding in relation to environmental problems and the position of the Company, and encourage improvements in day-to-day environmental activities. For employees working at manufacturing sites we explain the relationship between our production activities and the main laws and regulations, and work to ensure compliance with them.
■ Manufacturing Processes and Main Related Laws and Regulations
The industrial waste generated by the plating and machining plants accounts for a large proportion of the Group’s total waste. Since FY2016 the Group has been able to reduce the volume of plating wastewater generated and has also been reusing lubricants and solvents to cut down on the amount
of waste generated. We will continue seeking opportunities to reduce waste and emissions at“Environment Meetings” and implement plans that can make even minor reductions to the amount of waste generated.

■ Trends in generation of industrial waste
All production sites within Japan have acquired certification for ISO 14001, an international standard for environmental management systems. These locations also work to conserve the natural environment by reducing CO2 emissions and cutting the amount of waste generated, amongst other initiatives. We do not limit our efforts to comply with laws and regulations, but also set our own standards, seeking to mitigate and improve risks related to the entire environment in which the DAIDO METAL GROUP operates, including that of employees and customers.
With progress being made in the creation of frameworks for controlling the use of chemical substances at an international level, such as REACH regulations, it is important that management of chemical substances contained in products is implemented appropriately at each stage of procurement, manufacturing, and shipping.
DAIDO METAL’s management of this issue is based on JIS Z 7201 (Management of chemicals in products – Principles and guidelines), and this information is published internally as well as being used to respond promptly to client requests.

Training being conducted at night
In terms of measures to prevent damage to the local environment, the Company considers a variety of risks, and implements annual emergency response training that assumes that an accident could happen at any time of the day or night.
During night-time exercises the safety of workers is of course ensured, and the training is repeated until participants are able to implement the appropriate measures. After training is complete, those involved exchange opinions, and the experience is used to make further improvements.
The Company is rolling out and actively promoting its “Green Procurement Guidelines”, and it has also made the Guidelines available on its website so that all our stakeholders can view the content and related activities.

Saplings being prepared for distribution among employees
As part of its annual greening campaign the Company’s Inuyama Site Office has been setting up green wall panels. Given that this greening campaign doubles as environmental education, we have new employees take part by sowing seeds for saplings. The resulting saplings are distributed to employees in order to widen the circle of greening activities.
