Carbon Neutrality

To hand down the beautiful earth to the future is a task shared by the international community and also a major challenge. The TANAKA Precious Metals is pursuing every possibility to minimize the environmental impact of its business activities.

Statement on Carbon Neutrality

The TANAKA Precious Metals will take on the challenge of addressing global warming, a social issue on a global scale, by aiming to achieve carbon neutrality by 2050 and actively introducing technologies that contribute to a decarbonized society within the Group and in society.

To reduce greenhouse gases arising from business activities, we will continuously undertake emission reduction activities, such as increasing energy efficiency, improving manufacturing processes and adopting the use of green energy, at our plants and offices.

At the same time, we will provide products that meet the expectations of customers working toward a decarbonized society, including catalysts that contribute toward greenhouse gas reduction and high-performance materials such as those used in electric vehicles. We will also strengthen our precious metal recycling business to contribute toward a circular economy, thereby creating a prosperous and sustainable future for the Earth with our own hands.
We will consider tree-planting and activities to preserve forest rejuvenation such as the creation of Tanaka Forest.
The TANAKA Precious Metals aims to achieve carbon neutrality through these activities.

In fiscal 2022, we will form a company-wide project team directly controlled by the CEO to consider and implement specific measures. The TANAKA Precious Metals will continue to provide value to customers and society as a whole through products and solutions that apply the unique characteristics of precious metals.
