Sustainability - Promotion of Environmental Communication
The Meiden Group engages in dialogue with all our stakeholders to improve reliability in our environmental activities and contribute to achieving a sustainable society. We also proactively disclose transparent information about our environmental policies, initiatives, and results.
The Meiden Group creates ongoing relationships of trust in order to remain a company that is needed by society.
We release unambiguous information concerning our environmental conservation activities and the state of our environmental impact through our website and in reports. We utilize the opinions and needs expressed by our stakeholders to fulfill the Meiden Group’s environmental activities and environmental training.

Meidensha has participated as a partner business in WIPO GREEN since March 2022. The international platform is operated by the World Intellectual Property Organization (WIPO) of the United Nations to promote the use and diffusion of environmental technologies.
We have also registered certain of our environmental technologies and related patents in the WIPO GREEN database. These include an ecotank-type vacuum circuit breaker that does not use greenhouse gases, a ceramic flat-sheet membrane for water treatment devices that contributes to the effective use of water resources, and a charging and discharging device for battery testing that improves accuracy and efficiency in battery research and evaluation.
We will continue to register Meidensha’s environmental technologies and disseminate them widely around the world through WIPO GREEN. This will give more people the opportunity to use them and help achieve a sustainable society by, for example, decarbonizing society and adapting to climate change.
