Fuji Electric's CSR can be described as the implementation of the "Management Philosophy" and "Management Policy", which means that through energy and environmental business, we contribute to the resolution of social issues, maximize the positive impact of our corporate activities on society and the environment as a whole, and prevent or reduce negative impacts.
In addition to in-depth CSR in corporate management, we also hold related CSR activities every year.
In response to the call of the country's "green development", Fuji Electric stepped into East China Normal University, and through the assistance of the Shanghai Putuo District Community Greening Management Institute and the school, Deputy General Manager Takahashi Kiki and his party adopted the "Ancient Tree of Podocarpus" and won the "Certificate of Honor for Adoption".
With the concept of environmental protection, we cooperated with students from the School of Electrical Engineering of Zhejiang University to carry out road environmental protection activities in Hangzhou. We will deeply integrate CSR into the life of society.
In the green belt along the shore of the West Lake, we picked up the confetti of cigarette butts that were not easily noticed by the sanitation workers. Although the weather was cold, everyone still maintained their enthusiasm, and under the beautiful scenery of the West Lake, the labor became more fun. I would also like to thank the students of Zhejiang University for their willingness to take out their precious time to complete this activity together in their busy studies.
We also know that environmental protection does not depend on one day or two to complete. In the future, I hope to implement more similar activities and implement and appeal for environmental protection. Of course, in daily life, we pick up the garbage around us and do not create excess garbage, and recycle as much as possible. By making every day an environmental day, Fuji Electric will always remember its corporate responsibility and contribute to the sustainability of society.
