The Japan Climate Initiative (JCI) is pleased to announce that Mr. Sergio Shigeo Kato (former Senior Corporate Officer, Ricoh Company, Ltd.) joined JCI as Co-Representative.

As Ricoh’s executive in charge of sustainability, Mr. Kato led the company to become the first Japanese company to join RE100 in April 2018. In addtion, as Co-Chair of the Japan Climate Leaders Partnership (JCLP) and a board member of the World Environment Center and Global Compact Network Japan (GCNJ), he has led the corporate and industrial sector’s contribution to solving social issues, particularly climate change issues. Together with Takejiro Sueyoshi, he also advocated for the creation of a broad network of non-state actors in Japan and contributed to the establishment of JCI in July 2018.

JCI looks forward to working with the whole soceity to further develop the efforts of Japan’s non-state actors in the wake of his appointment as Co-Representative.



“In 2015, I participated in COP21, where the Paris Agreement was adopted, and witnessed the strong commitments to zero emissions among the world’s business leaders. This led me to work on Ricoh’s commitment to decarbonization, becoming the first Japanese company to participate in RE100, coaxing our business and the SDGs, and transforming to ESG management as the executive in charge of sustainability. Later, as co-chair of the Japan Climate Leaders’ Partnership (JCLP), I have worked to contribute to solving social issues in business and industry. I proposed the establishment of the Japan Climate Initiative (JCI) as a broader framework that includes not only corporations, but also local governments, universities, research institutions, and NGOs, in order for all non-state actors to work together toward the realization of a decarbonized society in Japan. As a tag-team with Mr. Takejiro Sueyoshi, I will do my utmost to ensure that the JCI will be an even greater force for progress in climate action.”
