Task Force on Climate-related Financial Disclosures(TCFD)

The Toho Gas Group announced endorsement in April 2020 of the Task Force on Climate-related Financial Disclosures (TCFD) to promote analysis of the risks and opportunities that climate change brings to business as well as disclosure of the information this yields. Together with this, we also became a member of the TCFD Consortium, which was established to serve as a forum for discussion by corporations, financial institutions, and other entities endorsing this initiative.
In April 2026, the TCFD Consortium was integrated with certain functions of the GX League to launch the "GX Future Consortium," a collaborative platform where national and local governments, private companies, and other entities work together to promote Green Transformation (GX). Our Group continues to participate in this consortium.

Keidanren Carbon Neutrality Action Plan (formerly Keidanren Plan for Realizing a Low Carbon Society)

The Japan Business Federation (Keidanren) has announced, as its shared vision, the "resolve as members of the Japanese business community to harness our technological prowess and assume an instrumental role in the drive to halve global GHG emissions by the year 2020," and formulated its Commitment to a Low Carbon Society in 2013 (with revisions in 2017). Furthermore, as global interest and expectations for achieving carbon neutrality by 2050 continue to rise, we have positioned this goal as our most important objective and are vigorously promoting it through our newly established "Carbon Neutral Action Plan." Plan.
The Japan Gas Association, which is participating in this commitment, formulated the Carbon Neutral Challenge 2050 and its action plan for the city gas business, which includes targets for 2050.
As a member of the Japan Gas Association, Toho Gas is pressing ahead with a variety of endeavors as measures to reduce emissions of greenhouse gases and reaching targets in the city gas industry.
