Support for the Task Force on Climate-Related Financial Disclosures (TCFD)

UDAM expressed its support for the Task Force on Climate-Related Financial Disclosures (TCFD) in April 2022 in order to promote the disclosure of information related to climate-related issues.
At the same time as this support, we also joined the TCFD Consortium.

In the consortium, which includes many TCFD-supporting companies and organizations within Japan, discussions are being held on how to disclose information related to climate issues and how to utilize it.
Through the consortium, we are making a wide range of proposals to society on issues such as approaches to climate-related issues, disclosure of related information, and how to utilize that information.
