Several high-profile global investors introduced a shareholder resolution to halt Mizuho Financial Group's financing of coal projects. As part of the proposal, Mizuho would be required to disclose climate risks and publish a plan to ensure its investments are aligned with the Paris Agreement. The first of its kinds in Japan, the resolution was supported by major investors, including Institutional Shareholder Services, Glass Lewis, PKA Pension, AP7, Nordea Asset Management (a unit of Nordea Bank Abp), Storebrand ASA, and Kommunal Landspensojonskasse.

The bank responded that the resolution is inappropriate, and investors ultimately rejected the resolution in June 2020.
