Mizuho Financial Group has many targets they are aiming for in regards to sustainability. The progress they have made on targets is just beginning to show results. The company is fairly new and most of the plans they have are in the process of being implemented, not all of them have come to fruition yet.

The most notable of these is how much they have reduced their CO2 emissions. Their goal by 2020 was to be reduced 19% as of 2030 compared to 2009 and they have already reduced by 25.9%. In regards to the SDGs, they comply with twelve of the seventeen goals, which is substantial. The issue is most of their sustainability goals overlap making it difficult to determine if they truly comply to them or not. They also do not have any certifications shown. 

Mizuho is making larger strides to attain sustainability. Their efforts of installing ‘Green Branches’ which run on solar power and LED lighting show an effort to reduce their CO2 contributions. They promote programs within the company between employees to be more environmentally conscious.

Despite its sustainability initiatives, Mizuho Financial Group has invested $123.472 B in the fossil fuel industry since 2016. Although its investments dreacreased by approximately $8B since 2019, Mizuho is still considered one of the top 10 contributors to the fossil fuel industry. These actions cannot be ignored.

Mizuho has been rated a C.

Analyst Outlook: Negative

Mizuho is mapping the way for sustainability for financial institutions. They have plans to implement sustainable practices and are already surpassing current goals.

However, its involvement in the fossil fuel industry cannot be ignored. The bank would receive a higher rating if it continues to decrease its investments in the fossil fuel industry.

Key Points

  • 2020 report doesn’t include the last fiscal quarter of 2020.
  • Fairly new to being signed on to comply with SDGs.
  • Most sustainability activity is currently planned or just being implemented.
