We currently include Scope1 and 2 emissions, and aim to include Scope 3, once data is sufficiently available.


Net Zero Investment Framework

Additional information

Proportion of AUM committed:

We continue to review data availability for sovereign bonds, now. Once we are ready, these assets are to be managed in line with net zero.

Policy on coal and other fossil fuel investments:

No. We will not simply withdraw from investment (divestment) to exclude companies with high greenhouse gas emissions from investment targets. Withdrawal from investment is an easy way to eliminate the company’s involvement, but we believe that even if the assets we manage can be decarbonized, it will not result in decarbonization in the real world. It is our  unwavering policy since we began stewardship activities nearly 20 years ago to work with companies to encourage improvement. Through stewardship activities, we will focus on activities such as engagement with investee companies.
As a responsible institutional investor, we aim to achieve sustainable growth and sustainability for investee companies and all of society by encouraging investee companies to resolve ESG issues through business excellence activities. Going forward, we will add activities through NZAM to continue our efforts in tackling climate change issues and promoting a smooth transition to a low-carbon / decarbonized society.
