Understanding and Reducing Environmental Risks in Investment Decisions and Monitoring

Regarding due diligence for new investments, NBF obtains an understanding of environmental and social risks by utilizing external experts and uses this information in its investment decisions. Periodic monitoring of environmental and social risks is conducted for existing properties under management as well and initiatives that provide opportunities for reducing risks and increasing property value are carried out, e.g., expert building assessments such as "Energy Efficiency Walkthroughs".

Co-Existence with the Mitsui Fudosan Group in Redevelopments

The environmental load and environmental risks of the portfolio are reduced through investing in properties with excellent environmental performance that were redeveloped by the Mitsui Fudosan Group under the co-existence model with the Mitsui Fudosan Group.
