Emissions-Free Power Introduced in
All Company-Owned Buildings in Japan and Overseas— Initiatives toward realizing a carbon-free society and RE100 achievement —

As announced in a previous news release,^*1 DAIBIRU CORPORATION (President & CEO: Takashi Maruyama, Head office: Kita-ku, Osaka) has completed the introduction of emissions-free power^*2 in 22 Company-owned domestic and international offices.

In addition to the above, the Company would like to announce that we have completed the transition to emission-free power in two new buildings in Japan (Toranomon Daibiru-East Building, purchased in December 2023, and Midosuji Daibiru Building, completed in January 2024), two residential properties, and three overseas office buildings (63 Ly Thai To in Vietnam and 275 George Street and 135 King Street in Australia). Therefore, the Company now has adopted emissions-free power at total 29 domestic and international properties.^*3

As a result, we have achieved the introduction of 100% emissions-free power, which is a requirement of the RE100 global corporate renewable energy initiative, and will be able to reduce annual CO₂ emissions by about 32,000 tons.^*4 This reduction is equivalent to the emissions of about 19,000 households.

The emissions-free power introduced by the Company is electricity with a Non-Fossil Certificate (with tracking information)*5 compliant with RE100. Since the introduction of emissions-free power in the buildings will result in zero CO₂ emissions from electricity consumed at their offices and stores, it will lead to enhanced corporate environmental evaluation for building tenants.

The Daibiru Group has included “addressing environmental problems” in its Group Code of Conduct and has been proactively working to save energy and promote recycling, etc. Going forward, together with the introduction of emissions-free power, we will continue promoting initiatives toward the realization of a carbon-free society.
