Tsukuba Technology Research Institute certified asa "Natural Symbiosis Site" and also awarded the "Nikkei Award”
Accelerate efforts to achieve nature-positive and carbon-neutral status simultaneously
TODA Corporation (Head Office: Chuo-ku, Tokyo; President: Otani Seisuke) 's greening efforts at the Tsukuba
Research Institute (Tsukuba, Ibaraki) were recognized as a "Natural Symbiosis Site" in October 2023 which theMinistry of the Environment is promoting to achieve the "30 by 30"*1 target. In addition, the Tsukuba ResearchInstitute was selected for the Nikkei Inc. Award in “the Rooftop and Wall Greening Technology Competition”
sponsored by the Organization for Landscape and Urban Green Infrastructure (public interest incorporatedfoundation).

We are actively promoting the following two initiatives① “Nature Positive" aims to halt and restore the loss of biodiversity.
② “Carbon neutral" to reduce overall greenhouse gas emission to zero by 2050
The details are described below.
① Overview of "Natural Symbiosis Site" and certification details
In 2023, the Ministry of the Environment established a new system to certify "areas where biodiversity is
being conserved through private-sector efforts, etc." as "Natural Symbiosis Site," and 122 sites (35prefectures) have now been certified. In addition, those "certified areas" excluding overlapping protectedareas will be registered in the international database as OECM*2, contributing to achieving the "30 by 30"
goal.
The certification covers the green space of the entire grounds ofTsukuba Technology Research Institute. In order to be recognized asa Natural Symbiosis Site, the site had to satisfy one or more itemsin the "Criteria for the Value of Biodiversity" and we wereevaluated in two items: "Ecosystem Services & Healthy Ecosystems" and"Rare Species".
We transplanted and cultivated native species, including rare species
that used to grow in the Tsukuba area, to create a local native plants

biotope and continuously conduct monitoring surveys six times a year
as a Natural Symbiosis Siteto ensure proper maintenance and management. This initiative, in particular,
was recognized by the review committee as contributing to the improvement of
biodiversity in the region, leading to the certification.

② Outline and Selection Details of the Rooftop and Wall Greening Technology Competition
Established in 2002, the competition*3 aims to improve the urban environment and enrich urban lifestyles
and recognizes companies and organizations that actively engage in greening unique spaces such as rooftops
and walls, which were previously considered challenging to green, and are achieving outstanding results.
The award was presented to the greening of the walls of theGreen Office Building, which is used as an office space for
employees of the Tsukuba Technology Research Institute. Unlike
conventional wall greening designed with only outdoor designin mind, this building is also designed with an emphasis on
views from the interior. The four outer walls of the building
were covered with ten types of native vines, which wereevaluated for their ability to shield the building from solar
radiation and provide a biophilia effect*4, making the spacehighly productive for the office workers.

Future Development
With the release of the TNFD (Task Force on Nature-Related Financial Disclosures) recommendations in September
2023, there is an increased focus on corporate activities to conserve and restore natural capital. We will
actively promote greening with an awareness of biodiversity to become "nature positive" and "carbon neutral.”In addition, we will continuously monitor the plants and organisms in the biotopes and greenery at the Tsukuba
Technology Research Institute and use the knowledge gained to contribute to the development of a sustainable
society and the conservation of the global environment through the resolution of issues related to ourcustomers' natural capital.
※1 "30 by 30#
A global goal that seeks to effectively conserve at least 30% of the land and oceans as healthy ecosystems
by 2030.
※2 OECM (Other Effective area-based Conservation Measures)
Lands other than protected areas, such as satochi-satoyama (mountain villages and neighbouring
agricultural, forest, etc. areas), corporate forests, shrine and temple forests, where biodiversity is being
conserved by local communities, companies, and organizations.

Being in contact with nature reduces stress, heals the body and mind, and improves concentration.

We will strive to optimize our business portfolio by promoting strategic investments in priority
management businesses and intangible assets that will drive future growth, and to achieve our mid- tolong-term goal of 8% ROE as well as to further enhance corporate value.
