Biodiversity conservation

Biodiversity risk assessment

To meet requirements for corporate disclosure such as EU-CSRD (Corporate Sustainability Reporting Directive), we have been preparing our information disclosure with an outside consultant. Our group’s risk and opportunity analysis on biodiversity and ecosystems are under evaluation according to the LEAP approach* etc., which TNFD (Taskforce on Nature-related Financial Disclosures) recommends.

*the LEAP approach: It consists of 4 phases, “Locate” corporate’s interface with nature, “Evaluate” corporate’s dependencies and impacts on nature, “Assess” corporate’s nature-related risks and opportunities, and “Prepare” to respond to nature-related risks and opportunities and to report on corporate’s material nature-related issues. This approach can help to discover dependencies, impacts, potential risks, and opportunities between corporate’s activities and nature.

Contribution to local environmental conservation

We recognize the importance of environmental conservation. As part of our efforts to conserve the local environment, our employees have joined tree-planting campaigns, clean-up activities, and so on.

Clean-up campaigns aligned with the Biodiversity Hamamatsu Strategy

Hamamatsu Photonics participates in the “Hamamatsu Biodiversity Strategy,” which aims at biodiversity conservation in Hamamatsu region. We have promoted it through joining environmental activities, such as yearly “Lake Hamana Clean-up Campaign.” In FY2024, a total of 624 employees had joined clean-up campaigns around our offices (15 times) and other environmental events (including Lake Hamana Clean-up Campaign) (5 times).

“Happy Memorial Trees” program

Happy memorial trees

To promote biodiversity and raise awareness of environmental issues, Hamamatsu Photonics has run a unique program “Happy Memorial Trees” since October 2011 which distributes plants to employees who bought a house, married, and whose child enrolled in elementary school. The photos shown here were provided by employees in commemoration of planting. As of FY2024, a total of 1,310 employees had applied for this program since FY2011.

Many trees are planted on our office premises too, and it contributes to beautifying and maintaining the environment.  In addition, some offices try to make “green curtains” (sunshade curtains made of vines) in the summer season.
