TAIYO YUDEN Selected as a Supplier Engagement Leader, the Highest Rating in CDP's Assessment, for Three Consecutive Years

TOKYO, July 30, 2025 - TAIYO YUDEN CO., LTD. has been selected by the international environmental non-profit organization CDP as a Supplier Engagement Leader, the highest A rating in its Supplier Engagement Assessment (SEA), for three consecutive years. The objective of the SEA is to assess measures implemented by the company to address climate change across its supply chain.

Background
In its Medium-term Management Plan 2025, the TAIYO YUDEN Group includes enhancement of its climate change countermeasures in its materiality (material issues), aiming to enhance its corporate value through the combination of economic and social value.
For reducing greenhouse gas (GHG) emissions in particular, we have set reduction targets to achieve by FY2030 based on emissions category―42 % (compared to FY2020) for Scopes 1 and 2 and 25% (compared to FY2021) for Scope 3 (Category 1 and 3) ; and for all of them, we have obtained SBT certification. Especially to accelerate efforts regarding Scope 3, which represents indirect emissions that occur outside of the company's direct control but throughout its supply chain, we are enhancing our approach to suppliers, chiefly by encouraging them to step up reduction efforts and providing support with emissions calculations.
Based on the recognition that ESG-related measures, including those against climate change, pose both opportunities and risks to its business management, the TAIYO YUDEN Group is conducting activities to solve social issues through its business operations. Going forward, the TAIYO YUDEN Group will continue to contribute to the sustainability of society and further increase its corporate value through manufacturing based on the principle of decarbonization.
