Tokyo, May 22, 2026 – Hitachi High-Tech Corporation ("Hitachi High-Tech")has recently scored the highest rating in the Supplier Engagement Assessment (SEA) performed by the CDP (Carbon Disclosure Project, headquartered in the UK), a non-profit organization that conducts environmental research and information disclosure globally, and has been selected as a Supplier Engagement Leader. Approximately the top 10% of all companies who responded to the CDP’s questionnaires were selected as Supplier Engagement Leaders.
Hitachi High-Tech works together with our procurement partners to reduce greenhouse gas ("GHG") emissions throughout our entire supply chain, and we have been highly rated for our various initiatives. In December 2025, Hitachi High-Tech was also selected as an A-List company, the highest rating available, in the Climate Change and Water categories.
For two consecutive years, Hitachi High-Tech has achieved the highest ratings across three categories, including collaboration with procurement partners.
Working from our business characteristics and management foundations, we identified what social issues we should work to solve and have set five Sustainability Focus Areas*1 where we will contribute to realizing a society where these social problems are solved and sustainability is enabled through our business activities. One of our identified Sustainability Focus Areas is "Contributing to the Sustainable Global Environment," involving initiatives for realizing a recycling oriented society such as the effective use of water resources.
Hitachi High-Tech Group will continue to create environmental value in the entire value chain by promoting various initiatives for achieving carbon neutrality and by reducing the environmental impact of manufacturing and strengthening environmental management. We will contribute to achieving a harmonized society where environment, wellbeing, and economic growth are in balance.
