ROHM Co., Ltd. (Headquarters: Kyoto, Japan) has been recognized by CDP (formerly the Carbon Disclosure Project), an international environmental non-profit organization, for our environmental strategies and initiatives, securing a place on the 2025 A List for tackling both climate change and water security. This marks the second consecutive year for Climate Change and the fifth consecutive year for Water Security that ROHM has been included in the A List, the highest rating by CDP.

CDP is an international environmental non-profit organization that operates a global environmental disclosure system for companies and municipalities. It conducts environmental information surveys and publishes data regarding Climate Change and Water Security.

The survey is fully aligned with IFRS S2, the climate standard of the International Sustainability Standards Board (ISSB), and its scores are widely used for decision-making on investments and purchasing in a sustainable, resilient, net-zero economy. In 2025, more than 640 financial institutions requested disclosure of environmental impacts, risks, and opportunities through the CDP platform, with approximately 22,100 companies responded. The survey employs an eight-tier evaluation scale with levels ranging from Leadership level (A, A-) to Management level (B, B-), Recognition level (C, C-), and Disclosure level (D, D-), based on criteria such as comprehensiveness of disclosure, identification and management of environmental risks, and ambitious target setting.

＜Environmental Initiatives at ROHM＞

In the Environmental Vision 2050, ROHM has committed to achieving virtually zero greenhouse gas emissions and maximizing resource recycling to eliminate waste of limited resources from all its business activities.

・Water Resource Management
ROHM has set a target to increase the proportion of water recovery and reuse by at least 5.5% by FY2030 (compared to FY2019), and is making efforts to reuse water resources and reduce factory wastewater by globally managing water withdrawal, wastewater, and water usage. Furthermore,to address risks such as flooding, ROHM has established a Business Continuity Management (BCM) system. This includes formulating site-specific risk scenarios and production continuity plans. ROHM is also taking ongoing measures, such as the construction of new production buildings that incorporate flood countermeasures.

・Climate Change Measures
ROHM has set a target to reduce greenhouse gas emissions (Scope 1 and 2) by at least 50.5% by FY2030 (compared to FY2018), and is working globally to reduce consumption through the introduction of environmentally friendly equipment and energy conversion.
Furthermore, ROHM has announced a plan to source 100% of the electricity used in all domestic and international business activities from renewable energy by FY2050. Several sites, including major overseas production sites, are already operating on 100% renewable energy. As of FY2024, ROHM has achieved a 45% adoption rate and plans to increase this to 65% by FY2030.

Encouraged by the evaluation results, ROHM will continue to promote CSR activities and address social issues to achieve a sustainable society and become a company that meets the expectations of its stakeholders.
