Yachiyo Engineering Achieves Outstanding CDP Support Results

Yachiyo Engineering Co., Ltd., headquartered in Taito, Tokyo, has announced that approximately 75% of the companies it assisted in responding to the 2025 CDP questionnaire received top leadership ratings of 'A' or 'A-'. This remarkable achievement underscores Yachiyo's role as a trusted partner in sustainability consulting, as it continues to garner praise for driving notable scoring results. Furthermore, the company has been officially recognized as a 'CDP Water Security Certified Partner' for the upcoming 2026 fiscal year, indicative of its commitment to sustainable water management.

Understanding CDP Responses

The CDP, or Carbon Disclosure Project, is an international non-profit organization that requests companies to disclose environmental data concerning climate change, water security, and deforestation on behalf of investors and customers. The scores derived from these responses serve as critical indicators that influence global institutional investors’ decisions regarding ESG investments, impacting companies' market capitalization and financing capabilities.

The increasingly complex CDP questionnaires make it challenging for organizations to attain high scores through mere numerical reporting. Yachiyo offers a comprehensive 'CDP Response Support' service, moving beyond just mock grading and reviews to enhance corporate values through three key approaches.

Yachiyo's Achievements and Strengths

1. High A-Rank Achievement Rate: 75% of assisted companies achieved top ratings
In the 2025 CDP response assistance program, 75% of the companies supported by Yachiyo in all categories – climate change, water security, and forestry – attained the highest accolades of 'A' or 'A-'. This high level of scoring illustrates that Yachiyo's assistance leads to substantial outcomes. By leveraging insights gained from a wealth of experience—259 assessments to date—Yachiyo provides clients with strategic advice that accurately captures the essence of evaluation criteria, ensuring successful score improvements for all corporations involved.

2. Comprehensive Support for Complex Sustainability Disclosures
With extensive experience in various areas such as CDP response assistance, TNFD-LEAP assessments, goal setting in accordance with SBTs for Nature, water risk evaluations, and support for obtaining Alliance for Water Stewardship (AWS) certification, Yachiyo effectively addresses a wide range of sustainability issues, including climate change, biodiversity, and water risk management. As the only company in Japan capable of officially supporting AWS certification, Yachiyo promotes globally recognized water stewardship practices.

3. Ongoing CDP Water Security Certification
Since 2023, Yachiyo has been recognized as a 'CDP Water Security Certified Partner'. As a pioneer in water resource management, Yachiyo has officially collaborated with CDP in this highly data-driven sector.
