e-dash to Host May 27 Webinar for Building Materials Manufacturers on CO₂ Emissions Calculation and Third-Party Verification Ahead of Japan’s Building LCCO2 Assessment System

e-dash Inc. announced that it will hold a free online seminar for building materials manufacturers on Wednesday, May 27, 2026, titled “CO₂ Emissions Calculation and Third-Party Verification to Prepare for the Launch of Building LCCO2 Assessment: Latest Trends and How to Use Subsidies.” The seminar will be co-hosted with Intertek Certification Japan Ltd., which has extensive experience in third-party verification of greenhouse gas emissions. As Japan works toward carbon neutrality by 2050, CO₂ reduction efforts for buildings are increasingly focused not only on the use phase but also on the entire life cycle, from material manufacturing to demolition. The Japanese government is currently considering the launch of a system around fiscal 2028 to encourage LCCO2, or life cycle carbon, assessments for buildings. As a result, building materials manufacturers are expected to prepare accurate emissions intensity data showing how much CO₂ their products emit during the manufacturing process. Such detailed data will become an essential foundation for developers and general contractors when evaluating buildings. With disclosure requests growing across the industry, accurately calculating emissions and ensuring objective credibility through third-party verification have become urgent issues that could affect future business continuity and competitiveness for building materials manufacturers. In the seminar, e-dash will explain practical methods for calculating CO₂ emissions based on the latest trends, as well as ways to use subsidies to reduce cost burdens. Intertek Certification Japan will introduce key points for undergoing third-party verification and practical considerations during the preparation stage from a professional perspective. The seminar is aimed at companies seeking to reduce the cost burden of CO₂ emissions calculation and third-party verification through subsidies, those that have received disclosure requests from major developers or general contractors or wish to start preparing, and those that want to understand third-party verification and organize their future response policies. The event will be held from 4:00 p.m. to 5:00 p.m. on Wednesday, May 27, 2026, with admission opening at 3:55 p.m. It will be conducted as a Zoom webinar and is free to attend. The organizers are e-dash Inc. and Intertek Certification Japan Ltd. Speakers include Kenichi Ishizuka, Head of CFP Business and Vice President of the Solution & Advisory Department at e-dash, and Atsunori Nishizono, Sustainability Assurance Business Development Manager at Intertek Certification Japan. Ishizuka holds a master’s degree in engineering and joined e-dash in August 2025 after working in research and technology development at a major chemical company, a foreign strategic consulting firm, and a major engineering company. He currently leads carbon footprint calculation and utilization initiatives for manufacturers and other companies. Nishizono completed graduate studies at Kyoto University and moved into sustainability after working in IT and business. He currently leads the development of sustainability-related audit programs and also works as an ISO 14001, GHG, and CFP verifier, supporting companies in improving credibility from the front lines of verification. e-dash was established on February 7, 2022, with shareholders including Mitsui & Co., Ltd. and Mizuho Innovation Frontier Co., Ltd.
