The Japanese Standards Association (JSA), headquartered in Minato-ku, Tokyo (President: Hiroshi Asahi), released a new research report on Greenhouse Gas (GHG) emission calculation rules on April 22, 2026. The JSA Global Research Center provides 'Standardization Intelligence' services, collecting and organizing information on regulatory trends, markets, and standard development to provide insights that lead to the next strategic actions.
### Movements in Rules Related to GHG Emission Calculation
Calculating GHG emissions is a critical task for disclosing climate change information. Calculation methods have been developed by international organizations such as ISO, IEC, and the GHG Protocol. Currently, ISO and the GHG Protocol are revising their standards. In September 2025, both organizations agreed to cooperate in formulating GHG emission calculation rules. Moving forward, these rules are expected to change significantly, potentially having a major impact on corporate information disclosure. This report covers organizational and international standard trends as well as challenges regarding the rulemaking of GHG emission calculations.
JSA has an extensive track record in projects for private companies and Japanese government ministries, including the Ministry of Economy, Trade and Industry (METI), the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), and others.
### Standardization Intelligence Services
