Sources: 5. Developments: 2. Japan is advancing decarbonization efforts through the development of certification systems for next-generation fuels and the creation of consumer demand for low-carbon products. Initial initiatives focused on establishing a ‘Clean Fuel Certificate System’ to certify and trade the environmental value of synthetic methane and biogas. This project aims to mitigate high production costs by providing an objective mechanism to prove CO2 reduction benefits. Concurrently, the Ministry of the Environment began testing models to display the decarbonization value of products to consumers to influence purchasing behavior. Building on these efforts, Hitachi and Tokyo Gas launched a digital demonstration titled ‘Powered by Carbon Neutral Gas’. This technology allows for the digital verification of imported biomethane usage at the level of specific equipment. By integrating data from supply points and meters, the system provides verifiable evidence of zero CO2 emissions for gas-powered heating and cooling. The companies intend to expand this digital platform to include e-methane, hydrogen, and ammonia. ## Timeline ### 2026-08-31: Hitachi and Tokyo Gas launch digital certification for biomethane Hitachi and Tokyo Gas have begun demonstrating a digital solution to certify the use of imported biomethane in specific equipment, providing verifiable evidence for decarbonization efforts. 3 sources. https://clstr.news/cluster/hitachi-and-tokyo-gas-launch-digital-certification-for-biomethane ### 2026-08-26: Japan advances decarbonization via fuel certification and demand creation Japan is advancing decarbonization through a new ‘Clean Fuel Certificate System’ for synthetic methane and biogas, alongside Ministry of the Environment projects to boost demand for low-carbon products. 2 sources. https://clstr.news/cluster/japan-advances-decarbonization-via-fuel-certification-and-demand-creation --- Cite as: Japan decarbonization fuel certification initiatives.
