Japan’s Ministry of Economy, Trade and Industry plans to conduct an indication undertaking for Environmental Value Certificates for next-generation fuels. The operations of CO2NNEX within the Nagaoka Methanation Demonstration are anticipated to set a precedent for establishing a certificates system, contributing to the sensible software of e-methane and the conclusion of a carbon-neutral society.
