The utilization of hydrogen as an energy carrier is promoted in major countries as one of the effective climate change
countermeasures. For the effective use of hydrogen, emissions reduction effect must be evaluated throughout the entire supply chain. The calculation method of greenhouse gas (GHG) emissions and reduction effect have been standardized by the Ministry of the Environment, Japan (MOEJ). MOEJ has developed the LCA (Life Cycle Assessment) Guideline for hydrogen producers, distributors, and end users to evaluate their businesses in Japan. Additionally, the LCA Calculation Tool, manual, and samples were provided and made available on the website of MOEJ.
