Japan proposes GHG values for addition ethanol sources to expand supply choices
In Japan, on April 17, 2026, Japan’s Ministry of Economy, Trade and Industry (METI) proposed default greenhouse gas (GHG) emission values for three additional ethanol sources. Currently, METI has established GHG emission values for U.S. corn and Brazilian sugarcane ethanol. The three new additions are ethanol derived from Brazilian corn, Thai sugarcane, and Thai cassava.
Currently rules only includes default GHG emission values for U.S. corn-based ethanol and Brazilian sugarcane-based ethanol, which Japanese oil refineries have relied on for imported ethanol.
However, METI seeks to expand the ethanol sourcing options available to Japanese oil refineries. METI requested a contracted advisor to calculate the default life-cycle GHG emission values for ethanol derived from Brazilian corn, Thai sugarcane, and Thai cassava to expand potential supply options.
