In May 2025, Japan enacted the Amended GX (Green Transformation) Promotion Act. Amendment provisions obligate businesses which have carbon emissions above a designated amount to notify the Minister of Economy, Trade and Industry of their emission targets every fiscal year from fiscal year 2026, following which the Minister shall allocate a business emissions allowance. The GX Acceleration Agency shall establish and operate an emission allowance trading market for conducting emission allowance trading. Other amendment provisions operationalise the fossil fuel surcharge to be collected from fossil fuel extracts from fiscal year 2028.
