Japan's domestic greenhouse gas emissions dropped to 994 million tonnes in fiscal year 2024, falling below the 1 billion tonne threshold for the first time since 2013, the baseline year for the country's reduction targets. The figure represents a 1.9% decrease from the previous fiscal year. The milestone is significant as Japan works toward its climate commitments under international agreements, with 2013 serving as the reference point against which official reduction goals are measured.
