Japan’s net greenhouse gas emissions fell to 994 million tons in FY2024, the lowest level in over a decade, dropping below 1 billion tons for the first time since 2013.
Emissions are now 28.7% below 2013 levels, reflecting steady efficiency gains and gradual shifts in the energy mix, but still fall short of the country’s 46% reduction target for 2030.
Industrial and transport sectors recorded continued declines, while household emissions showed only marginal improvement and some service sectors saw slight increases, highlighting uneven progress across the economy.
Slower expansion of non-fossil energy and relatively flat household energy demand remain key constraints on deeper decarbonization.
Japan’s trajectory underscores both meaningful structural progress and the challenge of accelerating reductions to meet its 2030 climate commitments.
