Japan’s Intended Nationally Determined Contribution (INDC):
GHG emission reduction target by 2030


Japan’s INDC


Japan’s INDC towards post-2020 GHG emission reductions is at the level of a reduction of 26.0% by fiscal year (FY) 2030 compared to FY 2013 (25.4% reduction compared to FY 2005) (approximately 1.042 billion t-CO2eq as 2030 emissions), ensuring consistency with its energy mix, set as a feasible reduction target by bottom-up calculation with concrete policies, measures and individual technologies taking into adequate consideration, inter alia, technological and cost constraints, and set based on the amount of domestic emission reductions and removals assumed to be obtained.

  • By 2030, Japan’s GHG emissions per GDP are projected to improve by more than 40% and per capita by about 20%, maintaining the status of one of the best performance in the world. This target is ambitious and comparable to other Parties’.
    • Its energy consumption per unit of GDP is even now some 30% lower than the average of the other G7 nations, making it a top performer in the world. Japan will aim for a 35% improvement in energy efficiency by 2030.
    • In the energy mix, the share of renewable energy in total power generation is approx. 22-24% (solar is projected to increase sevenfold from current levels, and wind and geothermal fourfold), while the share of nuclear power is approx. 22-20%.
  • Japan’s INDC is consistent with the long-term emission pathways up to 2050 to achieve the 2 degrees Celsius goal as presented in the Fifth Assessment Report of the IPCC, and with the goal the country upholds, namely, “the goal of achieving at least a 50% reduction of global GHG emissions by 2050, and as a part of this, the goal of developed countries reducing GHG emissions in aggregate by 80% or more by 2050”.
  • The Joint Crediting Mechanism (JCM) is not included as a basis of the bottom-up calculation of Japan’s emission reduction target, but the amount of emission reductions and removals acquired by Japan under the JCM will be appropriately counted as Japan’s reduction.


Trend of GHG emissions per GDP and GHG emissions per capita

  • Japan’s GHG emissions per gross domestic product (GDP) are 0.29 kg-CO2eq./U.S. dollar in 2013 and per capita are 11t-CO2eq./person in 2013, all of which are already at the leading level among developed countries.
  • The indicators noted above are projected to improve by around 20 to 40% by 2030 with further measures to reduce emissions.
