Submission of Japan's Intended Nationally Determined Contribution (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[1], 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.

[1] The term "energy mix" in this INDC refers to the "Long-term Energy Supply and Demand Outlook" for FY 2030, decided by the Ministry of Economy, Trade and Industry on July 16, 2015.

GHG emissions and removals

1. GHG emissions reductions

(1) Energy-Originated CO2

  Approximately 90% of GHG emissions in Japan is covered by energy-originated CO2. Emissions of energy-originated CO2 will be reduced by 25.0% compared to FY 2013 level (24.0% reduction compared to FY 2005 level) (approximately 927 million t-CO2). The estimated emissions in FY 2030 in each sector are shown in Table 1.

Table 1 Estimated emissions of energy-originated CO2 in each sector

Estimated emissions of each sector in FY 2030 FY 2013(FY 2005)
Energy originated CO2 927 1,235(1,219)

Industry 401 429 (457)

Commercial and other 168 279 (239)

Residential 122 201 (180)

Transport

163 225 (240)

Energy conversion 73 101 (104)

[Value:million t-CO2

(2) Non-energy originated CO2

  The target is set as 6.7% reduction compared to FY 2013 level (17.0% reduction compared to FY 2005 level) (approximately 70.8 million t-CO2).

(3) Methane

  The target is set as 12.3% reduction compared to FY 2013 level (18.8% reduction compared to FY 2005 level) (approximately 31.6 million t-CO2eq.).

(4) Nitrous oxide

  The target is set as 6.1% reduction compared to FY 2013 level (17.4% reduction compared to FY 2005 level) (approximately 21.1 million t-CO2eq.).

(5) Fluorinated gases (HFCs, PFCs, SF6 and NF3)

  The target is set as 25.1% reduction compared to Calendar Year(CY) 2013 level (4.5% increase compared to CY 2005 level) (approximately 28.9 million t-CO2eq.).

2Removals by LULUCF

 The target for removals is set as approximately 37 million t-CO2 (corresponding to 2.6% reduction of total emissions in FY 2013 (corresponding to 2.6% reduction of total emissions in FY 2005)) (approximately 27.8 million t-CO2 by forest carbon sinks measures (corresponding to 2.0% of total emissions in FY 2013 (corresponding to 2.0% reduction of total emissions in FY 2005)), and approximately 9.1 million t-CO2 by cropland management, grazing land management and revegetation (corresponding to 0.6% reduction of total emissions in FY 2013 (corresponding to 0.7% reduction of total emissions in FY 2005))).

3JCM and other international contributions

 Japan establishes and implements the JCM in order both to appropriately evaluate contributions from Japan to GHG emission reductions or removals in a quantitative manner achieved through the diffusion of low carbon technologies, products, systems, services, and infrastructure as well as implementation of mitigation actions in developing countries, and to use them to achieve Japan's emission reduction target. Apart from contributions achieved through private-sector based projects, accumulated emission reductions or removals by FY 2030 through governmental JCM programs to be undertaken within the government's annual budget are estimated to be ranging from 50 to 100 million t-CO2. As part of international contributions other than the JCM, worldwide emission reduction potential in FY 2030 through the diffusion of leading technologies by Japanese industries' actions is estimated to be at least 1 billion t-CO2.

 Japan will also actively contribute internationally towards, inter alia, human resource development and promotion of development and diffusion of technologies relating to emission reductions in developing countries.
