The press release from Japan Climate Transition Bonds Framework under the Ministry of Finance (MoF) states that on July 2, 2024, Japan will launch its inaugural JPY1.6 trillion (USD 11 billion) Climate Transition Bond, dedicated to funding the nationโs extensive Green Transformation (GX) program.
The GX Plan aims to mobilize JPY150 trillion (USD 1 trillion) in public and private investments over the next decade, targeting cutting-edge, sustainable technologies to mitigate domestic emissions. This initiative aligns with Japan’s commitment to achieving its 46% greenhouse gas (GHG) reduction targets by 2030 and becoming carbon neutral by 2050.
Key Initiatives in Japanโs GX Promotion Strategy
As per the Climate Transition Bond Framework, In FY 2021, Japan’s energy self-sufficiency rate was 13.3%. It has been heavily reliant on imported oil, coal, and liquefied natural gas since the Great East Japan Earthquake occurred in 2011.
Achieving Green Transformation (GX) necessitates addressing high-emission sectors.
Emission reduction efforts are crucial for energy transformation in the following sectors:
- Heavy industries like steel and chemicals, significantly contribute to emissions after distribution.
- Everyday life sectors include households, transportation, commercial, and educational facilities.
Priority will be given to technologies that efficiently and effectively reduce emissions in each sector. The prime focus will be on those that forge industrial competitiveness and drive economic growth.
Japan’s GX promotion strategy establishes two key initiatives to meet international commitments, ensure a stable energy supply, and realize economic growth.
1. Stable Energy Supply and Decarbonization:
- Promote energy conservation measures.
- Transition power sources to improve energy self-sufficiency, focusing on renewable energy and nuclear power.
2. Growth-Oriented Carbon Pricing Concept:
- Implement and execute bold upfront investment support using instruments such as GX Economy Transition Bonds.
- Provide incentives for GX investment through carbon pricing.
- Utilize new financial mechanisms to support the transition.
These initiatives ensure a stable energy supply while advancing toward decarbonization and economic growth.

Japan’s Climate Transition Bonds Set New Standards in Sustainable Finance
The press release discreetly mentions that Japanโs Climate Transition Bonds are certified under the Climate Bonds Standard. It assures investors’ adherence to global best practices in environmental objectives.
Sean Kidney, CEO, of Climate Bonds Initiative, said:
โTransition is the theme for the year: corporates, cities and countries need to do transition plans in line with global emission reduction targets; under the Paris Climate Agreement countries are working on ambitious new Nationally Determined Contributions (NDCs) – transition plans – to be tabled at next yearโs COP. โThis bond shows clearly how governments, and others, can raise funds to invest in that transition. It marks a significant milestone in transition finance.โ
The First 55.5% Share
A substantial 55.5% of the bondโs proceeds will fund R&D initiatives. It would focus on renewable energy and hydrogen utilization in steelmaking, to help limit global temperature increases to 1.5ยฐC.
The Second 44.5% Share
The remaining 44.5% will support subsidies for activities like manufacturing electricity storage batteries and implementing energy-efficiency measures in buildings. Notably, the bond explicitly excludes funding for gas-fired power generation or ammonia co-firing in coal-fired plants.
The independent verification report, prepared by the Japan Credit Rating Agency (JCRA), a Climate Bonds Approved Verifier, reinforces the bondโs credibility.
Atsuko Kajiwara, Managing Executive Officer and head of the Sustainable Finance Evaluation Group at JCRA, said:
โSince 2020, JCR has been contributing to the governmentโs efforts to develop Japanโs transition pathway toward net zero by 2050 and alignment with the Paris Agreement. JCRA hopes the governmentโs strong initiative will help various Japanese corporates that struggle to find a way to attain both carbon neutrality and business expansion in the coming decades.โ
We shall elaborate on the history and additional details of this bond in the next paragraphs.
The development of Climate Transition Bonds (JCTBs) in Japan, IEA Reports
In February 2024, Japan made history by issuing the worldโs first sovereign transition bondsโJapan Climate Transition Bonds (JCTBs). The issuance included two tranches of JPY 800 billion (USD 5 billion) each, with tenors of 5 and 10 years. Certified by the Climate Bonds Initiative, these bonds are grounded in Japanโs national transition strategy.

Unlocking the Key Features of JCTBs
Investment Plan
Japanโs Basic Policy for the Realization of Green Transformation, published in February 2023, outlines a detailed investment plan for 22 industrial sectors to achieve carbon neutrality by 2050.
- Envisions JPY 20 trillion (USD 130 billion) of public capital
- Aims to generate over JPY 150 trillion (USD 1 trillion) in investment through public and private financing by 2050
- Includes sector-specific transition roadmaps developed by expert committees
Focus on Nascent Technologies
Over half of the proceeds from JCTBs will be allocated to emerging technologies crucial for the transition.
Innovative Carbon Pricing Approach:
- Utilizes future carbon pricing revenue for immediate bond repayment
- Allows for immediate deployment of capital based on assumed future revenue from carbon taxes
Potential for Emerging Markets and Developing Economies (EMDE):
- Credit Intermediary Role: The government acts as a credit intermediary, enhancing the creditworthiness of corporates and simplifying financing for small-scale projects.
- Credit Enhancements: For countries with sub-investment-grade credit ratings, additional credit enhancements such as guarantees from Development Finance Institutions (DFIs) may facilitate access to international capital markets.
Japan’s climate transition bonds set a new standard for sovereign transition bonds. This model can guide other nations, especially in emerging markets. Consequently leveraging future carbon pricing revenues and attract significant investment for green transformations.
