Why in the News?
India and Japan jointly launched the Operational Manual for their Joint Crediting Mechanism (JCM) in New Delhi on 30 September 2026. The Ministry of Environment, Forest and Climate Change announced the development on 5 October 2026.
The launch followed three important milestones:
- 7 August 2025: India and Japan signed the Memorandum of Cooperation establishing the JCM.
- 8 June 2026: Both countries adopted the Rules of Implementation.
- 30 September 2026: The Operational Manual was launched, setting out procedures for the mechanism’s project cycle, from project proposal to credit issuance and authorisation.
The initiative operates under Article 6.2 of the Paris Agreement. It aims to promote low-carbon technology, mobilise climate finance, facilitate technology cooperation and support credible greenhouse-gas emission reductions and removals in India.

1. What is the Joint Crediting Mechanism?
The Joint Crediting Mechanism is a bilateral climate-cooperation framework between India and Japan. It enables cooperation on projects that reduce or remove greenhouse-gas emissions, with the resulting mitigation outcomes measured and credited under mutually agreed rules.
In simple terms, Japanese and Indian participants can cooperate to deploy cleaner technologies in India. If a project achieves eligible emission reductions and meets the mechanism’s requirements, those reductions may be verified and credited under the JCM.
The mechanism has four central objectives:
- Technology cooperation: Encourage the deployment of advanced low-carbon technologies.
- Climate finance: Help mobilise investment for eligible emission-reduction projects.
- Emission reduction: Support measurable reductions or removals of greenhouse gases.
- Sustainable development: Align climate projects with India’s wider development priorities.
The JCM is not a general agreement to sell unlimited carbon credits. Projects must follow the applicable procedures, accounting requirements and approval arrangements.

2. First understand carbon credits
A carbon credit is a unit representing a specified amount of greenhouse-gas emission reduction or removal under the rules of a particular crediting system. In many carbon-credit systems, one credit represents one metric tonne of carbon dioxide equivalent (CO₂e).
What does CO₂e mean?
Different greenhouse gases have different warming effects. Carbon dioxide equivalent converts the warming impact of gases such as methane and nitrous oxide into a common measurement using their global-warming potential.
For example, a project might replace an inefficient industrial process with a cleaner alternative. If its emissions are demonstrably lower than an appropriate baseline, the eligible difference may be quantified. After the required validation, monitoring and verification, the project may qualify for credits under the applicable rules.
Three terms are important:
- Emission reduction: Greenhouse gases released into the atmosphere are reduced.
- Emission removal: Greenhouse gases are taken out of the atmosphere and stored.
- Carbon credit: A unit issued under a specified system to represent an eligible mitigation outcome.
A credit is not proof that a project is completely emission-free. Nor does purchasing a credit automatically eliminate every environmental impact associated with a company or country.
3. How does the India–Japan JCM work?
The mechanism follows a structured project cycle.
Step 1 — Project identification
A project proponent identifies a possible activity that could reduce or remove greenhouse-gas emissions through cleaner technology or another eligible intervention.
Step 2 — Project proposal
The project is submitted through the applicable JCM documentation and procedures. The proposal must explain the activity, its expected emission reductions, the methodology and other required information.
Step 3 — Assessment and approval
The project is examined under the mechanism’s approval framework. The bilateral Joint Committee provides institutional oversight, with representatives from both governments.
Step 4 — Validation and monitoring
The project must meet applicable technical requirements. Its performance and emission reductions are monitored according to the approved methodology.
Step 5 — Independent verification
A qualified third party assesses whether the project and its reported mitigation outcomes meet the relevant requirements.
Step 6 — Credit issuance and authorisation
Eligible credits can be issued and authorised only through the applicable procedures. Registries and accounting arrangements help track credits and their transfers.
The Operational Manual establishes procedures across this project cycle. Its launch marks a move from institutional preparation towards implementation; it should not be interpreted as proof that a particular quantity of credits has already been issued or traded.

4. Article 6 of the Paris Agreement: the most important UPSC concept
The Paris Agreement, adopted in 2015 under the United Nations Framework Convention on Climate Change (UNFCCC), provides the international framework for addressing climate change.
Article 6 enables countries to cooperate voluntarily in implementing their climate commitments. Its three principal components must be clearly distinguished.
| Provision | What it covers | UPSC takeaway |
|---|---|---|
| Article 6.2 | Cooperative approaches involving internationally transferred mitigation outcomes (ITMOs) | Relevant to the India–Japan JCM |
| Article 6.4 | A mechanism established under the Paris Agreement for crediting emission reductions | Distinct from Article 6.2 |
| Article 6.8 | Non-market approaches to international climate cooperation | Cooperation without relying on carbon-credit trading as the central mechanism |
Remember: The India–Japan JCM operates under Article 6.2, not Article 6.4.
What are ITMOs?
ITMO stands for Internationally Transferred Mitigation Outcome.
An ITMO is a mitigation outcome transferred internationally under the applicable Article 6.2 rules and accounting framework. Such outcomes may be used towards climate targets only in accordance with the relevant requirements and authorisations.
An ordinary carbon credit and an ITMO are not automatically interchangeable in every context. The governing mechanism, authorisation, intended use and accounting treatment matter.
What is a corresponding adjustment?
Corresponding adjustments are an accounting safeguard under Article 6.2 designed to prevent the same mitigation outcome from being counted towards the climate targets of two countries.
Suppose an eligible emission reduction generated in India is authorised for international transfer and used by Japan towards its Nationally Determined Contribution. The applicable accounting rules require corresponding adjustments so that both countries do not claim the same outcome towards their respective targets.
This does not mean that the physical emissions reduction disappears. It means that the countries must account for the transfer consistently.
What are Nationally Determined Contributions?
Nationally Determined Contributions (NDCs) are the climate action commitments that countries prepare and communicate under the Paris Agreement. They describe national efforts to reduce emissions and, as applicable, address adaptation and other climate priorities.
The JCM is intended to contribute to the NDCs of both India and Japan, subject to the mechanism’s rules.

5. Why is the JCM important for India?
A. Mobilising climate finance
Cleaner industrial equipment, energy-efficient processes and low-carbon infrastructure can require substantial upfront investment. A credible crediting framework can create additional incentives for eligible projects and help attract private-sector participation.
However, the availability and cost of finance will depend on project economics, investor confidence, credit demand and the applicable rules.
B. Access to technology
International cooperation can facilitate the deployment and adaptation of advanced low-carbon technologies in India. Potential applications depend on project eligibility and may include industrial energy efficiency, renewable energy-related technologies and other emissions-reduction activities.
Technology transfer should ideally strengthen Indian technical expertise, domestic manufacturing capabilities and long-term innovation rather than create unnecessary dependence on imported equipment.
C. Industrial decarbonisation
Industries such as steel, cement and chemicals face challenges in reducing emissions while remaining competitive. Eligible cleaner technologies and more efficient production processes may help address these challenges.
The JCM’s actual contribution will depend on which projects are approved and how effectively they reduce emissions.
D. Sustainable development
Climate projects can provide benefits beyond emissions reduction, including improved energy efficiency, skills development, cleaner industrial production and potentially better local environmental outcomes.
These benefits should be assessed rather than automatically assumed. A project’s social and environmental consequences matter alongside its carbon performance.
E. Strengthening India–Japan relations
The mechanism adds a climate and technology dimension to the India–Japan Special Strategic and Global Partnership. It connects bilateral cooperation with economic development, technological innovation and international climate commitments.
For India, the challenge is to secure meaningful development benefits while maintaining credible carbon accounting and protecting national interests.
6. What does Japan gain?
The cooperation is designed to support the climate commitments of both countries.
Japan can contribute technology, investment and technical expertise to eligible projects in India. Under the relevant rules, authorised mitigation outcomes may contribute to Japan’s NDC accounting.
India, meanwhile, can benefit from cleaner technologies, investment and domestic development outcomes. The distribution of benefits will depend on project design, financing terms, technology access and the rules governing credits.
The mechanism is therefore a framework for cooperation, not a guarantee that every project will benefit both countries equally.
7. Carbon markets: compliance versus voluntary markets
UPSC aspirants should distinguish between two broad categories of carbon markets.
Compliance carbon markets operate under mandatory legal or regulatory obligations. Covered entities may need to meet prescribed requirements, depending on the system.
Voluntary carbon markets involve entities purchasing credits voluntarily, often to support climate strategies or make claims about their emissions.
The India–Japan JCM is a bilateral cooperation mechanism under Article 6.2. It should not be casually described as simply a voluntary carbon-offset marketplace. The rules governing authorisation, international transfer and use towards NDCs are essential to understanding its operation.
A related Indian policy development is the Carbon Credit Trading Scheme, which provides the framework for India’s domestic compliance carbon market. The domestic scheme and the bilateral JCM are related to carbon-market development but are not the same mechanism.
For UPSC, remember that a carbon tax, an emissions-trading system and a crediting mechanism are different policy instruments.
- A carbon tax places a price on emissions through taxation.
- An emissions-trading system establishes a regulatory framework for trading emission allowances.
- A crediting mechanism issues credits for eligible emission reductions or removals under specified rules.
8. Major challenges and safeguards
The JCM’s success will depend on the credibility of the emission reductions it recognises.
Environmental integrity
Projects must produce genuine emission reductions or removals. Inflated estimates or weak monitoring could undermine the value of credits.
Additionality
Additionality asks whether the claimed mitigation benefit is genuinely attributable to the project beyond what would have occurred under the relevant baseline or counterfactual scenario.
Baseline selection
A baseline estimates what emissions would have been without the project. If the baseline is unrealistically high, the project may appear to deliver more reductions than it actually does.
Double counting
The same mitigation outcome must not be claimed towards the climate targets of multiple countries in a manner prohibited by the applicable rules. Corresponding adjustments and transparent accounting are important safeguards.
Measurement, reporting and verification
Reliable monitoring and independent verification are essential to establish the credibility of emission reductions. Weak data or inadequate oversight could undermine confidence in the mechanism.
Equitable sharing of benefits
Project developers, investors, technology providers and host communities may have different interests. Clear agreements should address financing, technology access, project benefits and relevant environmental and social safeguards.
Development priorities
Climate cooperation should support India’s development needs. Project selection should consider affordability, domestic capacity, local environmental conditions and long-term sustainability.
9. The way forward for India
India can strengthen the mechanism through five priorities:
- Transparent project selection: Publish clear eligibility criteria and relevant project information.
- Robust verification: Apply credible methodologies, independent assessment and reliable monitoring.
- Strong accounting: Maintain accurate registries, authorisation procedures and corresponding adjustments where required.
- Domestic capacity-building: Develop Indian expertise in carbon measurement, verification, clean technology and project development.
- Development-centred cooperation: Evaluate projects on emission reductions as well as their economic, technological and social benefits.
The objective should be to attract climate finance without compromising environmental integrity, domestic development priorities or India’s ability to account accurately for its climate commitments.India Is Growing Strong. Inflation Is Rising. RBI Turns to “Calibrated Tightening

11. UPSC Prelims Previous-Year Question (PYQ)
UPSC Civil Services Preliminary Examination 2025 — General Studies Paper I
The examination included a question on Article 6 of the Paris Agreement, testing its relationship with carbon markets and international non-market approaches.
The question examined whether Article 6 establishes principles for carbon markets and promotes cooperation through non-market approaches to achieve climate targets.
Correct answer: Both statements are correct, and both explain the importance of Article 6 in global climate discussions.
Why this PYQ matters: It demonstrates that UPSC can test the architecture of an international climate agreement rather than merely ask when it was signed. Aspirants should understand the distinction between Articles 6.2, 6.4 and 6.8.

13. UPSC Mains practice — GS Paper III
Question (250 words): Explain how bilateral carbon-crediting mechanisms such as the India–Japan Joint Crediting Mechanism can contribute to India’s climate objectives. Discuss the challenges of environmental integrity, carbon accounting and equitable climate cooperation.
Model answer
Bilateral carbon-crediting mechanisms facilitate international cooperation by connecting investment, technology deployment and verified greenhouse-gas emission reductions. The India–Japan Joint Crediting Mechanism operates under Article 6.2 of the Paris Agreement and provides a framework for such cooperation.
Significance for India
First, the mechanism can mobilise finance for eligible low-carbon projects and support the deployment of advanced technologies. Second, it can facilitate industrial decarbonisation, renewable-energy integration and more efficient production processes. Third, technology cooperation and capacity-building can strengthen domestic capabilities and contribute to India’s Nationally Determined Contribution.
Challenges
- Environmental integrity: Mitigation outcomes must be genuine, measurable and additional.
- Carbon accounting: Transparent registries and corresponding adjustments, where required, help prevent double counting.
- Equity: Project benefits, financing risks and technology access must be addressed fairly.
- Domestic development: Projects should complement India’s energy access, industrial growth and sustainable-development priorities.
- Transparency: Independent verification, credible methodologies and appropriate safeguards are essential.
Way forward
India should maintain transparent approval procedures, robust measurement and verification, accurate carbon accounting and strong environmental and social safeguards. Domestic technical capacity should be strengthened to assess project quality and maximise local benefits.
Conclusion
The India–Japan JCM can advance climate cooperation and sustainable development if its implementation combines credible emission reductions with transparent accounting, equitable benefits and India’s long-term development priorities.
Conclusion: Why this matters for UPSC
The India–Japan Joint Crediting Mechanism illustrates how international relations, environmental governance and economic policy intersect. Its importance lies not only in bilateral cooperation but also in the practical application of Article 6 of the Paris Agreement.
For UPSC aspirants, the essential takeaways are the JCM’s bilateral nature, its Article 6.2 basis, the role of ITMOs and corresponding adjustments, and the need to balance carbon-market integrity with development priorities.
One-line revision: India–Japan JCM = bilateral climate cooperation under Article 6.2 + low-carbon technology + climate finance + verified mitigation outcomes + safeguards against double counting.
