Concept
- The Joint Crediting Mechanism (JCM) is a bilateral cooperation mechanism that enables countries to jointly implement greenhouse gas (GHG) mitigation projects and share the resulting emission reductions.
- It was originally conceptualised by Japan to promote cost-effective emission reductions while facilitating technology transfer, finance, and capacity building in partner countries.
Linkage with Article 6 of the Paris Agreement
- Article 6 of the Paris Agreement provides voluntary, cooperative approaches that allow countries to achieve their Nationally Determined Contributions (NDCs) more efficiently.
- JCM aligns mainly with Article 6.2, which allows:
- Bilateral or plurilateral cooperation
- Transfer of Internationally Transferred Mitigation Outcomes (ITMOs)
- Use of emission reductions towards NDCs, subject to transparency and accounting rules
Legal and Institutional Context
- Operates within the framework of the and the Paris Agreement.
- Governed by bilateral agreements between Japan and partner countries.
- Each partnership establishes a Joint Committee responsible for:
- Project approval
- Methodology development
- Monitoring, reporting, and verification (MRV)
- Issuance and allocation of credits
Key Objectives
- Promote early and tangible emission reductions.
- Facilitate diffusion of low-carbon and climate-friendly technologies.
- Support sustainable development in host countries.
- Reduce mitigation costs for both investing and host countries.
Operational Features
- Projects are implemented in partner countries, often in sectors like:
- Renewable energy
- Energy efficiency
- Waste management
- Transport
- Industrial processes
- Emission reductions are quantified against a conservative baseline.
- Generated credits are shared between Japan and the host country as per mutual agreement.
- Emphasis on high environmental integrity and avoidance of over-crediting.
Accounting and Transparency
- Credits used under JCM must follow:
- Corresponding adjustments to prevent double counting
- Robust MRV procedures
- Transparency requirements under Article 6 reporting framework
- Ensures that emission reductions are counted only once towards global climate targets.
Difference from Clean Development Mechanism (CDM)
- JCM is bilateral, whereas CDM was a multilateral mechanism under the Kyoto Protocol.
- Focuses more on technology deployment and learning-by-doing, rather than purely offset generation.
- Better aligned with NDC-based climate architecture of the Paris Agreement.
Global Significance
- Acts as a prototype model for implementing Article 6 cooperative approaches.
- Encourages climate finance flows from developed to developing countries.
- Helps operationalise Article 6 rules through real-world implementation experience.
Challenges and Concerns
- Complexity in accounting and corresponding adjustments.
- Limited scale compared to global mitigation needs.
- Need for strong domestic institutional capacity in host countries.
- Ensuring alignment with long-term decarbonisation pathways.
Conclusion
The Joint Crediting Mechanism represents a pragmatic and flexible interpretation of Article 6.2, combining climate ambition with development co-benefits. By enabling bilateral cooperation, technology transfer, and credible carbon accounting, JCM contributes to making the Paris Agreement’s cooperative mechanisms operational, trustworthy, and action-oriented.
