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.
