Article 6 Of The Paris Agreement

  • 21st May, 2025

  • After over a decade of negotiations, the rules under Article 6 of the Paris Agreement governing international carbon trading have been finalized. 
  • This marks a major step in enhancing global cooperation for climate action.

What is Article 6?

  • Article 6 provides a framework that allows countries to cooperate voluntarily to meet their Nationally Determined Contributions (NDCs) targets them set under the Paris Agreement to reduce greenhouse gas (GHG) emissions.
  • This cooperation can happen via carbon markets, which allow for the transfer of emission reductions between countries, or through non-market-based mechanisms aimed at broader climate collaboration.

What is a Carbon Market?

  • A carbon market allows entities (countries or companies) to buy carbon credits to offset their greenhouse gas (GHG) emissions.
  • 1 carbon credit = 1 metric tonne of CO (or equivalent GHG) reduced, removed, or avoided.
  • First introduced under the Kyoto Protocol (1997).

Mechanisms under Article 6

Article

Type

Key Features

6.2

Market-based (Decentralized)

Bilateral trading of emission reductions called ITMOs (Internationally Transferred Mitigation Outcomes). 

Requires corresponding adjustment in NDCs.

6.4

Market-based (Centralized)

Known as the Paris Agreement Crediting Mechanism (PACM). 

Establishes a global carbon market using a baseline-and-crediting system.

6.8

Non-market-based

Promotes mitigation and adaptation through cooperation, without emission trading. 

Focuses on capacity-building, finance, and technology transfer.

What is Corresponding Adjustment (under 6.2)?

  • Adjustments made in a country's emissions inventory to account for the transfer or receipt of ITMOs.
  • Applies to:
    • GHG metrics (e.g., national GHG emission limits)
    • Non-GHG metrics (e.g., installed renewable energy capacity)
    • Policies and measures (e.g., energy efficiency programs)

Why Article 6 of the Paris Agreement Matters

Facilitates International Climate Cooperation

  • Article 6 provides a framework for countries to collaborate in achieving their climate goals (NDCs), enhancing global solidarity in combating climate change.

Mobilizes Finance for Developing Countries

  • Through market mechanisms, developing nations can attract investments for climate-resilient and low-carbon development projects, bridging the climate finance gap.

Promotes Transparency and Environmental Integrity

  • By requiring corresponding adjustments and robust accounting, Article 6 ensures that emission reductions are real, verifiable, and not double-counted.

Strengthens Global Adaptation Efforts

  • A portion of the revenue from carbon market transactions (under Article 6.4) is directed to the Global Adaptation Fund, supporting vulnerable countries in building climate resilience.
