Article 6 of the Paris Agreement
Article 6 of the Paris Agreement (2015) establishes the framework for international cooperation in addressing climate change through voluntary mechanisms that enhance ambition and facilitate the achievement of Nationally Determined Contributions (NDCs). It provides the legal basis for countries to collaborate by transferring emission reductions, engaging in market and non-market approaches, and promoting sustainable development. The article is one of the most complex and debated sections of the Paris Agreement due to its implications for global carbon markets and climate finance.
Background
The Paris Agreement, adopted at the 21st Conference of the Parties (COP21) in December 2015, aims to limit global temperature rise to well below 2°C above pre-industrial levels, while pursuing efforts to restrict it to 1.5°C. To achieve these targets, countries submit NDCs outlining their mitigation and adaptation strategies. However, not all countries can reduce emissions at the same pace or cost, making international cooperation mechanisms essential.
Article 6 builds on experiences from the Kyoto Protocol’s Clean Development Mechanism (CDM) and Joint Implementation (JI) but introduces new approaches aligned with the Paris framework, which is universal and bottom-up in nature.
Provisions of Article 6
Article 6 contains three main components:
1. Article 6.2 – Cooperative Approaches
- Allows countries to engage in bilateral or multilateral transfer of emission reductions, known as Internationally Transferred Mitigation Outcomes (ITMOs).
- ITMOs can be applied towards achieving NDC targets, provided that they are:
- Transparent.
- Avoid double counting (claimed by both buyer and seller countries).
- Consistent with environmental integrity.
- Encourages robust accounting methods and reporting to ensure credibility.
2. Article 6.4 – Sustainable Development Mechanism (SDM)
- Establishes a centralised market mechanism, often described as the successor to the Kyoto Protocol’s CDM.
- Overseen by a supervisory body under the Conference of the Parties serving as the Meeting of the Parties to the Paris Agreement (CMA).
- Key features:
- Generates emission reductions that can be used towards NDCs.
- Promotes sustainable development and incentivises private and public sector participation.
- Provides a share of proceeds to support adaptation in vulnerable countries.
- Intended to be more inclusive and stringent than the CDM, ensuring higher environmental standards.
3. Article 6.8 – Non-Market Approaches (NMAs)
- Recognises that cooperation need not always be market-based.
- Focuses on approaches such as:
- Technology transfer.
- Capacity building.
- Finance and policy coordination.
- Designed to foster holistic climate cooperation without relying on carbon trading.
Implementation and Negotiations
Since the Paris Agreement’s adoption, detailed rules for Article 6 have been under negotiation. Disputes have centred on issues such as:
- Double counting: Ensuring emission reductions are not claimed by multiple parties.
- Carryover of old credits: Whether credits from the Kyoto Protocol’s CDM could be used under the Paris Agreement.
- Human rights and environmental integrity: Ensuring projects respect local communities and ecosystems.
- Adaptation finance: Agreeing on the share of proceeds from Article 6.4 to support adaptation.
The Glasgow Climate Pact (COP26, 2021) finalised the rulebook for Article 6, resolving several outstanding issues and enabling operationalisation from 2022 onwards.
Significance of Article 6
Article 6 is crucial for achieving global climate goals:
- Cost efficiency: Countries can achieve emission reductions more cheaply by investing in projects abroad where mitigation is less expensive.
- Private sector engagement: By creating market incentives, Article 6 attracts investment in clean technologies.
- Global solidarity: Non-market approaches support developing countries with finance and capacity-building.
- Raising ambition: Cooperative mechanisms enable countries to pursue more ambitious NDCs than would be possible individually.
Challenges and Criticism
Despite its potential, Article 6 faces several challenges:
- Risk of greenwashing: Poorly designed carbon trading could allow countries to avoid deep domestic emission cuts.
- Equity concerns: Developing countries argue that benefits should not disproportionately favour wealthy nations.
- Complex accounting: Ensuring transparency and avoiding double counting require robust monitoring, reporting, and verification systems.
- Uncertainty of demand: The effectiveness of Article 6 depends on strong participation and demand for carbon credits.
Future Outlook
With the Article 6 rulebook now agreed, the focus has shifted to implementation. Success will depend on:
- Effective governance structures for ITMOs and the SDM.
- Clear rules for transparency and reporting.
- Integration of human rights and sustainable development safeguards.
- Stronger links to climate finance for adaptation.
If implemented effectively, Article 6 could unlock billions of dollars in climate finance, accelerate emission reductions, and play a pivotal role in meeting the 1.5°C target of the Paris Agreement. However, its success will rely heavily on global cooperation, trust, and political will.
