The carbon credit mechanism under Article 6 of the Paris Agreement is one of the key tools to support countries in fulfilling their commitments to reducing greenhouse gas emissions through international cooperation. Article 6 introduces mechanisms that enable countries to achieve emission reductions more effectively by trading carbon credits and collaborating on mitigation activities. Specifically, Article 6 is divided into three main sections.
Article 6.2 – Bilateral or Multilateral Cooperation Mechanism: This provision allows countries to voluntarily cooperate to achieve their Nationally Determined Contributions (NDCs) through Internationally Transferred Mitigation Outcomes (ITMOs). ITMOs refer to emission reductions that one country can purchase from another through greenhouse gas mitigation projects. These credits can be counted toward the NDC targets of the purchasing country.
Article 6.4 – International Carbon Market Mechanism: Article 6.4 establishes a global mechanism to promote emission reductions and support sustainable development. This mechanism, often referred to as the Sustainable Development Mechanism (SDM), plays a crucial role in enabling countries and non-governmental organizations to implement emission reduction projects and receive carbon credits. Through this mechanism, emission reduction projects (such as renewable energy, reforestation, or energy efficiency initiatives) are implemented in one country, generating carbon credits. These credits can be sold to other countries or businesses to help them meet their emission reduction goals. The mechanism ensures genuine emission reductions and contributes to sustainable development, particularly in developing countries. A portion of the revenue from these transactions is allocated to assist vulnerable nations in addressing climate change impacts.
Article 6.8 – Non-Market Mechanisms: Article 6.8 addresses non-market-based cooperative mechanisms aimed at promoting emission reduction measures without necessarily involving carbon credit trading. Countries can collaborate in areas such as technology sharing, capacity building, or technical support programs to achieve emission reduction and climate adaptation goals.
Having outlined the mechanisms of Article 6, it’s essential to consider some key benefits it offers for global climate efforts.
Enhanced Cost Efficiency: Countries or businesses can purchase credits from cost-effective emission reduction projects rather than undertaking more expensive reductions domestically.
Promotion of Sustainable Development: Developing countries can attract foreign investment to implement green projects, fostering economic growth while protecting the environment.
Global Cooperation: Article 6 facilitates collaboration among nations in reducing emissions and ensures that climate commitments are equitably implemented.
Avoidance of double counting: Strict, transparent mechanisms ensure that each carbon credit is accounted for only once, preventing one credit from being counted by two countries.
