COP29 Successfully Operationalises Article 6 Of Paris Agreement, Unlocking International Carbon Markets
The COP29 Presidency has announced a significant breakthrough in climate negotiations, concluding a decade-long effort to finalise high integrity carbon markets under Article 6 of the Paris Agreement. This achievement was a top priority for the Presidency, which facilitated progress through intensive technical and political discussions. The resolution of this issue marks the completion of the last unresolved aspect of the Paris Agreement.
Article 6 aims to establish reliable and transparent carbon markets that enable countries to collaborate on climate goals. This international cooperation is projected to reduce costs for implementing national climate plans (NDCs) by up to $250 billion annually. The COP29 Presidency urges nations to reinvest these savings into further enhancing their climate ambitions.

The upcoming generation of NDCs, due in February, is crucial for maintaining the target of limiting global warming to 1.5 degrees Celsius. The recent milestone is timely, encouraging countries to commit to more ambitious climate strategies. "We have ended a decade-long wait and unlocked a critical tool for keeping 1.5 degrees in reach," said COP29 President Mukhtar Babayev.
COP29 Lead Negotiator Yalchin Rafiyev highlighted the complexity of Article 6, stating, "Today, we have unlocked one of the most complex and technical challenges in climate diplomacy." He explained that its impacts would be evident in everyday life through actions like decommissioning coal plants and investing in renewable energy projects.
The journey to today's outcome was challenging. Previous COPs in Glasgow and Sharm El-Sheikh established essential rules for carbon markets but left some aspects unresolved. Before COP29, negotiations had stalled, delaying full implementation of this collaborative pathway. The COP29 Presidency's dedicated approach broke through previous stalemates by fostering productive engagement among Parties.
This strategy bridged technical and political discussions, paving the way for early adoption of Article 6.4 standards at the start of COP29. This momentum led to today's breakthrough agreement. The Presidency expressed gratitude to individuals and organisations who worked tirelessly over nearly a decade to achieve this consensus.
Ensuring Environmental Integrity
The decisions adopted today ensure environmental integrity, transparency, and robustness in carbon markets through verified emission reductions and removals. These guidelines are designed to maintain practicality while respecting human rights and supporting sustainable development. They enable countries and project developers to cooperate confidently under the Paris Agreement.
The adoption of these decisions does not signify an end but rather a beginning for continual evolution. Parties can adjust the Article 6 rulebook as they gain experience from its implementation, ensuring it remains effective and inclusive over time.
