At COP30 in Belém, negotiators made a delicate balancing act in the evolving world of global carbon markets. Amid the buzz of side meetings and plenary sessions, key decisions on Articles 6.2 and 6.4 revealed both progress and caution.
While funding and procedural guidance moved forward, many of the toughest questions—how to ensure permanence, manage carbon reversals, and keep projects transparent—were postponed, leaving the next major debates scheduled for 2026.
Financially, the conference delivered concrete steps. The Clean Development Mechanism Trust Fund will transfer $26.8 million to Article 6.4, with up to $5 million more available for capacity-building support in developing nations. This signals the end of an era and paves the way for the so-called Paris Agreement Crediting Mechanism (PACM) to step in the limelight.

These funds aim to strengthen participation and help the new mechanism scale effectively. However, some procedural concerns linger: certain expert-panel meetings may continue behind closed doors, leaving critics uneasy about the openness of decision-making.
Negotiators kept the section on project standards short and broad, setting the stage for deeper discussions on permanence and risk later. Transparency and stakeholder engagement remain key priorities, as countries work to maintain consistency with past climate decisions.
Nature-based projects, particularly forest restoration and carbon removals, are unlikely to see new methodologies approved in 2026, signaling a slower pace for environmental initiatives.

On the trading side, a proposal to block nearly all trades flagged for minor inconsistencies in reports was rejected, preserving flexibility for international carbon exchanges. Delegates agreed instead to hold a dialogue at COP 31 (to be held in Antalya, Turkey,) allowing countries to share lessons and experiences.
Last but not least: term limits for the Article 6.4 Supervisory Body won’t be revisited until 2028. That pause was welcomed as a way to avoid destabilizing the mechanism while it continues to take shape.
This was another example of how COP 30 struck a careful balance between action and caution.
Term-limit debates were deferred, funding for Article 6.4 advanced, and Article 6.2 trading remained alive. Yet transparency challenges and delayed nature-based projects highlight that the carbon market’s path forward is still unfolding.
With the next major discussions scheduled for 2026, negotiators will be leaving Belém with progress in hand but many of the most complex questions unresolved.
