The Paris Agreement Crediting Mechanism (PACM) is currently looking for feedback on a new proposed methodology for carbon removal through afforestation and reforestation of lands, except wetlands.
This proposed methodology marks the first instance of the PACM proposing a framework for a nature-based carbon dioxide removal (CDR) pathway.
With the open call for input, carbon market stakeholders now have the chance to review the material and provide their feedback. Launched on November 5, 2026, the call will be accepting submissions by November 26, 2026.
The call is conducted by the UNFCCC Secretariat on behalf of the Article 6.4 Supervisory Body or its supporting panels.
In parallel with the proposed methodology for afforestation and reforestation, the PACM has also released two other proposals that are currently open for feedback. One of them is a methodology for emission reduction through coal quality improvement, and the second one outlines a methodology for rewetting and fire prevention on drained temperate peatlands.
The proposed methodology for CDR through afforestation and reforestation applies to activities taking place on nonwetland territories. The activities include tree planting or assisted natural regeneration on croplands, grasslands or other qualifying non-forest land categories.
In it, the PACM outlines a highly conservative afforestation, reforestation and revegetation (ARR) framework, combining adjusted baselines, a reversal-risk buffer and a century of post-crediting monitoring of 100 years.
To use this methodology, the activity must happen at a location that has not qualified as a “forest” under the definition at any point in the 10 years preceding the planting start, and it should show no trend to reach the forest threshold values in the absence of the activity.
