PACM Seeks Public Feedback on New Afforestation/Reforestation Methodology for Carbon Removal

The Paris Agreement Crediting Mechanism (PACM) has opened a public comment period on its first proposed methodology for nature-based carbon removal via afforestation and reforestation on non-wetland lands. The draft includes conservative baselines, a reversal-risk buffer, and a 100-year post-crediting monitoring requirement. It also restricts synthetic nitrogen fertilizer, limits soil disturbance to 10% of the area, and requires at least three tree species unless waived. Stakeholders can submit feedback until November 26, 2026. This is the first ARR methodology from the PACM, and it comes alongside separate proposals for coal quality improvement and peatland rewetting. The rules aim to ensure that carbon credits from tree planting are durable and additional. For project developers and buyers, the 100-year monitoring period and conservative baseline are likely to shape credit pricing and project viability. The public comment window is short, so interested parties should review the full text on the UNFCCC site before the deadline.
