Carbon Market Watch’s views on the Article 6.4 Supervisory Body’s recommendations for COP28

Carbon Market Watch advises the CMA against adopting the Supervisory Body's text on removals under the Article 6.4 mechanism without further guidance to ensure environmental integrity. The organization calls for stricter definitions of removal durability, the creation of a science-based risk assessment tool, mandatory post-crediting monitoring, and clear rules on avoidable reversals and buffer pool replenishment. Regarding methodology development, it suggests requiring proponents to prove carbon credit revenues were a significant income source and conducting additionality analyses for different activity types.

• Carbon Market Watch argues that the Supervisory Body's text on removals lacks sufficient detail to guarantee environmental integrity and should not be adopted by the CMA unless further guidance is provided.
• For removal activities under Article 6.4, the organization recommends establishing a mandatory risk assessment tool based on peer-reviewed science that considers geographical context and climate change impacts, and defining a minimum durability for storage while excluding short-term reservoirs.
• The document proposes strict rules for monitoring and reversals, including a minimum post-crediting monitoring period and a requirement that any 6.4ERs from activities with missing or incomplete monitoring reports be deemed reversed and categorized as avoidable reversals.
• Regarding the buffer pool, Carbon Market Watch suggests that proponents must fully replenish the pool at their own expense for avoidable reversals and that unused buffer ERs should be automatically cancelled after the monitoring period.
• On the development of Article 6.4 mechanism methodologies, the organization recommends that proponents demonstrate carbon credit revenues were a significant income source before implementation and that an analysis of additionality likelihood for different activity types be conducted.
