A new study published in Nature reveals that US forest carbon offset programs significantly underestimate the risk of carbon reversal. Climate driven disturbances, particularly wildfires, threaten the permanence of stored carbon, making many current offset projects unreliable over the long term. Researchers argue that existing buffer pools, which act as insurance for lost carbon, are too small to cover projected losses. The study suggests that carbon markets must integrate updated climate modeling to prioritize low risk regions and increase reserve requirements to maintain environmental integrity.
