We retain this percentage for 10 years in the buffer. The buffer serves as a mechanism to compensate for potential carbon losses (release) during the programme and to give reassurance on the permanence of carbon storage that your certificates represent to buyers. Each time a loss is confirmed during an audit, a corresponding number of certificates will be removed (cancelled) from the buffer to compensate for the loss. Certificates that are placed in the buffer will not be sold until the end of the 10th season after these certificates were generated.
