To deliver overall mitigation in global emissions (OMGE), the Article 6 agreement requires the mandatory cancellation of a minimum 2% of Article 6.4 credits. This only delivers a benefit to the atmosphere if a “corresponding adjustment” is applied to these credits, since this ensures the credit is not counted by anyone. For all authorised credits, this is already required, and so there is no problem here. However, since “non-authorised” credits may be possible under Article 6.4, some countries have argued that corresponding adjustments do not need to apply to the 2% OMGE portion levied for non-authorised credits. In practice, this would mean that OMGE would not happen, which is unacceptable. Therefore, it must be a requirement to apply a corresponding adjustment to the minimum 2% OMGE portion levied for all credits, including “non-authorised” ones.
