One key innovation of the Article 6.4 mechanism is its objective to {"}deliver an overall mitigation in global emissions{"} (Art. 6.4(d)). This report develops recommendations on how to implement this objective. A key difficulty lies in the fact that even basics of how the mechanism is supposed to function have so far not been clarified by the Parties. The report therefore first sketches out what has so far been agreed and discussed on the mechanism’s activity cycle. Second, as the concept of overall mitigation has so far also not been clearly defined by Parties, the report derives a working definition from the language that was agreed in the Paris Agreement. In the next step, the report provides a survey of the options to achieve overall mitigation that have so far been discussed in the relevant literature and in the Article 6 negotiations. Many of these options were developed in the context of the Kyoto mechanisms. The report therefore discusses to what extent the options are also applicable under the Paris Agreement or whether adjustments need to be made. In the following, the options that are applicable under the Agreement are assessed on the basis of a number of criteria. The report concludes with a summary of the main findings and recommendations.}, language = {en} }
