• This paper analyses the risks to environmental integrity associated to the transfers of mitigation outcomes in the context of Art. 6 of the Paris Agreement and provides an overview on approaches and tools that could be used for addressing them. The analysis shows that some of the environmental integrity risks can be dealt with at the technical level. This relates, inter alia, to the risks of mitigation outcomes being unreal or non-permanent as well as to carbon leakage and rebound effects. Here, robust MRV provisions should be established. Other risks will be difficult to address without touching the new and open structure of the Paris Agreement. This applies, for example, to risks associated to the diverse nature of NDCs, and requiresThis paper analyses the risks to environmental integrity associated to the transfers of mitigation outcomes in the context of Art. 6 of the Paris Agreement and provides an overview on approaches and tools that could be used for addressing them.
