Operationalising an ‘overall mitigation in global emissions’ under Article 6 of the Paris Agreement

Article 6 of the Paris Agreement establishes a framework for international cooperation that enables countries to engage in international carbon market mechanisms. Article 6.4 establishes a new crediting mechanism with international oversight. A key requirement of this new mechanism is that it “shall aim to deliver an overall mitigation in global emissions” (Article 6.4(d)). In the ongoing negotiations on the international rules governing the Paris Agreement, countries have different views on what exactly this requirement means and how it should be operationalised and implemented. This report identifies and discusses key options for operationalising this concept.
