The Paris Agreement requires its signatory states (the so-called parties) to regularly formulate their own climate change plans, known as fixed national contributions (NDCs), and to implement measures that will help them achieve their climate change goals.  However, there is no international obligation for contracting parties to achieve their NDCs.  The implementation modalities agreed at the Katowice climate change conference include three steps: The question of whether to limit global inventory to mitigation or to include other aspects such as adaptation and climate finance has been the subject of controversial debate. However, on the eve of the Paris climate change conference, the prevailing view was that all three global inventories should be taken into account.  As part of the overall inventory, Article 14 of the Paris Agreement lists adaptation as well as means of implementation and assistance.  In Phase 3, the results of the evaluation are integrated into the political process. The aim is to help the parties to the Paris Agreement improve both their climate change policy and the measures they are taking to support other contracting parties. The results will also be used to promote international cooperation. On this point, it is not known how to document the results – perhaps a political statement, or even a formal decision of the Conference of the Parties. In this way, it is hoped that the Global Stocktake will become a will for impulse. It should be noted, however, that Global Stocktake takes a collective approach rather than an individual approach. This means that some countries should not be highlighted and that the results of the inventory should not be used to draw conclusions about the state of implementation in the various Member States.  The first Global Stocktake will take place in 2023.
 However, the transparency framework established by the Paris Agreement, which requires each state to report on the progress of the implementation of its national targets and emissions, will not come into force until 2024. Given that the transparency reports of the parties are an important source of information for the completion of the global inventory, the world`s largest inventory must be based on previous reporting obligations. However, they present many information gaps and it is not known to what extent these gaps can be filled by other sources of information. For example, more use can be made of the analyses and recommendations of non-governmental actors, including civil society initiatives, businesses and municipalities. Another aspect that still needs to be developed is the precise date of the three phases of global stocktake. In particular, it is important to ensure that the results of the process are completed in a timely manner and prepared so that they can be properly considered in the development of the parties` CNN. The Global Stocktake aims to strengthen ambitions by helping the parties to do so: The Paris Agreement marked a turning point in international climate policy. These are not only ambitious global targets, such as limiting the increase in global average temperature to a level well below 2oC above pre-industrial levels, but also an innovative architecture that gives contracting parties considerable flexibility to set their own climate change goals.
