Ultimately, the «national» nature of the parties` NDCs, despite efforts to limit national discretion and the paralysis of ICTU and accounting, continues to give the parties considerable leeway and may call into question the evaluation, aggregation and comparison of CNN. 3 Office of the Spokesperson, Department of Foreign Affairs of the United States, «Notification of the intention to withdraw from the Paris Agreement» (August 4, 2017) . — Legally binding: on many issues, the Paris Agreement authorizes its meeting of the contracting parties to adopt binding rules. But the question of whether the parties would choose to exercise this power within the Rules of Paris remained open during the negotiations. This debate was repeated by a disagreement over how to characterize the subject of the negotiations — in terms of «Paris rules» or «Paris guidelines». Footnote 23 1 The full sentence of decisions adopted in Katowice can be found in the Katowice Climate Package (UNFCCC) . 4 F Maisonnave, «Brazil to verify the status of the Paris Agreement, declares bolsonaro Minister of the Environment» (Climate Home News, December 9, 2018) . With regard to the examination of the positions of nearly 200 parties, it is not easy to reach agreement on such a complex and technical document. In these circumstances, every step forward has been a great success — said Michael Kurtyka, President of COP24.
With regard to another long-standing bone of contention between developed and developing countries, that is, justice, the Paris rules preserve the position of all parties. The annex requires the parties to report on how they have approached issues of fairness and ambition, footnote 50, but does not require specific types of information to support a party`s narrative, as this would have required agreement on indicators of fairness, which proved impossible during the negotiations. Therefore, a party`s explanation of why it considers its NDC to be fair and ambitious is self-determined and based on self-chosen benchmarks. Footnote 51 Although the ICTU guidelines do not prescribe or restrict what the parties can say about fairness and ambition, the simple requirement to provide an explanation allows for more targeted criticism. Footnote 52 23 This tension was reflected in the UNITED Nations press release on the Katowice result, which referred to «the set of guidelines adopted, which some refer to as «rules». UN News, «At COP24, countries agree on a concrete way to bring the Paris climate agreement to life» (December 15, 2018) . 90 For an informative perspective, see S Biniaz, «The Who, What and Wann of» Flexibility in the Paris Agreement`s Transparency Framework` Climate Law Blog (Sabin Centre for Climate Change Law, 20 December 2018) . Article 14 of the Paris Agreement requires the meeting of the contracting parties to «regularly draw up an inventory of the implementation of this agreement in order to assess the progress made together in achieving the objective of this agreement and its long-term objectives.» Footnote 99 This global inventory plays a key role in the «round of ambition» of the agreement, conducting a five-year assessment of the parties` joint progress, which is to inform the parties about updating and improving their NPNS and their support.
