The Paris Agreement and its accompanying decision call for Parties to strive to formulate mid-century communicate long-term low-greenhouse gas emission development strategies (LT-LEDS) by 2020. Moreover, the Paris decision requests Parties to communicate a new or updated Nationally Determined...

Common Tabular Formats (CTFs) for the reporting of information necessary to track progress towards Nationally Determined Contributions (NDCs) under Article 4 of the Paris Agreement, including on the use of cooperative approaches, are to be adopted by COP26. This paper explores concrete examples...

The Modalities, Procedures and Guidelines (MPGs) included in Decision 18/CMA.1 adopted at COP24 in 2018 require all Parties to the Paris Agreement to report national greenhouse gas (GHG) inventories using “common reporting tables” (CRTs). The same decision requests the Subsidiary Body for...

The Modalities, Procedures and Guidelines (MPGs) adopted at COP24 in Katowice lay out rules for reporting and reviewing information under the Enhanced Transparency Framework of the Paris Agreement. The Katowice decision on the MPGs requests the Subsidiary Body for Scientific and Technological...

The Modalities, Procedures and Guidelines (MPGs) adopted at COP24 in Katowice lay out rules for reporting and review under the Enhanced Transparency Framework of the Paris Agreement. The Katowice decision on the MPGs requests the Subsidiary Body for Scientific and Technological Advice (SBSTA) to...

Different options of methodological approaches for setting emission baselines are currently under consideration in the international climate negotiations. This paper examines options for baseline approaches for the Article 6.4 mechanism, and draws lessons from how baselines have been used for...

This paper provides a technical analysis of two specific unresolved issues in the negotiations of rules for Article 6 of the Paris Agreement: (i) accounting methods for single- and multi-year NDCs under Article 6.2 and (ii) the implications of a potential transition of activities and units from...

The Paris Agreement states that all countries should strive to formulate and communicate long-term low greenhouse gas emission development strategies (LT-LEDS) and the Paris Agreement’s accompanying decision invites countries to communicate a LT-LEDS by 2020. LT-LEDS are a fundamental tool...

Many Parties to the Paris Agreement have expressed greenhouse gas mitigation targets relative to a baseline scenario, or “baseline targets”. Baseline targets in nationally determined contributions (NDCs) could potentially change over time including to update assumptions of emission drivers...

The enhanced transparency framework for climate action and support envisaged by the Paris Agreement is to “build on and enhance” current transparency arrangements under the United Nations Framework Convention on Climate Change (UNFCCC). This paper draws lessons from current reporting by...
