Good systems for tracking NDCs are critical to support requirements to account for and report on progress towards meeting the NDCs under the Paris Agreement. Countries will need to build upon and enhance existing domestic MRV systems for this purpose, but face a number of challenges. New areas, such as tracking of adaptation and support and the development of respective indicators, are a challenge for countries. Common rules for tracking must be agreed upon and capacity must be built in these areas. Emissions projections that build on existing data are an emerging challenge as well. Countries have set up existing inventories but projecting emissions to link them to mid- or long-term actions needs more granular data and does not work with existing data. Countries also lack capacity for projections. Emission inventories can be produced at many different levels. There are some overlaps in various reporting systems but often countries pursue separate systems for national inventories, and the private sector and other potential tracking needs exist. Countries need to either integrate them or can feel overwhelmed with the different reporting requirements and numbers of systems. Data gaps still exist. Basic data that can be used for emission inventories does not reflect the impacts of implementation of actions leading to a mismatch between the reports on national and international levels. Also inventories might exclude HFCs or other greenhouse gases which are important for some sectors. Organizations in the data and transparency thematic working group support countries to address these challenges and develop strengthened systems to track the implementation and effects of their NDCs, report their results accordingly to domestic and international constituencies, and prepare for future NDCs.


Objectives of the thematic working group

  • Development of systems for tracking and monitoring of NDCs

  • Strengthening and building MRV and GHG accounting systems

  • Strengthening collecting and processing of data and methods

  • Advancement of emission projections and scenarios development


Insights into the work 

General description

The data and transparency thematic working group is comprised of implementing partners working to build a coherent approach to data and transparency support. Partners include Center for Clean Air Policy (CCAP); Climate Analytics; Climate Development and Knowledge Network (CDKN); Energy research Centre of the Netherlands (ECN); Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH; New Climate Institute (NCI); United Nations Development Programme (UNDP); and World Resources Institute (WRI). The group agreed to convene every two months, taking advantage of climate negotiations to meet in person when possible. WRI leads the working group and arranges call-in details and other logistics. Coordination calls include a ‘tour de table’ of the status of the various partner projects and discussions on priorities and areas for collaboration. Partners have shared experiences and ideas on how challenges can be addressed. For example, partners noted best practice examples are needed to help with the building of national emissions inventory systems. It can also be useful to establish bilateral and regional links as countries can work together on projects in their respective regions. Additionally, a network of MRV experts to foster collaboration and peer-exchange would be helpful for practitioners in general.



WRI is managing the Data and Transparency Working Group under the IKI NDC Cluster and had regular calls in 2017, as well as met in Berlin in May, and in Bonn in November, to establish the modalities of the work group and share information. Over the course of these meetings, partners shared priorities for data and transparency work although many current project activities are still being designed and agreed upon with countries. Participants to the meetings have achieved greater awareness of partner tools, resources and research as well as events, workshops, and webinars to avoid duplication and conflicts. Additionally, partners discussed and identified possible roles and responsibilities for responding to country queries thought the help desk. The working group also conducted a survey to country transparency leads to assess how they would like to engage in the working group. The group is also considering options for webinars and workshops to share resources and updates to countries. In addition to regular calls, participants will continue to share documents and updates to an email list of partner organizations on regular basis.

The group is continuing coordination calls during 2018, and met in Bonn in May. A joint workshop with the Political and Institutional Frameworks working group was held in June in Washington, DC. This workshop focused on how to improve vertical and horizontal integration for effective NDC implementation.
