In the United Nations Framework Convention on Climate Change (UNFCCC) process, all countries have obligations to report on their actions to address climate change and its impacts and to take part in review processes that consider the information Parties provide. The Paris Agreement establishes an enhanced transparency framework that will build on this system of reporting and review. Least Developed Country (LDC) Parties alongside all other Parties will have new reporting obligations to consider under the enhanced transparency framework which will have a more comprehensive approach to transparency around climate action and support to enable those actions. This guide provides practical information to help prepare various reports and communications under the UNFCCC as well as take part in the relevant review processes. It also provides a glimpse into the on going negotiations to develop the enhanced transparency framework under the Paris Agreement and some of the implications for those preparing reports and communications for their countries.
