Other Parties are also encouraged to report this information, and developing countries should report information on support needed and received, including its use, impact and results. Several features of the existing transparency system under the UNFCCC will remain in place, such as reporting of greenhouse gas (GHG) inventories and biennial tracking of progress towards mitigation and support-related objectives. An important difference is that the future transparency framework will apply to all Parties, with flexibility in terms of the scope and frequency of reporting and scope of review.
