The Consultative Group of Experts on National Communications from Parties not included in Annex I to the Convention, with the assistance of the secretariat, conducted three regional training workshops in 2016 on the preparation of biennial update reports (BURs) from Parties not included in Annex I to the Convention. For the Africa region the workshop was held in Lomé, Togo, from 22 to 24 February; for Asia-Pacific and Eastern Europe the workshop was held in Colombo, Sri Lanka, from 4 to 6 April; and for Latin American and the Caribbean the workshop was held in Rodney Bay, Saint Lucia, from 4 to 6 July. The aim of these workshops was to enhance the capacity of national experts in using the “UNFCCC biennial update reporting guidelines for Parties not included in Annex I to the Convention” to facilitate the preparation of their country’s BUR and to serve as a platform for the exchange of views, lessons learned and experiences relating to the process of, and preparation of, BURs. This report outlines the proceedings of the workshops and includes a summary of the discussions.
