This report covers the technical assessment of the voluntary submission of Belize on its proposed forest reference level (FRL) in accordance with decision 13/CP.19 and in the context of results-based payments. The FRL proposed by Belize covers the activities reducing emissions from deforestation, reducing emissions from forest degradation, conservation of forest carbon stocks, sustainable management of forests and enhancement of forest carbon stocks, which are the five activities included in decision 1/CP.16, paragraph 70. For its submission, Belize developed a national FRL. The FRL presented in the submission, for the reference period 2016–2020, corresponds to 4,606,875, 4,850,928, 5,094,981, 5,339,034 and 5,583,087 tonnes of carbon dioxide equivalent for 2016, 2017, 2018, 2019 and 2020, respectively. The assessment team notes that the data and information used by Belize in constructing its FRL are mostly transparent, complete and in overall accordance with the guidelines contained in the annex to decision 12/CP.17. This report contains the assessed FRL and a few areas identified by the assessment team for future technical improvement in accordance with the provisions on the scope of the technical assessment contained in the annex to decision 13/CP.19.
