Brochure, flyer, fact-sheetEnhancing countries’ capacity to report to the United Nations Framework Convention on Climate Change on greenhouse gas emissions for the Agriculture, Forestry and Other Land Use sector: Colombia 2016
Also available in:
No results found.Colombia has submitted two national communications (NCs 2001, 2010) to the United Nations Framework Convention on Climate Change (UNFCCC), providing information on greenhouse gas (GHG) inventories, and measures to mitigate and facilitate adequate adaptation to climate change, among other information. In 2015, Colombia also presented its First Biennial Update Report (BUR), including the REDD+ technical annex. In 2010 and 2012, GHG emissions from the Agriculture, Forestry and Other Land Use (AFOLU ) sector contributed to respectively 58 % and 43% of the national GHG emissions. Since 2013, the United Nations Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries (UN-REDD) and the Mitigation of Climate Change in Agriculture (MICCA) Programmes have provided support to Ecuador for the preparation and reporting of the national GHG inventory (NGHGI), AFOLU component, to the UNFCCC. This brief relates the implemented activities and fruitf ul collaboration that were fundamental in assisting Ecuador in successfully meeting its commitments to the UNFCCC reporting process for the Agriculture and LULUCF sectors. -
ArticleThe consolidated European synthesis of CO2 emissions and removals for EU27 and UK: 1990-2018 2020
Also available in:
No results found.Reliable quantification of the sources and sinks of atmospheric carbon dioxide (CO2), including that of their trends and uncertainties, is essential to monitor the progress in mitigating anthropogenic emissions under the Kyoto Protocol and the Paris Agreement. This study provides a consolidated synthesis of estimates for all anthropogenic and natural sources and sinks of CO2 for the European Union and UK (EU27 + UK), derived from a combination of state-of-the-art bottom-up (BU) and top-down (TD) data sources and models. Given the wide scope of the work and the variety of datasets involved, this study focuses on identifying essential questions that need to be answered to properly understand the differences between various datasets, in particular with regards to the less-well characterized fluxes from managed ecosystems. The work integrates recent emission inventory data, process-based ecosystem model results, data-driven sector model results, and inverse modeling estimates, over the period 1990–2018. BU and TD products are compared with European national GHG inventories (NGHGI) reported under the UNFCCC in 2019, aiming to assess and understand the differences between approaches. For the uncertainties in NGHGI, we used the standard deviation obtained by varying parameters of inventory calculations, reported by the Member States following the IPCC guidelines. Variation in estimates produced with other methods, like atmospheric inversion models (TD) or spatially disaggregated inventory datasets (BU), arise from diverse sources including within-model uncertainty related to parameterization as well as structural differences between models. In comparing NGHGI with other approaches, a key source of uncertainty is that related to different system boundaries and emission categories (CO2 fossil) and the use of different land use definitions for reporting emissions from Land Use, Land Use Change, and Forestry (LULUCF) activities (CO2 land). At the EU27 + UK level, the NGHGI (2019) fossil CO2 emissions (including cement production) account for 2624 Tg CO2 in 2014 while all the other seven bottom-up sources are consistent with the NGHGI and report a mean of 2588 (± 463 Tg CO2). The inversion reports 2700 Tg CO2 (± 480 Tg CO2), well in line with the national inventories. Over 2011–2015, the CO2 land sources/sinks from NGHGI estimates report −90 Tg C yr−1 ± 30 Tg C while all other BU approaches report a mean sink of −98 Tg yr−1 (± 362 Tg C from DGVMs only). For the TD model ensemble results, we observe a much larger spread for regional inversions (i.e., mean of 253 Tg -
