In the framework of Lebanon’s Third National Communication to the United Nations Framework Convention on Climate Change (UNFCCC), Greenhouse Gas (GHG) emissions resulting from the Land Use, Land-Use Change and Forestry Sector (LULUCF) in Lebanon were estimated for the period of 1994-2011. The tier 1 approach of the Intergovernmental Panel on Climate Change (IPCC) Guidelines was adopted in the calculation of GHG and consequently for the development of the National Greenhouse Gas Inventory. The sources of emissions as well as the main removals in this sector were identified in the purpose of targeting the largest contributors. This allowed the development of the potential mitigation actions for the reduction of GHG emissions and for increasing the carbon sequestration effect of the LULUCF sector.
