Abstract: Land use change and forestry (LUCF) is one of the key sectors to report national greenhouse gases (GHG) inventory as required by the United Nations Framework Convention on Climate Change (UNFCCC). With the aim to further implement the GHG emissions reduction target assigned to all provinces in China, it is an important basic work to estimate the GHG emissions by sources and removal by sinks, and their present situations and distributions at provincial level, that is, to prepare provincial GHG inventory in LUCF sector. The methodology of compiling provincial GHG inventory in LUCF sector is developed to estimate anthropogenic GHG emissions by sources and removal by sinks from LUCF activities at provincial level in China, which mainly includes carbon stock changes in forest and other woody biomass, and GHG emissions caused by forest conversion. The methodology is in compliance with IPCC guidelines on national GHG inventory and incorporated with actual specialty of LUCF activities in China, especially fully considers the availability and reliability of key activity data at provincial level. The methodology also supplies provincial specific defaults of key emission factors. The methodology makes it scientific and operable to compile LUCF GHG inventory at provincial level in China.
