Abstract

'Climate change' means a change of climate which is attributed directly or indirectly to human activity that alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods. ‘Greenhouse Gas’ is main anthropogenic cause of Global Warming and Climate Change of the Ecosystem, 'The Earth'. International society and UN have focused on the Greenhouse Gases ― CO2, CH4, N2O, HFCs, PFCs, SF6 ―, and made many efforts to mitigate the Climate Change by lowering the greenhouse gas inventory with international cooperation. They started to organize UNEP, WCED to arouse the issue of the development and environment problem, and finally IPCC (Inter-governmental Panel on Climate Change) to support UNFCCC with information and knowledge by expert working group and research activities. IPCC developed and improved some guidelines to evaluate national greenhouse gas inventory since 1995 to get more complete, consistent, comparable, tranparent and accurate greenhouse gas emission and removal calculation results of each country. It paid attention to the effect of 'Harvested Wood Products(HWP)' as the sink of Carbon Dioxide sequestration and developed the approaches and calculation formula for the HWP with carbon conversion factor and half life. Consequently, 2006 IPCC guidelines and 2013 KP supplementary and Good Practice Guidance are the officially accepted two evaluation tools with different HWP sorting accompanied with different conversion factor, half life and tier classification. Comparison of the greenhouse gas inventory data from these evaluating tool would be meaningful to supply measurable, reportable and verifiable greenhouse gas inventory including the effect of HWP for each country during Paris Climate Agreement era.
