Recommendation of Draft Revised Standard Calorific Value and Carbon Emission Factor for Fossil Fuel Energy Sources in Japan: 2013 FY revised standard calorific value and carbon emission factor (Japanese)

Here the author quantified Japanese standard Gross Calorific Value and Carbon Emission Factor for various fossil fuels used in Japan upon the request of the Ministry of Economy, Trade and Industry and the Ministry of the Environment under the cooperation of relevant industrial organizations by the request of these Ministries, using real measured physical and chemical data and calorific value in 2013. The revised standard values have several unique natures compared to the current one as follows; - The standard values are comprehensive and clearly traceable from the real measurement data of physical, chemical characteristics and calorific value of fuels and the data process and treatment. - The gross calorific value and carbon emission factors are simultaneously measured from the same samples in a consistent manner, different from the current standard values. - The interpolation and approximation equations are estimated using these data and that enabled estimation for minor energy sources and adjustment of small changes of physical, chemical characteristics for major energy sources. As a result, highly accurate and up to date standard gross calorific value and carbon emission factor are measured for various fossil fuels used in Japan listed in the current standard. So the author recommends the revision of the standard values. Moreover, based on the revision works, the author proposes several changes and amendments of energy origin CO₂ emission quantification and estimation process in Japanese greenhouse gas inventory systems under the UNFCCC.
