No. 744: Japanese measuring method of CO2 emissions is approved by ISO (July 3, 2013)

The measuring method of CO2 emissions that Japan proposed under the initiative of the Japan Iron and Steel Federation (JISF) was approved by International Organization for Standardization (ISO) as a new standard. The new standard, ISO14404, specifies the calculation method of CO2 emissions by steel plant and figures in energy-saving facilities that generate electricity using waste heat and by-product gases emitted by blast furnace as the subject for measurement. Currently, it is widespread in Europe to measure CO2 emission by facility, such as blast furnace, converter, and coke oven, but the method to measure by facility cannot consider fully the efforts to introduce energy-saving facilities inside a steel plant. That is, the European model does not take energy saved by effective utilization of newly-introduced facilities into account.

Japan submitted its self-developed calculation method to ISO in 2009, and the Japanese method was finally approved this year. It is evaluated highly because the effect of energy-saving facilities can be calculated easily. With the Japanese method in mind, Japanese steelmakers are proposing the generation facilities that utilize waste heat to newly-industrialized countries like India. It is highly likely that measuring CO2 emissions by facility will stimulate demand for energy-saving technology in steelmaking worldwide.
