Carbon footprint labelling certification of railway operating service in Korea

초록

In Korea, the carbon footprint labelling certification system of product and service has been introduced from 2009. The aim of this study was to certify the carbon footprint labelling of railway operating service. Targets of railway operating service were KTX (Korea Train eXpress) from Seoul to Busan as a long-distance travel and Nooriro (electric multiple unit) from Seoul to Sinchang as a short-distance travel. The calculation criteria of carbon footprint was one-way per one passenger for the travel route of railway operating service. System boundaries were from the manufacture pre-phase to the manufacture phase including the maintenance and the operating service of railcar except for the use and the waste phase. As a result, the carbon footprint of KTX service from Seoul to Busan was 9.98kg CO2/passenger-line and Nooriro service from Seoul to Sinchang was 2.47kg CO2/passenger-line. Most of carbon footprints were resulted from the manufacture phase containing 97% of KTX service and 99.6% of Nooriro service. Now, the carbon footprint labelling for two railway operating service has been promoted to show the advantage of railway as a low carbon emission source compared with other transport modes.
