Extended exergy analysis of Turkish transportation sector

This work presents an analysis of the different modes of the Turkish transportation sector along the guidelines of the Extended Exergy Accounting (EEA) method. The results refer to year 2006 because that was the most complete and sufficiently disaggregated database available. The evaluation of the transportation sector leads to the calculation of its extended exergetic efficiency (EEAeff) and requires the inclusion of all commercial and private transportation services (passengers and goods) as well as of all services directly related to transportation (post, cargo, pipeline transport, etc.). The environmental remediation costs (EEEnv) of sectoral solid waste and gas emissions (direct and indirect) are obtained in accordance with the original calculation procedure, without recurring to the conversion of monetary into exergetic costs. The resulting EEAeff of the sector is 0.36, which is rather low (in the EE sense), because of the sector’s largely unsustainable structure: fossil-fuelled road transportation widely prevails, which not only destroys a very high percentage of the incoming exergy, but is also affected by quite large CO2-equivalent emissions that demand for a high EEEnv.
