An investigation on well-to-wheel emissions of passenger cars in Turkey.

Passenger cars are responsible for a great amount of energy consumption and emissions in the world. Turkey is one of the world's twenty largest emission producers. The reason behind this study is to determine the most appropriate energy source for passenger cars particularly in Turkey in terms of main vehicle emissions. The results will be supportive for general inferences also. The impact of technological year, vehicle type, fuel type, fuel production, and electricity generation from different energy sources on well-to-wheel emissions for Turkey has been analyzed using the GREET software in this study. In the realization of emission analysis, transportation statistics of Turkey in the last 10 years have been evaluated. In addition, different scenarios have been presented for the years 2030 and 2050. It is found that average emissions emitted from passenger cars in Turkey decrease by year, and the use of LPG and CNG in plug-in hybrid cars generates lower emissions in future scenarios.
