Comparative analysis of green house gas emission from different vehicular fuels

© 2018 IEEE. Every growing economy has growing need for mobility. However, the over dependence of the transportation sector on fossil fuels have significant impact on the overall GHG emission. It is estimated that the transportation sector contributes 26% of total GHG emission annually. In addition to that, pollution levels of several major cities have augmented significantly. Since the ratification of the Paris Agreement at COP 21, the transportation sector has seen a rapid move towards 'clean and green' technologies and sustainable fuel types. This paper attempts to project the total GHG emission levels and particulate matter of light vehicles entering Noida Toll Bridge for the year 2021. GREET (Green House Gases, Regulated Emissions, and Energy use in Transportation) model is used for GHG emission calculations. The calculation is carried out on the basis of Well-to-Wheel (WTW) analysis for each fuel type. The alternate vehicular fuel technologies considered for this study include CNG, Bio-diesel 20% (BD20), LS Diesel and electricity. A comparative analysis is also drawn between the fuel mixes. It is observed that though EVs have zero-emission level during operation, they have a significant contribution to GHG emission if the electricity consumed by the EVs is generated by conventional power plants.
