Abstract
In views of the deterioration of global warming, the issue of reducing CO2 emission have been prevailing. Vehicle/Transportation is considered as the second major source of CO2 emission in the US. This project aims at examining what part of vehicle specification will have correlation and regression relation with the CO2 emission.
With correlation analysis, Engine Displacement and Cylinder are found to have positive relation with CO2 emission, whereas the MPG have negative correlation with CO2 emission. The regression relationship among CO2, Displacement, Cylinder, and MPG are found to be significant due to relatively large r square value and small p-value.
The results and finding may be referenced by vehicle manufacturers to refine their design and sustainability consideration. The customers may also utilize the results in making decision of purchasing vehicle with environment protection focus.
