The current air pollution increase prompts scientists to look for new candidates for highway alignment that would eventually result in reduced vehicle fuel consumption. In the current study, an empirical and computational method has been proposed which needs to be implemented simultaneously with the alignment optimization process so that different alignment candidates could be assessed in terms of fuel consumption of vehicles. The results obtained from the final equation indicate the total cost of CO2 clean-up required for each vehicle in each highway candidate and these costs could be compared to each other to determine the best candidate of highway.
