In this feasibility study, a feasibility study of alternative fuels to replaced the use of diesel fuel by in trucks was conducted to reduce pollutants in from the transportation sector. Liquified petroleum gas (LPG) was considered used for small tonnage class trucks,, and liquified natural gas (LNG) w as considered used for the medium medium- to to large-tonnage class of trucks. The availability and affordability of these two types of fuel for trucks were determined analyzed from both an through economic and profitability analysesperspective. As a result of these this analysises, it was determined that the use of these alternatives to relative to the use of diesel fuel by trucks met were both the economic feasibilfeasibleity and profitable. ility requirements. Based on these findings, this study presented presents reasonable alternatives to the use of diesel fuel by both small small-tonnage trucks and medium- to large-tonnage trucks.
