Belize is currently attempting to transition to a low carbon economy by implementing an electric transportation strategy that is to increase the users of electric vehicles. This study sought to analyze the cost effectiveness of a battery electric vehicles (BEV) against an internal combustion engine vehicle (ICE vehicle) as well as evaluate the demands of users for purchasing battery electric vehicles in Belize. This was done for the consumers in Belize by using the analytic technique and surveying tools of cost benefit analysis (CBA), analytic hierarchy process (AHP), and stated preference survey (SPS).
CBA is used to measure the costs and benefits of the decision in purchasing BEV to replace ICE vehicles, and AHP technique is used for the selection of BEV and prioritization of six criteria including purchase cost, life expectancy, access to charging stations, travel range, charging time, and carbon dioxide reduction. The use of stated preference survey (SPS) is to survey how customers might behave in five models of BEV selection by showing their preference. Results indicate that the BEV is more cost effective over its 5-year lifetime than ICE vehicles in Belize. According to the survey from this study, many Belizean consumers would consider having an electric vehicle as their next car purchase, however, they are much concerned about the purchase cost of BEV. The necessary incentive policies must be implemented to decrease the initial cost of the electric vehicle, thus increasing its adoption in Belize. One the primary measures is purchase subsidies including tax rebates of vehicle purchase to reduce the price gap with conventional vehicles. To increase marketability of electric vehicles entering Belize’s automobile market, it is suggested that the purchase price is within the range of $36,000- $43,185, the travel distance at least 249 miles and the most preference BEVs are SUVs and sedans.
For moving towards a low carbon country, reduction of carbon dioxide CO2 emissions from transportation is a necessary policy in Belize. This study indicates that Belize’s electricity generation mix boosts the BEV’s effectiveness in reducing annual CO2 emissions. This finding demonstrates that BEV can play a critical role in reducing Belize’s carbon footprint, specifically within the transport industry, thus can be of great influence in Belize realizing one of its INDC (intended nationally determined contributions) goals, which is lowering energy concentrations within transport by endorsing conversion to sustainable transportation. The results of economic analysis and the findings of Belizean consumers’ demands from this study could provide a valuable information for the authorities of Belize in promoting electric vehicle strategies. |
