This study investigates the effects of improved driving behaviors on greenhouse gas (GHG) emissions reduction from light vehicles in Kuwait. There has been a steady increase in Greenhouse Gases (GHG) emission to the atmosphere globally since the industrial revolution. Human activities, such as the burning of fossil fuels, transportation, and changes in land use are major contributors to the increase in concentrations of atmospheric GHGs. According to the latest estimates, Kuwait being a major oil producing country, annual increase in GHG emissions has been recorded for the past two decades, with 21.2 MT per capita emitted in 2020, increased from 21.1 compared to 2019. Implementing practical and feasible reduction strategies to the significant emission contributors is essential. This study proposes a management system targeting the transportation sector through enhanced driving behaviors in a transportation fleet, using a monitoring hardware and software, to collect data from 25 light vehicles. To assess the solution's effectiveness, we compared pre- and post-intervention periods of fuel consumption in light vehicles through monitoring and enhancing the driving behavior variables, harsh acceleration, harsh braking, over-speeding, and idling, thus reducing carbon emissions that was determined based on the US EPA conversion factor. Our results show significant improvements in several key parameters, a 15% reduction in fuel consumption resulting in 15% and 18% carbon dioxide emissions (CO2) and cost reduction, respectively. This should represent huge environmental and economic benefit associated with the measures implemented. In the post-intervention phase, where controls and interventions were implemented to enhance drivers' behaviors, there was a significant reduction in idling hours, decreasing by 8,167.38 hours with a (P < 0.003). These results clearly illustrate the need for more stringent national regulations at improving driving behaviors, which not only contribute to environmental quality improvement but also offer substantial economic advantages.
