Estimation of carbon dioxide emissions using liquefied petroleum gas (LPG) in some Libyan cities as an alternative fuel

Abstract

This study assessed the use of liquefied petroleum gas (LPG) as an alternative fuel to petrol. in the transport sector, focusing on environmental and economic aspects and its potential application in certain Libyan cities. Liquefied petroleum gas is considered a relatively cleaner fuel, as it is characterized by lower emissions of harmful gases compared to petrol The practical aspect of the study involved comparing carbon dioxide emissions resulting from the use of petrol and LPG in a number of Libyan cities with high traffic density, namely: Tripoli, Benghazi, Misrata, Zawiya, Sabha, Al-Khums, and Tobruk. Emissions were calculated. on the assumption that each vehicle travels 100 kilometres per day, comparing the consumption of petrol and LPG and the emissions resulting from each. The results showed that the use of LPG reduces carbon dioxide emissions by approximately 22% compared to petrol, with emissions falling from around 15.525 kg CO₂ to 12.1kg CO₂ per 100 kilometres per vehicle. The study also indicated that a partial switch of up to 25% of the total vehicle fleet could achieve a significant reduction in emissions within Libyan cities. The study concluded that liquefied petroleum gas (LPG) represents a practical and phased option for reducing environmental pollution and cutting traditional fuel consumption in Libya, particularly given the availability of local oil and gas resources.
