Abstract
Globally, climate change and its adverse effects on the human population and the environment has necessitated significant research on the sustainable use of natural resources. Gas flaring in Nigeria’s oil and gas industry causes environmental and health hazards and to a large extent, culminates in yearly loss of the Nation’s revenue. The aim of the study is to highlight the potentials of converting flared gas from the Nigerian oil and gas industry to compressed natural gas (CNG) which could be an alternative fuel for the 220 Lagos Bus Rapid Transit (BRT-Lite) while reducing CO2 emissions. In addition, the study provided an overview of gas flaring in the oil and gas industry and energy utilisation in some selected sectors in the country. The Long-range Energy Alternative Planning System (LEAP) software was employed to model the energy demand and carbon dioxide emissions from the BRT-Lite by creating a current scenario and projections to the year 2030. The use of CNG as an alternative fuel for Lagos BRT-Lite will significantly reduce CO2 emissions in Nigeria’s oil and gas industry. Other utilization options for flared gas from this industry includes: Liquefied Natural Gas (LNG), Liquefied Petroleum Gas (LPG), and power generation.

Nigeria is Africa’s most populous country, endowed with large and diverse energy resources, which include crude oil, natural gas, coal and lignite, wind, solar radiation and biomass
5150.6 billion cubic metres [4,5]. This immense gas reserve occurs as associated natural gas or non-associated natural gas which refers to natural gas in a reservoir with little or no crude oil [6]

Summary
Nigeria is Africa’s most populous country, endowed with large and diverse energy resources, which include crude oil, natural gas, coal and lignite, wind, solar radiation and biomass. The reserves of crude oil and natural gas = 36.2 billion barrels and 187 Tscf, respectively [1]. Nigeria’s gas reserves are ranked as the ninth largest with about. 5150.6 billion cubic metres (bcm) [4,5]. This immense gas reserve occurs as associated natural gas (crude oil trapped along with natural gas) or non-associated natural gas which refers to natural gas in a reservoir with little or no crude oil [6]. A greater volume of Nigeria’s gas reserves is found as associated natural gas [7,8]
