Abstract: The flaring of oil-associated gas continues to generate insidious environmental and energy consequences against efforts toward sustainable development for Nigeria. This study compared some of the economic benefits lost due to flared gas at flow stations with fuelwood energy consumption. The objectives were to assess comparative cost suffered by host communities, estimate greenhouse gases emissions of burnt-off gas and evaluate possible effects of post-global financial meltdown support policies on climate change. Parameters for evaluating the environmental and energy impacts were measured directly or collected from flow stations through opinion surveys and meetings. An inventory of the motors, voltages and power ratings of the machines used at the flow stations was made, with a view to quantifying the energy involved in drilling operations. For estimation of health risks and gaseous emissions, SIMPACTS method was used. Results from the study show that an annual average of 2040 MJ of fuelwood is consumed in Nigeria, 77.3% of the sourcing is done by children and the time spent in fuelwood trips is between 4 and 5 h, at a frequency of three to four times a week. This amount of fuelwood consumed examined alongside 2.5billion standard cubic feet of gas flared per day, revealed the quantity of energy that ought to be saved and related avoidable extreme weather conditions that prevail in Nigeria. Therefore, gas flaring violates the tenets of sustainable development and seriously contributes to global warming. In conclusion, flare down can be achieved by utilizing micro-gas turbines, re-injection and pursued as part of a new agenda for responsible governance in Nigeria.
