ASSESSMENT OF MILLENNIUM DEVELOPMENT GOAL 7 IN THE NIGER DELTA REGION OF NIGERIA VIA EMISSIONS INVENTORY OF FLARED GAS
Abstract
Emissions released into the atmosphere from gas flaring in the Niger Delta Region (NDR) of Nigeria have adversely affected the environment and well-being of the inhabitants. This present study aimed at employing the emission inventory of flared gas in this region to assess the level of achievement of Millennium development goal (MDG) 7 with respect to sustainable environment. Greenhouse gas (GHG) and black carbon (BC) inventory of the region was estimated from gas flared data sourced from Nigeria National Petroleum Corporation using empirical formula and emission factors obtained from literature. For the period in view (1990-2014), a total estimate of 1.80 x 109 tons of CO2 equivalent (tCO2 e) was released into the atmosphere from the flaring of 555.74 Bcm of gas. Relative uncertainty of the emission was between -92.2% and 51.16%. It was observed that the present (2014) quantity of emissions has reduced by 49.71% (3.61 x 107tCO2 e) compared to the emissions (7.26 x 107tCO2 e) for the year 1990. The results showed that MDG-7 on environmental sustainability in the NDR is progressing well with considerable emission reduction achieved through increased utilization of gas in the country to reduce the volume of gas flared.
