REGIONAL DECOMPOSITION ANALYSIS OF CO2 EMISSION DRIVERS IN THE SOUTH-SOUTH AND SOUTH-EAST MANUFACTURING INDUSTRIES.
Abstract
Regional inequalities play a significant role in driving carbon emission in various forms such as; economic scale, social infrastructure and political disparities among regions. Hence, the current research explored the influencing drivers of carbon dioxide (CO2) emissions and regional disparities between South-south and South-east manufacturing sector in Nigeria from 2009 to 2016. Using the extended Kaya identity and the Logarithmic Mean Divisia Index method, the influencing drivers of carbon emission were decomposed into regional manufacturing output, regional industrial share, energy intensity, energy (fuel) mix and emissions factor. The result indicates that CO2 emissions decreased from 706.97 TCO2 in 2009 to 653.51 TCO2 in 2016 (- 0.008% decrease), with an annual average reduction of -0.08% for the south-south. While in the south east, CO2 emission increased from 339.17TCO2 to 351.39TCO2 with an annual average increase of 0.036%. Among fossil energy mixes utilized, the share of fuel (PMS), diesel (AGO), and kerosene (HHK) accounted for 28.27%, 25.46% and 31.33% in the south-south; whereas in the south-east; these fossil energies constituted 16.39%, 55.12% and 19.01% respectively. Furthermore, regional industrial share and regional manufacturing output contributed to the increase of emissions in the south-south with 398.48 TCO2 and 191.40TCO2. Adversely, energy intensity and fuel mix reduced emissions with -635.53 TCO2 and -8.80 TCO2 respectively. Whereas in the south-east region, regional industrial share, regional manufacturing output and energy (fuel) mix increased CO2 emissions with 189.41TCO2, 105.12TCO2, 1.18TCO2, while energy intensity reduced emissions by -238.48TCO2. Carbon emissions factor in both regions was insignificant. Although, the effects or impacts of the decomposed drivers vary across the different sub sectors across the two regions. Based on the findings, the research recommends that industries and then manufacturing sector should be encouraged to invest in cleaner and renewable energy.
