Abstract
This study was aimed at contributing to the efforts directed at managing Carbon(iv) oxide, CO2
emission by assessing the CO2 emissions and management strategies in the Nigerian
manufacturing industries using some selected industries at Agbara Industrial Estate, Ogun state.
The main objectives of the study are to determine the amount of CO2 emitted from the stationery
sources of the selected industries in the study area between the periods of June 2015 to May
2016, and to compare this amount with the inclusion threshold i.e. the maximum allowable
amount of CO2 emission of various emission management programmes around the world. The
study also checked for the performance of each of the industry as regards CO2 management best
practices. The industries were grouped into different industrial strata according to Manufacturers
Association of Nigeria industrial classification, after which one industry was picked per stratum.
Five industries namely; Industry N, Industry G, Industry Q, Industry D and Industry P were
randomly selected using dip in the basket method from a total of seventeen industries for the
study. The identity of the industries was concealed due to security reasons. The use of
documented emission factors in measuring CO2 emission was the adopted method in this work.
Twelve months’ fuel consumption records of each emission source from each selected industry
was collated and examined, this was then used to calculate the CO2 emission for each emission
source by multiplying the monthly volume/mass (as the case may be) of the fossil fuel
combusted with the appropriate emission factor. The performance of each of the industry as
regards CO2 management best practices was assessed using a GHG best management practice
checklist adapted from that of the World Wildlife Fund which was used for their Low Carbon
Manufacturing Programme. Results showed that Industry N emitted a total of 7714.65 tones of
CO2, Industry G emitted 45,055.45 tones of CO2, Industry Q emitted 8,200.94 tones of CO2,
Industry D emitted 53,195.54 tones of CO2 and Industry P emitted 49,247.78 tones of CO2
during the studied period. These figures are larger than the inclusion threshold of many carbon
management programmes around the world. Statistical significance findings showed that natural
gas fuel and natural gas combusting stationery equipments are the major contributors of the CO2
emitted in the assessed industries. Also all the industries practice a poor CO2 emission
management. The study concluded that a significant amount of CO2 was emitted by the assessed
industries and these were majorly contributed by natural gas fuel combustion, the industries also
practice a very poor CO2 emission management. It is therefore recommended that industries
should focus their attention on natural gas and natural gas combusting sources for their emission
management activities, environmental regulators should develop an emission
standards/programme where a cap or a predetermined maximum allowable amount of CO2 is
allocated to industries and there is need for consideration of the other greenhouse gas emissions
in subsequent studies.
