ABSTRACT
The purpose of this study is to investigate the effect of corporate governance on environmental
disclosure of listed companies in the Nigerian oil and gas sector. Secondary data from the
annual reports and financial statements of the publicly traded firms for a period of ten years
(2013-2022) was used as the main source of data collection. Ten (10) oil and gas companies
listed on the Nigerian Exchange Group (NGX) were chosen using census sampling technique
because all the listed oil and gas companies were included in the study. Mean and standard
deviations were used to answer the research questions while simple linear regression and
multiple linear regression was used to test the hypotheses of the study. Contrary to initial
expectations, the research documented that all variables (Table 4.16), including board
independence (β = -0.067, t-value = -0.495, p = 0.05, sig = 0.622), board size(β = -0.003, tvalue = -0.021, p = 0.05, sig = 0.983), board meeting(β = 0.004, t-value =
0.030, p = 0.05, sig = 0.976) and board gender diversity (β = 0.050, t-value = 0.370, sig. =
0.712) showed statistically insignificant effects on environmental disclosure practices. As a
result, the study’s conclusion is that corporate governance does not exert a significant
influence on environmental disclosures. These study recommends for a deeper understanding
of the intricate dynamics between corporate governance and environmental disclosure in the
context of the oil and gas industry in Nigeria.
