Gas Flaring Costs and Financial Perfromance of Oil and Gas Companies in Nigeria

This study examined the effect of environmental costs on the financial performance of listed oil and gas companies in Nigeria, using Return on Assets (ROA) as the proxy for financial performance. The specific environmental cost variables considered were Environmental Health and Safety Costs (EHSC), Waste Management Costs (WMC), and Environmental Impact Assessment Costs (EIA), while firm size (LOGTA) was included as a control variable. The study adopted an ex-post facto research design and relied on secondary data extracted from the annual reports of sampled oil and gas firms covering the period under review. Data were analyzed using descriptive statistics, unit root tests, diagnostic tests, and Ordinary Least Squares (OLS) regression technique.The descriptive statistics revealed that ROA had a mean value of 0.3238, while EHSC, WMC, and EIA recorded mean values of 2,319.662, 10,960.51, and 57,452.17 respectively, indicating substantial variation in environmental spending across firms. The regression results showed that Environmental Health and Safety Costs had a negative and insignificant effect on ROA (β = -0.00002, p = 0.5673, R² = 0.029989). Waste Management Costs also exhibited a negative and insignificant effect on ROA (β = -0.00001, p = 0.3798, R² = 0.035605), while Environmental Impact Assessment Costs had a negative and insignificant effect on ROA (β = -0.000001, p = 0.5324, R² = 0.030782). Overall, the explanatory power of the models was low, with each variable explaining approximately 3% of the variation in ROA.The study concludes that environmental cost components do not have a statistically significant effect on the financial performance of oil and gas companies in Nigeria during the period examined. This suggests that such expenditures are largely compliance-driven and do not immediately translate into improved profitability. The study recommends that firms adopt more efficient environmental management practices that enhance cost effectiveness while ensuring regulatory compliance, and that policymakers strengthen environmental regulations to encourage more impactful environmental investments
