Climate related financial risk is increasingly relevant to oil dependent economies because it can  affect asset valuation, future cash flows, impairment testing, provisions, contingent liabilities,  and broader corporate reporting quality. In Nigeria, where the oil and gas sector remains central  to public revenue and foreign exchange earnings, the growing exposure to physical climate stress  and transition pressure has intensified concern about how climate related losses are recognized  and disclosed in financial statements. This review examines the relationship between climate  risk, financial loss recognition, and disclosure practices in Nigeria’s oil and gas industry, with  particular attention to impairment, provisions, contingent liabilities, and regulatory readiness. A  structured literature search covering 2021 to 2026 was conducted to identify recent studies on  climate related reporting, gas flaring, sustainability disclosure, and financial reporting  implications in the Nigerian and broader oil and gas context. The reviewed literature indicates  that while climate related disclosures in financial reports have increased, the depth, consistency,  and decision usefulness of those disclosures remain uneven. Several studies show that firms in  the oil and gas sector continue to provide limited sustainability information, with climate change  and pollution effects often reported in a superficial or fragmented manner. This weak disclosure  environment reduces transparency for investors, regulators, and other stakeholders who need to  understand the financial consequences of climate exposure. The review also highlights the  materiality of gas flaring as both an environmental and economic burden, with recent evidence  showing substantial cumulative emissions and large direct revenue losses, thereby reinforcing the  financial significance of climate related harm in the sector. In addition, the broader literature  suggests that carbon sustainability reporting is increasingly tied to the transition toward net zero  and to corporate accountability in high emitting industries. Overall, the review demonstrates that  a major gap persists between the economic reality of climate related losses and the way these  losses are reflected in financial reporting practice. Strengthening recognition, measurement,  disclosure, and enforcement mechanisms is therefore essential for improving reporting quality,  supporting informed decision making, and enhancing regulatory credibility in Nigeria’s oil and  gas industry.
